SOPHON is an "ARC-20 inscription concept coin" deployed on the Bitcoin mainnet. The ARC-20 token standard is provided by the Atomicals protocol, enabling minting and transfer based on BTCs UTXO. Its basic unit, the "atom," is constituted by the smallest unit of Bitcoin, the sat, meaning each unit of ARC-20 token is forever backed by 1 sat, i.e., 1 Token = 1 sat. Additionally, ARC-20 is the first token protocol to mint inscriptions via POW, allowing participants to mine inscriptions/NFTs in the same way they would mine Bitcoin.
