Application of blockchain in steel trade

1. Absrtact: blockchain technology is the underlying technology of bitcoin. Without any centralized organization operation and management, bitcoin has been running very stably for many years (perfectly for seven years), and there has been no problem (no missing account). Therefore, some people have noticed its underlying technology and abstracted bitcoin technology, which is called blockchain technology, Or distributed ledger technology
what is centralization

the so-called centralization means "ownership" or ownership by the company. For example, Tencent's q-coin, which is issued by Tencent, is a kind of centralized electronic currency, including the total amount and the issuing method, is supervised and controlled by Tencent. You can use it, trade and go shopping, but you always have to operate in the framework of Tencent, and the final right of interpretation belongs to Tencent

the issuing mode of bitcoin is preset by the program and encryption algorithm, and runs on multiple nodes all over the world. No one or organization can modify it (everyone has his own account book, so it is impossible for one person to control everyone's account book at the same time. If there is such a technology, why should it be so complicated, If you want to blackmail money into your account, you will be the richest man in the world. There is no one left, And it is not controlled by any single person or organization
take an example: for example, Lao Zhang borrows 100 yuan from Lao Li, but Lao Li is afraid that he will default, so he asks the village head to do notarization and write down the account. This is called centralization. But if you don't find the village head, you can use the loudspeaker to shout in the village: "I Lao Li lent Lao Zhang 100 yuan! Please put it in the account book. "We all put this account in our own account book. This is called decentralization
anyone who transfers money between them will release information through loudspeakers. After receiving the information, everyone will record the transaction in their own account book. With distributed ledgers, it doesn't matter if Lao Zhang or Lao Li's ledgers are lost, because Lao Zhao, Lao Ma, Lao Wang and other families have ledgers

the main advantages of blockchain are that it does not need intermediary participation, the whole process is open and transparent, and the cost is low, and the data security is high

at present, blockchain is in a stage where everyone talks about blockchain, but can't perceive its actual technical charm. Since 2017, it has graally come into our sight, and we have graally realized that bitcoin is more fierce than real estate speculation (the price of mining machinery has skyrocketed! The news is on the screen But I still don't know

so, in which fields can blockchain be applied, what kind of changes will it bring to our future life

the core key: everyone has an account book, everyone has an account book, and the information recorded in each person's account book is consistent and synchronous, and the information is completely transparent. If it is fake, it will be the public enemy of the whole people, which greatly increases the cost of data fraud

core key 2: decentralization, which does not need a central system to manage data, prevents some people from changing data and damages the interests of the majority of people

Application:

1. Account security and privacy protection: currency transfer, exchange, payment system. Blockchain can help prevent data manipulation and fraud, prevent distributed denial of service attacks (DDoS), and effectively protect users' network privacy. Key words: anti counterfeiting, anti-counterfeiting, loan payment

2. Copyright regulation and interest disputes: for example, when a song is downloaded, from the author to the procer and then to the singer, they can get payment in real time through the blockchain, without having to wait for a long time like the traditional way, or even get no reward e to right disputes. Instead of waiting for publishers to provide royalty checks, creators can freely control the process from publishing to payment through blockchain application. Key words: real time receipt, no property dispute

3. Internet of things + artificial intelligence: the intelligent devices in the Internet of things based on the blockchain will be used to monitor the real-time situation of urban infrastructure such as bridges, roads, power grids, etc. the blockchain can connect these intelligent devices together for unified management to help them monitor more efficiently. This will help people better understand how to build a smart city in the future. Key words: unified monitoring, intelligent city

4: proof of existence: in life, once you are asked to prove that you are you, that your mother is your mother, that you have never been married, that the house belongs to you, and so on, things seem very simple. Once it falls on you, it is a great trouble. The application of blockchain technology can perfectly solve the above embarrassment. At that time, all the information that belongs to you will be recorded accurately and can not be tampered with. No one has the right to change it. When the technology develops to a certain stage, birth certificate and marriage certificate may be recorded on the blockchain. Keywords: no keywords

in addition to the application scenarios mentioned above, blockchain technology can also be applied to e-commerce, data storage, logistics and other fields. As long as we grasp the characteristics of blockchain technology, it will become easy to understand.

2.

Blockchain technology is widely used. Under the integration of new technologies, the main application scenarios of blockchain include finance and insurance, intelligent manufacturing, intelligent environmental protection, energy and power, health care, ecation, culture and innovation, smart city, social welfare, agriculture and many other fields

1. blockchain + finance

   blockchain can help financial institutions solve problems such as trust and data sharing

3. blockchain + right art

   Tianhe Guoyun's blockchain right system

3. Blockchain + government

in statistics, voting, budget management and other aspects, blockchain can rece costs, improve efficiency, and increase transparency, so as to prevent the risk of failure of centralized system

4. Blockchain + insurance

fraud identification and risk prevention: by placing insurance claims under an unchangeable general ledger, blockchain helps to eliminate the common sources of fraud in the insurance instry

property insurance and accidental injury insurance: policies and shared ledgers recorded in the form of smart contracts can improve the efficiency of property insurance and accidental injury insurance

Health Insurance: blockchain technology enables medical records to be encrypted and shared among health service providers, thus improving the interoperability of the health insurance ecosystem

Reinsurance: the information security of reinsurance contracts on the blockchain platform can be ensured through the form of smart contracts, which can rece the amount of information and simplify the payment process between insurers and reinsurers

3. Because the digital currency, which is the first generation of blockchain technology, has a huge impact on the financial field, the research and application of blockchain technology has become an important task in today's financial field. In essence, blockchain technology still belongs to a kind of technical means and tools. Its application in the financial field and the real economy is parallel. It has its own relative independence, but it also has a certain degree of intersection. That is to say, its role in promoting the real economy is indirect. 1. No matter in finance or entity, one of the bases of transaction between supply and demand is trust. The current bank to enterprise, enterprise to enterprise and enterprise to person are all linked by money. With the further popularization and wide application of blockchain technology, enterprises and enterprises, or indivials can issue digital currency (Digital credit) by themselves in the future, and the status of banks will change from monopoly operation to equal competition operation in the market. Therefore, the wide application of blockchain technology in the financial field has an indirect impact on the real economy. 2. Blockchain technology is the bridge between reality (entity) and virtual world. Through blockchain technology, the real world can be reconstructed, reconstructed and redefined in the virtual world. For example, the digital currency of real paper money in the virtual world, the digital stock transaction of real stock transaction in the virtual world, the digital settlement, digital customs clearance, digital documents and bills of real import and export trade in the virtual world can greatly improve the efficiency of business process and save the transaction cost. At present, all transactions are inseparable from the bank. The bank plays a central role in the transaction. The application of blockchain technology by the bank will certainly improve the efficiency of its settlement and indirectly promote the efficiency of the real economy, but this impact will graally weaken in the future. Because the biggest feature of blockchain technology is decentralization, its distributed accounting system is a network system without center. 3. In fact, the application of blockchain technology is to value and credit the information flowing on the Internet. Through the blockchain, the information with (use value, exchange value, cultural value) in the Internet is reorganized and newly constructed to form a value Internet. It is of great significance. It will bring revolutionary promotion to both the financial instry and the real economy.

4. Tourism instry: triporg travel is a blockchain tourism service application, which can provide people with hotel and other tourism services.

5. The third category of blockchain projects is application. Application projects are blockchain projects based on blockchain development platform (such as Ethereum), which can solve many problems in various fields of real economy
for example, AUR, Golem, vechain, omisego, which provides asset exchange and transfer services, is a prediction platform based on blockchain. Using blockchain technology, these projects can better solve the problems of trust and cross-border circulation. At the same time, using smart contracts and tokens on the blockchain, they can better realize automatic execution and greatly improve the efficiency of social and economic activities
Application blockchain projects cover a wide range of fields, including finance, social networking, games, property rights protection and so on. It is also the field where the market value of blockchain projects is growing fastest at present.
