On Tuesday, Ethereum (ETH) developer Tim Beiko tweeted that Kiln successfully passed the Ethereum Merge, with validators producing post-merge blocks containing transactions. Kiln will be the last Merge testnet (formerly Ethereum 2.0) before existing public testnets are upgraded. "Merge" involves taking Ethereum's 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.

However, it appears not everything went according to plan during testing. According to Kiln Explorer, there were several errors relating to contract creation. In a follow-up tweet, Beiko said a client was not producing blocks consistently, though "the network is stable, with >2/3rd of validators correctly finalizing." A fellow Ethereum developer, Marius Van Der Wijden commented on the matter as well, pointing out that Prysm was proposing bad blocks during the transition on Kiln.
