医疗众筹作为一种新的互联网筹款募捐活动,已被广泛关注和应用,但传统医疗众筹组织存在资金挪用、资金动向不明、用户隐私信息泄露等问题。引入区块链技术,基于智能合约机制与属性、系统结构和业务逻辑,搭建基于区块链技术的医疗众筹系统,将区块链技术与非对称加密相结合,满足了用户隐私不被泄露、资金去向明朗等需求。将医疗众筹平台与传统医疗众筹平台进行比较分析,证明该方案能够有效解决资金挪用、筹款退回难和用户隐私泄露问题。

As a new Internet fundraising and fundraising activity,medical crowdfunding has been widely concerned and applied,the current medical crowdfunding organizations have problems such as misappropriation of funds,unclear fund movements,and leakage of user privacy information.In order to solve the above problems,this paper proposes a medical crowdfunding scheme based on Ethereum smart contracts.Based on the smart contract mechanism and properties,the system structure and business logic are introduced in detail,and the specific system implementation of the platform is given.This paper builds a medical crowdfunding platform based on blockchain technology,which combines blockchain technology with asymmetric encryption to meet the needs of users'privacy not being leaked and the whereabouts of funds being clear.By comparing and analyzing the medical crowdfunding platform and the traditional medical crowdfunding platform,it is proved that the scheme can effectively solve the problems of fund misappropriation,difficulty in returning fundraising and leakage of user privacy.
