Abstract

The invention belongs to the technical field of block chains, and particularly relates to a material assistance traceability system based on Fabric. The system provided by the invention comprises a client, an IPFS (Internet Protocol File System), a Web service, a FabricSDK (Software Development Kit) and a Fabric network. The client provides an operation use interface for the user; the Web serviceprocesses the request received by the IPFS from the client; the Fabric network is composed of an account book, a channel, a chain code, a CA, a peer node and a sorting node. The CA can manage the authority and resources of the role in the Fabric network; wherein the chain code is used for realizing main service logic of the system and performing various interactions with an account book; internalnodes of the Fabric network are provided with interfaces based on a gRPC protocol and are used for data interaction; the Fabric also provides an SDK (Software Development Kit) of multiple language versions; various resources in the Fabric network, including account books, transactions, chain codes, events and authority management, can be accessed through the SDK. The system can publish demands andassistance, record assistance material transfer information and ensure authenticity and traceability.

Description

technical field [0001] The invention belongs to the technical field of blockchain, and in particular relates to a fabric-based material aid traceability system. Background technique [0002] At this stage, some non-profit organizations have exposed problems such as uneven distribution of materials, non-openness and transparency, and have fallen into a crisis of trust. The development of blockchain technology provides ideas for solving this problem. [0003] Blockchain technology was first applied to the Bitcoin system as a solution to the problem of database security and trustless administrators. In the Bitcoin system, the blockchain is its core component. The decentralized database of the blockchain is managed autonomously by the servers on the peer-to-peer network, which also makes Bitcoin the first digital currency to solve the double payment problem. . [0004] The Hyperleder project was launched by the Linux Foundation in 2015. It aims to use blockchain technology to ...
