Blockchain medical electronic bill platform

1. 1. What is blockchain? In a word
A: blockchain is an encrypted database chain, that is, the transaction data in multiple timestamps / events are encrypted and linked together, and the data can not be tampered with or shared
2. Performance and logic:
A. external operation forms: bank deposit and withdrawal, remittance, account in and out, shopping, currency issuance, capital transaction, etc
B. internal logic processing (software program): after human operation, the data will be encrypted first and then stored in the database. After the program, the data will be divided into regions, such as the data in the event and time stamp will be classified and put together into a region. Multiple events and data in timestamps are associated to form a blockchain. The encrypted data can be shared, but not tampered with
C. forms of sharing: querying personal information, auditing, etc. Query permission / sharing permission: different permissions can query different data. For example, the bank can query the information of all people, and the indivial can only query the indivial
3. Most of the examples are different, but the logic processing ideas are the same, but the implementation methods and operations are different
4. Blockchain: it has the characteristics of encrypted data, tamperable data and shared data
5. Blockchain Technology: the technology of encrypting, partitioning and sharing data with editing programs
there are suggestions for guidance
application fields: finance, it, commodity sales, online shopping, etc.

2. At present, it is 5173 and Taobao. Taobao is cheap. 5173 is about 20 percent

3. At present, it is in the early stage, and the application of blockchain technology is still vigorously supported by policies. The SMIC blockchain service platform launched by Changsha high tech Zone also solicits enterprises to go on the chain, which is a blockchain + public service mode.

4. If you are a sophomore in high school, you can calculate the problem of analytic geometry
there's no saying that kind of trouble
if you can count all of them, you are definitely well trained in computing.

5. The combination of blockchain and bill can be developed into digital bill. The so-called digital bill is not a new physical bill, nor a pure virtual information flow. It is a brand-new bill presentation form developed by using blockchain technology, combining with the existing bill attributes, regulations and market. Compared with the existing electronic bill, it is completely different in technical architecture. For the specific content of the scheme, I think we can take a look at Yingtang Zhongchuang, which is good at blockchain application development.

6. This is part of the application of blockchain in the financial instry, and the feasibility of the integration of blockchain and bills is great
bill is a kind of valuable voucher, which needs a hidden "third party" role to ensure the safety and reliability of both parties in the transaction. However, with the help of blockchain, there is no need for a third party to supervise and verify the information transmitted by the two parties, nor for a specific physical object to be used as a proof to connect the two parties to obtain trust, thus realizing the "invisible" transmission of value between point-to-point
in the development of bill platform based on blockchain, Yingtang Zhongchuang said that the application of blockchain technology in the development of bill platform has the following functions: to realize the disintermediation of bill value transmission; Effectively prevent the risk of bill market; Change the existing system structure of electronic commercial draft; Improve operation efficiency; Standardize the market order and rece the cost of supervision
the advantages of the blockchain bill platform are as follows: the system construction and data storage do not need a central server, nor do they need a central level application; The integrity, transparency and verifiability of data can be traced and queried for any value exchange; The form of smart contract makes the bill programmable and controllable in the whole life cycle.

7. Ordinary electronic bills are stored in different platform media, which can not be well managed, and there is a problem of authenticity verification, so it is impossible to obtain the authenticity from the ticket. Ant chain electronic bills can be connected to a large number of billing units, including hospitals, schools, traffic police, etc., in one chain. They can be stamped in the whole process of generation, transmission, storage and use. The whole process can be traced and tampered with, and the authenticity and uniqueness are guaranteed. Thank you for accepting my answer

8. Since last year, ant chain and Zhejiang Province have built the country's first blockchain e-bill platform, which allows people to make an online appointment directly without having to queue up repeatedly to pay at the required window. To be more accurate, it is to use unified digital encryption technology on the electronic bills for charging, so that each bill has a unique two-dimensional code "ID card", which can check the authenticity in a few seconds, fundamentally saving the cost, and more importantly, increasing the accuracy. After all, it is difficult and easy to make mistakes in manual operation, Now with the e-bill platform, both hospitals and indivials are the biggest beneficiaries.
