In this we propose IChain, which is an open source, decentralized AI operating system based on blockchain technology. By combining blockchain technology, AI technology, cryptography, chips and trusted execution environment (TEE), IChain enables users to obtain machine intelligence capabilities provided by IChain without needing to build their own algorithms and models independently. Through the IChain platform, any users can securely share data, core algorithms, AI models, etc., without worrying about the privacy of the source data. Developers and companies can directly use the AI capabilities provided by the IChain platform. Data builders and providers can obtain the platform’s token incentives by providing data or conducting distributed data annotation. Scholars and researchers can obtain distributed computing power and labeled data required for training models through the IChain platform. People can add other AI services and models that others need to IChain, and obtain corresponding rewards from the network. Then we show how IChain can be used in the field of Energy and Power Electronic Data Storage and Forensics.
