Payment is not only a very mature technology, but also a mature industry. However, it is very tedious for businesses to access the payment system. Usually, you have to register a developer account in the payment service provider's platform and purchase the interface service before you can use the payment interface. The debugging and use of the payment interface is a large cost. In particular, many payment interfaces do not provide real-time settlement, payment service providers for their own interests, the settlement cycle is basically calculated on a monthly basis. For merchants, although you can see every order paid by the user, it will take a month to get the money. Merchants get numbers, while payment service providers get cash flow. There are many small shops, and a month's cash flow can drag down hope for the future.

This is not fair. Why did the merchant's money flow into the pocket of the payment service company?

Blockchain is a revolution in production relations. Where there is a middleman to earn the price difference, there is the use of blockchain force. Blockchain payment can remove the intermediate link. This intermediate link is the payment service provider.

In the world of blockchain, no one can deduct the price difference. In blockchain payment, the customer settles accounts with the merchant directly. The merchant's money arrives in the account immediately.

This is the meaning of blockchain payment. Make the payment fairer and get rid of the middleman to earn the difference.

But many people say that blockchain is not suitable for payment, especially real-time payment. In the environment where tps basically depends on blowing, there are very few that can support real-time payment in new offline retail scenarios. Even if real-time payment can be achieved, it is often questioned. The common question is why blockchain should be used to make payments. Isn't centralized payment much more efficient than blockchain?

When it comes to efficiency, blockchain is actually more efficient than traditional payments. Especially cross-border payment and cross-bank payment. Compare the slowest bitcoin to the banking system. The transfer speed of the special currency is very slow, and it takes an hour to finalize a transaction. But this is also much faster than the cross-border payment speed of banks, and even twice the speed of domestic inter-bank transfer within 2 hours.

But Bitcoin is not suitable for real-time payment, such as buying ice cream on the street or riding a shared bike. But if you buy a house, shop online, or play placement games, even if you can confirm it an hour later, it will have no impact on the user experience.

In addition, Bitcoin is not the only payment for blockchain, but many blockchain projects are so fast that they can be paid in almost a second, so it's no problem to make small real-time payments.

There is also a serious problem in traditional payment. Many users have encountered the bad experience of being swiped by the shop assistant several times and deducted by the shop assistant because of the bad signal. At this time, the shop assistant sometimes does not admit to deducting too much money, and the system cannot find it. Or the record is deleted by the business, and the rights and interests of users are easily trampled on.

And blockchain payment, every transaction, can not be tampered with. If the transaction is not successful, it will not be deducted, and the history of the transaction cannot be tampered with. If there is a behavior of deducting money, it is clear at a glance that anyone can view it in the blockchain browser. This is the advantage of blockchain payment.

Said a lot of advantages, in fact, blockchain payment also has disadvantages. The biggest problem is that almost every blockchain project has a currency price, which is unstable due to the existence of transactions. This is the biggest problem for payment. Imagine a man who sells pancakes. He has to decide the amount of money he charges every minute according to the trend of the currency price, and the customer spends differently at different times, which is a very bad experience.

Therefore, for block chain payment, the focus is to solve the problem of currency price fluctuation, while non-coin block chain is a good way to try.
