E-commerce platform's own virtual currency
It's not illegal
For example,
-
the virtual currency represented by bitcoin is legal in China, which is defined as a special Internet commodity, and people can buy and sell freely at their own risk
-
but it is illegal to carry out pyramid schemes under the guise of bitcoin. Now to create a virtual currency trading platform, we must record the website and implement real name authentication for users
-
bitcoin is legal in most countries around the world, except that some small countries explicitly prohibit bitcoin

since 2003, the more popular virtual currencies are bitcoin, Laite coin, Fuyuan coin, doggy coin, Diablo coin, reborn coin and so on
moreover, these so-called virtual currencies are basically empty handed projects with white wolves, and the application scenarios of their publicity are also non-existent and unreliable. These currencies are different from the mainstream digital currencies such as Ruitai, bitcoin and Leyte.
first of all, websites that accept bitcoin payment need to cooperate with coinbase. There is an account on it. When a buyer uses bitcoin to pay, these coins will be automatically transferred to the account of the platform, which can be sold directly according to the market price, and the platform can directly transfer the exchanged legal currency to the merchant. In short, bitcoin is just an intermediary, and businesses still accept legal money
other digital currencies can do the same, such as Swiss Thai dollar, thousand gold card and so on. However, the price of these digital currencies is not very stable, and the risk of merchants accepting digital currency payment is relatively high.
at present, more than 60% of bitcoin computing power is in China, and more than 60% of transactions are in RMB. China occupies a leading position in bitcoin and other virtual currency markets. Most virtual currencies also have Chinese figures. For example, Li Qiwei, the founder of lightcoin, is a Chinese American. The Yuan Bao coin, Fuyuan coin and Zhaocai coin made in China are also authentic. Zeng Hongji's bitstock is also the project of Li Xiaolai
but it is worth noting that most of the research on virtual currency is not in China, and bitcoin related financing also occurs in European and American countries. European and American countries pay more attention to infrastructure construction and R & D, focusing on the future rather than immediate interests.
Take a few examples of blockchain applications
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 there is no need for intermediaries to establish trust mechanism between banking systems, which saves the cost of intermediaries
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 bankfinally, 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
< UL >blockchain technology also has incomparable advantages in the insurance instry
from the perspective of data management, the application of blockchain technology by insurance companies can effectively improve the ability of risk management and control, including the risk supervision of insurance companies and the risk management of policy holders
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
in addition, the blockchain technology is safe, reliable and can not be tampered with at will, which ensures that the information obtained by the policyholder is true and effective, and enhances the risk management ability of the policyholder
< UL >the application of blockchain technology in the securities instry can increase the flexibility of securities issuance
companies that issue securities can adopt smart contracts. By setting the way and time of securities issuance, they can even issue securities 24 hours in the most ideal state
under the operation of the smart contract, the buyer and the seller are automatically paired, and the settlement and clearing steps are automatically completed through the distributed digital registration system. The transaction records on the blockchain will not be changed casually, so the information entered has the effect of publicity in practice, so there will be no dispute about the confirmation of ownership in the stock exchange
in addition, blockchain technology makes the securities trading process more open and transparent. Through the blockchain technology, the securities instry does not need core institutions to operate and manage, nor does it need investment banks to underwrite, so as to achieve real point-to-point transactions, rece the illegal activities such as the black box operation and insider trading in securities trading, and realize the effective supervision of the securities instry
< UL >blockchain technology is a decentralized mechanism for value exchange, which will lead to earth shaking changes in the existing financial infrastructure characterized by centralization
collateral, pledged goods, stocks, bonds, derivatives and other assets usually need a trusted core institution to register or keep, while blockchain can record and save the data of these procts in a new way, which will have an impact on the registration system of these procts
through smart contracts, blockchain can receive and respond to information and value, automatically complete the transfer of value, and automatically complete the transaction, clearing and settlement, which will impact the existing financial infrastructure such as the existing large value trading system, securities depository, securities settlement and OTC derivatives trading
the application of blockchain technology in the supply chain, first of all, provides a credit guarantee. The circulation information of commodities is recorded on the blockchain, which can prove the authenticity and reliability of commodities and their circulation, so as to make a comprehensive evaluation of the effectiveness of enterprises on the chain, and become an effective guarantee for enterprise bank loan credit, financing credit and transaction credit
first of all, blockchain can time stamp all the transaction data in the supply chain, which can not be tampered at will. Even if it can tamper with the transaction data of a node, it can not cover the sky with only one hand. Therefore, blockchain solves the banks' doubts about the tampering of enterprise information. For some small and micro enterprises, as long as their credit is good, the possibility of lending to banks will be greatly improved
secondly, through effective integration, the information between upstream and downstream enterprises recorded in the blockchain can not only provide support for enterprises in proction, sales and other links, but also for downstream enterprises to analyze customer preferences, so as to develop targeted services
One kilogram equals 2.20462262 IB, and one pound equals 453.59237 G
one pound force is 4.4482 Newton, the acceleration of gravity is 9.8067, one kilogram is about 2.2046 pounds, one pound = 0.45359 kg, that is 453.59 G
In the engineering unit system, pound force represents the gravity of a pound at sea level of 45 degrees north latitude, which is g = mg, g = 9.80665 n / kg, 1 pound = 0.45359237 kg, so 1 pound force = 4.4482216152605 n, But now the ratio of gold price to gold weight has become a relationship that can float freely. In the European and American test questions, if the writing is 200lb, it means the size of a force; if the writing is 200lbs, it means the quality
extended data
