Data asset transaction method, computer equipment and readable storage medium

Abstract

The invention discloses a block chain-based data asset transaction method, computer equipment and a readable storage medium. According to the method, the block chain network is established based on the Fabric block chain framework, and the data assets are used as private data to be chained, so that the specific data can be cleared within limited time while the chained data store the Hash abstract, the problem of data redundancy caused after the data assets are sold for multiple times is solved, and the storage pressure of the block chain is reduced. According to the method and the system, in combination with a DataX tool, localized storage of data assets from a chain database to a big data application database is realized, and the problem that a state database in a conventional block chain data transaction platform is not suitable for big data calculation is solved. According to the method, data streams of links such as data asset uplink, synchronization and storage are recorded, so that a data asset transaction process is perfected, and the problem of data asset transaction disputes is avoided to a certain extent.

Description

technical field [0001] The invention belongs to the technical field of blockchain and data asset transactions, and in particular relates to a blockchain-based data asset transaction method, computer equipment and readable storage medium. Background technique [0002] Due to its features of decentralization, security, reliability, non-tampering, and traceability, blockchain is gradually being used in data asset transactions, providing a credible communication environment for peer-to-peer transactions of data assets. [0003] Blockchain-based data asset transactions have gradually become the main way for data transactions between major data institutions. When blockchain technology is used for data asset transactions, it is mainly used to realize the transmission and synchronization of data assets. [0004] Due to the security, trustworthiness and traceability of the blockchain, the big data transaction records have the characteristics of trustworthiness and traceability. [0...

AI Technical Summary

Problems solved by technology

[0008] Therefore, it is difficult for blockchain-based data asset trading platforms to meet the different needs of databases in big data applications

[0009] 3. Data asset transaction transmission lacks a perfect process

[0010] At present, the data transmission of the blockchain data trading platform is mostly through the transmission of certificates on the chain, that is, the seller puts the data on the chain, and the buyer obtains the data from the chain for use. Since the blockchain is a distributed system, the nodes of both parties to the transaction are stable. Hidden dangers, there is a problem of node downtime, and operations such as data asset uploading, synchronization, and warehousing are difficult to achieve on-chain operations, and related operations are difficult to verify on-chain, which is likely to cause data asset transaction disputes
