Why do digital currencies need exchanges
as we all know, digital currency is based on blockchain technology and platform, and it is also one of the most typical applications of blockchain
taking bitcoin as an example, its platform provides the function of transferring money among users, but it does not provide the function of transaction and payment, which makes bitcoin unable to communicate with the outside world, let alone circulate, and thus cannot become a real currency
in order to solve this problem, the exchange was born
role of the exchange:
in addition to the above-mentioned trading and payment, the specific functions of the exchange are roughly asset management, matching trading and asset clearing, etc. To put it bluntly, it is equivalent to the Bank of digital currency. The matchmaking transaction here is actually to exchange for other currencies, such as bitcoin for Leyte. Of course, there are also some basic functions such as recharge and cash withdrawal. In principle, it is a centralized account book without being linked
on the other hand, the exchange also plays the role of stock exchange, making ICO (initial token issue) project possible
all kinds of token (token or token) can be raised and issued through the exchange
at this point, some people certainly think that the exchange is a combination of banking and securities trading
but not only that, the exchange also has the functions of futures and financial management, which means it also has the attributes of financial institutions such as futures exchange, securities companies and fund companies
it is not enough. In fact, the exchange also has the function of supervision, because there is no supervision. Therefore, the digital currency exchange can be regarded as a super financial center
the centralized exchange plays an important role, which obviously brings many security risks and trust crisis
all these are closely related to the violation of the "decentralization" advocated by blockchain
fortunately, some "decentralized" exchanges have emerged, which are based on the blockchain platform and rely on smart contracts to achieve the purpose of automation, de trust and transparency
let's briefly talk about how to build an exchange. Generally, a subject is registered first, such as the Singapore foundation, because the Singapore government encourages the development of blockchain, and high-quality project parties are registered in Singapore, which can be more recognized in the instry
the Singapore foundation can register by providing a company name and identity information of directors, and then it can do some legal compliance, which is also the advantage of the Singapore foundation. It can issue effective legal opinions to make the project compliance.
Binance exchange, with rapid development, has become one of the top five exchanges in the world in just half a year. Unlike idcm.io, which was the first to support vhkd, binance directly issued its own token BNB and launched the exchange
advantages: large trading volume; Support multiple computers and mobile phones; Multi language support; More currencies: 99 cryptocurrencies such as BTC, ETH, LTC and BNB are supported, 235 paired trading markets are available, and the service charge is low; It's faster to recharge and withdraw money
disadvantage: they have no futures and OTC trading, and only support currency trading, and stopped the service to domestic users some time ago, so domestic users need to choose carefully. At the same time, because binance is an exchange trading platform, it cannot be traded directly with legal currency, so it needs to use other platforms to buy cryptocurrency
it's not very convenient to recharge it to coin an network. In addition, in February and March of this year, binance suffered serious security incidents and hackers' leek cutting attacks, and its security performance was questioned
extended information:
the process of digital currency trading through the platform is as follows:
(1) investors should first register accounts, and obtain digital currency accounts and US dollar or other foreign exchange accounts
(2) users can buy and sell digital currency with the money in their cash account, just like buying and selling stocks and futures
(3) the trading platform will sort the buying requests and selling requests according to the rules and start to match them. If they meet the requirements, the transaction will be concluded
(4) e to the difference between the buy and sell volumes submitted by users, a buy or sell request may be partially executed
the mode of digital currency trading through operating companies is as follows: take Ruibo coin as an example, Ruibo coin is operated by professional operating company opencoin, ripple protocol was originally designed based on means of payment, and the design idea is based on acquaintance network and trust chain
to use ripple network for remittance or loan, the premise is that in the network, the payee and the payer must be friends (mutual trust relationship is established), or have common friends (trust chain is formed through the transmission of friends), otherwise the trust chain between the user and other users cannot be established, and the transfer cannot be carried out
1. The central bank's digital currency is definitely just a pure settlement network, which only allows banks and third-party financial institutions to use, and it is likely to stipulate that it must be used among institutions at that time. With this settlement network, the central bank should be able to review every transaction between institutions very easily
2. Don't expect it to be used by ordinary citizens. Freedom, equality and self responsibility are the basic concepts of digital currency. These are not allowed by the central bank
Freedom: the central bank will not allow you to transfer money as you want. The withdrawal of cash abroad should be limited to 100000. How can you complete the transfer by broadcasting data once
Equality: even if you hold on to the private key of reborn, it's hard for reborn to do anything to you. But the central bank needs to have life and death power over your property. So how can the central bank gain the authority to seize you in an open digital currency system? Use an admin level private key? Does it need multi-level permission control? Is it necessary to divide the internal and external network? After all these things are added, isn't that the traditional system? Why add to the cake and add to the blockchain
be responsible for yourself: it's easy to understand. If you lose your private key, it's all over. The reason why Yang Ma is called ma is that this kind of thing must be managed. Private key is too dangerous to be used by ordinary people
therefore, I think too much about what digital currency can fry or even replace bitcoin. It's something that has nothing to do with ordinary people.
This is a Linux system IP address configuration command. The specific meaning is:
set the IP address of the system to 192.168.0.2; The subnet mask is 24, that is 255.255.255.0; The broadcast address is 192.168.0.255; The name of NIC device is eth0
all computers in the network must set a unique IP address to communicate normally. Because of this unique address, users can select the objects they need from thousands of computers efficiently and conveniently when they operate on networked computers
The IP address is just like our home address. If you want to write to a person, you need to know his or her address so that the postman can deliver the letter. A computer sending information is like a postman. It must know the only "home address" to avoid sending the letter to the wrong person. But our address is expressed in words, the address of the computer is expressed in binary numbers eth0 is the name set by the system for the network card. If there are al network cards or multiple network cards, there will be names like eth1 and eth2. The name can be set artificially. It is the unique name of the network card in the current computer system
