The total terminal difficulty — a measure of the cumulative mining difficulty on the Ethereum network — was achieved at block 15537393 at 6:42:42 am UTC today, triggering the transition to proof of stake.
Within just 17 seconds, the first NFT was minted on proof-of-stake Ethereum in the next block. The user paid over 36.8 ETH in transaction fees ($60,626.26) to mint the NFT named “The Transition.” It features an Ethereum panda mascot and is part of a collection of 100 on NFT marketplace OpenSea.
The NFT also shows key details related to Ethereum, including the difficulty level at the time and a timestamp.
The collection now takes its place in Ethereum history, but it’s not the first time the panda mascot has appeared as an NFT, with PandETH minted back in early 2019.
