On Tuesday, Ethereum (ETH) developer Tim Beiko tweeted that Kiln successfully completed an Ethereum merge with validators that create post-merge blocks containing transactions. Kiln will be the last Merge testnet (formerly Ethereum 2.0) before upgrading existing public testnets. “Merging” involves taking the Ethereum execution layer from the existing Proof of Work layer and merging it with the consensus layer from the Beacon chain, turning the blockchain into a Proof-of-Stake network. Foundation writes:
“This merger marks the culmination of six years of R&D on Ethereum and will result in a more secure network, predictable block times, and a 99.98%+ reduction in power consumption when it is released on the mainnet later in 2022.”
However, not everything seems to have gone according to plan during testing. According to Kiln Explorer, there were several bugs with the creation of the contract. In a follow-up tweet, Beiko reported that the client did not produce blocks consistently, although “the network is stable and more than 2/3 of the validators exit gracefully.” Another Ethereum developer, Marius van der Weijden, also commented on this issue, pointing out that Prysm offered bad blocks during the transition to Kiln.
Prysm is a variant of the Go programming language for implementing the Ethereum Consensus specification. According to Van Der Wiyden, one block turned out to have the wrong base gas charge, and replacing it with the actual expected base value appeared to have resolved the issue. 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 withdraw staked ETH, will not be available immediately after the merge, as the developers are concentrating their efforts on the latter.
And it seems to have worked. Merge blocks are created by validators and they contain transactions! https://t.co/xearnsuZFp Waiting for completion https://t.co/BEfJOI4qqj pic.twitter.com/c4p1UXB5vw — Tim Beiko |timbeiko.eth (@TimBeiko) March 15, 2022
