Integration of IoT & Blockchain. CPChain is a new distributed infrastructure for next generation IoT. CPChain intends to build a fundamental data platform for IoT systems in combination with distributed storage, encryption computation and blockchain technologies, providing the whole process solution from data acquisition, storage, sharing to application. CPChain is a promising solution to a series of challenges of the current "chimney architecture" of IoT systems, reducing connectivity cost of devices, protecting data privacy and maximizing the value of IoT data. The core feature of the CPChain is to realize the transmission of the value of cyber-physical systems. CPChain’s main technological innovation is to propose a systematic scheme to address the scalability and real-time problems of blockchain technology in IoTs from the perspective of data storage and computation, and consensus protocols, including parallel distributed architecture, two-layer hybrid consensus mechanism and lightweight side chain consensus protocol.
