Overview

Cosmos

Cosmos is a heterogeneous network of many independent parallel blockchains, each powered by classical BFT consensus algorithms like Tendermint. Developers can easily build custom application specific blockchains, called Zones, through the Cosmos SDK framework. These Zones connect to Hubs, which are specifically designed to connect zones together.
The vision of Cosmos is to have thousands of Zones and Hubs that are Interoperable through the Inter-Blockchain Communication Protocol (IBC). Cosmos can also connect to other systems through peg zones, which are specifically designed zones that each are custom made to interact with another ecosystem such as Ethereum and Bitcoin. Cosmos does not use Sharding with each Zone and Hub being sovereign with their own validator set.

(There's a youtube video with a quick video overview of Cosmos on the medium article - https://medium.com/ava-hub/comparison-between-avalanche-cosmos-and-polkadot-a2a98f46c03b)

Polkadot

Polkadot is a heterogeneous blockchain protocol that connects multiple specialised blockchains into one unified network. It achieves scalability through a sharding infrastructure with multiple blockchains running in parallel, called parachains, that connect to a central chain called the Relay Chain. Developers can easily build custom application specific parachains through the Substrate development framework.
The relay chain validates the state transition of connected parachains, providing shared state across the entire ecosystem. If the Relay Chain must revert for any reason, then all of the parachains would also revert. This is to ensure that the validity of the entire system can persist, and no individual part is corruptible. The shared state makes it so that the trust assumptions when using parachains are only those of the Relay Chain validator set, and no other. Interoperability is enabled between parachains through Cross-Chain Message Passing (XCMP) protocol and is also possible to connect to other systems through bridges, which are specifically designed parachains or parathreads that each are custom made to interact with another ecosystem such as Ethereum and Bitcoin. The hope is to have 100 parachains connect to the relay chain.

Avalanche

Avalanche is a platform of platforms, ultimately consisting of thousands of subnets to form a heterogeneous interoperable network of many blockchains, that takes advantage of the revolutionary Avalanche Consensus protocols to provide a secure, globally distributed, interoperable and trustless framework offering unprecedented decentralisation whilst being able to comply with regulatory requirements.
Avalanche allows anyone to create their own tailor-made application specific blockchains, supporting multiple custom virtual machines such as EVM and WASM and written in popular languages like Go (with others coming in the future) rather than lightly used, poorly-understood languages like Solidity. This virtual machine can then be deployed on a custom blockchain network, called a subnet, which consist of a dynamic set of validators working together to achieve consensus on the state of a set of many blockchains where complex rulesets can be configured to meet regulatory compliance.
Avalanche was built with serving financial markets in mind. It has native support for easily creating and trading digital smart assets with complex custom rule sets that define how the asset is handled and traded to ensure regulatory compliance can be met. Interoperability is enabled between blockchains within a subnet as well as between subnets. Like Cosmos and Polkadot, Avalanche is also able to connect to other systems through bridges, through custom virtual machines made to interact with another ecosystem such as Ethereum and Bitcoin.

Comparison between Cosmos, Polkadot and Avalanche

A frequent question I see being asked is how Cosmos, Polkadot and Avalanche compare? Whilst there are similarities there are also a lot of differences. This article is not intended to be an extensive in-depth list, but rather an overview based on some of the criteria that I feel are most important. For a more in-depth view I recommend reading the articles for each of the projects linked above and coming to your own conclusions. I want to stress that it’s not a case of one platform being the killer of all other platforms, far from it. There won’t be one platform to rule them all, and too often the tribalism has plagued this space. Blockchains are going to completely revolutionise most industries and have a profound effect on the world we know today. It’s still very early in this space with most adoption limited to speculation and trading mainly due to the limitations of Blockchain and current iteration of Ethereum, which all three of these platforms hope to address. For those who just want a quick summary see the image at the bottom of the article. With that said let’s have a look

Scalability

Cosmos

Each Zone and Hub in Cosmos is capable of up to around 1000 transactions per second with bandwidth being the bottleneck in consensus. Cosmos aims to have thousands of Zones and Hubs all connected through IBC. There is no limit on the number of Zones / Hubs that can be created

Polkadot

Parachains in Polkadot are also capable of up to around 1500 transactions per second. A portion of the parachain slots on the Relay Chain will be designated as part of the parathread pool, the performance of a parachain is split between many parathreads offering lower performance and compete amongst themselves in a per-block auction to have their transactions included in the next relay chain block. The number of parachains is limited by the number of validators on the relay chain, they hope to be able to achieve 100 parachains.

Avalanche

Avalanche is capable of around 4500 transactions per second per subnet, this is based on modest hardware requirements to ensure maximum decentralisation of just 2 CPU cores and 4 GB of Memory and with a validator size of over 2,000 nodes. Performance is CPU-bound and if higher performance is required then more specialised subnets can be created with higher minimum requirements to be able to achieve 10,000 tps+ in a subnet. Avalanche aims to have thousands of subnets (each with multiple virtual machines / blockchains) all interoperable with each other. There is no limit on the number of Subnets that can be created.

Results

All three platforms offer vastly superior performance to the likes of Bitcoin and Ethereum 1.0. Avalanche with its higher transactions per second, no limit on the number of subnets / blockchains that can be created and the consensus can scale to potentially millions of validators all participating in consensus scores ✅✅✅. Polkadot claims to offer more tps than cosmos, but is limited to the number of parachains (around 100) whereas with Cosmos there is no limit on the number of hubs / zones that can be created. Cosmos is limited to a fairly small validator size of around 200 before performance degrades whereas Polkadot hopes to be able to reach 1000 validators in the relay chain (albeit only a small number of validators are assigned to each parachain). Thus Cosmos and Polkadot scores ✅✅

Decentralisation

Cosmos

Tendermint consensus is limited to around 200 validators before performance starts to degrade. Whilst there is the Cosmos Hub it is one of many hubs in the network and there is no central hub or limit on the number of zones / hubs that can be created.

Polkadot

Polkadot has 1000 validators in the relay chain and these are split up into a small number that validate each parachain (minimum of 14). The relay chain is a central point of failure as all parachains connect to it and the number of parachains is limited depending on the number of validators (they hope to achieve 100 parachains). Due to the limited number of parachain slots available, significant sums of DOT will need to be purchased to win an auction to lease the slot for up to 24 months at a time. Thus likely to lead to only those with enough funds to secure a parachain slot. Parathreads are however an alternative for those that require less and more varied performance for those that can’t secure a parachain slot.

Avalanche

Avalanche consensus scan scale to tens of thousands of validators, even potentially millions of validators all participating in consensus through repeated sub-sampling. The more validators, the faster the network becomes as the load is split between them. There are modest hardware requirements so anyone can run a node and there is no limit on the number of subnets / virtual machines that can be created.

Results

Avalanche offers unparalleled decentralisation using its revolutionary consensus protocols that can scale to millions of validators all participating in consensus at the same time. There is no limit to the number of subnets and virtual machines that can be created, and they can be created by anyone for a small fee, it scores ✅✅✅. Cosmos is limited to 200 validators but no limit on the number of zones / hubs that can be created, which anyone can create and scores ✅✅. Polkadot hopes to accommodate 1000 validators in the relay chain (albeit these are split amongst each of the parachains). The number of parachains is limited and maybe cost prohibitive for many and the relay chain is a ultimately a single point of failure. Whilst definitely not saying it’s centralised and it is more decentralised than many others, just in comparison between the three, it scores ✅

Latency

Cosmos

Tendermint consensus used in Cosmos reaches finality within 6 seconds. Cosmos consists of many Zones and Hubs that connect to each other. Communication between 2 zones could pass through many hubs along the way, thus also can contribute to latency times depending on the path taken as explained in part two of the articles on Cosmos. It doesn’t need to wait for an extended period of time with risk of rollbacks.

Polkadot

Polkadot provides a Hybrid consensus protocol consisting of Block producing protocol, BABE, and then a finality gadget called GRANDPA that works to agree on a chain, out of many possible forks, by following some simpler fork choice rule. Rather than voting on every block, instead it reaches agreements on chains. As soon as more than 2/3 of validators attest to a chain containing a certain block, all blocks leading up to that one are finalized at once.
If an invalid block is detected after it has been finalised then the relay chain would need to be reverted along with every parachain. This is particularly important when connecting to external blockchains as those don’t share the state of the relay chain and thus can’t be rolled back. The longer the time period, the more secure the network is, as there is more time for additional checks to be performed and reported but at the expense of finality. Finality is reached within 60 seconds between parachains but for external ecosystems like Ethereum their state obviously can’t be rolled back like a parachain and so finality will need to be much longer (60 minutes was suggested in the whitepaper) and discussed in more detail in part three

Avalanche

Avalanche consensus achieves finality within 3 seconds, with most happening sub 1 second, immutable and completely irreversible. Any subnet can connect directly to another without having to go through multiple hops and any VM can talk to another VM within the same subnet as well as external subnets. It doesn’t need to wait for an extended period of time with risk of rollbacks.

Results

With regards to performance far too much emphasis is just put on tps as a metric, the other equally important metric, if not more important with regards to finance is latency. Throughput measures the amount of data at any given time that it can handle whereas latency is the amount of time it takes to perform an action. It’s pointless saying you can process more transactions per second than VISA when it takes 60 seconds for a transaction to complete. Low latency also greatly increases general usability and customer satisfaction, nowadays everyone expects card payments, online payments to happen instantly. Avalanche achieves the best results scoring ✅✅✅, Cosmos with comes in second with 6 second finality ✅✅ and Polkadot with 60 second finality (which may be 60 minutes for external blockchains) scores ✅

Shared Security

Cosmos

Every Zone and Hub in Cosmos has their own validator set and different trust assumptions. Cosmos are researching a shared security model where a Hub can validate the state of connected zones for a fee but not released yet. Once available this will make shared security optional rather than mandatory.

Polkadot

Shared Security is mandatory with Polkadot which uses a Shared State infrastructure between the Relay Chain and all of the connected parachains. If the Relay Chain must revert for any reason, then all of the parachains would also revert. Every parachain makes the same trust assumptions, and as such the relay chain validates state transition and enables seamless interoperability between them. In return for this benefit, they have to purchase DOT and win an auction for one of the available parachain slots.
However, parachains can’t just rely on the relay chain for their security, they will also need to implement censorship resistance measures and utilise proof of work / proof of stake for each parachain as well as discussed in part three, thus parachains can’t just rely on the security of the relay chain, they need to ensure sybil resistance mechanisms using POW and POS are implemented on the parachain as well.

Avalanche

A subnet in Avalanche consists of a dynamic set of validators working together to achieve consensus on the state of a set of many blockchains where complex rulesets can be configured to meet regulatory compliance. So unlike in Cosmos where each zone / hub has their own validators, A subnet can validate a single or many virtual machines / blockchains with a single validator set. Shared security is optional

Results

Shared security is mandatory in polkadot and a key design decision in its infrastructure. The relay chain validates the state transition of all connected parachains and thus scores ✅✅✅. Subnets in Avalanche can validate state of either a single or many virtual machines. Each subnet can have their own token and shares a validator set, where complex rulesets can be configured to meet regulatory compliance. It scores ✅ ✅. Every Zone and Hub in cosmos has their own validator set / token but research is underway to have the hub validate the state transition of connected zones, but as this is still early in the research phase scores ✅ for now.

Current Adoption

Cosmos

The Cosmos project started in 2016 with an ICO held in April 2017. There are currently around 50 projects building on the Cosmos SDK with a full list can be seen here and filtering for Cosmos SDK . Not all of the projects will necessarily connect using native cosmos sdk and IBC and some have forked parts of the Cosmos SDK and utilise the tendermint consensus such as Binance Chain but have said they will connect in the future.

Polkadot

The Polkadot project started in 2016 with an ICO held in October 2017. There are currently around 70 projects building on Substrate and a full list can be seen here and filtering for Substrate Based. Like with Cosmos not all projects built using substrate will necessarily connect to Polkadot and parachains or parathreads aren’t currently implemented in either the Live or Test network (Kusama) as of the time of this writing.

Avalanche

Avalanche in comparison started much later with Ava Labs being founded in 2018. Avalanche held it’s ICO in July 2020. Due to lot shorter time it has been in development, the number of projects confirmed are smaller with around 14 projects currently building on Avalanche. Due to the customisability of the platform though, many virtual machines can be used within a subnet making the process incredibly easy to port projects over. As an example, it will launch with the Ethereum Virtual Machine which enables byte for byte compatibility and all the tooling like Metamask, Truffle etc. will work, so projects can easily move over to benefit from the performance, decentralisation and low gas fees offered. In the future Cosmos and Substrate virtual machines could be implemented on Avalanche.

Results

Whilst it’s still early for all 3 projects (and the entire blockchain space as a whole), there is currently more projects confirmed to be building on Cosmos and Polkadot, mostly due to their longer time in development. Whilst Cosmos has fewer projects, zones are implemented compared to Polkadot which doesn’t currently have parachains. IBC to connect zones and hubs together is due to launch Q2 2021, thus both score ✅✅✅. Avalanche has been in development for a lot shorter time period, but is launching with an impressive feature set right from the start with ability to create subnets, VMs, assets, NFTs, permissioned and permissionless blockchains, cross chain atomic swaps within a subnet, smart contracts, bridge to Ethereum etc. Applications can easily port over from other platforms and use all the existing tooling such as Metamask / Truffle etc but benefit from the performance, decentralisation and low gas fees offered. Currently though just based on the number of projects in comparison it scores ✅.

Enterprise Adoption

Cosmos

Cosmos enables permissioned and permissionless zones which can connect to each other with the ability to have full control over who validates the blockchain. For permissionless zones each zone / hub can have their own token and they are in control who validates.

Polkadot

With polkadot the state transition is performed by a small randomly selected assigned group of validators from the relay chain plus with the possibility that state is rolled back if an invalid transaction of any of the other parachains is found. This may pose a problem for enterprises that need complete control over who performs validation for regulatory reasons. In addition due to the limited number of parachain slots available Enterprises would have to acquire and lock up large amounts of a highly volatile asset (DOT) and have the possibility that they are outbid in future auctions and find they no longer can have their parachain validated and parathreads don’t provide the guaranteed performance requirements for the application to function.

Avalanche

Avalanche enables permissioned and permissionless subnets and complex rulesets can be configured to meet regulatory compliance. For example a subnet can be created where its mandatory that all validators are from a certain legal jurisdiction, or they hold a specific license and regulated by the SEC etc. Subnets are also able to scale to tens of thousands of validators, and even potentially millions of nodes, all participating in consensus so every enterprise can run their own node rather than only a small amount. Enterprises don’t have to hold large amounts of a highly volatile asset, but instead pay a fee in AVAX for the creation of the subnets and blockchains which is burnt.

Results

Avalanche provides the customisability to run private permissioned blockchains as well as permissionless where the enterprise is in control over who validates the blockchain, with the ability to use complex rulesets to meet regulatory compliance, thus scores ✅✅✅. Cosmos is also able to run permissioned and permissionless zones / hubs so enterprises have full control over who validates a blockchain and scores ✅✅. Polkadot requires locking up large amounts of a highly volatile asset with the possibility of being outbid by competitors and being unable to run the application if the guaranteed performance is required and having to migrate away. The relay chain validates the state transition and can roll back the parachain should an invalid block be detected on another parachain, thus scores ✅.

Interoperability

Cosmos

Cosmos will connect Hubs and Zones together through its IBC protocol (due to release in Q1 2020). Connecting to blockchains outside of the Cosmos ecosystem would either require the connected blockchain to fork their code to implement IBC or more likely a custom “Peg Zone” will be created specific to work with a particular blockchain it’s trying to bridge to such as Ethereum etc. Each Zone and Hub has different trust levels and connectivity between 2 zones can have different trust depending on which path it takes (this is discussed more in this article). Finality time is low at 6 seconds, but depending on the number of hops, this can increase significantly.

Polkadot

Polkadot’s shared state means each parachain that connects shares the same trust assumptions, of the relay chain validators and that if one blockchain needs to be reverted, all of them will need to be reverted. Interoperability is enabled between parachains through Cross-Chain Message Passing (XCMP) protocol and is also possible to connect to other systems through bridges, which are specifically designed parachains or parathreads that each are custom made to interact with another ecosystem such as Ethereum and Bitcoin. Finality time between parachains is around 60 seconds, but longer will be needed (initial figures of 60 minutes in the whitepaper) for connecting to external blockchains. Thus limiting the appeal of connecting two external ecosystems together through Polkadot. Polkadot is also limited in the number of Parachain slots available, thus limiting the amount of blockchains that can be bridged. Parathreads could be used for lower performance bridges, but the speed of future blockchains is only going to increase.

Avalanche

A subnet can validate multiple virtual machines / blockchains and all blockchains within a subnet share the same trust assumptions / validator set, enabling cross chain interoperability. Interoperability is also possible between any other subnet, with the hope Avalanche will consist of thousands of subnets. Each subnet may have a different trust level, but as the primary network consists of all validators then this can be used as a source of trust if required. As Avalanche supports many virtual machines, bridges to other ecosystems are created by running the connected virtual machine. There will be an Ethereum bridge using the EVM shortly after mainnet. Finality time is much faster at sub 3 seconds (with most happening under 1 second) with no chance of rolling back so more appealing when connecting to external blockchains.

Results

All 3 systems are able to perform interoperability within their ecosystem and transfer assets as well as data, as well as use bridges to connect to external blockchains. Cosmos has different trust levels between its zones and hubs and can create issues depending on which path it takes and additional latency added. Polkadot provides the same trust assumptions for all connected parachains but has long finality and limited number of parachain slots available. Avalanche provides the same trust assumptions for all blockchains within a subnet, and different trust levels between subnets. However due to the primary network consisting of all validators it can be used for trust. Avalanche also has a much faster finality time with no limitation on the number of blockchains / subnets / bridges that can be created. Overall all three blockchains excel with interoperability within their ecosystem and each score ✅✅.

Tokenomics

Cosmos

The ATOM token is the native token for the Cosmos Hub. It is commonly mistaken by people that think it’s the token used throughout the cosmos ecosystem, whereas it’s just used for one of many hubs in Cosmos, each with their own token. Currently ATOM has little utility as IBC isn’t released and has no connections to other zones / hubs. Once IBC is released zones may prefer to connect to a different hub instead and so ATOM is not used. ATOM isn’t a fixed capped supply token and supply will continuously increase with a yearly inflation of around 10% depending on the % staked. The current market cap for ATOM as of the time of this writing is $1 Billion with 203 million circulating supply. Rewards can be earnt through staking to offset the dilution caused by inflation. Delegators can also get slashed and lose a portion of their ATOM should the validator misbehave.

Polkadot

Polkadot’s native token is DOT and it’s used to secure the Relay Chain. Each parachain needs to acquire sufficient DOT to win an auction on an available parachain lease period of up to 24 months at a time. Parathreads have a fixed fee for registration that would realistically be much lower than the cost of acquiring a parachain slot and compete with other parathreads in a per-block auction to have their transactions included in the next relay chain block. DOT isn’t a fixed capped supply token and supply will continuously increase with a yearly inflation of around 10% depending on the % staked. The current market cap for DOT as of the time of this writing is $4.4 Billion with 852 million circulating supply. Delegators can also get slashed and lose their DOT (potentially 100% of their DOT for serious attacks) should the validator misbehave.

Avalanche

AVAX is the native token for the primary network in Avalanche. Every validator of any subnet also has to validate the primary network and stake a minimum of 2000 AVAX. There is no limit to the number of validators like other consensus methods then this can cater for tens of thousands even potentially millions of validators. As every validator validates the primary network, this can be a source of trust for interoperability between subnets as well as connecting to other ecosystems, thus increasing amount of transaction fees of AVAX. There is no slashing in Avalanche, so there is no risk to lose your AVAX when selecting a validator, instead rewards earnt for staking can be slashed should the validator misbehave. Because Avalanche doesn’t have direct slashing, it is technically possible for someone to both stake AND deliver tokens for something like a flash loan, under the invariant that all tokens that are staked are returned, thus being able to make profit with staked tokens outside of staking itself.
There will also be a separate subnet for Athereum which is a ‘spoon,’ or friendly fork, of Ethereum, which benefits from the Avalanche consensus protocol and applications in the Ethereum ecosystem. It’s native token ATH will be airdropped to ETH holders as well as potentially AVAX holders as well. This can be done for other blockchains as well.
Transaction fees on the primary network for all 3 of the blockchains as well as subscription fees for creating a subnet and blockchain are paid in AVAX and are burnt, creating deflationary pressure. AVAX is a fixed capped supply of 720 million tokens, creating scarcity rather than an unlimited supply which continuously increase of tokens at a compounded rate each year like others. Initially there will be 360 tokens minted at Mainnet with vesting periods between 1 and 10 years, with tokens gradually unlocking each quarter. The Circulating supply is 24.5 million AVAX with tokens gradually released each quater. The current market cap of AVAX is around $100 million.

Results

Avalanche’s AVAX with its fixed capped supply, deflationary pressure, very strong utility, potential to receive air drops and low market cap, means it scores ✅✅✅. Polkadot’s DOT also has very strong utility with the need for auctions to acquire parachain slots, but has no deflationary mechanisms, no fixed capped supply and already valued at $3.8 billion, therefore scores ✅✅. Cosmos’s ATOM token is only for the Cosmos Hub, of which there will be many hubs in the ecosystem and has very little utility currently. (this may improve once IBC is released and if Cosmos hub actually becomes the hub that people want to connect to and not something like Binance instead. There is no fixed capped supply and currently valued at $1.1 Billion, so scores ✅.

All three are excellent projects and have similarities as well as many differences. Just to reiterate this article is not intended to be an extensive in-depth list, but rather an overview based on some of the criteria that I feel are most important. For a more in-depth view I recommend reading the articles for each of the projects linked above and coming to your own conclusions, you may have different criteria which is important to you, and score them differently. There won’t be one platform to rule them all however, with some uses cases better suited to one platform over another, and it’s not a zero-sum game. Blockchain is going to completely revolutionize industries and the Internet itself. The more projects researching and delivering breakthrough technology the better, each learning from each other and pushing each other to reach that goal earlier. The current market is a tiny speck of what’s in store in terms of value and adoption and it’s going to be exciting to watch it unfold.

Overview

Cosmos

Cosmos is a heterogeneous network of many independent parallel blockchains, each powered by classical BFT consensus algorithms like Tendermint. Developers can easily build custom application specific blockchains, called Zones, through the Cosmos SDK framework. These Zones connect to Hubs, which are specifically designed to connect zones together.
The vision of Cosmos is to have thousands of Zones and Hubs that are Interoperable through the Inter-Blockchain Communication Protocol (IBC). Cosmos can also connect to other systems through peg zones, which are specifically designed zones that each are custom made to interact with another ecosystem such as Ethereum and Bitcoin. Cosmos does not use Sharding with each Zone and Hub being sovereign with their own validator set.
For a more in-depth look at Cosmos and provide more reference to points made in this article, please see my three part series — Part One, Part Two, Part Three
https://youtu.be/Eb8xkDi_PUg

Polkadot

Polkadot is a heterogeneous blockchain protocol that connects multiple specialised blockchains into one unified network. It achieves scalability through a sharding infrastructure with multiple blockchains running in parallel, called parachains, that connect to a central chain called the Relay Chain. Developers can easily build custom application specific parachains through the Substrate development framework.
The relay chain validates the state transition of connected parachains, providing shared state across the entire ecosystem. If the Relay Chain must revert for any reason, then all of the parachains would also revert. This is to ensure that the validity of the entire system can persist, and no individual part is corruptible. The shared state makes it so that the trust assumptions when using parachains are only those of the Relay Chain validator set, and no other. Interoperability is enabled between parachains through Cross-Chain Message Passing (XCMP) protocol and is also possible to connect to other systems through bridges, which are specifically designed parachains or parathreads that each are custom made to interact with another ecosystem such as Ethereum and Bitcoin. The hope is to have 100 parachains connect to the relay chain.

Avalanche

Avalanche is a platform of platforms, ultimately consisting of thousands of subnets to form a heterogeneous interoperable network of many blockchains, that takes advantage of the revolutionary Avalanche Consensus protocols to provide a secure, globally distributed, interoperable and trustless framework offering unprecedented decentralisation whilst being able to comply with regulatory requirements.
Avalanche allows anyone to create their own tailor-made application specific blockchains, supporting multiple custom virtual machines such as EVM and WASM and written in popular languages like Go (with others coming in the future) rather than lightly used, poorly-understood languages like Solidity. This virtual machine can then be deployed on a custom blockchain network, called a subnet, which consist of a dynamic set of validators working together to achieve consensus on the state of a set of many blockchains where complex rulesets can be configured to meet regulatory compliance.
Avalanche was built with serving financial markets in mind. It has native support for easily creating and trading digital smart assets with complex custom rule sets that define how the asset is handled and traded to ensure regulatory compliance can be met. Interoperability is enabled between blockchains within a subnet as well as between subnets. Like Cosmos and Polkadot, Avalanche is also able to connect to other systems through bridges, through custom virtual machines made to interact with another ecosystem such as Ethereum and Bitcoin.

Comparison between Cosmos, Polkadot and Avalanche

A frequent question I see being asked is how Cosmos, Polkadot and Avalanche compare? Whilst there are similarities there are also a lot of differences. This article is not intended to be an extensive in-depth list, but rather an overview based on some of the criteria that I feel are most important. For a more in-depth view I recommend reading the articles for each of the projects linked above and coming to your own conclusions. I want to stress that it’s not a case of one platform being the killer of all other platforms, far from it. There won’t be one platform to rule them all, and too often the tribalism has plagued this space. Blockchains are going to completely revolutionise most industries and have a profound effect on the world we know today. It’s still very early in this space with most adoption limited to speculation and trading mainly due to the limitations of Blockchain and current iteration of Ethereum, which all three of these platforms hope to address. For those who just want a quick summary see the image at the bottom of the article. With that said let’s have a look

Scalability

Cosmos

Each Zone and Hub in Cosmos is capable of up to around 1000 transactions per second with bandwidth being the bottleneck in consensus. Cosmos aims to have thousands of Zones and Hubs all connected through IBC. There is no limit on the number of Zones / Hubs that can be created

Polkadot

Parachains in Polkadot are also capable of up to around 1500 transactions per second. A portion of the parachain slots on the Relay Chain will be designated as part of the parathread pool, the performance of a parachain is split between many parathreads offering lower performance and compete amongst themselves in a per-block auction to have their transactions included in the next relay chain block. The number of parachains is limited by the number of validators on the relay chain, they hope to be able to achieve 100 parachains.

Avalanche

Avalanche is capable of around 4500 transactions per second per subnet, this is based on modest hardware requirements to ensure maximum decentralisation of just 2 CPU cores and 4 GB of Memory and with a validator size of over 2,000 nodes. Performance is CPU-bound and if higher performance is required then more specialised subnets can be created with higher minimum requirements to be able to achieve 10,000 tps+ in a subnet. Avalanche aims to have thousands of subnets (each with multiple virtual machines / blockchains) all interoperable with each other. There is no limit on the number of Subnets that can be created.

Results

All three platforms offer vastly superior performance to the likes of Bitcoin and Ethereum 1.0. Avalanche with its higher transactions per second, no limit on the number of subnets / blockchains that can be created and the consensus can scale to potentially millions of validators all participating in consensus scores ✅✅✅. Polkadot claims to offer more tps than cosmos, but is limited to the number of parachains (around 100) whereas with Cosmos there is no limit on the number of hubs / zones that can be created. Cosmos is limited to a fairly small validator size of around 200 before performance degrades whereas Polkadot hopes to be able to reach 1000 validators in the relay chain (albeit only a small number of validators are assigned to each parachain). Thus Cosmos and Polkadot scores ✅✅

Decentralisation

Cosmos

Tendermint consensus is limited to around 200 validators before performance starts to degrade. Whilst there is the Cosmos Hub it is one of many hubs in the network and there is no central hub or limit on the number of zones / hubs that can be created.

Polkadot

Polkadot has 1000 validators in the relay chain and these are split up into a small number that validate each parachain (minimum of 14). The relay chain is a central point of failure as all parachains connect to it and the number of parachains is limited depending on the number of validators (they hope to achieve 100 parachains). Due to the limited number of parachain slots available, significant sums of DOT will need to be purchased to win an auction to lease the slot for up to 24 months at a time. Thus likely to lead to only those with enough funds to secure a parachain slot. Parathreads are however an alternative for those that require less and more varied performance for those that can’t secure a parachain slot.

Avalanche

Avalanche consensus scan scale to tens of thousands of validators, even potentially millions of validators all participating in consensus through repeated sub-sampling. The more validators, the faster the network becomes as the load is split between them. There are modest hardware requirements so anyone can run a node and there is no limit on the number of subnets / virtual machines that can be created.

Results

Avalanche offers unparalleled decentralisation using its revolutionary consensus protocols that can scale to millions of validators all participating in consensus at the same time. There is no limit to the number of subnets and virtual machines that can be created, and they can be created by anyone for a small fee, it scores ✅✅✅. Cosmos is limited to 200 validators but no limit on the number of zones / hubs that can be created, which anyone can create and scores ✅✅. Polkadot hopes to accommodate 1000 validators in the relay chain (albeit these are split amongst each of the parachains). The number of parachains is limited and maybe cost prohibitive for many and the relay chain is a ultimately a single point of failure. Whilst definitely not saying it’s centralised and it is more decentralised than many others, just in comparison between the three, it scores ✅
https://preview.redd.it/lv2h7g9sdhq51.png?width=1000&format=png&auto=webp&s=56eada6e8c72dbb4406d7c5377ad15608bcc730e

Latency

Cosmos

Tendermint consensus used in Cosmos reaches finality within 6 seconds. Cosmos consists of many Zones and Hubs that connect to each other. Communication between 2 zones could pass through many hubs along the way, thus also can contribute to latency times depending on the path taken as explained in part two of the articles on Cosmos. It doesn’t need to wait for an extended period of time with risk of rollbacks.

Polkadot

Polkadot provides a Hybrid consensus protocol consisting of Block producing protocol, BABE, and then a finality gadget called GRANDPA that works to agree on a chain, out of many possible forks, by following some simpler fork choice rule. Rather than voting on every block, instead it reaches agreements on chains. As soon as more than 2/3 of validators attest to a chain containing a certain block, all blocks leading up to that one are finalized at once.
If an invalid block is detected after it has been finalised then the relay chain would need to be reverted along with every parachain. This is particularly important when connecting to external blockchains as those don’t share the state of the relay chain and thus can’t be rolled back. The longer the time period, the more secure the network is, as there is more time for additional checks to be performed and reported but at the expense of finality. Finality is reached within 60 seconds between parachains but for external ecosystems like Ethereum their state obviously can’t be rolled back like a parachain and so finality will need to be much longer (60 minutes was suggested in the whitepaper) and discussed in more detail in part three

Avalanche

Avalanche consensus achieves finality within 3 seconds, with most happening sub 1 second, immutable and completely irreversible. Any subnet can connect directly to another without having to go through multiple hops and any VM can talk to another VM within the same subnet as well as external subnets. It doesn’t need to wait for an extended period of time with risk of rollbacks.

Results

With regards to performance far too much emphasis is just put on tps as a metric, the other equally important metric, if not more important with regards to finance is latency. Throughput measures the amount of data at any given time that it can handle whereas latency is the amount of time it takes to perform an action. It’s pointless saying you can process more transactions per second than VISA when it takes 60 seconds for a transaction to complete. Low latency also greatly increases general usability and customer satisfaction, nowadays everyone expects card payments, online payments to happen instantly. Avalanche achieves the best results scoring ✅✅✅, Cosmos with comes in second with 6 second finality ✅✅ and Polkadot with 60 second finality (which may be 60 minutes for external blockchains) scores ✅

Shared Security

Cosmos

Every Zone and Hub in Cosmos has their own validator set and different trust assumptions. Cosmos are researching a shared security model where a Hub can validate the state of connected zones for a fee but not released yet. Once available this will make shared security optional rather than mandatory.

Polkadot

Shared Security is mandatory with Polkadot which uses a Shared State infrastructure between the Relay Chain and all of the connected parachains. If the Relay Chain must revert for any reason, then all of the parachains would also revert. Every parachain makes the same trust assumptions, and as such the relay chain validates state transition and enables seamless interoperability between them. In return for this benefit, they have to purchase DOT and win an auction for one of the available parachain slots.
However, parachains can’t just rely on the relay chain for their security, they will also need to implement censorship resistance measures and utilise proof of work / proof of stake for each parachain as well as discussed in part three, thus parachains can’t just rely on the security of the relay chain, they need to ensure sybil resistance mechanisms using POW and POS are implemented on the parachain as well.

Avalanche

A subnet in Avalanche consists of a dynamic set of validators working together to achieve consensus on the state of a set of many blockchains where complex rulesets can be configured to meet regulatory compliance. So unlike in Cosmos where each zone / hub has their own validators, A subnet can validate a single or many virtual machines / blockchains with a single validator set. Shared security is optional

Results

Shared security is mandatory in polkadot and a key design decision in its infrastructure. The relay chain validates the state transition of all connected parachains and thus scores ✅✅✅. Subnets in Avalanche can validate state of either a single or many virtual machines. Each subnet can have their own token and shares a validator set, where complex rulesets can be configured to meet regulatory compliance. It scores ✅ ✅. Every Zone and Hub in cosmos has their own validator set / token but research is underway to have the hub validate the state transition of connected zones, but as this is still early in the research phase scores ✅ for now.

Current Adoption

Cosmos

The Cosmos project started in 2016 with an ICO held in April 2017. There are currently around 50 projects building on the Cosmos SDK with a full list can be seen here and filtering for Cosmos SDK . Not all of the projects will necessarily connect using native cosmos sdk and IBC and some have forked parts of the Cosmos SDK and utilise the tendermint consensus such as Binance Chain but have said they will connect in the future.

Polkadot

The Polkadot project started in 2016 with an ICO held in October 2017. There are currently around 70 projects building on Substrate and a full list can be seen here and filtering for Substrate Based. Like with Cosmos not all projects built using substrate will necessarily connect to Polkadot and parachains or parathreads aren’t currently implemented in either the Live or Test network (Kusama) as of the time of this writing.

Avalanche

Avalanche in comparison started much later with Ava Labs being founded in 2018. Avalanche held it’s ICO in July 2020. Due to lot shorter time it has been in development, the number of projects confirmed are smaller with around 14 projects currently building on Avalanche. Due to the customisability of the platform though, many virtual machines can be used within a subnet making the process incredibly easy to port projects over. As an example, it will launch with the Ethereum Virtual Machine which enables byte for byte compatibility and all the tooling like Metamask, Truffle etc. will work, so projects can easily move over to benefit from the performance, decentralisation and low gas fees offered. In the future Cosmos and Substrate virtual machines could be implemented on Avalanche.

Results

Whilst it’s still early for all 3 projects (and the entire blockchain space as a whole), there is currently more projects confirmed to be building on Cosmos and Polkadot, mostly due to their longer time in development. Whilst Cosmos has fewer projects, zones are implemented compared to Polkadot which doesn’t currently have parachains. IBC to connect zones and hubs together is due to launch Q2 2021, thus both score ✅✅✅. Avalanche has been in development for a lot shorter time period, but is launching with an impressive feature set right from the start with ability to create subnets, VMs, assets, NFTs, permissioned and permissionless blockchains, cross chain atomic swaps within a subnet, smart contracts, bridge to Ethereum etc. Applications can easily port over from other platforms and use all the existing tooling such as Metamask / Truffle etc but benefit from the performance, decentralisation and low gas fees offered. Currently though just based on the number of projects in comparison it scores ✅.

Enterprise Adoption

Cosmos

Cosmos enables permissioned and permissionless zones which can connect to each other with the ability to have full control over who validates the blockchain. For permissionless zones each zone / hub can have their own token and they are in control who validates.

Polkadot

With polkadot the state transition is performed by a small randomly selected assigned group of validators from the relay chain plus with the possibility that state is rolled back if an invalid transaction of any of the other parachains is found. This may pose a problem for enterprises that need complete control over who performs validation for regulatory reasons. In addition due to the limited number of parachain slots available Enterprises would have to acquire and lock up large amounts of a highly volatile asset (DOT) and have the possibility that they are outbid in future auctions and find they no longer can have their parachain validated and parathreads don’t provide the guaranteed performance requirements for the application to function.

Avalanche

Avalanche enables permissioned and permissionless subnets and complex rulesets can be configured to meet regulatory compliance. For example a subnet can be created where its mandatory that all validators are from a certain legal jurisdiction, or they hold a specific license and regulated by the SEC etc. Subnets are also able to scale to tens of thousands of validators, and even potentially millions of nodes, all participating in consensus so every enterprise can run their own node rather than only a small amount. Enterprises don’t have to hold large amounts of a highly volatile asset, but instead pay a fee in AVAX for the creation of the subnets and blockchains which is burnt.

Results

Avalanche provides the customisability to run private permissioned blockchains as well as permissionless where the enterprise is in control over who validates the blockchain, with the ability to use complex rulesets to meet regulatory compliance, thus scores ✅✅✅. Cosmos is also able to run permissioned and permissionless zones / hubs so enterprises have full control over who validates a blockchain and scores ✅✅. Polkadot requires locking up large amounts of a highly volatile asset with the possibility of being outbid by competitors and being unable to run the application if the guaranteed performance is required and having to migrate away. The relay chain validates the state transition and can roll back the parachain should an invalid block be detected on another parachain, thus scores ✅.
https://preview.redd.it/7phaylb1ehq51.png?width=1000&format=png&auto=webp&s=d86d2ec49de456403edbaf27009ed0e25609fbff

Interoperability

Cosmos

Cosmos will connect Hubs and Zones together through its IBC protocol (due to release in Q1 2020). Connecting to blockchains outside of the Cosmos ecosystem would either require the connected blockchain to fork their code to implement IBC or more likely a custom “Peg Zone” will be created specific to work with a particular blockchain it’s trying to bridge to such as Ethereum etc. Each Zone and Hub has different trust levels and connectivity between 2 zones can have different trust depending on which path it takes (this is discussed more in this article). Finality time is low at 6 seconds, but depending on the number of hops, this can increase significantly.

Polkadot

Polkadot’s shared state means each parachain that connects shares the same trust assumptions, of the relay chain validators and that if one blockchain needs to be reverted, all of them will need to be reverted. Interoperability is enabled between parachains through Cross-Chain Message Passing (XCMP) protocol and is also possible to connect to other systems through bridges, which are specifically designed parachains or parathreads that each are custom made to interact with another ecosystem such as Ethereum and Bitcoin. Finality time between parachains is around 60 seconds, but longer will be needed (initial figures of 60 minutes in the whitepaper) for connecting to external blockchains. Thus limiting the appeal of connecting two external ecosystems together through Polkadot. Polkadot is also limited in the number of Parachain slots available, thus limiting the amount of blockchains that can be bridged. Parathreads could be used for lower performance bridges, but the speed of future blockchains is only going to increase.

Avalanche

A subnet can validate multiple virtual machines / blockchains and all blockchains within a subnet share the same trust assumptions / validator set, enabling cross chain interoperability. Interoperability is also possible between any other subnet, with the hope Avalanche will consist of thousands of subnets. Each subnet may have a different trust level, but as the primary network consists of all validators then this can be used as a source of trust if required. As Avalanche supports many virtual machines, bridges to other ecosystems are created by running the connected virtual machine. There will be an Ethereum bridge using the EVM shortly after mainnet. Finality time is much faster at sub 3 seconds (with most happening under 1 second) with no chance of rolling back so more appealing when connecting to external blockchains.

Results

All 3 systems are able to perform interoperability within their ecosystem and transfer assets as well as data, as well as use bridges to connect to external blockchains. Cosmos has different trust levels between its zones and hubs and can create issues depending on which path it takes and additional latency added. Polkadot provides the same trust assumptions for all connected parachains but has long finality and limited number of parachain slots available. Avalanche provides the same trust assumptions for all blockchains within a subnet, and different trust levels between subnets. However due to the primary network consisting of all validators it can be used for trust. Avalanche also has a much faster finality time with no limitation on the number of blockchains / subnets / bridges that can be created. Overall all three blockchains excel with interoperability within their ecosystem and each score ✅✅.

Tokenomics

Cosmos

The ATOM token is the native token for the Cosmos Hub. It is commonly mistaken by people that think it’s the token used throughout the cosmos ecosystem, whereas it’s just used for one of many hubs in Cosmos, each with their own token. Currently ATOM has little utility as IBC isn’t released and has no connections to other zones / hubs. Once IBC is released zones may prefer to connect to a different hub instead and so ATOM is not used. ATOM isn’t a fixed capped supply token and supply will continuously increase with a yearly inflation of around 10% depending on the % staked. The current market cap for ATOM as of the time of this writing is $1 Billion with 203 million circulating supply. Rewards can be earnt through staking to offset the dilution caused by inflation. Delegators can also get slashed and lose a portion of their ATOM should the validator misbehave.

Polkadot

Polkadot’s native token is DOT and it’s used to secure the Relay Chain. Each parachain needs to acquire sufficient DOT to win an auction on an available parachain lease period of up to 24 months at a time. Parathreads have a fixed fee for registration that would realistically be much lower than the cost of acquiring a parachain slot and compete with other parathreads in a per-block auction to have their transactions included in the next relay chain block. DOT isn’t a fixed capped supply token and supply will continuously increase with a yearly inflation of around 10% depending on the % staked. The current market cap for DOT as of the time of this writing is $4.4 Billion with 852 million circulating supply. Delegators can also get slashed and lose their DOT (potentially 100% of their DOT for serious attacks) should the validator misbehave.

Avalanche

AVAX is the native token for the primary network in Avalanche. Every validator of any subnet also has to validate the primary network and stake a minimum of 2000 AVAX. There is no limit to the number of validators like other consensus methods then this can cater for tens of thousands even potentially millions of validators. As every validator validates the primary network, this can be a source of trust for interoperability between subnets as well as connecting to other ecosystems, thus increasing amount of transaction fees of AVAX. There is no slashing in Avalanche, so there is no risk to lose your AVAX when selecting a validator, instead rewards earnt for staking can be slashed should the validator misbehave. Because Avalanche doesn’t have direct slashing, it is technically possible for someone to both stake AND deliver tokens for something like a flash loan, under the invariant that all tokens that are staked are returned, thus being able to make profit with staked tokens outside of staking itself.
There will also be a separate subnet for Athereum which is a ‘spoon,’ or friendly fork, of Ethereum, which benefits from the Avalanche consensus protocol and applications in the Ethereum ecosystem. It’s native token ATH will be airdropped to ETH holders as well as potentially AVAX holders as well. This can be done for other blockchains as well.
Transaction fees on the primary network for all 3 of the blockchains as well as subscription fees for creating a subnet and blockchain are paid in AVAX and are burnt, creating deflationary pressure. AVAX is a fixed capped supply of 720 million tokens, creating scarcity rather than an unlimited supply which continuously increase of tokens at a compounded rate each year like others. Initially there will be 360 tokens minted at Mainnet with vesting periods between 1 and 10 years, with tokens gradually unlocking each quarter. The Circulating supply is 24.5 million AVAX with tokens gradually released each quater. The current market cap of AVAX is around $100 million.

Results

Avalanche’s AVAX with its fixed capped supply, deflationary pressure, very strong utility, potential to receive air drops and low market cap, means it scores ✅✅✅. Polkadot’s DOT also has very strong utility with the need for auctions to acquire parachain slots, but has no deflationary mechanisms, no fixed capped supply and already valued at $3.8 billion, therefore scores ✅✅. Cosmos’s ATOM token is only for the Cosmos Hub, of which there will be many hubs in the ecosystem and has very little utility currently. (this may improve once IBC is released and if Cosmos hub actually becomes the hub that people want to connect to and not something like Binance instead. There is no fixed capped supply and currently valued at $1.1 Billion, so scores ✅.

All three are excellent projects and have similarities as well as many differences. Just to reiterate this article is not intended to be an extensive in-depth list, but rather an overview based on some of the criteria that I feel are most important. For a more in-depth view I recommend reading the articles for each of the projects linked above and coming to your own conclusions, you may have different criteria which is important to you, and score them differently. There won’t be one platform to rule them all however, with some uses cases better suited to one platform over another, and it’s not a zero-sum game. Blockchain is going to completely revolutionize industries and the Internet itself. The more projects researching and delivering breakthrough technology the better, each learning from each other and pushing each other to reach that goal earlier. The current market is a tiny speck of what’s in store in terms of value and adoption and it’s going to be exciting to watch it unfold.

## Other notices coming up in Q3 2019
* The Q2 token removal will take place on July 14, 2019, which will involve in total 34 billion of NPXS and NPXSXEM (22 million worth in USD) removal. In the past 365 days, we’ve removed a total of 36.1 million US dollar worth of NPXS and NPXSXEM.
Before Q2 removal, the total supply of NPXS ERC20 is 266,962,422,906.53 and NPXSXEM is 95,816,218,929. [See Q1 removal here.](/pundix/recap-of-ama-with-zac-on-july-3-and-q2-report-a23de165dd28)
* [NPXSXEM will be ported to Binance Chain from July 20](/pundix/npxsxem-will-be-on-binance-chain-c6485f17726b). * XPhone pre-order will start in late July with a new product name. Stay tuned. Check out the teaser video that we are releasing it across our communication channels. ## Q&A
## On XPOS
* **Where are we on official global location of XPOS?**
Zac: We have made a map on our official website that merchants can self report and feature their locations. It’s at [https://www.pundix.com/product\](https://www.pundix.com/product). We’ll be increasing and updating the map once we have permission form the merchants to update their locations.
* **The marketing from pundi has shifted from 100,000–700,000 xpos units by 2021 to 100,000. I understand the bear market has affected this but please share the strategy moving forward to hit your goal. How do you feel about hitting this goal?**
Zac: The 100K XPOS target has always been the initial goal and it’s stated in our whitepaper. And we are still working on achieving the goal by the end of 2021. Part of our growth strategy is to also explore the possibility to port our platform to traditional POS manufacturers to increase the adoption, which is ongoing at the moment.
* **1 year ago you sent 5000 XPOS somewhere. When, at least half of them, will be working? 3 year target was 100,000 by 2021. Now we have only 150 units, how do you expect to reach this goal?**
Zac: Yes, we have shipped thousands of XPOS to over 30 countries in the world. The 150 you’ve mentioned are the featured merchants which are published on the map. The active XPOS devices are deployed over 33 countries and we are actively talking to B2B partners to have higher wholesale and big deployments.
* **How many XPOS are live and used?**
Zac: We have gone through a very serious bear market, and some of the initial inbound requests for XPOS are not delivered. However, we are working slowly but surely with our Business Development team to not just roll-out into individual buyers, such as what we did on Pizza Day, but also to B2B partners. With the certifications approved, that will also help us to officially roll out to some of the key markets.
Individual merchants can use XWallet collection feature to accept crypto payment with QR code. For the merchants who have physical offline storefronts, they can use XPOS to enable the instant crypto transaction seamlessly. Moreover, as mentioned previously, we are exploring the integration on leading traditional POS terminal so that their distributors have option to enable crypto transaction feature. As for the challenge to adopt XPOS, it is the regulatory compliance in different countries. For this, our legal team think ahead and encourage our merchants to complete KYC.
I must be very honest to say the activation takes longer time than we expect but it will be worth at the end.
* **What’s the average number of transactions per xpos in use?**
Zac: The transaction number has increased very well. The number of each XPOS differs, due to the frequency of using crypto currency to purchase item or crypto assets. There’s no standard answer to this, but overall we see the transaction number and volume are going up.
* **How do you plan to reach the target of 100,000 by 2021?**
Zac: One of the challenges that we have is regulatory compliances in different countries. There are certain markets that do not allow crypto currencies and some require a clear approval for us to deploy XPOS. We are working on both challenges by talking to governments and applying for certifications. So how we plan to reach 100,000 XPOS user by 2021 is to work with distributors, B2B partners on a government / business level, and with existing POS companies to integrate our software solution into the system.
* **We understand as there was bear market and hence Xpos usage demand was low. Are you guys seeing growth of Xpos usage with current market conditions. Can you guys put some statistics comparison like last 30 days Xpos usage vs any month from bear market usage?**
Zac: It is very clear that as we moved out from the bear market, the demand for XPOS has been increasing. As we’ve shared just now both the transaction number and volume of Q2 have beaten Q1. We’ll be able to share more transaction numbers once we receive approval from our XPOS merchants.
One exciting thing is that, with the listing of different tokens, we also see users using these tokens as a way to transact on XPOS, which means we will be having more ways to transact and this is a growth point for XPOS.
* **When will there be more details for XPHONE and XPOS HANDY?**
Zac: For XPOS handy, we have finished production and it will be released in Q3
* **When will the iOS version of XWallet and XPOS be fully translated to other languages?**
Zac: Right now, the XWallet has Traditional Chinese, Korean, Spanish, German and English. With the latest version update, it now includes Portuguese. XPOS also comes with many languages and we hope to finish with more language, either working with professionals or volunteers. If you’re interested in volunteering, please contact us.
* **When will the Merchant back office have Product Registration and SKU id ability and also integrate with other POS software?** * **When will the top-up feature go away for XPOS to allow liquidity for XPOS**
Zac: We constantly update features in XPOS and merchant backend to make it easier for distributors and merchants to use. We understand that one of the ways for mass adoption is to enhance our distributor management system. With that, the distributors can manage manay XPOS at one time with different merchants.
Please stay tuned as we announce more and more functions of this feature.
## On Dubai
* **When will we see the deployment of the XPOS in Dubai?** * **Can we spend NPXS on the Dubai XPOS?**
Zac: As with all big projects there are a lot of moving parts, that includes working very closely with the local government, in Dubai’s case, the Credit Bureau of the Finance Ministry. Things are progressing for the Dubai project but due to confidentiality agreements with the parties involved, we cannot reveal much. All we can say is that we and our Dubai partners are working hard to have XPOS roll-out in the Dubai market and the UAE.
We are also discussing aggressively with Dubai partners whether to include crypto assets in the XPOS in Dubai. That clearly will involve local compliance and legal for that to happen.
* **Your system upgrades expect merchants to have downtime on their XPOS terminals, can you explain if you plan to run a business why this would be considered feasible (specially at the rate you have been doing your upgrades)?**
Zac: Yes, the benefit / strength of the XPOS is that most of the updates can be done on the fly. For example, when we have a token update on our XPOS where developers submit their tokens on Open Platform, the updates of this token are on the fly, which means that once we approve the token on our Open Platform, it will automatically appear on XPOS without any software updates.
The great thing that we believe about XPOS is not just the support of crypto assets, but also the ability to update most things on the fly, which means that whenever we have a good feature or a new token, the updates will be done instantaneously.
* **Can you guys arrange at least a community voting which is the next blockchain we would like to see next in XPOS? Voting will help to prioritize to chose the projects.**
Zac: One of the reasons why BNB is being listed on the XPOS is simply because of its popularity and also our user demand, in a way that we are already answering to our community’s request.
Right now, our main focus is getting all the tokens submitted on Open Platform to be listed on the XPOS. The submission process includes legal and compliance valid, so our legal and compliance teams are working hard to make sure that we have more tokens to roll out onto Open Platform, which means that they will be on XPOS, XWallet, and XPASS.
As to a specific voting mechanism, we’d like to consider that and hopefully we’ll be able to run a specific voting for the chain which users would like to see.
* **While comparing Xpos handy to Square POS devices at least with mobile it’s very cheap like under $30 and easy to use. When can we expect such light weight and cheaper version for XPOS? Is team working on such devices ?**
Zac: There are different POS companies around the globe and pour focus is to work with these POS companies with our software, so that a crypto sales feature will be part of the existing POS system. The more support of crypto asset usage using our software on existing POS, the better it is for global adoption.
We actually strongly believe that the pricing of our POS system is competitive in the market. And one of the great features of the XPOS is that the merchants will not need not to pay a certain percentage to existing acquirer but to be able to earn certain percentage from each transaction. That is the key differentiator for merchant to want to adopt this.
* **From the website with some of the key Countries for XPOS adoption looks great. However, the concern is for Venezuela, there is no reference link like the others have. Can you guys add the link with details to clear the ambiguity?**
Zac: Let’s give a little bit more patience so that we can actually release more information about our Venezuelan partnership. The good news is that we expect concrete news from Venezuela in the coming 2 weeks. So stay up-to-date about our Venezuelan roll out on XPOS, the best way is to subscribe to our telegram group for Venezuela.
## On Partnerships
* **Are there some major partnership in the works? I’m also interested in how you do immediate transactions? Do you anticipate scaling issues?**
Zac: The way XPOS is being designed is that when you use your crypto assets to purchase, it will have instantaneous confirmation because the action is an off-chain process. An on-chain action happens when a user who owns crypto assets in our system transferring the assets out of the Pundi X ecosystem to their own wallets; or to transfer crypto assets in Pundi X from an off-chain to a private wallet, which we will have very soon on XWallet itself.
That is why we are able to handle scaling. When a person wants to use crypto currency to buy a coffee, the transaction will happen instantaneously.
For specific partnership, especially with B2B partnership, we oblige to the NDA that we have signed. But if you follow us closely, you’ll know that we go to different parts of the world, talking to major companies to try to land more deals so that NPXS usage will increase dramatically.
* **Any big partnerships for making xphone or using the software for xBlockchain?**
Zac: These partnerships are also subjected to NDA, so please be patient for us to release more news.
* **When will XPOS have approval to process Visa and MasterCard payments?**
Zac: We have met representatives from these players including some of the key management people. They are obviously looking into crypto currency attentively, and we hope that there’s something we can do with MasterCard and/or Visa.
This is something that the community has suggested and we agree fully. Please allow us with some time to work on this. We have also showcased XPOS to the CEO of MasterCard. For what or when will anything happen, please wait for our official announcement.
* **What’s the status on Quantum fund and their contribution or involvement with Pundi’s project?**
Zac: We announced last year that we are creating a fund to invest in projects beneficial to our ecosystem. We’ve identified some interesting projects, and we have invested in at least 1 project. The reason why we’re investing in that project is because of the services that it will bring onto the Pindi X ecosystem. So the purpose of the investment of the companies is that these companies in turn will benefit on our ecosystem. This is our key consideration.
The team has evaluated the projects that will benefit the Pundi X / Function X ecosystem. Vic and his team will be able to reveal more details on the companies we have invested in and how they will contribute to our ecosystem in Q3.
* **Recent update on NPXSXEM is highly ambiguous as mentioned that it will be now BEP token and later once FX goes live it will get back to Fx platform. Why you guys had so rush to use Binance chain only for few months? Isn’t you guys switching to much in a short time span?**
Zac: Liquidity and utility have been an issue for NPXSXEM. Due to the design philosophy and the limit of token that can be created on NEM’s smart contract, we are only able to create a small number of tokens on NPXSXEM. By moving into the Binance chain for NPXSXEM, the BEP2 token version will be able to support all the NPXSXEM tokens, which means that we’ll migrate and also be able to make sure all the NPXSXEM tokens are under the same contract address.
We believe with the strong liquidity, we will be able to give our NPXSXEM token holders a good reason of what the token holders have been waiting for. We hope to bring NPXSXEM to match the level of NPXS.
* **When #XRP?**
Zac: Our OpenPlatform is a currency agnostic platform, which means that we will work on integrating public chain as well as tokens that are most requested by the users. We’ll also be looking into the listing of different tokens that are being mentioned by the community.
As said, we will have at least one more public chain integration in Q3, perhaps even more.
* **Are you as a company going to try and connect with libra? If they have said they want to be a payment remittance service, have Square, PayPal, Visa on board I as an investor would prefer you try to join them rather than beat such large competitors**
Zac: Of course, we’ll be delighted to work with Facebook and also the Libra coin. Pundi X and XPOS is a currency agnostic / currency neutral platform, if there’s opportunity to list Libra coin or work with Facebook in different ways to promote crypto currency adoption, we’ll certainly look into that and work on reaching out to them.
## On Trading
* **Can you confirm during AMA, Pundi team is not involved with any trading with their own token like selling over time to manage the fund to run the company.**
Zac: All the wallet addresses of the team holdings are disclosed and transparent. This is one of the first things that we did after ICO. Hence, our token holdings are transparent and everyone can monitor our fund transactions. Also, we have strict internal financial regulation and compliance, shows that we are here to build a long-term project.
The best way to make NPXS or the NPXSXEM to rise is real daily life use case.
* **When will you stop manipulating NPXS chart?**
Zac: Our focus has always been and will be building great products. The more product usage, the demands for NPXS and NPXSXEM will increase. Let’s address again that, Pundi X the company is NOT involved in any manipulation of the NPXS price.
There are trading teams, market makers, financial institutions that profit from the drop and rise of token prices in the crypto market. The good thing about NPXS is that we have managed to create a high liquidity by listing on 40+ exchanges and having global trades and demand from all over the world. We hope this and coupled with the fact that we are a solid product and roll out the use cases, the demand of NPXS will only continue to rise and will be able to deter any of the traders or speculators there is for NPXS.
These traders gain profit from manipulating tokens whether BTC or other tokens. In fact, the traditional financial markets have similar challenges as well. What I want to stress is that, we at Pundi X, do NOT speculate or manipulate the price. We work very hard to create demands for NPXS and as a company, it is only beneficial for us to see the prices of NPXS and NPXSXEM rise.
* **Can we please address the elephant in the room which is the Binance bot with huge sell walls and buy walls causing huge distress and concern among users?**
Zac: First, I cannot confirm nor deny that whether Binance has a bot. I think this is something that you need to ask Binance. We need to work with Binance because Binance has one of the biggest liquidities, if not the greatest liquidity, for NPXS. The best way to counter manipulators is to create more use case, more demand and more acceptance of our tokens.
* **Why on almost all exchanges do you not offer a USDT trading pair?**
Zac: We have USDT trading pairs on Bittrex, Bittrue, and more. In addition, we have fiat pairs in Korean Won, IDR, INR, and Turkish liras. We will continue to work on adding trading pairs for NPXS to make it more liquidate.
* **Why don’t you offer a stable coin sell and purchase on the xpos to help with adoption? Places in Africa with volatile currencies would go crazy for this.**
Zac: It’s a great observation. This is a request that’s been asked from many users. We’re working on stable coin listing on XPOS and hopefully it’ll come soon. Stable coin requires a greater compliance and legal validate, which we have been working on since months ago and we hope to have the stable coin up in XPOS soon.
* **When will you add an active tracker for coin burn, whether its measured in usd, NPXS or whatever you choose. The community has been asking for this on twitter, reddit and telegram for this entire year.**
Zac: It will be hard for us to have a daily tracker of the coin burn, but what we might be able to work on is a tracker which have shown all of the tokens that have been removed from the usage. Thank you for giving us this great suggestion and we will work on it in some form.
Zac: Our token supply has always been specified in our white paper, and as promised in our white paper, we will continue to remove tokens through usage and use cases, which we’re working on all the time.
* **Price movement. When will NPXS go to which price?**
Zac: We cannot comment on the change of the price. Our focus is on building products. We hope by doing that the NPXS value will go up. Again, there’s no way that we can comment on the price.
**I believe that burning tokens every 14 weeks keeps the price suppressed and will only lead to huge pumps and dumps. Imo, If the burns were more frequent, the price would move organically.**
Zac: We continue removing tokens quarterly per advised by our legal and compliance team.
**Is it mandatory npxs swap? What happens for token we have in binance?**
Zac: No it’s not a mandatory NPXS swap for FX.
**How many NPXS or NPXSXEM was converted?**
Zac: In Q2, we will remove 29B NPXSXEM and 9B NPXS.
## On XWallet
* **Why not put in XWallet like the place where we can buy and sell like restaurants and shops?**
Zac: You are correct. In fact, if you look at XWallet, there is a merchant feature, whereby you can register as a merchant. By becoming a merchant, you will be able to print out your QR code and stick it on your restaurant. People are able to make payment through this QR code. This will act like a mini-XPOS.
* **In addition to that having multiple different blockchain in XWallet will increase the XWallet adoption. Hence, we would like to see aggressive game plan and execution from the team and would like to hear that**
Zac: That’s a great suggestion. Every day we want to increase use cases for XWallet. In fact, our XWallet update is one of the most frequent in the market. Within 5 months, we have over 10 updates on iOS and Google Play. This does not include soft update which happens every several days. In my view, the effort is very tremendous.
* **Is there any plan to add Swap option within XWallet so that people can trade the coins within XWallet?**
Zac: Yes, there’s such plan and in fact there is an upcoming feature that people will be able to use coins in XWallet to exchange into other things. The exact form and format have not been reviewed. We hope to share more when we have concrete example. But what you suggested is what we are planning for months ago.
* **When will XPOS and XWallet have fiat on ramps?**
Zac: This is a good question. It’s not only involved with regulatory compliance but also involved the technical part. This is also something we are planning for months. Once approved, hopefully we are able to support fiat currency on ramps and off ramps on XWallet.
**On Others*\*
* **How is the internal organization doing? Currently how many employees work for Pundi? Currently how many job positions are open?**
Zac: Pundi X has grown tremendously. We are now having over seven offices around the globe. I’m sitting in the Singapore office. We have office in Jakarta, Taiwan, Tokyo, Shenzhen, São Paulo and London. These are the places we have physical offices and house approximately 100 full time employees of Pundi X.
The positions open from Pundi X are legal associate in Singapore and other offices. We are looking for more R&D people, especially in Taiwan. We are looking at marketing and PR people in different parts of the world. And we are looking for POS distributors. As a POS distributor, you will work with our business development team and also our technical team to roll out many XPOS which you have a network to control in your local market.
* **Would you consider removing the KYC to allow u.s. holder to stake and be rewarded?**
Zac: We would love to have more users, including US. However, our compliance and legal advisors have not allowed us to accept US holders to stake and be rewarded.
I’m sorry to say that but this is after serious consideration to make such a decision. In fact, it is a very hard decision because we have healthy user base in the US.
will continue to monitor the situation in the different markets and be compliant. There are also ways to be rewarded when using XWallet service without KYC. We are looking into to explore more on this and launch new features. Hopefully we are able to bring the beta version for you to test this week or next.
**On XPhone*\*
* **Where are we on pre-sale announcement of Xphone? It was highlights of Q2 goal. If we are getting delay, that’s ok. But at least community will have some clarification why it’s getting late and when approximately it coming?**
Zac: Pre-sale order will start this month. It’s likely the end of July. Pre-sale will take place in different channel including the official website and XWallet. Apart of our own channel, the pre-sale will go live on a 3rd party channel. People will be able to pre-order crypto either in crypto or in fiat.
* **Can you discuss in AMA, is participants can pay with Crypto or Credit/debit card or in both ways?**
Zac: As a crypto company, we prefer payment in crypto, but fiat, Visa, MasterCard, and other traditional payment methods will be accepted on different pre-order channels. Stay tuned for pre-order which will happen in late July.
* **Will the Xphone be open to purchase in all regions of the world?**
Zac: Yes, pre-orders will be able to be done on-line, and products will be shipped from our offices to users in different parts of the world.
* **Will the blockchain mode on the Xphone be operable during the testnet or will this function not work until mainnet?**
Zac: XWallet and XPhone are the first channel and avenue for Function X testnet, so once the testnet is operateble, we will start to engage certain services on XWallet and XPhone into Function X testnet, and ultimately into mainnet. Slowly but surely.
* **Does Xphone have hard protective cover,extra Sim slot, also is it enhanced with ip68 water rating?**
Zac: XPhone will not be waterproof, so please do not submerge XPhone into water. XPhone will definitely be eavesdrop-proof because we’re using a blockchain mode, only you and you control your own conversation.
* **Which country accept the Xphone?** * **Will I also be able to use the SIM-card?** * **The blockchain modus will work in every country (what in the absense of nodes)?** * **Will the XPhone I buy now support updates in the future?**
Zac: People from any country will be able to buy XPhone on-line. You will be able to use a SIM for we have built a SIM slot. Wherever you are, the XPhone can be turned on to become a node.
Will XPhone support future updates? Yes, of course. Just like the XPOS, we support silent update. It will be like how we support XPOS, many updates. The updates will always be supported on XPhone.
**On Function X*\*
* **When is the detail white paper coming for FunctionX? Why the team is very resistive to have well documented white paper? We need scientific approach and well documentation on FunctionX to have developers to be more involved.**
Zac: Yes, developer involvement is a key criterion of the growth of Function X. We have done 2 things, one is that we have set up Function X Foundation which is led by David Ben Kay and will involve third party adviser and board members. Second, we have set up a developer relations team led by one of our own members as well. This team will work on creating developer documents, developer demos and sample, so that excellent developers can tap into working with Function X resources.
The first version of developer documentation is ready in English and Chinese. We are still polishing up the documents and hopefully to release them soon.
We are also working with third party developers, and are engaging at least 2 third party developer companies, so that we can help create their services on Function X and also XWallet.
We are hoping to showcase a smooth and usable service to the audience, we think this is the key criterion of the Function X growth.
Thank you for this suggestion. We need to update more often on github developer documentation as well.
As for the white paper, we did not have one per se because Function X did not do an ICO. But we will continue to update our white paper and include not only technical details, but also details on the chain and how we can get more developers and users so that the future hardware will be added as a node and you will be rewarded financially, at least through our ecosystem genesis fund. Please stay tuned and there are a lot of things going on in the company. Each and one of us is working hard.
* **Why does the FX ecosystem need a decentralized OS?**
Zac: The mantra of Function X is decentralization and having private control of your data. A full private control of your data comes with a decentralized system not just in transmission of your data, but with the operating system built fully for decentralization , which includes a transmission protocol replacing http. The apps uploaded into Function X will be decentralized as well as the data that is stored on the app, which means that how BitCoin or crypto assets are verified on different nodes will also be part of the way we store data and content.
The decentralized OS is key to fulfilling a decentralized environment for a more private and free usage.
* **What about FX are you most excited about?**
Zac: We are actually creating a shift of how people view of blockchain and how decentralization is not just about transacting commercial commodity, but also data, including your identity, are all decentralized. That is what we are most excited about.
The only way for us to achieve this is to have developer support, for we need the developers to build on the foundation we have to offer those exciting services.
* **We understand that developing a new blockchain is time consuming. As a community we are in a dark space to understand where exactly the development of FX right now.**
Zac: We are working hard on creating the testnet and eventually the mainnet. For the latest updates of Function X, what I can encourage you to do is to go on and subscribe to the Function X telegram group where discussions are made. We have formed the Function X Foundation and created the developer relations team, so that the Function X progress will go smoother and with more partnership from outside, whether it’s developers, third party companies, teleco, etc.
* **When FX goes live on the mainnet, will FX coin be used to stake and earn NPXS? how will staking work on that new mainnet?**
Zac: The NPXS/NPXSXEM staking will last till March 9, 2020 as announced. What we are committed is to create more use cases. For FX tokens, the use cases will be focusing on the Function X Chain and the use cases on Function X that include DApp on Function X and different hardware/software services.
* **When fx testnet will be available?**
Zac: First I would like to thank you for your constant support. In Q3, we plan to open Function X testnet so that we will be migrating and creating certain use cases that can be used on Function X testnet, starting with our own XWallet. Which means, the XWallet will migrate some features into Function X testnet, and slowly followed by our other Pundi X products, including XPhones, XPASS, Open Platform and Function X own developer related products from third parties.

Craig Steven Wright is Satoshi Nakamoto

A couple of years ago in the early months of the 2017, I published a piece called Abundance Via Cryptocurrencies (https://www.reddit.com/C\_S\_T/comments/69d12a/abundance\_via\_cryptocurrencies/) in which I kind of foresaw the crypto boom that had bitcoin go from $1k to $21k and the alt-coin economy swell up to have more than 60% of the bitcoin market capitalisation. At the time, I spoke of coming out from “the Pit” of conspiracy research and that I was a bit suss on bitcoin’s inception story. At the time I really didn’t see the scaling solution being put forward as being satisfactory and the progress on bitcoin seemed stifled by the politics of the social consensus on an open source protocol so I was looking into alt coins that I thought could perhaps improve upon the shortcomings of bitcoin. In the thread I made someone recommended to have a look at 4chan’s business and finance board. I did end up taking a look at it just as the bull market started to really surge. I found myself in a sea of anonymous posters who threw out all kinds of info and memes about the hundreds, thousands, tens of thousands of different shitcoins and why they’re all going to have lambos on the moon. I got right in to it, I loved the idea of filtering through all the shitposts and finding the nuggest of truth amongst it all and was deeply immersed in it all as the price of bitcoin surged 20x and alt coins surged 5-10 times against bitcoin themselves. This meant there were many people who chucked in a few grand and bought a stash of alt coins that they thought were gonna be the next big thing and some people ended up with “portfolios” 100-1000x times their initial investment.
To explain what it’s like to be on an anonymous business and finance board populated with incel neets, nazis, capitalist shit posters, autistic geniuses and whoever the hell else was using the board for shilling their coins during a 100x run up is impossible. It’s hilarious, dark, absurd, exciting and ultimately addictive as fuck. You have this app called blockfolio that you check every couple of minutes to see the little green percentages and the neat graphs of your value in dollars or bitcoin over day, week, month or year. Despite my years in the pit researching conspiracy, and my being suss on bitcoin in general I wasn’t anywhere near as distrustful as I should have been of an anonymous business and finance board and although I do genuinely think there are good people out there who are sharing information with one another in good faith and feel very grateful to the anons that have taken their time to write up quality content to educate people they don’t know, I wasn’t really prepared for the level of organisation and sophistication of the efforts groups would go to to deceive in this space.
Over the course of my time in there I watched my portfolio grow to ridiculous numbers relative to what I put in but I could never really bring myself to sell at the top of a pump as I always felt I had done my research on a coin and wanted to hold it for a long time so why would I sell? After some time though I would read about something new or I would find out of dodgy relationships of a coin I had and would want to exit my position and then I would rebalance my portfolio in to a coin I thought was either technologically superior or didn’t have the nefarious connections to people I had come across doing conspiracy research. Because I had been right in to the conspiracy and the decentralisation tropes I guess I always carried a bit of an antiauthoritarian/anarchist bias and despite participating in a ridiculously capitalistic market, was kind of against capitalism and looking to a blockchain protocol to support something along the lines of an open source anarchosyndicalist cryptocommune. I told myself I was investing in the tech and believed in the collective endeavour of the open source project and ultimately had faith some mysterious “they” would develop a protocol that would emancipate us from this debt slavery complex.
As I became more and more aware of how to spot artificial discussion on the chans, I began to seek out further some of the radical projects like vtorrent and skycoin and I guess became a bit carried away from being amidst such ridiculous overt shilling as on the boards so that if you look in my post history you can even see me promoting some of these coins to communities I thought might be sympathetic to their use case. I didn’t see it at the time because I always thought I was holding the coins with the best tech and wanted to ride them up as an investor who believed in them, but this kind of promotion is ultimately just part of a mentality that’s pervasive to the cryptocurrency “community” that insists because it is a decentralised project you have to in a way volunteer to inform people about the coin since the more decentralised ones without premines or DAO structures don’t have marketing budgets, or don’t have marketing teams. In the guise of cultivating a community, groups form together on social media platforms like slack, discord, telegram, twitter and ‘vote’ for different proposals, donate funds to various boards/foundations that are set up to give a “roadmap” for the coins path to greatness and organise marketing efforts on places like reddit, the chans, twitter. That’s for the more grass roots ones at least, there are many that were started as a fork of another coin, or a ICO, airdrop or all these different ways of disseminating a new cryptocurrency or raising funding for promising to develop one. Imagine the operations that can be run by a team that raised millions, hundreds of millions or even billions of dollars on their ICOs, especially if they are working in conjunction with a new niche of cryptocurrency media that’s all nepotistic and incestuous.
About a year and a half ago I published another piece called “Bitcoin is about to be dethroned” (https://www.reddit.com/C\_S\_T/comments/7ewmuu/bitcoin\_is\_about\_to\_be\_dethroned/) where I felt I had come to realise the scaling debate had been corrupted by a company called Blockstream and they had been paying for social media operations in a fashion not to dissimilar to correct the record or such to control the narrative around the scaling debate and then through deceit and manipulation curated an apparent consensus around their narrative and hijacked the bitcoin name and ticker (BTC). I read the post again just before posting this and decided to refer to it to to add some kind of continuity to my story and hopefully save me writing so much out. Looking back on something you wrote is always a bit cringey especially because I can see that although I had made it a premise post, I was acting pretty confident that I was right and my tongue was acidic because of so much combating of shills on /biz/ but despite the fact I was wrong about the timing I stand by much of what I wrote then and want to expand upon it a bit more now.
The fork of the bitcoin protocol in to bitcoin core (BTC) and bitcoin cash (BCH) is the biggest value fork of the many that have occurred. There were a few others that forked off from the core chain that haven’t had any kind of attention put on them, positive or negative and I guess just keep chugging away as their own implementation. The bitcoin cash chain was supposed to be the camp that backed on chain scaling in the debate, but it turned out not everyone was entirely on board with that and some players/hashpower felt it was better to do a layer two type solution themselves although with bigger blocks servicing the second layer. Throughout what was now emerging as a debate within the BCH camp, Craig Wright and Calvin Ayre of Coin Geek said they were going to support massive on chain scaling, do a node implementation that would aim to restore bitcoin back to the 0.1.0 release which had all kinds of functionality included in it that had later been stripped by Core developers over the years and plan to bankrupt the people from Core who changed their mind on agreeing with on-chain scaling. This lead to a fork off the BCH chain in to bitcoin satoshis vision (BSV) and bitcoin cash ABC.

The premise for this post is that Craig S Wright was Satoshi Nakamoto. It’s an interesting premise because depending upon your frame of reference the premise may either be a fact or to some too outrageous to even believe as a premise. Yesterday it was announced via CoinGeek that Craig Steven Wright has been granted the copyright claim for both the bitcoin white-paper under the pen name Satoshi Nakamoto and the original 0.1.0 bitcoin software (both of which were marked (c) copyright of satoshi nakamoto. The reactions to the news can kind of be classified in to four different reactions. Those who heard it and rejected it, those who heard it but remained undecided, those who heard it and accepted it, and those who already believed he was. Apparently to many the price was unexpected and such a revelation wasn’t exactly priced in to the market with the price immediately pumping nearly 100% upon the news breaking. However, to some others it was a vindication of something they already believed. This is an interesting phenomena to observe. For many years now I have always occupied a somewhat positively contrarian position to the default narrative put forward to things so it’s not entirely surprising that I find myself in a camp that holds the minority opinion. As you can see in the bitcoin dethroned piece I called Craig fake satoshi, but over the last year and bit I investigated the story around Craig and came to my conclusion that I believed him to be at least a major part of a team of people who worked on the protocol I have to admit that through reading his articles, I have kind of been brought full circle to where my contrarian opinion has me becoming somewhat of an advocate for “the system’.
https://coingeek.com/bitcoin-creator-craig-s-wright-satoshi-nakamoto-granted-us-copyright-registrations-for-bitcoin-white-paper-and-code/

When the news dropped, many took to social media to see what everyone was saying about it. On /biz/ a barrage of threads popped up discussing it with many celebrating and many rejecting the significance of such a copyright claim being granted. Immediately in nearly every thread there was a posting of an image of a person from twitter claiming that registering for copyright is an easy process that’s granted automatically unless challenged and so it doesn’t mean anything. This was enough for many to convince them of the insignificance of the revelation because of the comment from a person who claimed to have authority on twitter. Others chimed in to add that in fact there was a review of the copyright registration especially in high profile instances and these reviewers were satisfied with the evidence provided by Craig for the claim. At the moment Craig is being sued by Ira Kleiman for an amount of bitcoin that he believes he is entitled to because of Craig and Ira’s brother Dave working together on bitcoin. He is also engaged in suing a number of people from the cryptocurrency community for libel and defamation after they continued to use their social media/influencer positions to call him a fraud and a liar. He also has a number of patents lodged through his company nChain that are related to blockchain technologies. This has many people up in arms because in their mind Satoshi was part of a cypherpunk movement, wanted anonymity, endorsed what they believed to be an anti state and open source technologies and would use cryptography rather than court to prove his identity and would have no interest in patents.

If you listen to Craig with an open mind, what cannot be denied is the man is bloody smart. Whether he is honest or not is up to you to decide, but personally I try to give everyone the benefit of the doubt and then cut them off if i find them to be dishonest. What I haven’t really been able to do with my investigation of craig is cut him off. There have been many moments where I disagree with what he has had to say but I don’t think people having an opinion about something that I believe to be incorrect is the same as being a dishonest person. It’s very important to distinguish the two and if you are unable to do so there is a very real risk of you projecting expectations or ideals upon someone based off your ideas of who they are. Many times if someone is telling the truth but you don’t understand it, instead of acknowledging you don’t understand it, you label them as being stupid or dishonest. I think that has happened to an extreme extent with Craig. Let’s take for example the moment when someone in the slack channel asked Craig if he had had his IQ tested and what it was. Craig replied with 179. The vast majority of people on the internet have heard someone quote their IQ before in an argument or the IQ of others and to hear someone say such a score that is actually 6 standard deviations away from the mean score (so probably something like 1/100 000) immediately makes them reject it on the grounds of probability. Craig admits that he’s not the best with people and having worked with/taught many high functioning people (sometimes on the spectrum perhaps) on complex anatomical and physiological systems I have seen some that also share the same difficulties in relating to people and reconciling their genius and understandings with more average intelligences. Before rejecting his claim outright because we don’t understand much of what he says, it would be prudent to first check is there any evidence that may lend support to his claim of a one in a million intelligence quotient.

Craig has mentioned on a number of occasions that he holds a number of different degrees and certifications in relation to law, cryptography, statistics, mathematics, economics, theology, computer science, information technology/security. I guess that does sound like something someone with an extremely high intelligence could achieve. Now I haven’t validated all of them but from a simple check on Charles Sturt’s alumni portal using his birthday of 23rd of October 1970 we can see that he does in fact have 3 Masters and a PhD from Charles Sturt. Other pictures I have seen from his office at nChain have degrees in frames on the wall and a developer published a video titled Craig Wright is a Genius with 17 degrees where he went and validated at least 8 of them I believe. He is recently publishing his Doctorate of Theology through an on-chain social media page that you have to pay a little bit for access to sections of his thesis. It’s titled the gnarled roots of creation. He has also mentioned on a number of occasions his vast industry experience as both a security contractor and business owner. An archive from his LinkedIn can be seen below as well.

In fact here is an on chain collection of articles and videos relating to Craig called the library of craig - https://www.bitpaste.app/tx/94b361b205196560d1bd09e4e3b3ec7ad6bea478af204cabfe243efd8fc944dd


So there is a guy with 17 degrees, a self professed one in a hundred thousand IQ, who’s worked for Australian Federal Police, ASIO, NSA, NASA, ASX. He’s been in Royal Australian Air Force, operated a number of businesses in Australia, published half a dozen academic papers on networks, cryptography, security, taught machine learning and digital forensics at a number of universities and then another few hundred short articles on medium about his work in these various domains, has filed allegedly 700 patents on blockchain related technology that he is going to release on bitcoin sv, copyrighted the name so that he may prevent other competing protocols from using the brand name, that is telling you he is the guy that invented the technology that he has a whole host of other circumstantial evidence to support that, but people won’t believe that because they saw something that a talking head on twitter posted or that a Core Developer said, or a random document that appears online with a C S Wright signature on it that lists access to an address that is actually related to Roger Ver, that’s enough to write him off as a scam. Even then when he publishes a photo of the paper copy which appears to supersede the scanned one, people still don’t readjust their positions on the matter and resort back to “all he has to do is move the coins or sign a tx”.

Yes Craig was on the Cypherpunk mailing list back in the day, but that doesn’t mean that he was or is an anarchist. Or that he shares the same ideas that Code Is Law that many from the crypto community like to espouse. I myself have definitely been someone to parrot the phrase myself before reading lots of Craig’s articles and trying to understand where he is coming from. What I have come to learn from listening and reading the man, is that although I might be fed up with the systems we have in place, they still exist to perform important functions within society and because of that the tools we develop to serve us have to exist within that preexisting legal and social framework in order for them to have any chance at achieving global success in replacing fiat money with the first mathematically provably scarce commodity. He says he designed bitcoin to be an immutable data ledger where everyone is forced to be honest, and economically disincentivised to perform attacks within the network because of the logs kept in a Write Once Read Many (WORM) ledger with hierarchical cryptographic keys. In doing so you eliminate 99% of cyber crime, create transparent DAO type organisations that can be audited and fully compliant with legislature that’s developed by policy that comes from direct democratic voting software. Everyone who wants anonymous coins wants to have them so they can do dishonest things, illegal things, buy drugs, launder money, avoid taxes.

Now this triggers me a fair bit as someone who has bought drugs online, who probably hasn’t paid enough tax, who has done illegal things contemplating what it means to have that kind of an evidence ledger, and contemplate a reality where there are anonymous cryptocurrencies, where massive corporations continue to be able to avoid taxes, or where methamphetamine can be sold by the tonne, or where people can be bought and sold. This is the reality of creating technologies that can enable and empower criminals. I know some criminals and regard them as very good friends, but I know there are some criminals that I do not wish to know at all. I know there are people that do horrific things in the world and I know that something that makes it easier for them is having access to funds or the ability to move money around without being detected. I know arms, drugs and people are some of the biggest markets in the world, I know there is more than $50 trillion dollars siphoned in to off shore tax havens from the value generated as the product of human creativity in the economy and how much human charity is squandered through the NGO apparatus. I could go on and on about the crappy things happening in the world but I can also imagine them getting a lot worse with an anonymous cryptocurrency. Not to say that I don’t think there shouldn’t be an anonymous cryptocurrency. If someone makes one that works, they make one that works. Maybe they get to exist for a little while as a honeypot or if they can operate outside the law successfully longer, but bitcoin itself shouldn’t be one. There should be something a level playing field for honest people to interact with sound money. And if they operate within the law, then they will have more than adequate privacy, just they will leave immutable evidence for every transaction that can be used as evidence to build a case against you committing a crime.

His claim is that all the people that are protesting the loudest about him being Satoshi are all the people that are engaged in dishonest business or that have a vested interest in there not being one singular global ledger but rather a whole myriad of alternative currencies that can be pumped and dumped against one another, have all kinds of financial instruments applied to them like futures and then have these exchanges and custodial services not doing any Know Your Customer (KYC) or Anti Money Laundering (AML) processes. Bitcoin SV was delisted by a number of exchanges recently after Craig launched legal action at some twitter crypto influencetalking heads who had continued to call him a fraud and then didn’t back down when the CEO of one of the biggest crypto exchanges told him to drop the case or he would delist his coin. The trolls of twitter all chimed in in support of those who have now been served with papers for defamation and libel and Craig even put out a bitcoin reward for a DOX on one of the people who had been particularly abusive to him on twitter. A big european exchange then conducted a twitter poll to determine whether or not BSV should be delisted as either (yes, it’s toxic or no) and when a few hundred votes were in favour of delisting it (which can be bought for a couple of bucks/100 votes). Shortly after Craig was delisted, news began to break of a US dollar stable coin called USDT potentially not being fully solvent for it’s apparent 1:1 backing of the token to dollars in the bank. Binance suffered an alleged exchange hack with 7000 BTC “stolen” and the site suspending withdrawals and deposits for a week. Binance holds 800m USDT for their US dollar markets and immediately once the deposits and withdrawals were suspended there was a massive pump for BTC in the USDT markets as people sought to exit their potentially not 1:1 backed token for bitcoin. The CEO of this exchange has the business registered out of Malta, no physical premises, the CEO stays hotel room to hotel room around the world, has all kind of trading competitions and the binance launchpad, uses an unregistered security to collect fees ($450m during the bear market) from the trading of the hundreds of coins that it lists on its exchange and has no regard for AML and KYC laws. Craig said he himself was able to create 100 gmail accounts in a day and create binance accounts with each of those gmail accounts and from the same wallet, deposit and withdraw 1 bitcoin into each of those in one day ($8000 x 100) without facing any restrictions or triggering any alerts or such.
This post could ramble on for ever and ever exposing the complexities of the rabbit hole but I wanted to offer some perspective on what’s been happening in the space. What is being built on the bitcoin SV blockchain is something that I can only partially comprehend but even from my limited understanding of what it is to become, I can see that the entirety of the crypto community is extremely threatened as it renders all the various alt coins and alt coin exchanges obsolete. It makes criminals play by the rules, it removes any power from the developer groups and turns the blockchain and the miners in to economies of scale where the blockchain acts as a serverless database, the miners provide computational resources/storage/RAM and you interact with a virtual machine through a monitor and keyboard plugged in to an ethernet port. It will be like something that takes us from a type 0 to a type 1 civilisation. There are many that like to keep us in the quagmire of corruption and criminality as it lines their pockets. Much much more can be read about the Cartel in crypto in the archive below. Is it possible this cartel has the resources to mount such a successful psychological operation on the cryptocurrency community that they manage to convince everyone that Craig is the bad guy, when he’s the only one calling for regulation, the application of the law, the storage of immutable records onchain to comply with banking secrecy laws, for Global Sound Money?

https://archive.fo/lk1lH#selection-3671.46-3671.55

Please note, where possible, images were uploaded onto the bitcoin sv blockchain through bitstagram paying about 10c a pop. If I wished I could then use an application etch and archive this post to the chain to be immutably stored. If this publishing forum was on chain too it would mean that when I do the archive the images that are in the bitstragram links (but stored in the bitcoin blockchain/database already) could be referenced in the archive by their txid so that they don’t have to be stored again and thus bringing the cost of the archive down to only the html and css.

Cosmos — an early in-depth analysis at the ecosystem of connected blockchains — Part One

Cosmos — an early in-depth analysis at the ecosystem of connected blockchains — Part One
This is part one of three articles where i will discuss what i have learnt whilst looking into Cosmos. I will provide links throughout the article to provide reference to sections as well as a list of sources at the bottom of the article for you to look into specific areas in more detail if required. Hopefully it will be useful for those interested in learning more about the project.
Cosmos is still very early in development process with components such as IBC which connects two blockchains together currently in research / specification stage, as a result can change by the time its released.

What is Cosmos?

Cosmos is a network and a framework for interoperability between blockchains. The zones are powered by Tendermint Core, which provides a high-performance, consistent, secure PBFT-like consensus engine, where strict fork-accountabilityguarantees hold over the behaviour of malicious actors. Cosmos is not a product but an ecosystem built on a set of modular, adaptable and interchangeable tools.
In Tendermint, consensus nodes go through a multi-round voting proposal process first before coming to consensus on the contents of a block. When 2/3 of those nodes decide on a block, then they run it through the state transition logic providing instant finality. In current proof of work consensus for Ethereum, the consensus process is inverted, where miners pick the transactions to include in a block, run state updates, then do “work” to try and mine the block.
Tendermint BFT can handle up to thousands of transactions per second (depending on the number of validators). However, this only takes into account the consensus part, the application layer is the limiting factor though. Ethermint (described below) has achieved up to 200 tps to give you an idea of the speed available per blockchain which is significantly more than current versions of Ethereum and Bitcoin etc.
The Tendermint consensus is used in a wide variety of projects, some of the most notable include Binance Chain, Hyperledger Burrow. It’s important to note though that just using Tendermint consensus doesn’t mean they can connect to other chains with the cosmos ecosystem, they would need to fork their code to implement IBC as a native protocol to allow interoperability through IBC.
see https://raw.githubusercontent.com/devcorn/hackatom/mastetminfo.pdf for high res

The Tendermint consensus algorithm follows a traditional approach which relies on all validators to communicate with one another to reach consensus. Because of the communication overhead, it does not scale to 1000s of validators like Bitcoin or Ethereum, which can have an unlimited number of validators. Tendermint works when there are 100s of validators. (Cosmos Hub currently has a maximum of 100 validators and the maximum tested so far with Tendermint is 180 validators)
Therefore, one of the downsides of a blockchain built using Tendermint is that, unlike Bitcoin or Ethereum, it requires the validators to be known ahead of time and doesn’t allow for miners to come and go as they please.Besides this, it also requires the system to maintain some notion of time, which is known to be a complex problem in theory. Although in practice, Tendermint has proven this can be done reasonably well if you use the timestamp aggregates of each node.
In this regard, one could argue that Tendermint consensus protocol is “less decentralized” than Bitcoin because there are fewer validators, and they must be known ahead of time.
Tendermint’s protocol guarantees safety and liveness, assuming more than 2/3 of the validators’ voting power is not Byzantine (i.e., malicious). In other words, if less than 1/3 of the network voting power is Byzantine, the protocol can guarantee safety and liveness (i.e., validators will never commit conflicting blocks at the same height and the blockchain continues to make progress).https://www.preethikasireddy.com/posts/how-does-cosmos-work-part1
To see the process of how Tendermint works please see this diagram as well as more info here

Sovereignty

Cosmos goal is to provide sovereignty through governance to developers by making it easy to build blockchains via the Cosmos SDK and provide interoperability between them, using Tendermint consensus. This is their main differentiator compared to competition like Polkadot and Ethereum 2.0. Ethereum 2.0 and Polkadot are taking a different approach by only using shared security, where there is a root chain which controls the security / prevents double spending for all connected blockchains.
In Hub governance all stakers vote, the validators vote is superseded if the delegator votes directly
Governance is where all stakers vote on proposals to determine what changes are implemented in the future for their own blockchain, stakers can either choose to delegate their vote to the validator or they can instead vote directly. Without sovereignty all DAPPs share the same underlying environment. If an application requires a new feature in the EVM it has to rely entirely on the governance of the Ethereum Platform to accept it for example. However, there are also tradeoffs to having sovereignty as each zone is going to need a way to incentivise others to validate / create blocks on the Zone by running Full Nodes. Whilst it may be easy to create a blockchain using the cosmos SDK and to mint a token, there are the legal costs / regulation associated with creating your own token. How are you going to distribute the tokens? How are you going to list them on exchanges? How are you going to incentivise others to use the token without being classed as a security? All of which have led to a significant reduction in the number of ICOs being done. With every zone needing their own validator set, there’s going to be a huge number of validators required each trying to persuade them to validate their zone with only a finite number of validators available.
Each Zone / App is essentially a mini DAO and not all are going to be comfortable about having their project progress been taken out of their hands and instead relying on the community to best decide on the future (unless they control 2/3 of the tokens). The Cosmos Hub has proved this can be successful, but others may be risk averse to having their application be a mini DAO. Should someone / competitor acquire 1/3 of the tokens of a zone then they could potentially prevent any further progress being made by rejecting all governance votes (this would be very costly to do on the Cosmos Hub due to its high amount staked, but for all the other less secure zones this potentially may be an issue).
Security for some zones will likely be a lot lower with every developer needing to validate their own blockchain and tokenise them with POS with no easy way to validate the setup of a validator to ensure its secure. Whilst the Cosmos hub is very secure with its current value staked, how secure zone’s will be with significantly less staked remains to be seen. Whilst providing soverignty was Cosmos’s main goal from the start, they are also looking at being able to provide shared security by having validators of a connected Hub also validate /create new blocks on the connected zone’s blockchain for them as well. They are still going to need some way to incentivise the validators to this. Another option is if the developers didn’t want to create a token, nor want sovereignty etc, then they could just build a DAPP on the EVM on a zone such as Ethermint.
As can be seen their are potential advantages and disadvantages to each method, but rather than forcing shared security like Ethereum and Polkadot, Cosmos is giving the developer the choice so will be interesting to see which they prefer to go for.

Layers of a blockchain

From an architecture standpoint, each blockchain can be divided into three conceptual layers:
  • Application: Responsible for updating the state given a set of transactions, i.e. processing transactions.
  • Networking: Responsible for the propagation of transactions and consensus-related messages.
  • Consensus: Enables nodes to agree on the current state of the system.
The state machine is the same as the application layer. It defines the state of the application and the state-transition functions. The other layers are responsible for replicating the state machine on all the nodes that connect to the network.
The Cosmos SDK is a generalized framework that simplifies the process of building secure blockchain applications on top of Tendermint BFT. The goal of the Cosmos SDK is to create an ecosystem of modules that allows developers to easily spin up application-specific blockchains without having to code each bit of functionality of their application from scratch. Anyone can create a module for the Cosmos SDK and using ready built modules in your blockchain is as simple as importing them into your application.
The Tendermint BFT engine is connected to the application by a socket protocol called the Application Blockchain Interface (ABCI). This protocol can be wrapped in any programming language, making it possible for developers to choose a language that fits their needs.

Hub and Spoke Topology

Cosmos follows a hub and spoke topology as its not feasible to connect every zone together. If you were to connect every blockchain together the number of connections in the network would grow quadratically with the number of zones. So, if there are 100 zones in the network then that would equal 4950 connections.
Zones are regular heterogenous blockchains and Hubs are blockchains specifically designed to connect Zones together. When a Zone creates an IBC connection with a Hub, it can automatically access (i.e. send to and receive from) every other Zone that is connected to it. As a result, each Zone only needs to establish a limited number of connections with a restricted set of Hubs. Hubs also prevent double spending among Zones. This means that when a Zone receives a token from a Hub, it only needs to trust the origin Zone of this token and each of the Hubs in its path. Hubs do not verify or execute transactions committed on other zones, so it is the responsibility of users to send tokens to zones that they trust.
There will be many Hubs within Cosmos network the first Hub to launch was the Cosmos Hub whose native staking token is called ATOM. ATOM tokens are specific to just the Cosmos Hub which is one hub of many, each with their own token. Transaction fees for the Cosmos Hub will be payable in multiple tokens so not just ATOMs whereas other Hubs such as IRIS has made it so that all transaction fees are paid in IRIS for transactions on its hub.
As mentioned, the Cosmos Hub is one of many hubs in the network and currently has a staking ratio of around 70% with its token ATOM having a market cap of just over $800 million. IRISnet was the second Hub to launch which currently has around 28% bonded with its token IRIS which has a market cap of just under $17 million. The Third Hub about to be launched later this month has its token SENT which has a market cap of around $3.4 million. As you can see the security of these 3 hubs differ wildly and as more and more hubs and then zones are brought online there is going to need to be a lot of tokens / incentivisation for validators.
Ethermint
Standard Cosmos zones / hubs don’t have smart contract functionality and so to enable this, as the Application layer is abstracted from the consensus layer via ABCI API described earlier, it allows Cosmos to port the code over from other blockchains such as Ethereum and use it with the Tendermint Consensus to provide access to the Ethereum Virtual Machine. This is what is called Ethermint.
This allows developers to connect their zones to specialised zones such as Ethermint to build and run smart contracts based on Solidity, whilst benefiting from the faster performance of the tendermint Conensus over the existing POW implementation currently. Whereas a normal Go Ethereum process runs at ~12.5 transactions per second (TPS), Ethermint caps out at 200 TPS. This is a comparison against existing Ethereum speeds, whilst obviously Ethereum are working on their own scaling solutions with Ethereum 2.0 which will likely be ready around the same time. Existing tools / dapps used on ethereum should easily be able to be ported over to Ethermint by the developer if required.
In addition to vertical scaling (with the increase in tps by using Tendermint consensus), it can also have multiple parallel chains running the same application and operated by a common validator set. So if 1 Ethermint zone caps out at 200 TPS then 4 Ethermint zones running in parallel would theoretically cap out at 800 TPS for example.

There is a huge number of developers / apps currently built on Ethereum, should a developer choose to migrate their DAPP over to Ethermint they would lose native compatibility with those on Ethereum (except through Peg Zone), but would gain compatibility with those running on Ethermint and others in the cosmos ecosystem.
You can find out more about Ethermint here and here

IBC

IBC stands for inter-blockchain communication protocol and is an end-to-end, connection-oriented, stateful protocol for reliable, ordered, authenticated communication between modules on separate distributed ledgers. Ledgers hosting IBC must provide a certain set of functions for consensus transcript verification and cryptographic commitment proof generation, and IBC packet relayers (off-chain processes) are expected to have access to network protocols and physical datalinks as required to read the state of one ledger and submit data to another.
In the IBC architecture, modules are not directly sending messages to each other over networking infrastructure, but rather creating messages to be sent which are then physically relayed via “Relayers”. “Relayers” run off-chain and continuously scan the state of each ledger via a light client connected to each of the 2 chains and can also execute transactions on another ledger when outgoing datagrams have been committed. For correct operation and progress in a connection between two ledgers, IBC requires only that at least one correct and live relayer process exists which can relay between the ledgers. Relays will need to be incentivised to perform this task (the method to which hasn’t been established as of this writing)
The relay process must have access to accounts on both chains with sufficient balance to pay for transaction fees. Relayers may employ application-level methods to recoup these fees, such by including a small payment to themselves in the packet data. More information on Relayers can be found here

https://preview.redd.it/qr4k6cxtmba31.png?width=1100&format=png&auto=webp&s=d79871767ced4bcb0b2632cc137c118f70c3863a
A high-level overview of the process is that Zone 1 commits an outbound message on its blockchan about sending say 1 x Token A to Hub1 and puts 1 x Token A in escrow. Consensus is reached in Zone 1, and then it’s passed to the IBC module to create a packet which contains the reference to the committed block, source and destination channel/ connection and timeout details and is added to Zone 1’s outbound queue as proof.
All relayers (who run off-chain) are continuously monitoring the state of Zone 1 via the Zone 1 light client. A Relayer such as Relayer 1 is chosen and submits a proof to Hub1 that Zone 1.
Hub 1 then sends a receipt as proof that it has received the message from Zone 1, relayer1 sends it to Zone 1. Zone 1 then removes it from its outbound queue and sends proof via another receipt to Hub1. Hub1 verifies the proof and mints the token.

https://preview.redd.it/qn7895rumba31.png?width=770&format=png&auto=webp&s=96d9d808b2284f87d45fa0bd7b8bff297c86c2da
This video below explains the process in more detail as well as covers some of the other points i raise later in this article so worth a watch (time stamped from 22:24 to 32:25) and also here from 38:53 to 42:50
https://youtu.be/5h8DXul4lH0?t=1344
Whilst there is an option for UDP style transfer where a zone will send a message to a Hub and it doesn’t care whether it gets there or in any order etc, Token transfers are going to require the TCP style connections in IBC where there is a send, receipt and then another receipt as explained above. Each Send, receipt followed by another receipt is going to take at least 2 blocks and so using Cosmos Hub block times as an example with 6.88 second block times a transfer between one zone and hub could take a minimum of 41.28 seconds. You also then have to factor in the amount of other transactions going through those at that time and relevant gas price to see whether it is able to use 2 consecutive blocks or whether it may take more. This is also explained in this video “ILP Summit 2019 | Cosmos and Interledger | Sunny Aggarwal” (time stamped) from to 12:50 to 15:45

In Part Two we will look at potential issues with multi hop routing, token transfers across multiple routes and Peg Zones, whilst also looking at other interoperability solutions that would resolve some of these issues and compliment the cosmos ecosystem. Part Two can be found here
