Nowadays, Blockchain technology can address risks by providing a decentralized database that ensures data integrity and prevents unauthorized alterations. Traditional centralized database systems are the preferred choice for organizing large collections of data due to their rapid and systematic data accessibility. However, the concentration of access authority in the hands of administrators or individuals with power introduces potential risks to data integrity. This research proposes a decentralized approach to online product reviews that integrates a centralized database with Blockchain technology. By integrating these two systems, users can access and review content data with the assurance that the information remains unaltered. The research proposes a method to verify the integrity of data stored in the centralized database and a strategy to optimize the balance between trust and gas fees when storing data on the Blockchain. The proposed approach has the potential to improve the trustworthiness and security of online product reviews. It can also help to reduce the risks of data manipulation and fraud. Our method serves to enhance the credibility of the database.
