Data format specification for blockchain of MIIT

1. The explanation of MIIT is as follows: blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing paradigm to program and manipulate data by using smart contracts composed of automated script code
take an example: for example, Sun Tzu asked Li Zi to borrow 100 yuan, but Li Zi was afraid that he would default, so he asked the village head for notarization and added the account. This is called centralization. But if you don't ask the head of the village, you can shout "I'll lend my grandson 100 yuan! Please put it in the account book. "This is called decentralization
in addition, you can refer to bitcoin, the representative proct of blockchain

2. How hot is the blockchain? Even my mother knows this word, and many people around me also ask me about it
in fact, their real idea is to know how to make money. After all, how much has bitcoin gone up in recent years when all kinds of information came out on the Internet, and to what extent has blockchain become popular today, Internet companies in all halls have joined in. As ordinary people, they also want to splash in this "pond"

so what is blockchain< In a broad sense, blockchain technology is to use blockchain data structure to verify and store data, use distributed node consensus algorithm to generate and update data, and use cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing paradigm to program and manipulate data by using smart contracts composed of automated script code
in short, blockchain is a decentralized distributed ledger database. Decentralization is different from the traditional way of centralization. There is no center, or everyone is the center; Distributed ledger database means that the recording method is not only to store the ledger data in each node, but also to share and the data of the whole ledger synchronously. At the same time, blockchain also has the characteristics of disintermediation and information transparency
let's give an example. For example, in our usual online shopping, after placing an order, our money will be transferred to the intermediary platform of the third-party payment agency. After the seller delivers the goods and the buyer confirms the receipt of the goods, the buyer will inform the payment agency to transfer the money to the seller's account
however, the transaction mode supported by blockchain technology is different. Buyers and sellers can trade directly without any intermediary platform. After the transaction between the buyer and the seller, the system publishes the transaction information in the form of broadcast, and all hosts receiving the information record the transaction after confirming that the information is correct, which means that all hosts have done data backup for the transaction. If there is a problem with the orders proced by this machine, its data information will not be affected, because there are countless machines backing up data at the same time
when it comes to blockchain, we have to mention bitcoin, as if you don't understand anything without putting the two together
in fact, although blockchain is a blockchain and bitcoin is bitcoin, most of the people concerned are
concerned about bitcoin, and not many people are concerned about blockchain. Even if he says that he is concerned about the chain, in fact, that is to make do with the excitement. What the other party is more concerned about is which kind of currency makes more money. How can I join in
in fact, what I want to say is that you don't have to catch up with every outlet. If you don't catch up with the stock market, we media, wechat business and artificial intelligence, so will the blockchain. New procts will soon replace it
What's the role of blockchain in making people so obsessed? Let's take the above shopping example to illustrate that the so-called bilateral transactions are not absent now, but they are both bilateral transactions. What if one of them does not deliver the goods to you after receiving the money, or if he does not accept the account after receiving the money
How can blockchain solve this problem
it's also a transaction, but in the process of transaction, everyone knows that the other party has given you the money, and you can't deny it. In the final analysis, it's a matter of credit value
what can blockchain bring us? Once there was such a news in the society that how to prove that your mother is your mother. Even if we have the ID card account book in our hands, we still need a government agency to identify it, which is cumbersome
with the help of the regional payment chain, we can establish credit with low cost through mathematical principles rather than centralized credit institutions. In this way, our birth certificate, household register and real estate certificate can be verified on the blockchain. Your mother is your mother's problem
another example is the food safety problem that has been implemented at present, and the rookie tmall Jingdong has started to use it. With the help of blockchain technology, a reliable mechanism has been established for all transactions, which enables procers, suppliers, processors, distributors, retailers, regulators and consumers in the food chain to obtain the source and status information of food at any time, so as to facilitate the tracking of contaminated food, accelerate the removal of problem food from shelves, and effectively prevent the spread of food safety problems
when consumers buy food, they can easily see where the food they eat comes from, how long it has been proced, and what fertilizer they have applied. For the arrival of blockchain, whether we are ready or not, we still have to see if we are not ready

3. Let's talk about the social or economic significance of blockchain. In fact, many of the previous technologies were devoted to "proctivity". For example, artificial intelligence is a kind of progress in proctivity. The blockchain, which has greatly improved the proction relations, is committed to the proction relations. So why do you say that
because the so-called proction relationship is actually how to do business between people and business partners. And these things, originally, are in the cognitive process between people, and there is no special program to program or quantify it
for example, if you and I are good friends now, we can do business. If someone stirs up our relationship and we are not good friends, we will not do business. Even if we can make money in business, we will not do business because there is no trust between us
as for blockchain, it is actually because the data is authenticated by all nodes and backed up at the same time, so my data is as real as possible and can't be tampered with. In this case, if you believe my data, you can make a program on this basis, and then use the data to make what kind of business contract, what kind of service, what kind of service, and what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, etc This "proction relationship" of commercial cooperation is programmed. In this way, we believe in the data and the program compiled by the algorithm. Because you believe in the data and the program, you can develop all kinds of apps in the program. These apps are the proction relations and what business to do. This is: blockchain is actually a reconstruction of "proction relationship".

4. Blockchain Technology Application Research Center is an institution directly under the blockchain Technology Application Research Institute.
the blockchain Technology Application Research Institute was established in Zhengzhou City, Henan Province under the policy guidance of the Ministry of Commerce, the Ministry of instry and information technology and the Ministry of science and technology.

the blockchain Technology Application Research Institute will support 1000 Central Plains enterprises to implement blockchain technology application within two years by docking with one billion capital resources, so as to help the Central Plains economy to overtake.

5. For a long time, medical institutions have to enre the inability to share data safely on various platforms. Better data cooperation between data providers means more accurate diagnosis, more effective treatment, and improving the overall ability of the medical system to provide cost-effective medical services. With blockchain technology, everyone's medical data will be saved in a dedicated electronic system, and there is no need to worry about the security and integrity of the data
in the future, jinwowo will continue to tap the value of blockchain technology in the commercial field.

6.

belongs to the information instry, blockchain is a distributed digital ledger, which records all the transactions that have occurred and have been unanimously recognized by the system. Each block is like a hard disk, which saves all the above information, and then encrypts it through cryptography technology. The stored information cannot be tampered with

can be applied in different fields, as follows:

1. In the financial field

blockchain has great potential value in international exchange, letter of credit, equity registration, stock exchange and other financial fields. The application of blockchain technology in the financial instry can save the third-party intermediary link and realize the point-to-point direct docking, so as to greatly rece the cost and quickly complete the transaction payment

2. 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. This field is considered as a promising application direction of blockchain

extended data

characteristics and development planning of blockchain

I. characteristics

1. The biggest feature of blockchain technology is to create an integrity system of digital society. In this system, not only data transmission is convenient, but also counterfeiting is difficult

2. Another feature of blockchain technology is that it can realize the timely sharing of data and can not be tampered with. In the field of government services, the use of blockchain data sharing mode can realize the joint maintenance and utilization of government data across departments and regions, promote business collaboration, and facilitate the masses to handle affairs

2. Development planning

major countries in the world are speeding up the development of blockchain technology, and China has a good foundation in the field of blockchain

the 13th five year National Informatization Plan issued by the State Council, the 13th five year development plan for information technology of China's financial instry issued by the people's Bank of China and the white paper on China's blockchain technology and application development led by the Ministry of instry and information technology all clearly put forward the need to strengthen the basic R & D and frontier layout of blockchain technology, The standardization roadmap of blockchain technology development in China is proposed

7. Legal and effective electronic contracts are all signed on the third-party electronic signature platform based on digital certificate technology. Digital signature electronic contract adopts rsa2048 public key algorithm and sha256 signature algorithm. The digital signature provided is safe and reliable, can not be cracked, and truly ensures the security, credibility and non tamperability of signature results. It is suggested to go to wosigndoc E-contract signature platform to learn about it.

8. The LAN port of the main router is connected to the WAN port of the secondary router, and the access mode of the secondary router is usually set to obtain IP dynamically. Note: the LAN port IP of two routers cannot be in the same network segment.
