Block chain cross-fragmentation transaction data processing method and device

Abstract

The invention discloses a block chain cross-fragmentation transaction data processing method and device. The method comprises the steps of obtaining transaction data sent by a user, analyzing the transaction data; obtaining an account number involved in the transaction data and determining fragment information corresponding to the account number; according to the fragment information corresponding to the account number, determining a fragment execution table, the fragment execution table comprising a sequence of executing preprocessing by each fragment and a preprocessing time threshold, transmitting and preprocessing the transaction data among the fragments according to the fragment execution table, and determining a processing result of the transaction data according to a preprocessing result and preprocessing time of a consensus node corresponding to each fragment on the transaction data. The transaction data is analyzed to obtain the account number information and the fragment information corresponding to the account number, so that the sequence of executing the preprocessing of the fragments is determined, and then the fragments are sequentially transmitted and preprocessed among the fragments, so that cross-fragment execution of the decentralized transaction data can be realized, and the consistency and the atomicity of the transaction data are ensured.

Description

technical field

[0001] The embodiment of the present invention relates to the field of financial technology, in particular to a method and device for processing cross-shard blockchain transaction data. Background technique

[0002] Blockchain is a new type of decentralized data consensus protocol, which can form distributed data consistency in an environment dominated by no central node. In the existing blockchain system, all nodes need to maintain a complete and full amount of data, so the throughput rate of the blockchain system cannot expand with the increase in the number of nodes. In a high TPS (Transaction Per Second) environment such as electronic payment, the performance of the blockchain is a major bottleneck restricting its application. At present, the main technical means to improve the throughput rate is to process the transaction data in pieces, that is, different transactions are stored on different consensus nodes, so as to reduce data redundancy and improve ...
