The 5AI Smart IoT Public Chain is dedicated to building the next generation of smart IoT public chains. This is an entirely new smart IoT platform based on the DPoR (Delegated Proof of Randomness) consensus algorithm, integrating peer-to-peer AI with blockchain-based computing. It envisions connectivity with trusted IoT devices in the real world and future machine sensors, enabling effective analysis and utilization of vast amounts of data and resources on the blockchain. Additionally, the 5AI-IoT platform, built on IoT-friendly design principles, forms a complete ecosystem comprising three main sectors: IoT smart economy, IoT instant messaging, and IoT service ecosystem. Firstly, by combining digital assets and smart virtual identity technologies, we create a new digital economy - an AI-based IoT smart economy system. The 5AI, designed to complete the peer-to-peer network business cycle, will establish an instant communication platform based on 5G signal services. Users worldwide can engage in social interactions, business collaborations, value exchanges, and more within the ecosystem using tokens, all while ensuring the security and privacy of user information.
