Abstract

The invention belongs to the technical field of block chains, and discloses an NFT transaction method, an NFT transaction system, a computer readable storage medium and terminal equipment. The transaction method comprises the steps that: the transaction output of UTXO is limited as unique transaction output; NFT and an UTXO are set to be in a one-to-one mapping relation, and the TXID of the UTXO is published to a public channel; an NFT sender adds an NFT receiver as an unlocking script opener of the UTXO, creates a new UTXO and sends the new UTXO to the NFT receiver; the NFT sender sends a transaction chain between the latest UTXO corresponding to the NFT and all the spent transaction outputs to the NFT receiver; the NFT receiver carries out local tracing upwards through the latest UTXO transaction input; the NFT sender sends a block header where the UTXO corresponding to the NFT is located and a Merkel proof to an NFT payee; and the NFT payee performs local legality verification through the block head where the UTXO is located and Merkel proof. According to the method of the invention, issuing, circulation, traceability and legality verification of the NFT are realized, and the whole process is simple and efficient.

Description

technical field [0001] The present invention relates to the technical field of blockchain, and in particular to an NFT transaction method, a transaction system, a computer-readable storage medium, and a terminal device. Background technique [0002] Tokens or crypto tokens (in the context of blockchains) are unique virtual tokens representing digital assets on each blockchain. Encrypted tokens are divided into two categories, namely, fungible tokens and non-fungible tokens. Fungible tokens are the same, meaning that one token has exactly similar characteristics to another token, as long as they are called the same name; non-fungible tokens (NFTs) are different , indicating that no NFT has a function similar to the others. [0003] Non-homogeneous tokens (NFT) have the following characteristics: (1) Standardization: NFT has some standardized functions, including ownership, transfer, etc. All non-fungible tokens have these functions. Any developer can take advantage of thi...
