This application claims the priority of a Chinese patent application filed with the Chinese Patent Office on August 20, 2019, the application number is 201910770184.2, and the invention title is "a transaction processing method and related equipment", the entire content of which is incorporated into this application by reference in.

Technical field

This application relates to the field of blockchain technology, in particular to a transaction processing method and related equipment.

Background technique

Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of data blocks that are generated using cryptographic methods. Each data block contains a batch of Bitcoin network transactions. Information, used to verify the validity of the information (anti-counterfeiting) and generate the next block.

In blockchain technology, Token refers to a kind of tokens, points, tokens, etc., issued through smart contracts in the blockchain, which can be circulated in the blockchain ecosystem. When circulating, generally Tokens can be regarded as tokens, such as Bitcoin, Ethereum, etc. In the current blockchain system, the token is the asset proof for the user’s transaction. There are two main types of record storage methods, namely the unused transaction output (UTXO, Unspent Transaction Output) mode and the Account mode. At that time, the system calls smart contracts through blockchain nodes to perform transactions on each, and the number of issuances and inflation rates are specified in the smart contract code. Token often has the characteristics of exchange, and the process of token exchange between different users is also carried out in the token contract (the contract records the token balance of each user).

However, in the prior art, a smart contract corresponds to a token. In addition, when the same user creates multiple accounts in the same blockchain system to perform transactions, the token information is completely recorded in the contract, which makes subsequent transactions to the token All operations require the use of special smart contracts to call, and different smart contracts may be called in different ways, and the interfaces are not uniform. As a result, the smart contract must be called multiple times to connect with the blockchain system and repeated login verification is required. Transactions can be carried out, making the user's transaction process in the blockchain too cumbersome, thus affecting the user experience.
