Ethernet Square Lightning Network? Buterin and Poon launch “Plasma” expansion program


nnnAs the world’s second largest block chain platform, the etherflies Square has recently appeared in a series of capacity issues – popular projects for ICO trading stagnation, can not be normal progress. This raises a similar expansion problem with Bitcoin, but there is also a lot of concern in this area, such as sharding, lightning networks and Truebit. But this week released a new solution Plasma has also quickly attracted wide attention, but only the program behind the two names – founder of the tower founder Vitalik Buterin and lightning network author Joseph Poon, is enough to make this Adequate attention.n

nThere is currently a problem that people are trying to ignore: there is no way to support a lot of users.n
nAlthough these limitations were only potential problems discussed by researchers, these problems have now affected real users. The world’s second-largest block-chain platform has recently emerged as a series of capacity issues, including increased smart contract costs, which occasionally lead to stagnation of trading time and disrupt the release of new ICO projects.n
nBut this is not to say that there have been some noteworthy attempts to propose solutions – Sharding, Lightning Network and Truebit, these projects are an innovative way to ensure that the future of the application to the center as we The current use of the central application as easy to run.n
nBut a new solution, PLasma, released on Wednesday, is rapidly rising and perhaps a worthy watch.n
nThis is because the project maker – Vitalik Buterin and Joseph Poon – in the block chain history can be said that others are difficult to match. Not only Buterin is the founder of the ethercom, and Joseph Poon is also the co-author of the Lightning Network White Paper, and has developed a roadmap for this technology, and this technology has been widely considered to be the best of the number of users select.n
nThe two men came together to work together on a scalable project, which is a powerful combination.n
nPoon on CoinDesk said:n
nn”People say you can not put everything in the world on the chain chain, but really, I think it is possible.n
nnHe is convinced that the mission of the company to become a global computer to “replace the server group,” the mission will eventually be achieved, and there is no doubt that these expansion problems will eventually be overcome.n
nPoon said:n
nn”This kind of decentralized application is like a real technician, because there is no clear path and path to show how to achieve.”n
nnBut now with Plasma, he believes that this can be achieved.n

nSub-block chainn
nIn simple terms, this expansion problem is: to view the history of the ether square, users need to get a copy of the entire chain of chains, their own transactions and calculate the history of a complete record. However, a “global computer” requires a lot of data, and most users are obviously unable to store all of these data on their own devices.n
nThus, the Ether Square and other public block chains are looking for ways to reduce the amount of data stored directly in the block chain.n
nPlasma is hoping to do this by using many sub-block chains.n
nThe system connects the “child” block chain with the “main” block chain by something called “fraud proof”. This is similar to the lightning network, Poon as early as two years ago for the bit currency proposed this idea – the top layer of the network layer and the underlying core block chain with each other.n
nAlthough the lightning network is strictly limited to pay for use only, but Plasma will extend this idea to more complex calculations, such as the ethercom smart contract.n
nPoon said:n
nn”Basically, you want to do some mathematical operations; for example, these math operations are very complex and time consuming, then you can call someone else to help you.”n
nnAt this point, someone has proposed a currency “bond” solution, such as $ 10, and that this solution is correct. Users not only believe that the solution is correct, there are still constraints and balance.n
nHe explained:n
nn”Anybody in the world can say, ‘No, you screwed up at step 7’.”n
nnIf the challenger can prove that the initial solution is wrong, then the other person can calculate and identify the error. In addition, if the user suspects that there is fraud, then they can also choose to return to the “main” block on the chain to calculate, so once and for all to resolve the dispute.n
nAccording to Poon, since all participants know that their fraud may be caught and punished, they are unlikely to try to deceive the system.n

nStill criticizedn
nHowever, some people still have doubts about this. This technical idea has been extensively discussed in the chain-chain community and has attracted some strong supporters, but there are also stubborn opponents.n
nEach public block chain agreement will eventually encounter expansion restrictions. The most widely used public chain – Bitcoin is the first block of chain expansion, and then it seems to be faced with endless expansion of the debate.n
nHowever, long-term critics argue that the expansion of the tower is likely to be more apparent because it needs to store a significant amount of data if it becomes a “world computer”.n
nVlad Zamfir, director of research on ether-based equity proof, especially commented on the subject of Plasma. He said in his tweet yesterday, “Frankly, he was not very excited about the project,” and said he had given up a similar project in 2015.n
nDespite this, Poon does not seem to be affected by the negative comments of Zamfir. Buterin is the same, and clarifies that Plasma is a supplement to the existing expansion of the ethertop workshop (sharding, aimed at improving the base layer capacity of the protocol).n
nHowever, Poon also admitted that there is still a long way to go. The idea of ​​becoming a product requires a “mass test”. He once again compared Plasma to the Lightning Network, although it has made significant progress over the past two years, but it is still not over.n
nThe advantage of Poon is optimism:n
nn”I think this will show the real possibility of this program.”n
