Problems solved by technology

[0008] Traditional databases are generally private, but blockchain data is open and verifiable, ensuring completeness and transparency. Users can confirm that the blockchain data they retrieve and consult is complete and has not been tampered with, while traditional databases are very Difficult to guarantee

[0054] The transaction records from the sender are absolutely tamper-proof. SDEC hopes to load the log of the demander into the blockchain. Since the demander is the payer, it is reasonable for SDEC to charge according to the actual data received. Therefore, in the In one step, the demander's log can be directly loaded into the blockchain, and the performance of writing to the blockchain can be tested. If the performance can meet the needs of the actual business environment, SDEC will improve from the laboratory environment to the commercial environment, and realize path utilization;

Abstract

The invention belongs to the field of cloud computing resource management, and relates to a distributed data storage, point-to-point transmission and consensus mechanism technology, in particular to adistributed data transaction accounting system based on a block chain. A front-end processor container is used as a communication tool to send and receive transactions among all physical machines; analliance chain is built by using an open source Hyperledger Fabric; a Monitor is writtenby using java to write the transaction information into a block chain; rich query is carried outby using a couch db database; and the block generation information is visually displayed by using an open source tool fabric-explorer. According to the invention, the problems of over-centralization, lack of trust,possible modification of data in a transmission process and the like of traditional data storage are solved, and consistent, tamper-proof, automatic and efficient bill recording, account book storageand intelligent clearing are realized.

Description

technical field [0001] The invention belongs to the field of cloud computing resource management, relates to distributed data storage, point-to-point transmission, and consensus mechanism technologies, and specifically relates to a blockchain-based distributed data transaction accounting system. Background technique [0002] According to data, blockchain technology is considered another disruptive core technology after electricity and the Internet. As an underlying technology for building the Internet of Value, the blockchain will change the way of value transmission. The emergence of the blockchain will solve a very important problem-how to obtain unknown trust. [0003] Blockchain technology is based on a decentralized peer-to-peer network, using open source software to combine cryptography principles, time series data and consensus mechanisms to ensure the coherence and continuity of each node in the distributed database, so that information can be instantly verified and ...
