Transaction data processing method and device based on block chain, and electronic equipment

Abstract

The invention discloses a transaction data processing method and device based on a block chain and electronic equipment. According to the method provided by the embodiment of the invention, the token identifier is added to each piece of transaction data, the token identifier is written into the first linked list according to the monotone increasing mode, the transaction price is written into the second linked list, and the mapping relationships between the transaction data and the first linked list and the second linked list are established based on the mapping relationships; therefore, unified maintenance of the transaction data of different transaction prices is realized through the mapping relation, and the complexity of transaction realization is reduced. In addition, the priority of the transaction data in the processing process is determined through the monotonically increasing token identifier, and the processing flow is simplified. And finally, the transaction hash map is constructed by using the mapping relationship, and the transaction data, the transaction price and the token identifier are stored in the form of the hash map, so that the storage mode of the transaction data in the existing block chain is improved, implementation and management are facilitated, and readability is high. In the transaction data processing process, traceability is achieved.

Description

Technical field [0001] This application involves the field of blockchain technology, especially a blockchain -based transaction data processing method, device and electronic equipment. Background technique [0002] One way is to put all transactions on the contract itself, and each trading quotation maintains a map [(Double, Tradetype), ArrayList]. Among them, Double is a trading price, tradetype storage transaction type. At each quotation, the corresponding price queue is matched. Another method is to establish an application layer on the upper layer of the blockchain. After completing the transaction matching of the application layer, send it to the blockchain to complete the transaction. [0003] In the process of realizing the invention, the inventor found that the first method of the above method became larger as the amount of data, and MAP would slow down with the data of the contract. The time complexity is high. According to the storage characteristics of the blockchain, ...

Problems solved by technology

[0003] In the process of implementing the present invention, the inventors found that as the amount of data increases in the above-mentioned first method, the map will expand with the data, and the contract execution speed will slow down. If there is a rollback operation, the data movement involved in the array operation is relatively large. The time complexity is high. According to the storage characteristics of the blockchain, a large amount of useless data redundancy will be generated, and the complex load on the blockchain will be large.

The second method makes the complete core steps of the transaction complete offline, making the transaction opaque and losing fairness
