Description

Technical Field

[0001] The present invention relates to the field of blockchain technology, and in particular to a method and system for building full life cycle product safety supervision based on blockchain. Background Art

[0002] Product safety issues are common in our daily life. Once a product safety issue occurs, it will not only cause varying degrees of losses to the people, but also require law enforcement agencies to complete a large amount of flow investigation when conducting investigations. Existing product packaging barcodes or store receipts are only used to achieve in-and-out storage or other information records, and this part of the resources has not been fully utilized.

[0003] Based on the above problems, the present invention proposes a method and system for building full life cycle product safety supervision based on blockchain. Summary of the invention

[0024] The blockchain layer selects mature blockchain platforms such as Hyperledger Fabric or Ethereum, and customizes and optimizes them according to actual needs; the blockchain layer provides an API interface for upper-layer applications to read and write data;

[0025] The smart contract layer is responsible for defining and automatically triggering the business logic and rules for product safety regulation, including triggering alerts, recording violations, and enforcing fines;

[0026] The smart contract layer uses the smart contract programming language Solidity to write smart contract code and deploy it to the blockchain layer; smart contracts will be automatically executed according to preset conditions and rules without human intervention.

[0027] The application layer is responsible for providing specific business applications for all parties involved (such as manufacturers, regulators, consumers, etc.), and calling the API interfaces provided by the blockchain layer and the smart contract layer to realize the reading and writing of data and the execution of smart contracts, display the data of the entire life cycle of each product, and provide data query, report submission and complaint handling functions;

[0028] The application layer uses Web development technologies (such as HTML, CSS, JavaScript, etc.) to build the front-end interface and uses back-end development technologies (such as Java, Python, etc.) to process business logic and data interaction;
