A novel application for analysing customer revies using Blockchain

Abstract

Consumers can make informed purchase decisions and learn more about things by sharing their experiences with
others through user reviews. To enhance their business, internet retailers and service providers may modify
customer evaluations by adding false positive remarks and removing negative ones. Customer reviews that have
been edited may mislead customers and alter the original content of the reviews. Modern systems lack a safe,
effective, and user-friendly consumer review system. In this work, we provide RevBloc, a highly efficient, secure,
and easy-to-use customer review system. Because RevBloc is built on blockchain technology, user evaluations
can be maintained in a distributed ledger, preventing a single or small number of unfriendly parties from
influencing the reviews. We implement a RevBloc proof-of-concept prototype and describe its performance to
illustrate the strategy's practicality.
