Architecture of a Blockchain-Based Decentralized Marketplace
Review submission is controlled by smart contracts to authorize reviews from buyers of a particular product only. Marketplace smart contracts serve as the back-end business logic of the marketplace – they define how the user behavior unfolds depending on the input data. Smart contracts can verify the legitimacy of users leaving product feedback, authenticate their reviews, and lock reviews in the blockchain for immutability to prevent changes upon submission. Blockchain instantly encrypts transactional data and stores it in an immutable, tamper-resistant ledger, protecting sensitive buyer information from breaches and theft. For now, IBM is one of the best examples of the companies that make global trade possible through smart contracts development. Another point is that the large portion of the user’s data is confidential, thus some sorts of promotion are impossible to use — like product recommendations, bundling and personalization algorithms as well as target future promotions.
