Abstract: Current online review systems face challenges due to fraudulent activities, such as paid manipulation of reviews and automatic filtering without user awareness, which reduces transparency and credibility. Blockchain technology offers high transparency, as all actions can be publicly traced; however, trade-offs such as cost and response time must be considered. This study investigates the feasibility of applying blockchain technology to online review systems by evaluating four implementation approaches using Ethereum smart contracts. The results show that using IPFS for data storage is an effective way to reduce transaction costs, and minimizing reliance on smart contract states further decreases costs. Although response time in blockchain and IPFS systems is slower than in centralized systems, review posting does not require real-time performance, making this trade-off acceptable. From a business perspective, introducing posting costs can reduce fake reviews, and additional features such as reward systems, bogus review voting, and a global database enhance system credibility. Therefore, blockchain-based online review systems present a promising approach to improving trustworthiness and transparency.
