This paper presents a protocol for scaling the creation, management, and trading of non-fungible tokens (NFTs) on Bitcoin by extending bridgeless minting patterns previously used on other blockchains. The protocol leverages on-chain Bitcoin data to handle all aspects of token ownership, including trading, while integrating a secondary consensus system for minting and optionally modifying token metadata. To minimize its on-chain footprint, the protocol utilizes the OP_RETURN mechanism for ownership records, while complementary NFT-related actions are stored on the LAOS blockchain. All data remains permanently on-chain, with no reliance on bridges or third-party operators.
