To this end, Ethereum has set four stages: frontier, homeland, cosmopolitan, quiet, and we are currently in the metropolitan stage, and tranquility is the Ethereum 2.0 we are talking about today. Phase 1 of Ethereum 2.0, also known as Zero Phase (developers like to count from scratch), introduces a consensus layer, and currently 8 teams are implementing the first phase independently, and the beacon chain will be a brand new With the PoS blockchain, users can use the wallet to participate in Staking mining to generate revenue. Phase 2: Fragmentation, the introduction of the data layer, this stage is only a trial run of the slice structure, rather than trying to use the slice to extend the Ethereum. Phase 3: The eWASM virtual machine introduces the executive layer, which will become the familiar Ethereum. At this stage, Ethereum 2.0's important functions are aggregated, the segmentation chain is upgraded, wallet transfers are allowed, and contracts are executed. Stage 4: According to V God, Stage 4 will be the adjustment and optimization of this new world computer.
