A Review on Trust and Reputation Management Systems in e-commerce and P2P Network

The start of e-commerce introduced centralized trust and reputation management system to deal with the trust issues in the transactions since the initial transactions usually took place between businesses and consumers (B2C). However, with the development of P2P e-commerce paradigm and problems of centralized systems, such as privacy concerns and abnormal recommendations, coming to surface, the need for distributed trust and reputation management systems has become urgent, and therefore many related approaches have been put forward in the literature. However, even though the approaches are learning from the past experience and therefore improving, drawbacks like weak to attacks still exist. In this paper, Distributed Ledger Technology (DLT) and its implementation Blockchain (BC) are considered as a rather positive solution that may handle the hard problems. To ensure the effectiveness of Blockchain, its potential future trends are discussed in this article as well.
