Common sense of blockchain exchange
you mean platform trading. Domestic illegal, international and mostly deceptive, you find the well-known ones. There is a special introction to blockchain network. Remember to be legal, otherwise you can't withdraw cash and it's useless to make money.
1. Application of blockchain technology in the banking instry the biggest feature of blockchain technology is decentralization, which will rece a lot of costs for the banking instry. The development of digital currency will make it possible for banks to realize real-time digital transactions. For example, in bill transaction, bank bill transaction always relies on the third party to realize the transfer of valuable documents. Even in electronic bill transaction,
also needs to be authenticated through the information of central bank ECDs system. 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
2, the application of blockchain technology in the insurance instry
blockchain technology also has incomparable advantages in the insurance instry. From the perspective of data management, the application of blockchain technology can effectively improve the risk management and control ability of insurance companies, including the risk supervision of insurance companies and the risk management of policyholders
the application of blockchain technology in the insurance instry can strengthen the internal risk supervision of insurance companies. Blockchain technology can record the daily operation process of insurance company on the node, realize the in-process control of the company's capital flow, investment situation, compensation amount and other business, and improve the company's risk management and control ability
3. Application of blockchain technology in the securities instry
4, blockchain technology and financial infrastructure
blockchain technology is a decentralized mechanism for value exchange, which will lead to earth shaking changes in the existing financial infrastructure characterized by centralization
5. Application of blockchain technology in supply chain, It has become an effective guarantee for enterprise bank's loan credit, financing credit and transaction credit
codewords are not easy, please adopt them!
Let's suppose villagers Lao Wang and Xiao Li. Lao Wang borrowed some money from Xiao Li, who wrote it in an IOU signed by both parties. A few days later, Lao Wang denied the existence of borrowing money and claimed that Xiao Li forged the paper. Xiao Li can't argue because he finds it difficult to prove that Lao Wang actually owes him money
in this example, Lao Wang and Xiao Li are two nodes
now assuming the same scenario, there are many pairs of people trading with each other in the village. The only evidence for each pair is the IOU. If one party fails, it will be difficult to do so. Seeing this scene, the village head came up with a solution. He suggested using a common notebook for the whole village to record all the transactions. Due to the high prestige of the village head, the villagers unanimously decided to let the village head keep this important transaction book. Each transaction, the villagers go to the village head's home, let the village head witness and record, each transaction is written into a notebook, and then safely saved. That notebook can be called a database
because this notebook is very important, the village head locked it in the safe. However, there are always some problems. Sometimes, the village head will accidentally sprinkle ink on the paper, making some transaction records illegible. This is called a single point of failure. The thief knows that there is an important notebook in the safe of the village head's house. He tries his best to steal it. This is called hacking
until one day, the village head's son owed others a lot of money, so the village head secretly deleted his son's debt entry. In this way, the village head's son "does not owe money."
when the villagers knew this, they began to question the fairness and authority of the village head. So some people put forward a new idea:
abolish the power of the village head, which is called decentralization. Let all villagers keep a notebook, and the transaction records are copied and distributed, which is called distributed database. Therefore, if there are n people in the village, there are n notebooks, that is, n nodes. Every time there is a trade between any two people, all the people in the village get together and record it in their notebooks. And no one can cover the sky. This is called decentralization
they also decided that they would never delete the mentioned transactions from their notebooks, which is irreversible. For example, Lao Wang borrowed a sum of money from Xiao Li before, but in the twinkling of an eye, he wants to return the money. Then the transaction book will not delete the previous borrowing record, but write a new repayment record, so there are two records
next, let's try to break this rule. What if we bribe Lao Wang to change his notebook? It's not feasible, because the next time the villagers meet, they find that Lao Wang's notebook is different from everyone else's, so the villagers notice that Lao Wang may be engaged in an indescribable transaction, and decide to abolish Lao Wang's transaction record and kick Lao Wang out of the organization
What if you try to bribe all the villagers? It's too expensive
the characteristic of this model is that greedy people need to pay a lot to attack the rules. He will find it more profitable to follow the rules
a smart child in the village suggested that each transaction data be called "block" and linked into a "chain" in chronological order, which is called blockchain
in a narrow sense, blockchain is a kind of chained data structure, which is composed of data blocks connected in sequence according to the time sequence, and is a distributed account that can not be tampered with and forged by cryptography. In a broad sense, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
blockchain and big blockchain are not the same concept. Big blockchain should be the name of a company. Bitcoin, Ethereum and decent are all successful cases of blockchain technology.
any investment has certain risks. Digital currency is the trend, and the currency circle routine is also very deep. Blind buying is too risky. It's better to consult more professional people before buying
it's not recommended for novices to invest too much money to play. It's better not to play. To tell you the truth, it's all played by institutions, information sources, situation judgment, entry time and exit time, which are not comparable to novices and retail investors. There are nearly ten million coins on hand, but they are just one kind of currency. Once they reach their expectations, they will do it collectively. There are risks in investment, so we need to be more cautious in playing currency
bitcoin is unreliable
musk openly discusses the conversion of assets, but it is only limited to the discussion session, which shows that musk himself is still on the sidelines. We must not buy a lot of bitcoin at this time, otherwise we will suffer losses first, bitcoin is a virtual asset of the network. That is to say, without the Internet, bitcoin would be worthless moreover, the value of bitcoin is like a stock, which is not stable and suitable for asset conversion. It's very likely that the price of bitcoin will drop as soon as the conversion is over and the most important thing is that the bank is responsible for the value of RMB, but no one can be responsible for the value of bitcoin. If bitcoin immediately drops to nothing after the end of asset conversion, no one can be responsible at this time
In the second half of 2018, China's auto market fell sharply, and there was no improvement in the first quarter of 2019. In such an environment, many auto companies are looking for ways to cross the cold current. The 2019 Shanghai auto show, which is being held, has become an important stage for auto companies to show their strength. Although Shanghai auto show is called auto show, it can also be called science and technology show in fact. Especially with the addition of 5g, intelligent Internet connection and automatic driving technology have become the mainstream direction for auto companies to flaunt the future and represent the cutting edge. Intelligent technology brings new experience{ RRRRR}
autonomous driving leads the future. At Shanghai auto show, many auto companies have tacit understanding to apply the realizable L3 level automatic driving technology to the officially launched or upcoming new models, and apply L4 and L5 level automatic driving technology to the new concept models. The new generation of Mercedes Benz S-class will introce the automatic driving technology of Mercedes Benz Level 3 for the first time, or allow the driver to let go completely. GAC aion LX holds L3 level automatic driving function. Among the new forces, Xiaopeng P7 is equipped with autopilot chip, with L3 level autopilot capability; The quasi mass proction model of Zero run automobile appears, which can realize L3 level intelligent driving function. The new car represents the planning of the present stage, while the concept car reflects the enterprise's thinking and forward-looking layout of the future car. The concept cars supporting L4 level automatic driving function include ID. roomzz of Volkswagen, AI: me of Audi, vision inext of BMW and IMS of Nissan. In addition, L5 automatic driving technology is rarely demonstrated.
