Just a few days after the Ethereum founder Vitalik Buterin told about the Protocol Serenity and the future of Ethereum to the conference Devcon4, four crypto-researchers completed and published a draft white paper technology Casper designed to scale the blockchain for the second larger cryptocurrencies by means of a consensus Proof-of-Stake (PoS).

As explained by the lead developer of Ethereum Foundation Vlad Zamfir on Twitter, they have developed the technical documentation under the title “a Family of consensus protocols for the minimum implementation of CBC Casper”.

The document contains a number of technical details and describes the decentralized consensus mechanism/Protocol that allow to efficiently integrate the PoS algorithm in Ethereum network that for a long time remains a priority for developers.

Since the white paper CBC Casper is currently represented only in schematic form, implementation of technologies in the core network cryptocurrency roughly may take another 2-3 years.

Talking about the process of transition to Serenity and 2.0 Ethereum, Vitalik Buterin described three phases, including “the true realization of Casper”, which will allow networks first to jump on the hybrid mechanism of consensus is PoW/PoS and then pure PoS. It is expected that the end result of this process will be to increase the scalability of blockchain Ethereum 1,000 times, that will answer some of the most pressing short and medium term problems of the system.
