Data processing method and device and block chain core distributed system

Abstract

The application provides a data processing method and device and a block chain core distributed system. The method includes the following steps: marking each hotspot transaction instruction in a hotspot transaction instruction set as a hotspot capital outflow instruction or a hotspot capital inflow instruction, wherein the hotspot capital outflow instruction refers to the transfer of capital from a hotspot account to other accounts, and the hotspot capital inflow instruction refers to the transfer of capital from other accounts to the hotspot account; decomposing the hotspot capital outflow instruction into a single-account capital outflow sub-instruction and a multi-account capital inflow sub-instruction; decomposing the hotspot capital inflow instruction into a single-account capital inflow sub-instruction and a multi-account capital outflow sub-instruction; grouping a single-account capital outflow sub-instruction, a multi-account capital inflow sub-instruction, a single-account capital inflow sub-instruction and a multi-account capital outflow sub-instruction belonging to the same hotspot account as a sub class set; and when verifying that all sub-instructions in a sub class set are legitimate, packaging the sub-instructions in the sub class set and writing the sub-instructions into a block of a block chain. The efficiency of data processing is improved.

Description

technical field

[0001] The present application relates to the technical field of financial transactions, in particular to a data processing method, device and blockchain core distributed system. Background technique

[0002] Traditional financial accounting systems mainly use transaction mechanisms to ensure strong data consistency. Among them, strong data consistency means that the transaction submission is completed at one time, either the business in the transaction succeeds, or the business in the transaction fails (rollback). As the core system of the financial account system, the blockchain core distributed system needs to face various performance problems in high-frequency financial exchange scenarios. Among them, the processing of hot accounts is one of the key elements of performance problems.

[0003] The current processing method for hot accounts is assuming that within 1 second, there are a total of 2,000 funds transferred from business account A (hereinafter re...
