Rewarding Reviews with Tokens Using Smart Contracts

Research shows that 68% of online purchases are influenced by the reviews of the products that are being sold. Online retailers know the importance of online reviews and how those reviews impact their business. Online review sites are widely used in the hotel sector and by online retailers. Because these evaluations account for such many sales, there is always the risk that they may be exploited or interfered with. The issue is that these systems are highly centralized, leaving them vulnerable to manipulation and control. In this paper, we discussed the possibility of a decentralized, unbiased review system and an abstract implementation of that system. This review system will be a collection of smart contracts which can be deployed on the Ethereum blockchain. The blockchain's decentralized characteristic might be used to establish an unbiased and fair review system that increases consumer connections and confidence. On Test Networks, we build and test smart contracts in this project. The architectural flow and system components are also provided. In conventional review systems, the user usually adds a new review, and this review is stored in a centralized database of the service provider. The service provider can edit the review, it can also be permanently deleted from the platform. Since reviews drive a major part of the sales, this control over the reviews system can affect users who might have found the deleted review to be useful. A blockchain is a continuously increasing collection of linked and encrypted documents known as blocks. When a blockchain is used, a digital item's ability to duplicate indefinitely is eliminated. Consumer review systems might benefit from blockchain's decentralized and tamper resistant features.
