This field is considered as a promising application direction of blockchain.
Public service field
Blockchain is closely related to people's production and life in public management, energy, transportation and other fields, but the centralized nature of these fields has also brought some problems, which can be transformed by blockchain. The decentralized and fully distributed DNS service provided by blockchain realizes the query and resolution of domain names through peer-to-peer data transmission services between nodes in the network, which can be used to ensure that the operating system and firmware of important infrastructure have not been tampered with, monitor the status and integrity of software, find bad tampering, and ensure that the data transmitted by systems using Internet of Things technology has not been tampered with.
Digital copyright field
Through blockchain technology, works can be authenticated to prove the existence of works such as text, video and audio, and ensure the authenticity and uniqueness of ownership.
