摘　　要：为解决众包面临的信任问题、不对称贡献与收益关系以及数据安全性共享等挑战,提出一种基于信誉模型与受控代理重加密(PRE)的众包模型链,即RPC-Chain。RPC-Chain基于超级账本Fabric,将众包模型的交易流程抽象化。首先,完善信誉机制提高系统整体的效率与公平;其次,引入受控代理重加密以确保数据安全共享服务;最后,使用Fabric搭建众包区块链仿真平台并进行了相关测试。实验表明,该方案在模型设计、数据安全加密共享和信誉模型的激励效果等方面显示出一定优势。This paper addressed the challenges of trust issues, asymmetric contribution and benefit relationships, and datasecurity sharing in crowdsourcing by proposing an RPC-Chain, a crowdsourcing model chain based on a reputationmodel and proxy re-encryption (PRE). RPC-Chain abstracted the transaction process of the crowdsourcing modelbased on Hyperledger Fabric. Firstly, it improved the reputation mechanism to enhance the overall efficiency andfairness of the system. Secondly, it introduced proxy re-encryption to ensure secure data sharing services. Finally, itbuilt a crowdsourcing blockchain simulation platform using Fabric, and conducted related tests. The experimentsdemonstrate that the proposed scheme shows certain advantages in model design, secure data encryption sharing,and the incentive effect of the reputation model.
