Blockchain-Based Reputation Systems: Implementation Challenges and Mitigation

Reputation expresses the beliefs or opinions about someone something that are held by an individual a community. Management Systems (RMSs) handle representation, computation, and storage of reputation in some quantitative form, suitable for grounding trust relations among parties. Quantifying is important situations, like online service provision, which involve interaction between parties who do not know (and potentially distrust) each other. The basic idea to let rate When party considered interaction, its ratings can be aggregated order derive score deciding whether it not. While much valuable research work has been done on reputation-based schemes, problem establishing collective management system itself never fully solved. Recently, several researchers have put forward using Distributed Ledger Technology (DLT) as foundation implementing trustworthy RMSs. purpose this paper identify critical problems arise when DLTs used manage evidence previous compute reputations. proposes practical solutions describes methods deploy them top standard DLT Ethereum family.
