Trusted Reviews: Applying Blockchain Technology to Achieve Trusted Reviewing System

In today’s flourishing e-business environment, reviews play a significant role in our daily products’ and services’ choices. Reviews can be described as trusted if their source was known, authentic, and reliable. Trusted Reviews aims to improve the authenticity and quality of customer’s reviews submitted to the system. In order to achieve this, Blockchain technology is implemented for its unique characteristics, such as the immutability of data to prevent fake reviews. In order to encourage members to write legitimate reviews, Thiqah -Trust Credit- will be used as an incentive, serving a significant role in our reward system. Consequently, more genuine reviews will be submitted, improving the system’s reputation legitimacy and enhancing the member’s experience. The model has been tested using Ethereum for decentralized applications. It all starts with writing a smart contract, and this contract contains the rules and conditions that will identify a review as trusted. For example, reaching a certain number of likes. Upon satisfying the contract conditions, a block will be created containing all details of the review, added to the blockchain and the writer of the review gets awarded a Thiqah credit point. The implemented solution will help business owners gain a good reputation and increase customer trust.
