The concept of the Internet of Things has been proposed for nearly 30 years, but it has not ushered in a real explosion so far. In this regard, some people in the industry believe that the combination of the Internet of Things system and the decentralized blockchain may alleviate the constraints of the development of the Internet of Things from the "production relationship" and achieve breakthrough development. The introduction of the blockchain may solve the problems of high connection costs of the Internet of Things, difficulties in realizing trust, poor privacy and security of user data, and low data value utilization caused by information islands.

Recently, I came into contact with Singapore-based "Cyber-Physical Chain (CPChain)", it is making a decentralized distributed IoT system public chain that combines blockchain technology and IoT technology, trying to innovate from the underlying architecture and consensus mechanism to reduce the cost of IoT system connection.

The parallel distributed architecture of "CPChain" includes a distributed cloud storage layer and a blockchain layer, which are distributed in parallel and undertake data storage and computing functions respectively.At the cloud storage layer, user data is encrypted and uploaded to the cloud; at the blockchain layer, user data is encrypted on the client side and divided into blocks, each part enters a different storage node, and the hash certificate is uploaded to all nodes of the blockchain network To ensure that the data is complete and accurate.

This parallel distributed architecture strips the data layer from the blockchain, reduces the storage burden of the blockchain, and improves scalability; and increases the number of packaged transactions in a single blockchain while the block size remains unchanged. , Improve the transaction processing speed of the public chain.

In terms of consensus mechanism, "CPChain" adopts a hybrid consensus protocol (two-layer consensus protocol) suitable for large-scale public chains. The core technology includes a distributed node reputation model and a dynamic committee selection model based on random encryption functions.

"CPChain" founder Dr. Long Chengnian said,The early stage of the project will mainly focus on the two fields of intelligent transportation, health and medical treatment, to carry out the application of the fusion technology of the Internet of Things and blockchain. Through blockchain technology, establish trust among parties involved in the transaction, provide artificial intelligence decision-making based on IoT big data, and form cross-industry chain data asset interaction and application.

"CPChain" Development Roadmap

Recently, the parallel distributed storage and computing architecture of "CPChain" has been released. Regarding the detailed progress of the development code, Dr. Long Chengnian said that "CPChain" will release the code update at the end of June, and then release the code regularly on a quarterly basis.

At present, there are about 20 team members. The founder, Dr. Long Chengnian, has decades of research and development experience in the fields of Internet of Things, distributed intelligent systems, and cyber-physical system security. He has presided over and completed a number of national, provincial and ministerial scientific research projects; Co-founder Dr. Zhao Bin has more than 12 years of experience in communication and Internet of Things research and development and R&D team management experience; co-founder Shi Qingwei is an early participant in blockchain and digital currency, and the founder of Shared Finance. There are 13 core R&D members of the project, who have experience in technology development of large companies such as Intel, Huawei, and Nokia.
