ETHS is considered the first "concept coin" of the Ethereum inscription protocol, Ethscriptions. ETHS is the first "Ethereum inscription concept coin" deployed on the Ethereum mainnet, with subsequent minting rules established by the first minter.
Ethscriptions is similar to the Ordinals protocol on Bitcoin, allowing 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.
