Military application of blockchain Technology

3. Blockchain is the core supporting technology of digital cryptocurrency system represented by bitcoin. The core advantage of blockchain technology is decentralization. It can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the common high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

4. A: blockchain technology has been applied in many fields
I. financial field
blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields< Second, the Internet of things and logistics
blockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management. This field is considered as a promising application direction of blockchain
Third, public service
blockchain is closely related to people's proction and life in public management, energy, transportation and other fields, but the centralization of these fields also brings some problems, which can be transformed by blockchain
IV. in the field of digital right
through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works and ensure the authenticity and uniqueness of ownership< 5. In the field of insurance
in terms of insurance claims, insurance institutions are responsible for fund collection, investment and claims settlement, and often have higher management and operation costs< 6. In the field of public welfare, the data stored on the blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios.

5. Red police home, there is a modifier

6. There are many potential applications of blockchain technology in the military field:
intelligence work performance incentive. Blockchain has anonymity when recording transactions, and can be used for covert directional payment of incentive fund for intelligence work. As we all know, intelligence providers or "informants" need to keep their identity and whereabouts secret. Traditional payment methods such as transfer and cash are easy to be tracked or even locked. But through bitcoin as a payment intermediary, we can skillfully "break" the payment channel, making it difficult to trace the flow of intelligence funds, so as to effectively protect security. Bitcoin trading platform plays the role of "black box" in the whole payment process, in which the three key links of "purchase transaction exchange" can be completed anonymously, realizing the key information hiding of both parties
life cycle management of weapons and equipment. It is necessary to register and manage the important information in the whole life cycle of equipment from project demonstration, proction verification, delivery to service and retirement. The current recording method is usually paper or electronic media. This traditional method has some defects, such as difficult to guarantee safety, difficult to transfer and transfer, lack of effective supervision and so on. If the introction of blockchain technology allows the superior competent departments, equipment management departments, equipment users, and even equipment manufacturers to participate in the update and maintenance of equipment combat and technical status, forming a distributed and supervised file registration network, and all parties keep a complete file , the above problems can be effectively solved, and the security and reliability of files can be improved Convenience and credibility
military intelligent logistics. In order to realize the intelligence of modern military logistics, the intelligence of logistics department, warehouse, material and material demander is indispensable, which constitutes the small Internet of things. Blockchain technology can effectively solve the problems of network communication, data storage and system maintenance. The dynamic and autonomous networking of people and things in the system forms a decentralized peer-to-peer network without a central server. The distributed structure improves the viability of the system; The nodes accessing to the network can communicate with each other directly or by relay mode to realize the free interaction of information; The important data information in the logistics chain, such as user demand, storage goods, loading and transportation, distribution and transfer, are stored in each block; The maintenance of blockchain must be supervised by the nodes of the whole network. The illegal operation of indivial nodes will be rejected and resisted by most nodes, which ensures the orderly and efficient operation of the system (from science and technology daily)
of course, blockchain is more used in the financial field, such as digital currency crowdfunding of coin Ying China; China Post Bank's fund trusteeship and so on.
