In December last year, the Creator of Ethereum, Vitalik Buterin published its proposal on how to accelerate the launch of Ethereum 2.0 – a new version of the Ethereum blockchain for Proof-of-Stake (PoS).
In his article Buterin described the concept of “customer no status” (stateless client) is a method that changes the way storage account balance, the code of the smart contract and other information in the Ethereum network. Information about the client verifierade through a mathematical proof without saving all the data in the blockchain. In other words, Ethereum 2.0 should be more “easy”.
“In fact, customers perform the same check as usual, except that they do not retain state,” said Buterin in an interview with CoinDesk. “The network simply records the status in real time and verifies it using the Merkle proof”.
Leading project developers recently announced plans to launch Ethereum 2.0 this year. As part of the transition from the blockchain for Proof-of-Work (PoW) known as Eth 1.x Buterin and Ethereum Foundation offered to run the current network on the “frame” of the blockchain of Ethereum 2.0, until the latter is fully operational. In this case, Eth 1.x will exist as a giant set of transactions to complete the transition to 2.0.
“You can copy the state [Eth 1.x] and run it inside another blockchain Proof-of-Stake,” said Buterin. “The balance of the account and all apps continue to work, but the blockchain Proof-of-Work, as we know it today, will disappear. And there would be two separate blockchains: transaction 1 Eth.Eth 2.0 x and will be in the same block”.
