After Ropsten, the Sepolia testnet is next in line for a merge trial run, as its Beacon Chain is now live and ready to provide developers with valuable information in the run-up to the real thing. As such, the Sepolia testnet shall begin reaching consensus using PoS rather than PoW after merging with its dedicated Beacon Chain. However, the precise date of Sepolia has yet to be confirmed and further delays are expected due to the difficulties concerning ETH 2.0. Testnet merges are necessary for Ethereum developers as well as independent project developers who use the Ethereum network to recognise what to expect when the complete merge occurs. The Ethereum mainnet merge, like the testnets, would therefore involve the entire network finally transitioning to PoS consensus, which is reportedly being said to ultimately reduce Ethereums energy consumption by over 99%.
