Weekly Update: $WIB, $VID, $CHZ on ParJar, Pynk crushes Web Summit, XIO swap bridge, Sentivate reorg... – 1 Nov - 7 Nov'19
Hi folks! We are catching up real quick. Here’s your week at Parachute + partners (1 Nov - 7 Nov'19):

Three new projects and their awesome communities joined the Parachute fam this week: Wibson, VideoCoin and Chiliz. Welcome! And if you missed, we also added Shuffle Monster, Harmony and CyberFM last week. #cryptoforeveryone is getting bigger by the day. Woot woot! In this week’s TTR trivias, we had Richi’s movie quiz qith a 25k $PAR pot. Charlotte's Rebus trivia in TTR on Tuesday had 25k $PAR in prizes for 10 Qs. Noice! Jason’s creative contest for this week was #artdeadmin: “draw/paint/sketch/whatever you imagine a group of the parachute admins doing together”. Click here to check out some of the entries of the TTR Halloween photo contest from last week. Doc Victor (from Cuba) hosted a Champions League wager round in tip room. And congrats to Victor (Anox) for passing his final Medical exams. We have 2 Doc Vics now. One from Cuba and the other from *redacted*.
Some of the top #artdeadmin submissions. Insane talent!
Jason’s running medal collection. Say what!
Andy shared the latest standings in the Parachute Fantasy Football League (#PFFL). Clinton (7-2) is on top followed by Chris (7-2) in second place and Hang (7-2) in third place. So close! As we rolled into November, Parachute crew signed up for Movember. So now we have 3 teams from the Parachute fold, doing a no-shave November for men’s health issues: Parachute (Tony, Cap, Alexis, Cuban Doc Vic, Richi), TTR (Vali, Ashok, Tavo, Alejandro, Marcos, PeaceLove) and TTR-Ladies (Mery, Martha, AngellyC, Liem, Durby, LeidyElena, Charlotte). Show them some support peeps! This is all for charity. Show them some support folks! This week’s #wholesomewed was about “your most precious possession and give us the story of why it is so precious to you”. A whole lot of $PAR was given out for some real wholesome life stories. Best. Community. Eva! Two-for-Tuesday theme for this week: colors! As always, a melodic Tuesday thanks to Gian! And thank you Borna for writing about Parachute and ParJar on the Blockchain Andy blog.
<- This is where Jose creates his magic. Respect / Cuban Doc Vic’s doggo, Symba, could easily be a TTR mascot. Good boi! ->
This week at aXpire there were two separate $AXPR burns: 20k of last week and 200k of this week. Last week’s news recap can be seen here. Congratulations to the team for being conferred the honour of being handed a key to Miami-Dade County by Mayor Carlos A. Gimenez at the 2019 Miami-Dade Beacon Council Annual Meeting & Key Ceremony. aXpire's disruptive solutions like Resolvr (expense allocation), Bilr (invoice management) and DigitalShares (deal marketplace) help hedge funds and PE firms scale through better profit margins. How? Read here. Did you know that the 2gether Ambassador Zone lets you customise referral messages with a #PicOfTheDay while you earn some sweet 2GT rewards? Super cool! There was an upgrade to the platform this week that might have led to a temporary deactivation in withdrawals while the update was being deployed. CEO Ramón Ferraz’s interview by BeInCrypto was released. Founder Salvador Algarra travelled to an ABANCA event for a keynote speech on Fintech innovation. Next week he will be at Rankia's Blockchain and Crypto Tech gathering to speak on "Blockchain, from predicting the future to building it". CardRates’ feature article on 2gether came out this week. The BOMBX:XIO token swap bridge went live. The swap will be open till 15th December. Plus, $XIO is now listed on DDEX and Switcheo. There were some disruptions in the bridge from time to time because of heavy traffic. Hence, the team also set up a manual swap page as an alternative solution. And please be wary of scammers posing as admins to help with the swap instructions. For any doubts, always reach out to accounts with admin tags on the official Telegram channel. The first set of incubated startups will be revealed on the 22nd of November. Ever wanted to find out about the people who frequent the BOMB token chat? Well, the BOMB Board is running a "Humans of Bomb" series to feature some of the most active members. This week, say Hello to Gustavo.
Key to Miami-Dade County awarded to aXpire. Cool!
WednesdayCoin’s founder Mike floated the idea of making WednesdayClub open on all days. The nature of the $WED token will not change on chain. Just that it will be usable inside the DApp everyday. What do you think? Let him know in the Reddit thread. Birdchain’s $BIRD token was listed on Mercatox this week. A new monthly referral contest was launched as well. 50k BIRD tokens to be won. Nice! Want the SMS feature to be released in your country? Start promoting! A featured article on Chainleak capped off the week perfectly for Birdchain. $ETHOS, $AXPR (aXpire), $HYDRO, $BNTY (Bounty0x) and $HST (Horizon State) were added to the eToro Wallet. The airdrops for Switch’s various token holders were distributed this week. As mentioned earlier as well, $ESH and $SDEX are revenue sharing tokens. Winners of the John McAfee contest and trading competition were announced. Congratulations! Tron blockchain support will be added to the Switch-based McAfeeDex next week. The news was covered by Beincrypto, U Today, Crypto Crunch, Altcoin Buzz and Tron’s Justin Sun as well. The Dex was featured in a Forbes article about John McAfee’s views on Libra. The latest community contest at Fantom involves writing educational articles on the platform. If you have been following Fantom developments, then this would be a breeze. Also, USD 100 in FTM tokens to be won. Sweet! Check out the cool $FTM merch on display at Odd Gems fashion. Even though these are not official gear, they have the blessings from the project. CMO Michael Chen sat down for an interview with Crypto Intelligence India to talk about the upcoming mainnet launch. The crew also appeared for an AMA with Atomic Wallet community.

CZ Crypto Deepfake is Funny Now, But it May Not be So Amusing Soon

CZ Crypto Deepfake is Funny Now, But it May Not be So Amusing Soon
A deepfake of crypto trading master CZ is out, entertaining the Cryptoverse. But deepfakes, entering this industry may not be so funny in the near future.
https://preview.redd.it/cm58ci60e3x31.jpg?width=692&format=pjpg&auto=webp&s=8fedc326046c1856008a184441b5a665994e20fb
In a deepfake video, published today, we see the CEO of major cryptocurrency exchange Binance, Changpeng Zhao (CZ), and his followers celebrating Bitcoin (BTC) mooning in the Binance Trading Lab, while the fiat banker looks on. The celebration is followed by CZ’s crypto trading advice. And all of this is set in a classic Chinese Kung Fu movie, or to be more precise – CZ’s face is set in a movie. The clip ends with a disclaimer saying that the deepfake is created to raise awareness about synthetic or AI-generated media, by Alethea, which is building AI-powered decentralized applications (dapps) aimed at helping users identify deepfakes and not be manipulated by their content.
And this is also our point here. While a particular deepfake may be amusing, it’s not difficult to imagine people using this technology for a more nefarious purpose. What is a deepfake? Shortly and simply, it’s an AI-based face-swap. This deep learning technology can be used to create or alter video content so that it presents, in a disturbingly convincing manner, something that never happened. It has been used since two years ago to edit the faces of celebrities onto actors in pornographic videos, and since then a number of clips have been produced of famous people saying or doing something which never occurred. Here is another example:
Now let’s turn to crypto specifically, and take two real recent examples that affected the market. With fake news circulating that police raided the Beijing Tron offices, TRX price fell 5%. China’s President Xi Jinping urged the country to accelerate the development of blockchain technology, after which – whether due to his words or not – BTC exploded, altcoins rallied, and six China-based coins saw a particularly large rise. These are just two of many examples that prove that the words and actions by a single person or organization can move the market significantly.
Now, imagine a person – one with a liking for criminal activities – holding some TRX, let’s say, and they want to earn more money than it’s (legally) possible at that given time. They produce a video of "Justin Sun" saying that Tron just made a multi-billion partnership with Microsoft, Apple, JP Morgan and McDonald's at the same time. (Or it could be "Charlie Lee", saying the same about Litecoin (LTC)). Imagine this person wanting to push the price of TRX up super quickly, but also bring Binance Coin (BNB) down at the same time for whatever reason, so a video with CZ saying Binance is under attack comes out, and millions in funds have been lost, personal data stolen, the whole catastrophic mess. This person may buy TRX or LTC for USD 100,000 and sell it for USD 200,000 in the short time somebody needs to figure out the video is a deepfake. At that point, the pump and dump deed is done and there’s nothing anybody can do about it.
Moreover, we already have myriad of Twitter scammers that stole millions from crypto owners without any AI, just by editing a few pictures and creating fake Twitter accounts. It wouldn't be a surprise if one day 'Master CZ' releases a video and asks to send him 1 BTC so he could send back two.

AMA with Wanchain VP Lini

AMA with Wanchain VP Lini
Original article here: https://medium.com/wanchain-foundation/ama-with-wanchain-vp-lini-58ada078b4fe

“What is unique about us is that we have actually put theory into practice.”
— Lini
https://preview.redd.it/n6lo2xcmtn621.png?width=800&format=png&auto=webp&s=281acce4b45eed8acf0c52b201d01cb6f0d13507
https://preview.redd.it/10aj3ointn621.png?width=800&format=png&auto=webp&s=6a187e8a6eb5ac0445ddc73d5b0f9077f12bce39
Wanchain’s Vice President of Business Development, Lini, sat down with blockchain media organization Neutrino for an AMA covering a wide range of topics concerning Wanchain’s development.
The following is an English translation of the original Chinese AMA which was held on December 13th, 2018:
Neutrino: Could you please first share with us a little basic background, what are the basic concepts behind cross chain technology? What are the core problems which are solved with cross-chain? In your opinion, what is the biggest challenge of implementing cross chain to achieve value transfer between different chains?
Lini: Actually, this question is quite big. Let me break it down into three smaller parts:
  1. First, what is the meaning of “cross-chain”?
https://preview.redd.it/cpui6t7qtn621.png?width=720&format=png&auto=webp&s=86bc39d94b0713949c150598e2397a4f9d3ac491
In China, we like to use the word “cross-chain”, the term “interoperability” is used more frequently in foreign countries. Interoperability is also one of the important technologies identified by Vitalik for the development of a future blockchain ecosystem mentioned in the Ethereum white paper. So cross-chain is basically the concept of interoperability between chains.
  1. The core problem solved by cross chain is that of “multi-ledger” synchronous accounting
https://preview.redd.it/603dl86stn621.png?width=720&format=png&auto=webp&s=425b827298ac919f8cf05909037458a173100cc4
In essence, blockchain is a distributed bookkeeping technique, also known as distributed ledger technology. Tokens are the core units of account on each chain, there currently exist many different chains, each with their own token. Of especial importance is the way in which each ledger uses tokens to interact with each other for the purpose of clearing settlements.
  1. The core purpose of the cross-chain technology is as one of the key infrastructures of the future economy based on digital currencies.
https://preview.redd.it/3d61f26utn621.png?width=720&format=png&auto=webp&s=b735482c9734e1d32176e406adce1718be20583e
Cross chain technology is one of the foundational technological infrastructures that is necessary for the large scale application of blockchain technology.
Neutrino: As we all know, there are many different kinds of cross-chain technologies. Please give us a brief introduction to several popular cross-chain technologies on the market, and the characteristics of each of these technologies。
Lini: Before answering this question, it is very important to share two important concepts with our friends: heterogeneity and homogeneity, and centralization and decentralization.
https://preview.redd.it/n6wbs77wtn621.png?width=720&format=png&auto=webp&s=83fcadd09afb214d2aa5a2a6deb6c24d0d4da671
These two points are especially important for understanding various cross-chain technologies, because there are many different technologies and terminologies, and these are some of the foundational concepts needed for understanding them.
There are also two core challenges which must be overcome to implement cross-chain:
https://preview.redd.it/84wqd28ytn621.png?width=720&format=png&auto=webp&s=dafe1cd2993f853547b532421404e6ab86e185f1
Combining the above two points, we look at the exploration of some solutions in the industry and the design concepts of other cross-chain projects.
First I’d like to discuss the Relay solution.
https://preview.redd.it/qgcqiwlztn621.png?width=720&format=png&auto=webp&s=0925d4221c9e92e365e150638c645bef8c609b3f
However the Relay solution must consume a relatively large amount of gas to read the BTC header. Another downside is that, as we all know, Bitcoin’s blocks are relatively slow, so the time to wait for verification will be long, it usually takes about 10 minutes to wait for one block to confirm, and the best practice is to wait for 6 blocks.
The next concept is the idea of Sidechains.
https://preview.redd.it/9cg79bl1un621.png?width=720&format=png&auto=webp&s=1260e14213b1757eadc4b6141a365ed3b0e20316
This solution is good, but not all chains contain SPV, a simple verification method. Therefore, there are certain drawbacks. Of course, this two way peg way solves challenge beta very well, that is, the atomicity of the transaction.
These two technical concepts have already been incorporated into a number of existing cross chain projects. Let’s take a look at two of the most influential of these.
The first is Polkadot.
https://preview.redd.it/1o3xwz93un621.png?width=720&format=png&auto=webp&s=249909a33b5420050a6010b961a944285fc94926
This is just a summary based on Polkadot’s whitepaper and most recent developments. The theoretical design is very good and can solve challenges alpha and beta. Last week, Neutrino organized a meetup with Polkadot, which we attended. In his talk, Gavin’s focus was on governance, he didn’t get into too much technical detail, but Gavin shared some very interesting ideas about chain governance mechanisms! The specific technical details of Polkadot may have to wait until after their main net is online before it can be analyzed.
Next is Cosmos.
https://preview.redd.it/5gtjf6x4un621.png?width=720&format=png&auto=webp&s=94d6408ff65dc7041316f0130867888e108848b2
Cosmos is a star project who’s basic concept is similar to Polkadot. Cosmos’s approach is based on using a central hub. Both projects both take into account the issue of heterogeneous cross-chain transactions, and both have also taken into account how to solve challenges alpha and beta.
To sum up, each research and project team has done a lot of exploration on the best methods for implementing cross-chain technology, but many are still in the theoretical design stage. Unfortunately, since the main net has not launched yet, it is not possible to have a more detailed understanding of each project’s implementation. A blockchain’s development can be divided into two parts: theoretical design, and engineering implementation. Therefore, we can only wait until after the launch of each project’s main network, and then analyze it in more detail.
Neutrino: As mentioned in the white paper, Wanchain is a general ledger based on Ethereum, with the goal of building a distributed digital asset financial infrastructure. There are a few questions related to this. How do you solve Ethereum’s scaling problem? How does it compare with Ripple, which is aiming to be the standard trading protocol that is common to all major banks around the world? As a basic potential fundamental financial infrastructure, what makes Wanchain stand out?
Lini: This question is actually composed of two small questions. Let me answer the first one first.
  1. Considerations about TPS.
First of all, Wanchain is not developed on Ethereum. Instead, it draws on some of Ethereum’s code and excellent smart contracts and virtual machine EVM and other mature technical solutions to build the mainnet of Wanchain.
The TPS of Ethereum is not high at this stage, which is limited by various factors such as the POW consensus mechanism. However, this point also in part is due to the characteristics of Ethereum’s very distributed and decentralized features. Therefore, in order to improve TPS, Wanchain stated in its whitepaper that it will launch its own POS consensus, thus partially solving the performance issues related to TPS. Wanchain’s POS is completely different from the POS mechanism of Ethereum 2.0 Casper.
Of course, at the same time, we are also paying close attention to many good proposals from the Ethereum community, such as sharding, state channels, side chains, and the Raiden network. Since blockchain exists in the world of open source, we can of course learn from other technological breakthroughs and use our own POS to further improve TPS. If we have some time at the end, I’d love to share some points about Wanchain’s POS mechanism.
  1. Concerning, Ripple, it is completely different from what Wanchain hopes to do.
Ripple is focused on exchanges between different fiat pairs, the sharing of data between banks and financial institutions, as a clearing and settlement system, and also for the application of DLT, for example the Notary agent mechanism.
Wanchain is focused on different use cases, it is to act as a bridge between different tokens and tokens, and between assets and tokens. For various cross-chain applications it is necessary to consume WAN as a gas fee to pay out to nodes.
So it seems that the purpose Ripple and Wanchain serve are quite different. Of course, there are notary witnesses in the cross-chain mechanism, that is, everyone must trust the middleman. Ripple mainly serves financial clients, banks, so essentially everyone’s trust is already there.
Neutrino: We see that Wanchain uses a multi-party computing and threshold key sharing scheme for joint anchoring, and achieves “minimum cost” for integration through cross-chain communication protocols without changing the original chain mechanism. What are the technical characteristics of multi-party computing and threshold key sharing? How do other chains access Wanchain, what is the cross-chain communication protocol here? What is the cost of “minimum cost?
Lini: The answer to this question is more technical, involving a lot of cryptography, I will try to explain it in a simple way.
  1. About sMPC -
It stands for secure multi-party computation. I will explain it using an example proposed by the scholar Andrew Yao, the only Turing Award winner in China. The scenario called Yao’s Millionaire Problem. How can two millionaires know who is wealthier without revealing the details of their wealth to each other or a trusted third party? I’m not going to explain the answer in detail here, but those who are interested can do a web search to learn more.
In sMPC multiple parties each holding their own piece of private data jointly perform a calculation (for example, calculating a maximum value) and obtain a calculation result. However, in the process, each party involved does not leak any of their respective data. Essentially sMPC calculation can allow for designing a protocol without relying on any trusted third parties, since no individual ever has access to the complete private information.
Secure multiparty computing can be abstractly understood as two parties who each have their own private data, and can calculate the results of a public function without leaking their private data. When the entire calculation is completed, only the calculation results are revealed to both parties, and neither of them knows the data of the other party and the intermediate data of the calculation process. The protocol used for secure multiparty computing is homomorphic encryption + secret sharing + OT (+ commitment scheme + zero knowledge proofs, etc.)
Wanchain’s 21 cross chain Storeman nodes use sMPC to participate in the verification of a transaction without obtaining of a user’s complete private key. Simply put, the user’s private key will have 21 pieces given to 21 anonymous people who each can only get 1/21 part, and can’t complete the whole key.
  1. Shamir’s secret sharing
There are often plots in a movie where a top secret document needs to be handed over to, let’s say five secret agents. In order to protect against the chance of an agent from being arrested or betraying the rest, the five agents each hold only part of a secret key which will reveal the contents of the documents. But there is also a hidden danger: if one the agents are really caught, how can the rest of the agents access the information in the documents? At this point, you may wonder if there is any way for the agents to still recover the original text with only a portion of the keys? In other words, is there any method that allows a majority of the five people to be present to unlock the top secret documents? In this case, the enemy must be able to manipulate more than half of the agents to know the information in the secret documents.
Wanchain uses the threshold M<=N; N=21; M=16. That is to say, at least 16 Storeman nodes must participate in multi-party calculation to confirm a transaction. Not all 21 Storeman nodes are required to participate. This is a solution to the security problem of managing private keys.
Cross-chain communication protocols refers to the different communication methods used by different chains. This is because heterogeneous cross-chain methods can’t change the mechanism of the original chains. Nakamoto and Vitalik will not modify their main chains because they need BTC and ETH interoperability. Therefore, project teams that can only do cross-chain agreements to create different protocols for each chain to “talk”, or communicate. So the essence of a cross-chain protocol is not a single standard, but a multiple sets of standards. But there is still a shared sMPC and threshold design with the Storeman nodes.
The minimum cost is quite low, as can be shown with Wanchain 3.0’s cross chain implementation. In fact it requires just two smart contracts, one each on Ethereum and Wanchain to connect the two chains. To connect with Bitcoin all that is needed is to write a Bitcoin script. Our implementation guarantees both security and decentralization, while at the same time remaining simple and consuming less computation. The specific Ethereum contract and Bitcoin scripts online can be checked out by anyone interested in learning more.
Neutrino: What kind of consensus mechanism is currently used by Wanchain? In addition, what is the consensus and incentive mechanism for cross-chain transactions, and what is the purpose of doing so? And Wanchain will support cross-chain transactions (such as BTC, ETH) on mainstream public chains, asset cross-chain transactions between the alliance chains, and cross-chain transactions between the public and alliance chains, how can you achieve asset cross-chain security and privacy?
Lini: It is now PPOW (Permissioned Proof of Work), in order to ensure the reliability of the nodes before the cross-chain protocol design is completed, and to prepare to switch to POS (as according to the Whitepaper roadmap). The cross-chain consensus has been mentioned above, with the participation of a small consensus (at least 16 nodes) in a set of 21 Storeman nodes through sMPC and threshold secret sharing.
In addition, the incentive is achieved through two aspects: 1) 100% of the cross chain transaction fee is used to reward the Storeman node; 2) Wanchain has set aside a portion of their total token reserve as an incentive mechanism for encouraging Storeman nodes in case of small cross-chain transaction volume in the beginning.
It can be revealed that Storeman participation is opening gradually and will become completely distributed and decentralized in batches. The first phase of the Storeman node participation and rewards program is to be launched at the end of 2018. It is expected that the selection of participants will be completed within one quarter. Please pay attention to our official announcements this month.
In addition, for public chains, consortium chains, and private chains, asset transfer will also follow the cross-chain mechanism mentioned above, and generally follow the sMPC and threshold integration technology to ensure cross-chain security.
When it comes to privacy, this topic will be bigger. Going back to the Wanchain Whitepaper, we have provided privacy protection on Wanchain mainnet. Simply put, the principle is using ring signatures. The basic idea is that it mixes the original address with many other addresses to ensure privacy. We also use one-time address. In this mechanism a stamp system is used that generates a one-time address from a common address. This has been implemented since our 2.0 release.
But now only the privacy protection of native WAN transactions can be provided. The protection of cross-chain privacy and user experience will also be one of the important tasks for us in 2019.
Neutrino: At present, Wanchain uses Storeman as a cross-chain trading node. Can you introduce the Storeman mechanism and how to protect these nodes?
Lini: Let me one problem from two aspects.
  1. As I introduced before in my explanation of sMPC, the Storeman node never holds the user’s private key, but only calculates the transaction in an anonymous and secure state, and the technology prevents the Storeman nodes from colluding.
  2. Even after technical guarantees, we also designed a “double protection” against the risk from an economic point of view, that is, each node participating as a Storeman needs to pledge WAN in the contract as a “stake”. The pledge of WAN will be greater than the amount of any single transaction as a guarantee against loss of funds.
If the node is malicious (even if it is a probability of one in a billion), the community will be compensated for the loss caused by the malicious node by confiscation of the staked WAN. This is like the POS mechanism used by ETH, using staking to prevent bad behavior is a common principle.
Neutrino: On December 12th, the mainnet of Wanchain 3.0 was launched. Wanchain 3.0 opened cross-chain transactions between Bitcoin, Ethereum and ERC20 (such as MakerDao’s stable currency DAI and MKR). What does this version mean for you and the industry? This upgrade of cross-chain with Bitcoin is the biggest bright spot. So, if now you are able to use Wanchain to make transactions between what is the difference between tokens, then what is the difference between a cross chain platform like Wanchain and cryptocurrency exchanges?
Lini: The release of 3.0 is the industry’s first major network which has crossed ETH and BTC, and it has been very stable so far. As mentioned above, many cross-chain, password-protected theoretical designs are very distinctive, but for engineering implementation, the whether or not it can can be achieved is a big question mark. Therefore, this time Wanchain is the first network launched in the world to achieve this. Users are welcome to test and attack. This also means that Wanchain has connected the two most difficult and most challenging public networks. We are confident we will soon be connecting other well-known public chains.
At the same time of the release of 3.0, we also introduced cross chain integration with other ERC20 tokens in the 2.X version, such as MakerDao’s DAI, MKR, LRC, etc., which also means that more tokens of excellent projects on Ethereum will also gradually be integrated with Wanchain.
Some people will be curious, since Wanchain has crossed so many well-known public chains/projects; how is it different with crypto exchanges? In fact, it is very simple, one centralized; one distributed. Back to the white paper of Nakamoto, is not decentralization the original intention of blockchain? So what Wanchain has to do is essentially to solve the bottom layer of the blockchain, one of the core technical difficulties.
Anyone trying to create a DEX (decentralized exchange); digital lending and other application scenarios can base their application on Wanchain. There is a Wanchain based DEX prototype made by our community members Jeremiah and Harry, which quite amazing. Take a look at this video below.
https://www.youtube.com/watch?v=codcqb66G6Q
Neutrino: What are the specific application use cases after the launch of Wanchain 3.0? Most are still exploring small-scale projects. According to your experience, what are the killer blockchain applications of the future? What problems need to be solved during this period? How many years does it take?
Lini:
  1. Wanchain is just a technology platform rather than positioning itself as an application provider; that is, Wanchain will continue to support the community, and the projects which use cross-chain technology to promote a wide range of use cases for Wanchain.
  2. Cross-chain applications that we anticipate include things like: decentralized exchanges, digital lending, cross chain games, social networking dAPPs, gambling, etc. We also expect to see applications using non fungible tokens, for example exchange of real assets, STOs, etc.
  3. We recently proposed the WanDAPP solution. Simply speaking, a game developer for example has been developing on Ethereum, and ERC20 tokens have been issued, but they hope to expand the player base of their games to attract more people. To participate and make full use of their DAPP, you can consider using the WanDAPP solution to deploy the game DAPP on other common platforms, such as EOS, TRON, etc., but you don’t have to issue new tokens on these chains or use the previous ERC20 tokens. In this way the potential user population of the game can be increased greatly without issuing more tokens on a new chain, improving the real value of the original token. This is accomplished completely using the cross-chain mechanism of Wanchain.
  4. For large-scale applications, the infrastructure of the blockchain is not yet complete, there are issues which must first be dealt with such as TPS, sharding, sidechains, state channels, etc. These all must be solved for the large-scale application of blockchain applications. I don’t dare to guess when it will be completed, it depends on the progress of various different technical projects. In short, industry practitioners and enthusiasts need a little faith and patience.
Neutrino community member Block Venture Capital Spring: Will Wanchain be developing any more cross chain products aimed at general users? For example will the wallet be developed to make automatic cross chain transfers with other public chains? Another issue the community is concerned about is the currency issuance. Currently there are more than 100 million WAN circulating, what about the rest, when will it be released?
Lini: As a cross-chain public chain, we are not biased towards professional developers or ordinary developers, and they are all the same. As mentioned above, we provide a platform as infrastructure, and everyone is free to develop applications on us.
For example, if it is a decentralized exchange, it must be for ordinary users to trade on; if it is some kind of financial derivatives product, it is more likely to be used by finance professionals. As for cross-chain wallets which automatically exchange, I’m not sure if you are talking about distributed exchanges, the wallet will not be “automatic” at first, but you can “automatically” redeem other tokens.
Finally, the remaining WAN tokens are strictly in accordance with the plan laid out in the whitepaper. For example, the POS node reward mentioned above will give 10% of the total amount for reward. At the same time, for the community, there are also rewards for the bounty program. The prototype of the DEX that I just saw is a masterpiece of the overseas community developers, and also received tokens from our incentive program.
Neutrino community member’s question: There are many projects in the market to solve cross-chain problems, such as: Cosmos, Polkadot, what are Wanchain’s advantages and innovations relative to these projects?
Lini: As I mentioned earlier, Cosmos and pPolkadot all proposed very good solutions in theory. Compared with Wanchain, I don’t think that we have created anything particularly unique in our theory. The theoretical basis for our work is cryptography, which is derived from the academic foundation of scholars such as Yao Zhizhi and Silvio Micali. Our main strong point is that we have taken theory and put it into practice..
Actually, the reason why people often question whether a blockchain project can be realized or not is because the whitepapers are often too ambitious. Then when they actually start developing there are constant delays and setbacks. So for us, we focus on completing our very solid and realizable engineering goals. As for other projects, we hope to continue to learn from each other in this space.
Neutrino community member Amos from Huobi Research Institute question: How did you come to decide on 21 storeman nodes?
Lini: As for the nodes we won’t make choices based on quantity alone. The S in the POS actually also includes the time the tokens are staked, so that even if a user is staking less tokens, the amount of time they stake them for will also be used to calculate the award, so that is more fair. We designed the ULS (Unique Leader Selection) algorithm in order to reduce the reliance on the assumption of corruption delay (Cardano’s POS theory). which is used for ensuring fairness to ensure that all participants in the system can have a share of the reward, not only few large token holders.
Wu Di, a member of the Neutrino community: Many big exchanges have already begun to deploy decentralized exchanges. For example, Binance, and it seems that the progress is very fast. Will we be working with these influential exchanges in the future? We we have the opportunity to cooperate with them and broaden our own influence?
Lini: I also have seen some other exchange’s DEX. Going back the original point, distributed cross-chain nodes and centralized ones are completely different. I’m guessing that most exchanges use a centralized cross-chain solution, so it may not be the same as the 21 member Storeman group of Wanchain, but I think that most exchanges will likely be using their own token and exchange system. This is my personal understanding. But then, if you are developing cross chain technology, you will cooperate with many exchanges that want to do a DEX. Not only Binance, but also Huobi, Bithumb, Coinbase… And if there is anyone else who would like to cooperate we welcome them!
Neutrino community member AnneJiang from Maker: Dai as the first stable chain of Wanchain will open a direct trading channel between Dai and BTC. In relation to the Dai integration, has any new progress has been made on Wanchain so far?
Lini: DAI’s stable currency has already been integrated on Wanchain. I just saw it yesterday, let me give you a picture. It’s on the current 3.0 browser, https://www.wanscan.org/, you can take a look at it yourself.
This means that users with DAI are now free to trade for BTC, or ETH or some erc20 tokens. There is also a link to the Chainlink, and LRC is Loopring, so basically there are quite a few excellent project tokens. You may use the Wanchain to trade yourself, but since the DEX is not currently open, currently you can only trade with friends you know.

Tron: Rising Dragon in blockchain

Have you heard anything about Alibaba, Jack Ma, Tim Draper, Ripple, JP Morgan? ..
Why am I asking this? Recently I discovered an interesting blockchain project from China. Since I have just returned from China, where I promoted innovative technologies, I was amazed by the scale of the changes taking place in the country and now my focus is primarily on this market.
So, the project is called Tron (www.tronlab.com) and it has an ambitious goal that can not be described in two words. I'll try to list:
1) to replace game currencies with the project's crypto currency - Tronix (TRX). Unlike gaming currencies, this currency will be "real", it has real market value. What is the advantage? According to the idea, all projects connected to the Tron ecosystem will use the common currency Tronix or tokens based on the Tron protocol, which can be freely exchanged for Tronix (TRX). This will allow you to freely move assets between different games and applications.
Imagine, you played in Call of Duty, bought there weapons, then some amount left. Later you decide to play Fifa 201x. Move the existing TRX from Call of Duty to Fifa and buy Messi ;) Then go to the social network and buy a virtual gift to someone for the same TRX, open the online cinema and pay for the movie... And all this quickly, safely, conveniently.
2) integrate the TRX crypto currency into the online entertainment industry, which includes not only games, but also social networks, dating sites, etc. This will allow you to enter the premium group, vote for your favorite entries, present virtual gifts. And these are not just plans, but a working model. The first application, which integrates the TRX crypto currency, is Peiwo with an audience of 10 million users. For comparison, according to the evaluation of experts there are about 20 million Bitcoin owners in the world.
3) use its own mainnet blockchain and protocol for the online entertainment industry. At the moment, the TRX crypto currency is a token on the ERC20 protocol. What will it give? Companies will be able to conduct ICO on the basis of the Tron platform and protocol, which will lead to an increase in the value of TRX's internal crypto currency. One of the main disadvantages of Ethereum is the lack of a hard cap, that is why the system requires constant external funding to maintain the value of the ETH crypto currency. At the same time, the TRX has the same advantages as the ETH but has a hard cap of 100 000 000 000 TRX, with a circulation supply of 65 000 000 000. Many investors in crypto-currencies are concerned about such high circulation supply, but this has its advantages. First, the online games market alone exceeds 100 billion dollars. And this is only a small part of the online entertainment market. For example, in China I was surprised to see how pretty Chinese woman earned more than $ 50 in the form of tips just for eating her dinner on the air in the video-streaming app... And gamers who demonstrate in real time how to play DOTa earn several thousand dollars per month.
Thus, such a circulation supply even with the current development of online entertainment will quickly disperse and there will soon be an increased demand for TRX, which will lead to a steady increase in the price of TRX. For example, at the time of writing, TRX costs about $ 0.0024 (0.0000082ETH). If each user of the Peiwo application purchases 6500 TRX (which is only $ 15.6), then there will already be a deficit of tokens. But most importantly, among investors there are such people as Binshen Tang, the owner of the game Clash of Kings with an audience of 40 000 000 people.
Secondly, there are rumors that the Chinese authorities are considering the prohibition of buying and selling the fractions of cryptocurrencies, so you can not buy 0.5 BTC, but only 1, 2 ... BTC to limit the circulation of crypto-currencies. Such circulation supply of TRX will allow free trade on exchanges with these restrictions. In addition, it will allow you to carry out micropayments, such as watching a few minutes of a movie and pay some cents in TRX.
4) create a decentralized data warehouse based on p2p technologies. This means that the content will be the property of authors, not for example of such services as Facebook, Youtube or Google. In other words, users will pay to the authors directly. To date, the authors receive small earnings from the sale of advertising by these services. In addition, it will ensure the constant availability, permanence and reliability of the information, as it will be stored in the blockchain.
My experience of work with innovative technologies showed that the most important thing in the success of the project is his team. And with this, Tron is all right.
CEO of Tron Foundation is Justin Sun, the former representative of Bitcoin settlement platform Ripple in China. Ripple is now the third cryptocurrency by market cap after Bitcoin and Ethereum. It is used for transactions between banks, like SWIFT.
He was awarded by the next titles:
He founded Peiwo, an app aspiring to become China's Snapchat.
Justin Sun was the student of Jack Ma (Alibaba) at Hupan University. Now he is in the Tim Draper’s University.
Recently to a team of more than 60 people, including experts in p2p and blockchain technologies, joined the senior expert Lucien Chen from Alibaba and Tencent (Wechat app).
So, what about investors? Among them are:
Separately, it should be noted that Justin Sun is a protégé of Jack Ma and teaches a course about blockchain technology at his university. In addition, Jack Ma in his recent interview noted that in the future the society should be healthy and happy. Entertainment brings happiness, so it will be part of Alibaba's business.
There are also rumors that Tim Draper invested in Tron. Tim Draper was one of the first to invest in Tesla, Skype, Baidu (Chinese Google).
Lately Justin Sun tweeted that Fund that supported Ripple and some Hedge Funds invested in Tron Foundation.
And some background information.
ICO from Tron passed in several stages from the second half of August to the beginning of September. The price of 1 TRX during the ICO period was 0.00000488 ETH.
A few interesting facts about the ICO Tron. The stage that was held at the Binance exchange was successfully completed in 39 seconds!!! This heated the interest of investors and at the next stage, which was conducted on another site, the desire of investors to get tokens as quickly as possible led to a system’s crash, such a powerful was "ddos attack". In total, according to preliminary estimates, during the ICO about $ 60 million was raised.
Total supply of TRX is 100 000 000 000, circulation supply is 65 000 000 000. The number of decimals is 6. By coin market cap at present TRX is between the 30th and 40th place among all cryptocurrencies.
At the time of writing, TRX traded on the exchanges HitBTC, Liqui, Qryptos, EtherDelta. Some more exchanges on the way, one of which is Korean and another is Australian coolcoin.com. To see TRX in Etherdelta you have to choose to Add custom token and fill the next data:
Address: 0xf230b790E05390FC8295F4d3F60332c93Bed42e2
Token Symbol: TRX
Decimals: 6
And the most pleasant thing is, until October 30, 2017, you can still buy TRX to get a free 10% airdrop after this date.
