Transaction development of digital currency system

1. The point-to-point transaction mode of digital assets is a safe mode for people who want to develop exchanges. Peer-to-peer, indivial to indivial transactions, there is no illegal fund-raising, which avoids disrupting the market. Due to indivial to indivial transactions, many platforms like bitcoin want to transform!

2. First of all, we should make clear the function of the website, and then carry out the development work according to the function (demand). For example, digital currency transaction, first of all, you need to be clear about the currency transaction of your own website, or the third-party digital currency transaction? Secondly, how to verify whether it is a legal digital currency in currency transaction; The rest is the membership mole, and the payment mole. In fact, the most important thing for a website construction is that the website idea should be clear, and then it can be realized one by one.

3. 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.

4. If you don't use the company's quotation, it may be different. I suggest you ask the customer service staff of chainup to get the accurate quotation information.

5. The development of digital currency system has a great influence on paper money. Can it replace it? It can be used at the same time for a period of time. Paper money has collection value and may not be issued.

6. 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.

7. Section area X length x volume weight, 7.85g per cubic centimeter of reinforcement

8. It's very simple to dig down. Don't stand on the block to be g. Insert more torches in the mine cave to mark the way. Don't offend him if you encounter a poisonous spider's nest. You have to take enough armor and weapons. It's a good habit to take a bucket of water when you go out. When you hear the sound of magma in the Gobi, you must be extra careful, no matter up, down, left or right

in fact, how to mine safely? If you play more, you will naturally understand the experience

The spacing width of dowel bars is 10 mm

one end of the dowel bar is fixed in one side plate, and the other end can slide in the adjacent side plate. Its function is to transfer traffic load between two pavement slabs and prevent platform staggering, increase the stress transfer between adjacent concrete blocks, so as to prevent uneven settlement of concrete pavement caused by large local stress of concrete pavement, and transfer stress to make adjacent concrete blocks bear stress together

In the calculation, it is assumed that other parameters remain unchanged and the size of the foundation is graally enlarged, and the stress of the slab is graally stable with the increase of the size of the foundation until the stress converges

through a lot of trial calculation, the calculation size of the foundation is finally determined as 5.0 M × 7. 0 m × 7. 0 m 75 m in width; The length of slab is generally 4.0 m, 5.0 M and 6.0 M. The length of dowel bar is 450 mm, which is set along the joint center line of concrete slab, and the joint width is 10 mm

< H2 > extended data:

contact stress between dowel bar and concrete

the diameter of dowel bar is 32 mm and the length of embedded concrete is 22 cm. The distribution of various contact stresses at the interface between dowel bar and concrete along the length direction of dowel bar is shown in Figure 6. In Figure 6, the horizontal axis is the distance from the center of the seam gap (or the midpoint of the dowel bar). For example, "0" represents the position of the seam, "5" represents the position of the dowel bar 5 cm in the loaded plate, and "5" represents the position of the dowel bar 5 cm in the unloaded plate

the stress distribution along the length direction of the dowel bar is as follows: the maximum contact stress between the dowel bar and concrete is at the joint. With the increase of the distance from the concrete joint, the stress value decreases rapidly, and it is close to 0 at both ends of the dowel bar. In the range of about 8 cm from the joint, all kinds of contact stress values are relatively large. The warping or arching of concrete slab under the action of temperature gradient will lead to the bending of dowel bar
