FISH is an "Ethereum Inscription Concept Token" deployed on the Ethereum mainnet, with subsequent minting rules established by the first minter.
Ethscriptions, similar to the Ordinals protocol on Bitcoin, allows people to inscribe various types of files onto the Ethereum mainnet, as long as they do not exceed 96KB in size. Specifically, the protocol involves adding a note (in hexadecimal characters) to a transaction, which is then recorded in a block.
