Merge trials on testnets are essential to allow Ethereum developers and independent project developers to understand what they can expect when the actual Merge takes place.
Ethereum has now completed its second-to-last major Merge trial on the public test network Sepolia, paving the way for its transition to the proof-of-stake (PoS) consensus mechanism.While it's been judged mostly a success, it was not incident free.The final trial of the Merge is set to occur on the Goerli network over the next few weeks before the official Merge on the Ethereum mainnet can be given the go ahead.
