ScienceSoft helped an agricultural product wholesaler design a blockchain-based marketplace. As a rule, blockchain development companies programming smart contracts can execute an independent audit, like we do at ScienceSoft. Security is a critical aspect to think of when creating smart contracts as the code of smart contracts can’t be modified after deployment to patch security vulnerabilities. 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
