CPChain is a new distributed infrastructure for next generation Internet of Things (IoT). CPChain intends to build a fundamental data platform for IoT system 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 current “chimney architecture” of IoT systems, reducing connectivity cost of devices, protecting data privacy and maximizing the value of IoT data.
The key to Space Chain is to deploy all blockchain nodes on satellites so as to bring blockchain technology into space, adding a new dimension to blockchain’s core concept of distributed ledger by making use of space technology and advantages of space resources. As a space blockchain platform featuring data collecting, computing, application and storage, Space Chain uses satellites as its blockchain nodes for realizing direct on-satellite data processing and secure in-space data storage through cryptographic technologies such as quantum communications. Different from ground-network-based blockchain technology, Space chain provides a broader coverage and is based on a network of LEO satellites for achieving broad-based connectivity so that anyone and anything could become the user of blockchain technology anywhere and anytime.
