The Goerli testnet was successfully merged to the proof-of-stake (PoS) network, marking the final step before Ethereum’s mainnet transition. The triumphant final testnet merger means the mainnet transition slated for Sept. 19 could go as scheduled.
Goerli is the third and final testnet after Ropsten and Sepolia that makes Ethereum's final rehearsal before its official transition to the PoS network.
