Ethereum 2.0 highlights: new features, launch schedule and how to mine

Ethereum (Ethereum) will be gradually upgraded over the next 3 years, transitioning from 1.0 to 2.0. For the convenience of finding information later, I will directly list the five key points of Ethereum 2.0, and attach the original reference at the end:

1. Two new features: The mining mechanism is changed to Proof of Stake (PoS) to improve the security of Ethereum. Additional sharding technology is added to improve the processing efficiency of Ethereum.
2. PoS not only makes mining more environmentally friendly (less power consumption) but also makes the blockchain more secure, and the distribution of mining rewards will be more even.
3. PoS miners don't have to hold miners, they just need to hold ETH. Users who hold any amount of ETH can participate in PoS mining through wallets or exchanges in the future. It's as simple as staking LikeCoins to validators through Liker Land now.
4. The principle of sharding technology is very complex, but the application is very simple. Without sacrificing security and decentralization, the processing efficiency of Ethereum can be increased to hundreds to thousands of times. This in turn reduces transaction fees on Ethereum.
5. Ethereum 2.0 is expected to be rolled out gradually in three phases by the end of 2022. Phase 0 (expected end of 2020) will open PoS mining. Phase 1 (expected 2021) rollout of sharding. Phase 2 (expected 2022) Ethereum dapps can move to Ethereum 2.0.
