The Ethereum ETH -0.67% Foundation released the testnet Sepolia merger announcement. Sepolia is ready for the merger and will transition to the PoS network when the Terminal Total Difficulty (TTD) is 17,000,000,000,000,000, which is expected to happen within a few days.
If no issues are found with the Sepolia merge, Ethereum’s other EL testnet, Goerli, will run through the PraterCL testnet’s Merge once client testing is complete. After Goerli/Prater has successfully transitioned and stabilized, the Bellatrix upgrade on the mainnet beacon chain will select an epoch and set the difficulty value for the mainnet transition.
