What are the three necessary steps before the permanent migration of Ethereum (ETH) to proof of stake?


According to the lead developer ofEthereum, Tim Beikothe road to the full transition from the current Ethereum (ETH) “mainnet” to the beacon chain’s Proof-of-Stake (PoS) system, a process also known as “The Merge”, is now clearly in sight.

In a recent blog post, Beiko detailed the steps that need to be taken before the world’s second largest crypto project migrates to PoS.

First, Ethereum needs to have a “small number of Shadow Forks on the mainnet running smoothly.” As noted, Ethereum developers set up the first-ever shadow fork in early April, which was designed to test developer assumptions against existing testnets and the mainnet.

The developer Marius van der Wijdenwho is at the origin of the idea of the shadow fork, called the first shadow fork a “huge success”. However, he also noted that there were some significant issues.

For example, Netherminda provider of Ethereum-based software systems, and Besu Hyperledgeran open-source Ethereum client based on Java, ceased to function during the transition. There was also an issue with the default gas limit.

While the first shadow fork caused some problems, “the second mainnet shadow fork (MSF2) went almost without complications,” Beiko said, adding that.

If MSF3, another upcoming shadow fork, “runs smoothly and remains stable thereafter, we may move on to upgrading existing testnets.”

Once the network has passed a number of “shadow forks”, it will be time for Ethereum clients – the software needed to enable Ethereum nodes to read blocks on the blockchain and Ethereum-based smart contracts – to move on. different series of fusion tests.

The first test suite is called Winter. Its purpose is to test the engine’s new Application Programming Interfaces (APIs) that different customers use to communicate. In addition to improving Hive, developers will work with Kurtosisan end-to-end testing platform for critical blockchain infrastructure, to “find implementation issues between clients and monitor various network health metrics.”

Besides these two, there is also a long list of tools built by the customer, research, and testing teams to help developers identify potential issues. These include fuzzers, bad block generators, debugging APIs, and more.

The third and final step will be the deployment of “The Merge” on the existing public testnets, namely Ropsten, Goerli and Sepolia. As public testnets require broader coordination within the Ethereum ecosystem, they would be a final requirement before setting a merger date for the mainnet.

“And that’s it! Once these processes happen, and we’ve observed them to be stable for a few weeks, we’ll be ready to go mainnet!” Beiko said.

It should be noted that there is no specific date for the merger yet. However, Beiko said in mid-April that the network upgrade would likely be completed a few months after June.

“There is no firm date yet, but we are definitely in the final chapter of the [preuve de travail – PoW] on Ethereum,” Beiko wrote on Twitter at the time.
