Abstract

The invention discloses a method and a system for realizing asset traceability based on a Fabric block chain platform, which belong to the technical field of block chains, and comprise the following steps: in an asset chaining step, obtaining an article information list of an article to be chained, generating a block for storing the article information list, and storing the block into an off-chaindatabase; generating an article label, and generating transaction information according to the article label and the public key of the producer; storing the block head information and the transactioninformation into a block chain; in the asset transaction step, after a block link receives a transaction request initiated by an owner of a to-be-transacted article, obtaining public keys of the owner and a receiver and an article label through analysis to generate transaction information, and storing the transaction information in the block chain; in the asset tracing step, inquiring an out-of-chain database and a block chain account book according to an article label so as to acquire detailed information and circulation details of a to-be-inquired article. According to the invention, the problems of narrow coverage and fast expansion of data on a chain in the existing asset traceability application can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of block chain, and more specifically relates to a method and system for realizing asset traceability based on the Fabric block chain platform. Background technique [0002] The current supply chain is a linear economic model that directly or indirectly satisfies supply demand, but this model has some shortcomings, such as the relationship between supply chain members is based on a certain center, and it is difficult for consumers to obtain information about the source of products , that is, it is difficult to realize the application of asset traceability. It is of great practical significance to study the application of asset traceability, mainly for the following reasons: (1) The traditional supply chain is a centralized design, which cannot guarantee the authenticity of the data in the supply process when the trusted central organization is attacked; ( 2) Decentralized applications are developing rapidly...
