Development of blockchain digital bill system

1. Currency transaction
currency transaction is mainly aimed at the transaction between digital currency and digital currency, in which one currency is used as the pricing unit to purchase other currencies. The currency transaction rule is also to complete the matching transaction according to the price priority and time priority
C2C transaction
both sides of the transaction release the transaction information of buying or selling currency on the C2C transaction platform according to the demand. The buyer and the Seller shall make payment according to the reservation. When the transaction is completed offline, the platform, as an intermediary, charges a certain percentage of the handling fee from each successful transaction
OTC OTC trading
is a set of offline purchase digital currency platform independent of the exchange. Anyone can publish purchase / sale advertisements on the platform. The purchase / sale users can purchase / sell through offline transfer. After the transfer, the platform will transfer the frozen digital currency to the buyer.

2. Decentralized or cold wallets are relatively safe. The private key is backed up by itself and can be checked on all data links. As long as the private key is not leaked, the assets will not be stolen.

3. At present, large enterprises are still facing some of the same international payment problems. The transaction speed is slow, the cost is high, once there is any error, it is difficult to trace the payment. In order to solve this problem, many enterprises will use digital currency to settle accounts, or use digital currency to pay for procts and exchange national currencies through digital currency. Using blockchain technology to make real-time payment for enterprise customers, these payments do not need expensive third-party verification, and the settlement can be completed in a few seconds. At present, few enterprises like Yingtang Zhongchuang apply blockchain technology to the development of digital currency system. Developers and engineers need to design systems that can adapt to changes.

4. Blockchain and digital currency can be said to be closely related, and the application of blockchain technology in the development of digital currency related systems is also certain
even though many enterprises have invested in the research of blockchain, there are few domestic projects of blockchain, so we should make a certain distinction. At present, there are few enterprises applying blockchain technology to develop digital currency system. For example, the digital currency system scheme developed by Yingtang Zhongchuang has many references. There are many systems developed by Yingtang Zhongchuang. You can have a look at them.

5. Tokenpocket wallet can manage a large number of assets on the main chain. The experience is very good and the function is very powerful. What's more, it can also directly open and play DAPP. It should support hundreds of models

6. Aichichain wallet allows indivials or companies to issue their own digital assets. For each asset issued, a certain amount of TCC needs to be handed over to the system. All the paid TCCS will return to the public mine pool and be distributed to each node of the maintenance system through dpos.

7. There must be a concept of MLM. After a visit to a round table, I felt warm and concerned. I applied for a class in Japan and was asked to pay 16500 RMB on the spot. It was in mid October of 17. At the beginning of the 19th century, I suddenly remembered that there was something else. For more than a year, no one told me to attend class. I called my contact person and said that someone contacted me in September of 18, but I didn't get in touch. There is a big difference between the urgency of marketing and the carelessness of payment. They decided to ask for a refund and coordinated for many times. At the end of February, they finally got a refund, only 11550, 70%.

8. If you are a sophomore in high school, you can calculate the problem of analytic geometry
there's no saying that kind of trouble
if you can count all of them, you are definitely well trained in computing.

9. The combination of blockchain and bill can be developed into digital bill. The so-called digital bill is not a new physical bill, nor a pure virtual information flow. It is a brand-new bill presentation form developed by using blockchain technology, combining with the existing bill attributes, regulations and market. Compared with the existing electronic bill, it is completely different in technical architecture. For the specific content of the scheme, I think we can take a look at Yingtang Zhongchuang, which is good at blockchain application development.

10. In fact, blockchain bill is an extended form of electronic digital bill. Before the proposal of blockchain bill solution, the situation of bill fraud and illegal transaction can not be effectively avoided. With the development of blockchain technology, the use of its own characteristics makes digital bill possible and makes up for some defects of bill market.
