Proof of Stake

This commemorative coin celebrates Ethereum's historic transition from proof-of-work (PoW) to proof-of-stake (PoS). One hundred coins will be minted in total. Initially, the coins will be displayed with the PoW side up. After The Merge happens, owners will have the option to flip their coins to PoS via a function in the smart contract. Bear in mind that flipping is irreversible! Oh, and there's a 1 ETH reward for the first flipper 😉.
