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.
3. There are a lot of white papers on blockchain in the market, but most of them are based on the projects or procts behind them. This is probably how the white paper of Ansoft cloud comes from. It mainly introces its original research and development intention, application scenarios, technical analysis and so on. It can be seen on the official website of Zhongan technology. It's public and free of charge, As a basic course to understand blockchain, it's very good.
4. Professor Hu Kai's research mainly includes:
digital economy and blockchain Technology: he is one of the earliest scholars engaged in blockchain technology in China. He has proposed and developed such theoretical methods as smart contract engineering (SCE), legal code technology, verification as a service (VAAs), etc. in the fields of combination of digital economy and blockchain, planning and consulting of digital economic Park, digital governance of blockchain, and so on Blockchain scalability, Multi Chain interconnection and blockchain formal verification technology have in-depth research and patent achievements.

5. 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).
6. 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.
7. Search "blockchain" on HowNet to find model articles in this respect.
8. To understand the principle of blockchain thoroughly, we must understand it systematically from its birth and development, so as to distinguish the principle of blockchain more clearly from multiple perspectives. Block chain technology refers to the technical solution of collective maintenance of a reliable database in a centralized way in the past. In this technical scheme, blocks are associated by cryptography. Each data block contains all the data information of the system in a certain period of time, and generates a digital signature to verify the validity of the information, and links to the next data block to form a main chain< br />
Block is a record in the blockchain, which contains and confirms the transactions to be processed< br />
mining refers to the formation of new blocks through calculation. It is a process in which the supporters of the transaction use their own computer hardware to do mathematical calculation for the network to confirm the transaction and improve the security. Take bitcoin as an example: the transaction supporter (miner) runs bitcoin software on the computer and constantly calculates the complex cryptography problems provided by the software to ensure the transaction. As a reward for their service, miners can get the Commission included in the transaction they confirm, as well as the newly created bitcoin< br />
Peer to peer network is a system that allows a single node to interact directly with other nodes, so that the whole system can operate like an organized collective. Take bitcoin: the network is built in such a way that each user is spreading the transactions of other users. And importantly, banks or other financial institutions are not required as third parties< br />
Hash is a classical technology in cryptography, which transforms the input of any length into the output of fixed length composed of letters and numbers through Hassi algorithm< br />
Digital signature is a mathematical mechanism that allows people to prove ownership< br />
Private key is a secret data block that proves that you have the right to consume e-money from a specific wallet. It is realized by digital signature< br />
Dual consumption refers to the user's illegal attempt to pay e-money to two different payees at the same time, which is one of the biggest risks of e-money< br />

The origin of blockchain: an underlying technology supporting bitcoin
The concept of blockchain was first proposed in bitcoin: a peer-to-peer electronic cash system by Satoshi Nakamoto in late 2008. In this paper, block chain technology is the basic technology to build bitcoin data structure and transaction information encryption transmission, which realizes the mining and transaction of bitcoin. Nakamoto believes that: first, the mode of using third-party organizations to process information has the inherent weakness of lack of trust between points. In order to guard against their customers, businesses will ask customers for completely unnecessary information, but still can not avoid certain fraud; Second, the existence of intermediaries increases the transaction cost and limits the practical minimum transaction scale; Third, digital signature itself can solve the problem of e-money identity. If the third party support is needed to prevent double consumption, the system will lose value. Based on the above three existing problems, Nakamoto Cong has created bitcoin on the basis of blockchain technology< br />
On January 3, 2009, Nakamoto proced the first bitcoin block in the world, genesis block, and excavated 50 bitcoins< br />
On May 21, 2010, Florida programmers bought $25 worth of pizza coupons with 10000 bitcoin, which gave birth to the first fair exchange rate of bitcoin< br />
In July 2010, the first bitcoin platform was established, with a surge in new users and prices< br />
In February 2011, the price of bitcoin reached US $1 for the first time. Since then, exchange trading platforms with British pound, Brazilian real and Polish zloty have opened< br />
In 2012, ripple released that as a digital currency, it uses blockchain to transfer foreign exchange of various countries< br />
In 2013, bitcoin soared. The U.S. Treasury Department has issued the regulations on the personal management of virtual currency to clarify the definition of virtual currency for the first time< br />
In 2014, the mining machinery instry chain represented by China became more and more mature. In the same year, the U.S. it community realized the cross era innovation significance of blockchain in the digital field< br />
In 2015, the US Nasdaq Stock Exchange launched LINQ, a digital ledger technology based on blockchain, to record trading and issue stocks
the principle of blockchain can be understood clearly from each application case, and the application of blockchain principle is becoming more and more popular. Recently, Citigroup, Mitsubishi UFJ Financial Group, UBS and Deutsche Bank will also apply "blockchain" technology to build a fast, convenient and efficient blockchain Low cost trading system. In addition to the financial field, blockchain technology has also begun to be applied to the protection of intellectual property rights, notarization by lawyers, online games and other fields where there is a need for transparent information disclosure and permanent records.
