I might just be a little dumb, but is there an official announcement, and/or countdown until Ethereum cannot be mined? I can't seem to find anything definitive.
the current consensus algorithm used by Ethereum is Proof of Work, and that the switch to Proof Of Stake will occur in the future eht v2.0.
You can follow the thread shared by the member @zasad because there is no exact date and I think the coming days will be decisive regarding the upcoming update.
