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.
ITC is designed to solve the severe safety problems of present IoT. ITC applies a combination of asymmetric encryption of cryptography, semi-homomorphic-encryption ciphertext computing technology and distributed architecture without data center. Therefore, ITC can not only protect the users' devices from being attacked by hackers, ensuring its controlling right safety; but also defend users and their devices' data safety sovereignty and privacy security. For example, the data of intelligent device, such as the camera, can only be checked by users themselves.
