Analysis on application mode of blockchain charity

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.

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

3. Several successful ones are block chain housing rental platform in xiong'an New District, SMIC block chain public service platform in Changsha high tech Zone, and block chain Real Estate Registration Platform in Loudi. Hunan has done a good job in the application of block chain technology in the whole country. There are mature and successful application cases in provincial capitals and prefecture level cities.

4. Try changing a computer, a USB interface, and a data cable.
I know so much. I hope I can help you. If I can't, I can only try changing an MP3

5. Let's not talk about the advantages of blockchain public welfare. Just imagine how public welfare and charity organizations manage donations without a good supervision mechanism. Many people's first reaction should be that donations can't be traced and information is not transparent
blockchain technology + public welfare does not need third-party supervision, which reces the management cost. Secondly, donations can be managed by directly recording transaction data in the blockchain. Zhongan's firepile public welfare with blockchain technology is in this form
I can't be sure, but I have solved those uncertain problems before.

6. Mr. Hu Zheng, director of China Merchants Group and executive vice chairman of China Merchants charity foundation, explained the public welfare concept of the project, saying that public welfare projects are not simply given and presented, but also need to have a global perspective, and combine the needs of social transformation and the application of scientific and technological innovation. Under the background of global energy transformation and climate challenges, Shekou energy blockchain is a public welfare attempt to join hands with partners, rely on blockchain technology, and drive more public to participate in climate change action with practical actions.

7. Good question
here, I can only briefly talk about two uses that I can think of. As for how to realize it, I suggest the subject to study the principles and technical details of blockchain in depth
the financial transparency of charitable organizations is often misunderstood and suspected by the public. You may suspect that money is not spent where it should be, or that there are places where it is spent indiscriminately
1) if you use blockchain, you can easily record and track the actual use and source of each payment. For example, a donated 1000 yuan, and the charity split the 1000 yuan into several donations to different people. Using the blockchain, it is very convenient to record where each piece of money donated by a goes. At the same time, the recipient's money, each piece from who can be recorded
2) using blockchain can avoid malicious tampering with financial data. Because deleting blocks and modifying blocks are easy to find. There will be no hiding place for false accounts
of course, other technologies are needed to achieve these goals.

8. This is a political issue, not a technical one
if the money in the public account of a bank wants to be publicized, it can also be publicized, so why doesn't it be publicized< Make complaints about br / > block chain
