MPA paper blockchain

1. Development status: now it should be everywhere, from the first tier cities to the third and fourth tier cities have relevant application cases. For example, the tax chain platform in the first tier city of Guangzhou, the SMIC blockchain public service platform in the second tier city of Changsha, and the blockchain electronic deposit certification platform in the third tier city of Haikou. Detailed network search can be done. Changsha, the SMIC platform, is a relatively comprehensive blockchain + government + public service platform.

2. Can you write it into the passers-by of data structure and blockchain into the paper of data structure.

I have seen your question. In which aspects can blockchain be applied? Below by the small series to answer for you

bitcoin is the first specific application of blockchain. It was proposed in a paper by one person or a group of people in 2008. Bitcoin uses blockchain to send digital messages to bitcoin, and the name of bitcoin is bitcoin, without the intervention of a third party middleman

However, bitcoin is not the only application of blockchain, as follows:

1. Financial field: the application of blockchain technology in the financial instry can eliminate the third-party intermediary link, realize the point-to-point direct docking, so as to greatly rece the cost and quickly complete the transaction payment

2. 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

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

4. 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

5. In the field of insurance claims, insurance institutions are responsible for fund collection, investment and claims settlement, and often have higher management and operation costs. Through the application of smart contract, there is no need for the applicant to apply or the insurance company to approve. As long as the claim conditions are triggered, the automatic claim settlement of the policy can be realized

6. Public welfare field: the data stored on the 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

the above is for your reference only, hope you can adopt it, thank you

4. Hu Kai's graate degree course distributed operating system. In recent years, he has published more than 60 SCI / EI retrieval papers in important academic journals at home and abroad, edited new technologies of network computing (416 pages, published by Science Press in 2001), and completed the national "Eleventh Five Year Plan" textbook introction to distributed computing system (490 pages, published by Tsinghua University Press in 2014).

5. A timestamp, usually a sequence of characters, uniquely identifies the time of a moment. Digital time stamp technology is a variant of digital signature technology. In the blockchain, timestamp means that whatever happens at a certain time will be recorded on the blockchain.

6. Search "blockchain" on HowNet to find model articles in this respect.
