Dear ITC community: We are pleased to announce that the main net IoT Chain code has passed the audit and it’s open source. In this audit, the security agency DigApis Technology conducted a comprehensive analysis of the code for cryptographic algorithms, smart contract virtual machines, account and transaction model security. The report shows that the main net code of the ITC has passed the security audit successfully, which further reflects the security and standardization of the IoT chain as a public blockchain. ITC is a secure IoT light operating system driven by blockchain technology. It is dedicated to building a decentralized pan-ecological public-chain infrastructure network to provide a secure and scalable public chain for the Internet of Things.
