Can Tongji Hospital go to medical insurance center to report
Beidou pass needs to have three elements: rights and interests, encryption and circulation. Digital proof of rights and interests: a token must be a certificate of rights and interests in digital form, which represents a right, an inherent and intrinsic value. Encryption: the authenticity, tamper proof, privacy protection and other capabilities of the pass are guaranteed by cryptography. Negotiable: the pass must be able to flow in a network so that it can be verified anytime, anywhere. Tongzheng and blockchain are two different things, but they are the best partners. As we all know, Tongzheng is the most characteristic application of blockchain. A blockchain without Tongzheng is not much better than a distributed database
blockchain is the back-end technology of the new world, while Tongzheng is the front-end economic form of the new world. The two things are completely independent. However, when Tongzheng is combined with blockchain, it can proce the ability to break through the boundary and promote the reconstruction of proction relations. What it brings is not the optimization of efficiency, but the improvement of mode, It is the transformation of proction role and the subversion of proction relations in structure< br />
what is token economy? At present, most people focus their attention on the legend of soaring prices and all kinds of sudden wealth. It is a pity that the true face of the circular has been covered up. You know, there is a new concept called "token economy", which translates into "token economy", and literally means the economy that makes full use of token economy. Tongzheng inspires and encourages people to take out all kinds of proof of rights and interests, such as tickets, points, contracts, certificates, qualifications, etc., and put them on the blockchain for circulation, so that the market can automatically find their prices. At the same time, these are things that can be verified and consumed in real economic life
this is what we mentioned above: the economy of pass is the economy that makes full use of pass. General Certificate economy is a general certificate economy. In this economy, some important values and rights and interests are certificated. With the help of blockchain or trusted centralized system, this system can be operated and digital management can be brought into full play. If Tongzheng economy develops for another 30 years, we will feel that in the pre Tongzheng era, it is very primitive and backward to rely on modern digital management based on accounting principles and equity methods. Tongzheng economy will push human digital management ability to a new height. It's not only the middlemen, but also the joint-stock companies, which have appeared for 500 years as a model of human business cooperation, as well as the whole organizational structure and the relationship of interest distribution, that have been subverted by Tongzheng economy.
Beidou-3 satellite navigation system provides two service modes, namely open service and authorized service
the open service is to provide free positioning, speed measurement and time service in the service area. The positioning accuracy is 10m, the time service accuracy is 50ns, and the speed measurement accuracy is 0.2m/s. Authorization service is to provide more secure positioning, speed measurement, timing and communication services as well as system integrity information to authorized users
Construction Objective:
the construction objective of beidou-3 satellite navigation system is to provide land, sea and air navigation and positioning services for Chinese military and civil users in China and its surrounding areas, promote the application of satellite positioning, navigation and time service functions, provide positioning and orbit determination means for aerospace users, meet the needs of weapon guidance and navigation and positioning information exchange
extended data
functional features:
the Beidou system has the following characteristics: first, the space segment of the Beidou system uses a hybrid constellation composed of three kinds of orbit satellites, which has more high orbit satellites and strong anti occlusion ability than other satellite navigation systems, especially in low latitude areas. Second, the Beidou system provides navigation signals of multiple frequency points, which can improve the service accuracy through the combination of multiple frequency signals. Third, the Beidou system integrates navigation and communication capabilities, and has five functions: real-time navigation, fast positioning, accurate time service, position report and short message communication service
engineering significance:
after Beidou provides global services, all walks of life have increased their confidence in the application of Beidou and made a comprehensive layout of Beidou instry. For example, business integration with traditional application fields such as transportation, agriculture, forestry, animal husbandry and fishery, electric power and energy is deepening. At the same time, with the arrival of 5g business era, Beidou is accelerating the integration with new technologies such as new generation communication, blockchain and artificial intelligence. The new signal has also given birth to new procts. The integrated navigation and positioning chip with 22 nm RF baseband technology, which supports the new signal of beidou-3, is smaller in size, lower in power consumption and higher in accuracy, and has realized large-scale application
