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.

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.

The best practice is testing both internal and external behavior of smart contracts. As smart contracts can’t interact with outside systems, there will an intermediary – a third-party service named blockchain oracl
