On Tuesday, Ethereum developer Tim Beiko tweeted that Kiln went through the process of merging Ethereum with validators creating post-merge blocks containing transactions. Kiln will be the last integration testnet, formerly known as Ethereum 2.0, before the existing public testnets are upgraded. The “merger” involves taking the Ethereum implementation layer from the existing Proof of Work (PoW) layer and integrating it with the Beacon chain consensus layer, turning the blockchain into a Proof of Stake (PoS) network. The company writes:
“This merger marks the culmination of six years of Ethereum research and development and will result in a more secure network, predictable block times, and 99.98%+ energy savings when it is deployed on the mainnet later in 2022.”
However, it looks like not everything went according to plan during testing. According to Kiln Explorer, there were several bugs related to node creation. In a follow-up tweet, Beiko said that one client did not always produce blocks, although “the network is stable and more than two-thirds of the validators executed correctly.” Another Ethereum developer, Marius van der Weijden, also commented on this issue, noting that Prysm offered bad blocks during the transition to Kiln.
Prysm is a variant of the Go programming language for implementing the Ethereum compatibility specification. As van der Weyden said, it turns out that the block has the wrong base tax for each gas value, and replacing it with the actual expected base value seems to have solved the problem. In its official roadmap, the Ethereum Foundation states that the Merge update will be released by the end of the second quarter of 2022. However, some features, such as the ability to mine ether (ETH), will not be available immediately after the merger, as the developers focus on the latter.
