The function of virtual currency in E-commerce

4.

the impact of virtual currency on e-commerce is as follows:

1. the impact of virtual currency on the financial system

2. the network security of virtual currency

3. inflation in the virtual world

5. This is actually very simple. There are many third-party bitcoin payment processing companies at home and abroad, such as bitpay and coinbase. Let's take coinbase as an example:
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.

6. Blockchain technology is a decentralized consensus mechanism to maintain a complete, distributed and tamperable ledger database. It can enable the participants in the blockchain to achieve a unified ledger system without establishing a trust relationship
in the future, blockchain will be applied in any field and bring great impact on human life. Blockchain technology is regarded as one of the main protocols of the next generation of value Internet. Blockchain technology will be useful in any field of proction and life that lacks trust. From digital currency to securities and financial contracts, health care, games, artificial intelligence, intelligent contracts, Internet of things, identity authentication, asset trading, e-commerce, social communication, file storage and other fields can be widely used
in the aspect of medical treatment
when the blockchain technology is used to save the personal medical records, there will be the historical data of personal medical treatment, which can be understood as the electronic medical records on the blockchain. In the future, there will be data for medical treatment or health planning, and the real master of this data is the patient himself, not the hospital or a third-party organization. In addition, these data have strong privacy, and the use of blockchain technology also helps to protect the privacy of patients
payment system
compared with the existing traditional payment system, blockchain technology can avoid the complex system, directly between the two sides of the transaction, does not involve intermediary institutions, even if part of the network is paralyzed, it will not affect the operation of the whole system. This method has the characteristics of low price, fast speed, and no intermediate fees
banking
as a digital, secure and anti-interference account, blockchain realizes the core function of Banking: the safe storage and transfer center of value. Some banks with keen sense of smell in the world have begun to actively plan to join the army of blockchain research and application in order to gain the initiative in the fierce competition in the future
identity authentication of blockchain
blockchain has the feature of being accessible to everyone. Everyone can query the block information in any place with network. The high transparency also makes blockchain full of charm. In the future, ID card and account book are basically not needed, because every identity information can be written into the blockchain. When you need to verify the information, you only need to look it up to find it
election
based on the voting transaction on the blockchain, it can be confirmed that no vote has been modified or deleted, and there will be no improper voting
Real Estate
blockchain technology can change the operation mode of the real estate market. It can combine many complex processes and cases that real estate companies usually deal with, speed up the transaction process, rece fraud, and provide more transparent and secure transactions for each participant. Provides a way to achieve paperless and fast trading needs
securities issuance and trading
the probability of various kinds of errors in general stock and other securities trading is too high, which requires manual correction, thus prolonging the time required for transaction settlement. Through the transaction of distributed ledger, the automation of the whole process can be realized, and the security and efficiency can be improved. The identity and transaction volume of the trading party are recorded on the blockchain in real time, with an open, transparent and traceable system. It is concive to the market maintenance of securities issuers and regulatory authorities, and can rece the occurrence of black box operation and insider trading
in the scenario of relatively closed, multi-party trust problems and carrying value transmission, blockchain has unique technical advantages and also shows unique charm, which has great application imagination space. At the current stage, blockchain is worth exploring in some scenarios.

7. If your watch has not yet passed the warranty period, it is generally recommended that you take it to a specialty store or a special after-sales service center for warranty. If your watch has passed the warranty period, you can also choose to get some professional large-scale watch repair shops to repair it
you can get Guangcheng watch bank and ask Shifu to help you find out what the problem is
many people think that a watch is not waterproof. Why does it get into the water? The higher the waterproof coefficient, the more difficult it is to get into the water, but it doesn't mean it won't get into the water. Many people have misunderstood it. If you wear a watch for two years, and don't go for maintenance, it's normal to get into the water when you take a bath or swim, Because the waterproof rubber ring of our watch will oxidize slowly with time. Usually, if the watch is not maintained, the waterproof ring is not replaced, and the waterproof test has not been done, the waterproof performance of the watch will graally weaken
if you wear a watch for a long time, such as bathing, diving and swimming, it is recommended to test the waterproof performance of the watch every year.

Take a few examples of blockchain applications

< UL >

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

< / UL >

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 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

blockchain technology also has incomparable advantages in the insurance instry

< / UL >

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

< / UL >

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

< / UL >

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
