Problems solved by technology

If the unstructured data has a master-slave backup mechanism, you may consider trusting the master node data. Even if the master node data is wrong due to external or human factors, the master node data will be copied to the slave node. However, when the master node data has been damaged When, unanimously believe that the master node data will lead to the final data is not the correct data, resulting in data tampering and unreliable data

Abstract

The present application provides a blockchain-based self-repair method for unstructured data, including that the first node initiates a self-repair transaction for the unstructured data file stored by the first node to the blockchain cluster, and the self-repair transaction includes the first The first signature of the node; consensus on the self-repair transaction, if there is a preset number of nodes that meet the requirements of the consensus rules to receive the self-repair transaction, the self-repair transaction consensus is successful; all nodes execute the self-repair transaction, so that the first node starts Self-repair operation of unstructured data files; after the self-repair operation is completed, the self-repair result is generated and recorded on the blockchain. This application forms a consensus record through transactions to complete the self-repair record storage of unstructured data, and realizes self-verification of unstructured data and synchronous repair of error data to other normal nodes of unstructured data through blockchain cryptography technology. Improved data consistency and reliability.

Description

Technical field [0001] This application covers the field of blockchain technology, in particular a blockchain-based method of self-healing of unstructured data. Background [0002] The data in the computer information system is divided into structured data and unstructured data, structured data is simply a database, and non-structured data is an irregular or incomplete data structure, there is no predefined data model, and it is not convenient to use the two-dimensional logical table of the database to represent the data. For example, common unstructured data includes pictures, videos, documents, and so on. [0003] In the existing distributed storage scheme, for the storage of unstructured data, it is generally a hashed hash value on the chain, and an unstructured data is saved under the chain. If unstructured data is changed or lost due to disk reasons or other human factors, the data is completely lost. If the unstructured data has a master-slave backup mechanism, it may be co...
