The Ethereum Merge has officially taken place, marking the full transition of the network to proof-of-stake (PoS).
On Sept. 15 at 06:42:42 UTC at block 15537393, the long-awaited Merge saw the merging of the Ethereum mainnet execution layer and the Beacon Chain’s consensus layer at the Terminal Total Difficulty of 58750000000000000000000, meaning the network will no longer rely on a proof-of-work (PoW) consensus mechanism.
