The Ethereum 2.0 project has gathered around itself not only adherents. Skeptics are still trying to find vulnerabilities in the updated version of the protocol. To reduce the degree of criticism, the developers of the project announced the creation of a group to solve cybersecurity problems. Network security comes first The release of the Ethereum 2.0 project has already repeatedly postponed due to the identification of technical errors during system testing. A cautious approach to the launch of the updated protocol is fully justified since this project has promising prospects for changing blockchain technology. On the agenda of the development team is the question of modernizing the network cybersecurity system, introducing technical solutions that will solve the problem of user data vulnerability to hacker attacks. For this purpose, the Ethereum Foundation announced the creation of a separate project team. Justin Drake, one of the Ethereum 2.0 team members, tweeted about seeking specialists for the security and auditing department of the software product. The developers announced the launch of testing of the Ethereum 2.0 network using faying. This method assumes the most comprehensive audit of the program code, identification of errors at an early stage of the product launch, and their prevention in the future. The developers claim that the use of fizzing will help create a cyber-resistant network ecosystem. Also, the new team will develop an algorithm for modernizing the security system in a scalable project. Although some technical experts question the transparency of the transition of users to the updated blockchain, the development team argues that the Ethereum 2.0 engine will be convenient for validators. Why Ethereum 2.0 lends itself to criticism? Skeptics are not convinced that the new blockchain will be completely secure for users, despite the statement of its developers. The question of the algorithm for freezing and unlocking tokens on the platform during the high volatility of the cryptocurrency remains a “blind spot” so far. It is also not yet known how the transition to the Ethereum 2.0 blockchain will take place to eliminate the risk of losing or blocking assets. Some experts believe that the launch of Ethereum 2.0 is a “game for a long time”, so it makes no sense to count on the next release of the project. Despite some skepticism within the crypto community, Ethereum creator Vitalik Buterin convinced that the updated protocol will realize at the end of 2020.
