摘要
传统筹款捐助平台的集中式管理难以满足高可信机制的需求,筹款信息真假难辨,善款流向不透明。区块链技术的去中心化、数据不可篡改、可溯源、点对点交易等特点为构建可信捐助平台奠定了基础。由此以区块链技术为基础,提出了一种基于以太坊智能合约的捐助方案。首先,将筹款信息和捐款交易事件等存储在以太坊区块链上,并利用保证金机制保证了数据的真实性和可溯性;同时,阐述了该方案的架构模型,提出智能合约算法Donate代替人工操作,防止善款挪用和久未到账问题;最后,通过基于智能合约的可信筹款捐助平台验证了该方案的可行性。将所提平台与传统筹款平台比较分析,证明了该平台能安全有效地防止虚假筹款和善款挪用。
The centralized management of traditional donation platforms is difficult to meet the needs of highly trusted mechanism.The truth of fund-raising information is difficult to distinguish,and the flow of funds is not transparent.Blockchain technology has characteristics of decentralization,data not being tampered,traceability,and peer-to-peer transaction,which lays a foundation for building a trusted donation platform.Therefore,based on the blockchain technology,a donation scheme based on the Ethereum smart contract was proposed.Firstly,the fund-raising information and donation transaction events were stored on the Ethereum blockchain,and the margin mechanism was used to ensure the authenticity and traceability of the data.Meanwhile,the architecture model of the scheme was described.The smart contract algorithm Donate was proposed to replace the manual operations in order to prevent the misappropriation and long-term nonpayment problems of funds.Finally,the feasibility of the scheme was validated by the trusted fund-raising and donation platform based on smart contract.Compared with the traditional fund-raising platform,it is proved that the proposed platform can prevent false fund-raising and fund misappropriation safely and effectively.
