Agricultural product voucher tracing system based on Ethereum block chain technology and tracing method thereof

Abstract

The invention provides an agricultural product voucher tracing system based on an Ethereum block chain technology and a tracing method thereof, and relates to the technical field of block chains. The agricultural product voucher tracing system based on the Ethereum block chain technology and the tracing method thereof comprise: an interstellar file system which is used for assisting a block chain system to store files and receiving agricultural product voucher data at the same time; the smart contract that is used for ensuring a data storage agreement; an Ethereum block chain, wherein the Ethereum block chain is used for ensuring distributed storage of data among the nodes. The interstellar file system, the smart contract and the Ethereum block chain are connected, and data transmission among the interstellar file system, the smart contract and the Ethereum block chain is realized through a network. The agricultural product voucher tracing system based on the Ethereum block chain technology and the tracing method thereof provided by the invention have the advantages of good data security and high credibility.

Description

technical field [0001] The present invention relates to the field of block chain technology, in particular to an agricultural product voucher traceability system and a traceability method based on the Ethereum block chain technology. Background technique [0002] Blockchain and artificial intelligence are the most important keywords in the fourth industrial revolution. With the rapid development and popularization of blockchain technology in recent years, it has attracted a lot of attention. The blockchain applies technologies such as cryptography, distributed storage, consensus mechanisms, and smart contracts, and establishes a new type of quantifiable trust and incentive system, which greatly improves transparency, reduces trust risks, reduces costs, and improves Efficiency will change the way and trust mechanism of the entire social value transmission, so it is considered as a disruptive core technology. The development of blockchain technology provides a trusted execut...

AI Technical Summary

Problems solved by technology

[0003] There are a lot of data stored in the database in a centralized way in the traceability of agricultural product certificates. There are many defects in the centralized data storage. There are many human factors in the centralized storage data storage, which affect the security of the central data storage and the authenticity of the data. , the data can be changed artificially, and it is vulnerable to attack and cause data paralysis or loss

Because of the lack of security and the authenticity of the data is questioned, the credit of traditional data storage may need a third-party organization to achieve
