The Ethereum community is celebrating the latest step for ‘the merge’ to a proof of work consensus, which included testing on Kiln.
Ethereum developer Tim Beiko announced on Twitter that post-merge blocks were being produced and validated which contained transactions.
The Kiln testing will be the final stage of testing before all testnet versions on Ethereum merge to proof of work. The big shift from proof of work to proof of stake consensus has been long in the making.
The Ethereum Foundation celebrated this recent testnet phase by tweeting: “This merge signals the culmination of six years of research and development in Ethereum and will result in a more secure network, predictable block times, and a 99.98%+ reduction in power use when it is released on mainnet later in 2022.”
There was one minor issue during the Kiln testing – according to some of the community contributors, some of the clients were not able to produce blocks.
The issue was only minor due to the network being stable and more than 66% of the validators correctly finalizing blocks. The issue has since been patched and the Ethereum Foundation was quick to thank the community for finding the issue quickly.
The full launch of Ethereum 2.0 is still set for the second quarter of 2022. Those who have staked Ethereum into the new chain will still need to wait before withdrawal becomes available. Users who hold Ethereum will not need to do anything once the merge is complete.
Leaving proof of work consensus will be a massive step for Ethereum 2.0. The largest critics to blockchain technology stem from the amount of energy required to maintain a proof of work network.
Proof of stake on the other hand has a much lower energy and hardware requirement to run. There are a few blockchains in existence that are already running on proof of work but a switch for Ethereum will instantly make it the largest blockchain running this consensus.
Proof of Work consensus was recently under fire within the European Union. A recent bill was up for vote that would limit or regulate miners for Proof of Work blockchains. The vote did not pass which was a relief for Ethereum and Bitcoin enthusiasts in Europe.
