Abstract

The invention relates to a block chain data synchronization method and system based on data fingerprints, and the method comprises the steps: recognizing business fields in an incremental updating record, sorting the business fields according to a preset logic, removing empty business fields to obtain non-empty business fields, splicing the non-empty business fields, and converting the field values into data of a preset format type; reordering the data of the preset format type, and splicing to generate a fingerprint original text; the method comprises the following steps: performing operation on a fingerprint original text to generate a record fingerprint, if the record fingerprint changes, updating the fingerprint to a data table of an incremental update record one by one, and synchronizing the corresponding incremental update record to a block chain, through the application, the problem that a large amount of repeated data or invalid data synchronization exists in block chain data synchronization is solved, and the user experience is improved. According to the method, a large amount of invalid data to be synchronized is removed based on data identification and data fingerprints, and synchronization of invalid data is reduced in a block chain data synchronization scene, so that the data synchronization efficiency is improved.

Description

technical field [0001] The present application relates to the field of blockchain technology, and in particular, to a method and system for synchronizing blockchain data based on data fingerprints. Background technique [0002] At present, there are more and more application scenarios based on blockchain, especially in transaction scenarios. In the big data scenario, data synchronization based on the underlying technology of blockchain is a relatively new research direction, but it also faces many problems that need to be solved urgently, such as the problem of a large amount of data duplication or invalid update of data is one of them. [0003] These duplicate or invalid data can be inherently out of sync simply because the daily update of the model refreshes the timestamp or the model writes the same result data to the record. This type of data occupies a large amount of data update, occupies a large amount of data synchronization bandwidth, and also prolongs the data syn...
