Embodiment Construction

[0024] The present invention will be described in detail below, and the specific implementation described here is only for explaining the present invention, but not as a limitation of the present invention.

[0025] The present invention provides the development of a credit investigation system for college students based on blockchain smart contracts. The specific implementation process is as follows:

[0026] First of all, the underlying chain code and network are developed using hyperledger fabric 1.1. Peer nodes are used to propose transactions, orderer nodes are used to receive transactions and verify them, kafka and zoopeeper clusters are used for specific sorting consensus, and cli interfaces are used to provide an interface for development The author writes commands to build the topology of the consortium chain.

[0027] After the contract is installed, the contract is packaged through the JAVA SDK, the web backend and the web frontend are written, and the application l...

Abstract

The invention discloses a college student digital personal credit investigation method based on a blockchain intelligent contract. The method comprises the following steps: a student node uploads a personal credit information original file to a storage layer, then deploys an intelligent contract containing personal credit basic information into a block chain network, and broadcasts the personal credit information original file through a consensus whole network, and each user node accesses the personal credit information original file by calling each module function of the intelligent contract.Based on the blockchain intelligent contract technology. The method is based on the blockchain intelligent contract technology, and has the characteristics of decentralization, public transparency, no tampering, convenience in tracing and reliability in database; and any user connected to the blockchain network and provided with the blockchain digital wallet can deploy the own intelligent contract, so that the credit investigation information of the user can be managed. According to the method, the problems of serious information centralization and serious counterfeiting of the existing digital personal credit investigation system are solved.

Description

technical field [0001] The invention relates to the field of blockchain smart contracts, in particular to a digital personal credit investigation method for college students based on blockchain smart contracts. Background technique [0002] At present, in China, the existing personal credit information application system is based on centralized nodes. There are mainly three social credit information systems in the field of credit information, namely government-led, market-led, and membership-based. my country's credit investigation system is government-led, with the central bank as the center of public credit investigation, and market-oriented credit investigation as an important supplement. my country's social credit reporting agencies, credit rating agencies, local credit information service agencies, and emerging private credit reporting service agencies are all under the supervision of the People's Bank of China, such as Shanghai Credit, Huaxia Credit, Sesame Credit, and...
