Literature review of blockchain targeted poverty alleviation

1. Guizhou has released some standards, such as the quality model and key elements of blockchain system, the implementation process of data asset transaction of blockchain, the terminology and basic requirements of the implementation process of targeted poverty alleviation of blockchain, etc. now many local blockchain applications have been implemented. Our digital money package is also an application of blockchain technology, and now blockchain applications have been implemented one after another, Changsha high tech Zone has launched a SMIC blockchain service platform project, which is based on the blockchain + public service mode, and is soliciting enterprises to join the chain.

2. 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.

3. Nowadays, we all advocate the development of smart countryside. Blockchain technology naturally has the characteristics of credibility, transparency and non tampering. It is highly compatible with business scenarios such as proct traceability, storage confirmation and data sharing, and can provide solid and reliable technical support for the quality and safety traceability of agricultural procts. In recent years, blockchain technology has been successfully applied to agricultural traceability, targeted poverty alleviation and other fields, and has achieved remarkable results.

4. Blockchain technology supports the development of real economy and can be applied to all walks of life. In the field of people's livelihood, such as targeted poverty alleviation, medical care, pension, food security and government services. Secondly, in the real economy, it can rece the financing cost of enterprises and solve the problems of financing difficulty and high financing cost of small and medium-sized enterprises. Blockchain is now combined with the development of various instries. A SMIC blockchain service platform project initiated by Changsha high tech Zone is a blockchain + public service mode, and enterprises are being recruited to join the chain.

5. Traditional heavy-ty shelves on the chain is not convenient to operate, there is not much space
at present, blockchain technology has been applied in more than ten cities such as Beijing, Guangzhou, Shenzhen and Shanghai. In the aspect of government affairs, it is mainly used in government data sharing, data collection supervision, Internet financial supervision, electronic invoice, etc; In terms of people's livelihood, it is mainly applied to targeted poverty alleviation, personal data services, medical and health data, smart travel, social welfare services, etc; The application of finance mainly involves supply chain finance, cross-border payment, asset management, insurance and other sub fields.

6. Money is like stocks. Currency speculation is the lowest threshold for blockchain to make money. You are most familiar with bitcoin. Bitcoin has risen 40000 times since its birth. In addition to bitcoin, there are also many digital currencies, such as Ethernet currency and so on. Currency speculation is divided into primary market (ICO) and secondary market (exchange). The primary market is like an angel round investment for a certain project, which is generally played by experts; The secondary market is to go to the exchange to buy money, just like buying stocks, low in and high out.
