Combination of blockchain and intelligent bill

1. The definition of Chongqing jinwowo analysis blockchain technology is as follows:
1. Blockchain is a distributed database (system) placed in a non secure environment
2. The blockchain uses cryptography to ensure that the existing data cannot be tampered with
3, the blockchain uses consensus algorithm to reach consensus on new data
the system with the above three properties is blockchain.

2.

A: application fields of blockchain technology

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 the blockchain, we can rece the logistics cost, trace the proction and transportation process of goods, and improve the efficiency of supply chain management

Third, in the field of public service, blockchain is closely related to people's proction and life in the fields of public management, energy and transportation. However, the centralization of these fields also brings some problems, which can be transformed by blockchain

Fourthly, 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

In the field of insurance, insurance institutions are responsible for fund collection, investment and claim settlement, and often have higher management and operation costs

Sixth, the data stored on the public welfare field

blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios

A: the main application fields of blockchain technology are finance, Internet of things and logistics, public service, digital right, insurance and public welfare

First, in the field of finance,

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

Third, in the field of public service, blockchain is closely related to people's proction and life in the fields of public management, energy and transportation. However, the centralization of these fields also brings some problems, which can be transformed by blockchain

Fourthly, 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

In the field of insurance, insurance institutions are responsible for fund collection, investment and claim settlement, and often have higher management and operation costs

Sixth, the data stored on the public welfare field

blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios. The relevant information in the public welfare process, such as donation project, collection details, fund flow, recipient feedback, etc., can be stored on the blockchain, and can be made transparent and public, which is convenient for social supervision

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.

9. In fact, blockchain bill is an extended form of electronic digital bill. Before the proposal of blockchain bill solution, the situation of bill fraud and illegal transaction can not be effectively avoided. With the development of blockchain technology, the use of its own characteristics makes digital bill possible and makes up for some defects of bill market.
