The Sepolia Beacon Chain testnet has gone live, setting the stage for its merge dress rehearsal to give developers an insight into what may happen when the Ethereum mainnet performs its merge. Sepolia Beacon Chain Testnet Goes Live Ethereum client Nethermind tweeted that the Sepolia Beacon Chain is deployed and Ethereum’s 2nd public testnet chain merge is just around the corner. Aaaand it's live 🚀 Sepolia Beacon chain is deployed Ethereum's 2nd public testnet chain-merge is just around the corner!#theMerge pic.twitter.com/Sw8lUuJ7y9 — Nethermind (@nethermindeth) June 20, 2022 Upon merging with its dedicated Beacon Chain, the Sepolia testnet will reach a consensus using Proof-of-Stake (PoS) rather than Proof-of-Work (PoW) to perform test trials. The exact date of the Sepolia merge, however, has not been revealed. Testnet merges enable developers using the Ethereum network to understand what they can expect when the actual merge takes place. Just like on the testnets, the Ethereum mainnet merge will see the entire network transition to PoS consensus and should reduce the energy consumption of Ethereum by 99.9%. Ropsten Replaces Sepolia Back in April, Core Ethereum developer Tim Beiko tweeted that the Ropsten testnet would be phased out over time and replaced by Sepolia. Therefore, projects running apps on Ropsten should move over to Sepolia to avoid complications. So, if you are using the network, we recommend moving to either ...
