Development of digital currency exchange
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.
