First of all, why ETH 2.0? As you know, the current Ethereum blockchain has a scalability problem that can not process more transactions in a second. This common problem has brought frustrations in ETH holders as most of the time network was seen clogged to claim higher gas fees for the single transactions. ETH 2.0 aimed to offer more scalable, more secure, and more sustainable services to all.
Ethereum "Phase 0" The most anticipated Ethereum 2.0 (Updated version of Ethereum) is live from 12:00 UTC Tuesday, Dec 1. Tuesday's launch of Ethereum 2.0(ETH 2) is known as "Phase 0" of the network that includes a launch of the beacon chain. Remember, ETH 2.0 will be fully upgraded in several phases as shown in the following figure so until then, it will not be fully functional.
If you have some ETH holdings, you need to do nothing as PoS chain of ETH 2.0 is just launched and there is still a long way to be accomplished so that ETH 2.0 will be fully functional.
The steps There are 4 phases which are Phase 0. Phase 1, Phase 1.5, and Phase 2.
At "Phase 0" (PoS), ETH holders can lock ETH to expect block reward.
At "Phase 1", there will be a creation of shard chains (maybe in 2021), and blockchain will allow handling so many transactions.
At "Phase 1.5", is the most important phase at which ETH 1 meets with ETH 2 to replace miners and PoW algorithm and blockchain is expected to be used broadly.
At "Phase 2", existing shards start to execute transactions natively.
Things which personally want to see in ETH 2 Things required to maintain the validator's nodes?
How ETH 2 will allow native ETH to combine a store of value, a capital asset, and a commodity?
So hopefully, ETH 2 will be fully functional in 2022. Some exchange sites like Coinbase and Huobi have already announced to support ETH 2 so wish all the best for ETH 2😊.
