Application of blockchain in industrial control

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.

The biggest feature of blockchain technology is decentralization, which will rece a lot of costs for the banking instry

First of all, decentralization means that the trust building mechanism between banking systems no longer needs intermediary, which saves the cost of intermediary

Secondly, the development of digital currency will realize the real-time digital transaction of banks. For example, in bill transaction, bank's bill transaction always relies on the third party to realize the transfer of valuable documents. Even for electronic bill transaction, it also needs the information of central bank's ECDs system for mutual authentication. The blockchain technology can realize the point-to-point value transmission, which no longer needs centralized system control. This not only speeds up the bill transmission speed, but also reces the mistakes caused by human factors. The rection of process will naturally rece the demand of the bank for personnel and save the labor cost of the bank

finally, it will also have an impact on clearing and settlement. The bank's clearing and settlement business has always been completed by the central settlement, with low efficiency. Settlement through blockchain technology will greatly improve the efficiency of banks

blockchain technology also plays an important role in the cross-border payment business of banks. Today, with the highly developed global trade, cross-border payment is becoming more and more frequent. Banks often act as third-party services in cross-border trade, such as electronic transfer, asset custody and so on. However, cross-border payment generally takes about two days to get to the account, which is inefficient and reces the utilization rate of funds in transit. In the blockchain technology, both sides of cross-border payment can complete through the point-to-point way, realize all-weather payment and real-time arrival, thus speeding up the speed of clearing and settlement, and improving the efficiency of bank business processing

another feature of blockchain technology is de risking. Banks can establish their own blockchain, which can ensure that the transaction information and transaction records of bank customers are true and effective, and will not be tampered with arbitrarily. Banks can effectively identify customers' information, understand all aspects of customers' situation, identify abnormal transactions of customers, and prevent being cheated by customers, So as to rece the cost of bank supervision

China's blockchain instry ecology has initially taken shape, and the number of enterprises has increased rapidly. According to the white paper on China's blockchain instry in 2018 previously released by the information center of the Ministry of instry and information technology, as of the end of March 2018, the number of blockchain companies with blockchain business as the main business in China has exceeded 450, and the instry has initially taken shape

the Ministry of instry and information technology proposes that the blockchain instry is still in the initial stage, and the positive value of technology is graally emerging, but there are still risks that can not be ignored in the development process, such as challenges to the current system and norms, technical loopholes, etc. The Ministry of instry and information technology proposed that it will accelerate the innovation and application of blockchain technology, especially strengthen the improvement of computing capacity, storage capacity and integration penetration capacity, build a good instrial ecology, and promote the healthy development of blockchain instry

4. In the instry, jinwowo Group believes that with its unique trustworthiness, security and non tamperability, blockchain technology liberates more big data and further promotes the massive growth of data

the traceability of the blockchain enables the records of every step of data collection, transaction, circulation, and calculation and analysis to be kept on the blockchain, which makes the quality of data obtain unprecedented strong trust endorsement, and also ensures the correctness of data analysis results and the effect of data mining

it can be said that blockchain is another epoch-making breakthrough in the Internet instry in terms of cloud computing and big data technology.

5. Xu Mingxing believes that with the rapid development of the current manufacturing instry, there will be more and more information physical systems in this field. These systems will proce a large amount of data, which is a great test for the transmission channels and processing equipment. Blockchain technology has a decentralized point-to-point communication mode, which can efficiently process the exchange of a large amount of data, Recing the cost of maintaining large data centers is the advantage of blockchain technology in the manufacturing field.

6. Chongqing jinwowo network analysis: the blockchain distributed accounting system can be used to track the source of goods
for example, for food, the system based on blockchain technology can show consumers the source and processing process of food.
