Who has the power to change public blockchain

Way to part with the old code not yet invented. And, although softforce and velvet forks represent a softer alternative to the hard forks, meaning a complete break of relations with the previous bloccano, important changes in the code often accompanied by the split of the community and the conflict of developers. One of the last large-scale criticism of the Ethereum proposal for the return of lost funds (EIP 867) involving «rescue hard forks» in the hacking or blocking of funds, as in the case with Parity. The idea was supported by Vitalik Buterin, whereas on the side of the opponents was made by one of the leading Bitcoin Core developer Gregory Maxwell, who said, «no one should have that power,» keeping in mind that no one shall at its discretion and in the pursuit of their own funds to change the entire blockchain. And after the code editor EIP 867 Yoichi Hirai resigned from his post, acne Buterin held a meeting to discuss the management of Ethereum. In the course of it he noted the complexity of the process, which are suggestions for improvement of Ethereum before being built into the actual framework code. One of the leading developers of Ethereum Greg Colvin noted that team members need to work to ensure that the community understood the essence of the new proposals.

The radical solution provides a Protocol compatibility Polkadot, which picks out the dominant role of the developers and transmits the power over bloccano to holders of tokens. «The proposal to manage — Polkadot — addresses the shortcomings of many existing placenow that zakonchilisi the fact that the community is deadlocked, or undergo continuous forks,» said Peter Saban, Director of the project sponsoring organization Web3 Foundation. The Protocol is headed by the co-founder of Ethereum and Parity Technologies Gavin wood. Collected in October $140 million, Polkadot ICO has become one of the largest in 2017, however, the occasional freezing of funds Parity 6 November and budget of the project. Despite the fact that in early December, CEO Parity Jutta Steiner promised that access to funds will be open after the planned uprgade 4-6 months, trying to recover and reallocate funds to a halt. According to wood, one of the main reasons of this inactivity is the lack of a transparent mechanism to count all «pros» and «cons». «The last difficulty in the management of Ethereum given to understand that, regardless of the behavior of the community is very important to have a clear process for making any custom changes to the Protocol, whether adding new functionality or fix bugs» — said wood.

The need to formalize partly led to the concept of management Polkadot — in the «blockchain of blockchains» every change in Protocol, even minimal, will be followed by a referendum. Released during the ICO internal token platform — DOT — allows holders to vote on each piece of code that needs to be embedded in the blockchain. «This will eliminate any misunderstandings as to what changes are making this offer», — said Saban. Along with voting will run a special consultation, which can block intruders or to recognize the vote invalid if a significant part of holders DOT not participate in it.

Some of this formalized approach was necessary for Polkadot due to its differences from «traditional» blockchains. Is the node network Polkadot consists of different elements, «validators», «appointing», «analysts», «fishermen» — each on his level, ensures network security. And while some of them act as a blockchain-nodes, they are not responsible for making changes. «The validators were not able to block the change with which they disagree,» says wood. According to Sabana, the inclusion of token holders in the voting process was for the most part practical choice: «There are many potential parties that may be involved in the ecosystem, however, the holders of the token is the only one who easily quantifiable,» says Saban, while noting that in the future the amount involved in the adoption of the amendments parties may increase.

During the ICO was sold half of the DOT emission, 30% of tokens moved Web3 Foundation and 20% was left in reserve. Thus, the control network depends on the distribution of tokens and from the appointed Council, which can veto certain changes. In this scheme, the developers are deprived of a monopoly on network management, and developer of Ethereum Vlad Zamfir already expressed doubts about this proposal. «I’m not an expert in management models, but I have enough of looking at this is to completely disagree,» said Zamfir, who last week, during the conference, the Ethereum community EthCC, presented his own not yet completed research on management. As an opponent of «oncein-control» Zamfir says that the automated methods of decision-making take the leading role from the operator node and therefore «are contrary to fact of public blockchains»: «I don’t trust to the holders of tokens and I don’t think they should have a stronger leverage than the other members of the community,» said Zamfir.

However, according to wood, the holders of beneficial token to act for the good of the network. «Holders have a very clear and powerful incentive to do what’s right for your network and that will lead to higher prices. There is also no reason to believe that the operators of nod are experts in changing the Protocol,» said wood.

In addition, the Protocol Polkadot was designed to be easy to implement, and this, according to its creators, will be a major advantage. «This is a very pragmatic proposal that we can implement using what we have now,» says Saban.

Web3 Foundation will also support the next meeting of the developers of Ethereum Magicians to be held in July in Berlin with the participation of Greg Colvin and member of the Ethereum Foundation Jamie Pitts and will focus on finding new ways to make changes to the Ethereum platform. «We’re definitely very interested in a deeper dive into the subject of management,» — said Saban.
