V God: The long-awaited upgrade is "optimistically estimated" to be completed by the end of the year

At the Ethereum Global Summit on the second day, Vitalik Buterin said that as the merger approaches, the roadmap has become more pragmatic in many ways, and the long-awaited upgrade is "optimistically estimated" to be completed by the end of this year.

For the merger, the biggest compromise is that the new Pos chain will not contain the transaction data of the old chain, and the old chain will be named the execution chain. At the same time, the beacon chain that introduces Pos into the Ethereum network will be named the consensus chain. After the merger, the execution chain will be within the consensus chain. He believes that this design is to make the merger simpler and smoother.
