SUPTChain is based on Cloud Operation System public blockchain technology and developed three side chains which focus on smart driving, intelligent transportation, and insurance technology. The purpose of SUPTChain is to build a complete trip ecosystem which is based on trustworthy cloud-computing COS public chain, AI intelligent driving, and IoT-based (Internet of Things-based) three vertical applications. COS public chain is on account of MTP technology and Itsuku PoW (Proof of Work) which is constructed by Merkle Tree. Our blockchain combines PDP technology and form up a trustworthy cloud-computing system.
