基于区块链的可监管慈善系统设计与实现

Design and Implementation of Blockchain-Based Regulated Charity System

近年来,中国慈善事业的快速发展带来了许多问题,现有的慈善管理系统是中心化的、慈善募捐过程不透明的,这导致了难以获得捐赠者的信任和捐赠。区块链的可信计算模型为解决上述问题提供了新思路。本文采用联盟链Hyperledger Fabric作为区块链平台实现了可监管慈善系统,制定了慈善项目发起、捐款、执行的智能合约,并设计了Charity Coin作为系统数字货币,保证捐款流向可追溯。最后,性能测试表明,该系统能够满足应用要求。

In recent years, the rapid development of philanthropy in China has brought many problems. The existing charity management system is centralized and the process of charitable fundraising is not transparent, which makes it difficult to gain the trust and donation of donors. The trusted computing model of blockchain provides new ideas for solving the above problems. This paper uses the consortium blockchain Hyperledger Fabric as the blockchain platform to implement a regulated charity system, formulates smart contracts for charitable project initiation, donation, and execution, and designs Charity Coin as the system digital currency to ensure that the flow of donations can be traced. Finally, performance tests show that the system can meet the application requirements.
