ETH 2.0 Phases

So, how will ETH 2.0 be rolled out since it is full of so many improvements? The answer is in phases. At least three phases to be more precise; Phases 0, 1, and 2. Phase 0 will launch in 2020, with Phases 1 and 2 releasing in the following years.

Phase 0

The Beacon Chain will be implemented in this first phase and will execute the POS consensus mechanism that we’ve been discussing. The original PoW chain will continue to run alongside the new PoS chain to ensure there is no break in data continuity.


Phase 1

There is no firm launch date for Phase 1 yet, but it will likely roll out in the year following the launch of the Beacon Chain. The primary improvement of this phase will be the implementation of shard chains.


Phase 1.5

In Phase 1.5, the two blockchains (PoW and PoS) will merge to ensure continuity and one single Ethereum network. Though the history of the original PoW chain will still exist, it will operate like any other PoS shard on ETH 2.0.
ETH holders need not fear as they will not have to undergo any sort of token swap. They will be able to use their old ETH on ETH 2.0.


Phase 2

Although less defined than the previous phases, with both PoS and sharding, successfully implemented, Phase 2 will enable such things as ether accounts, transactions, transfers and withdrawals, and smart contract execution.


Beyond Phase 2

ETH 2.0 has long been anticipated and the Ethereum blockchain will not be done with its evolution after Phase 2. The years following Phase 2, promise to be more exciting and filled with more opportunities for sure.
