20HR2800, IoT 디바이스를 위한 Lightweight 블록체인 표준개발,
- Blockchain is an emerging technology, its most important characteristics are traceable, un-erasable, immutable, and time-stamped. It is able to efficiently ensure integrity, authenticity, and auditability for all transactions. Blockchain has important impacts and benefits for data exchange and sharing in support of Internet of things (IoT) and smart cities and communities (SC&C). In most of the IoT and SC&C scenarios, it is necessary to ensure data processing, circulation, sharing and management for all trust operations. Blockchain technologies can meet these needs.
Recommendation ITU-T Y.4560 specifies the requirements, functional models, a platform, and deployment modes of blockchain-based data exchange and sharing for supporting IoT and SC&C.
