RPC-Chain:crowdsourcing model chain based on reputation mechanism and controlled PRE
This paper addressed the challenges of trust issues,asymmetric contribution and benefit relationships,and data se-curity sharing in crowdsourcing by proposing an RPC-Chain,a crowdsourcing model chain based on a reputation model and proxy re-encryption(PRE).RPC-Chain abstracted the transaction process of the crowdsourcing model based on Hyperledger Fabric.Firstly,it improved the reputation mechanism to enhance the overall efficiency and fairness of the system.Secondly,it introduced proxy re-encryption to ensure secure data sharing services.Finally,it built a crowdsourcing blockchain simulation platform using Fabric,and conducted related tests.The experiments demonstrate that the proposed scheme shows certain ad-vantages in model design,secure data encryption sharing,and the incentive effect of the reputation model.
