China's digital currency characteristics:
China digital currency is the proct of the combination of traditional currency and the Internet, and is the Internet plus of financial and monetary domain. p>
-
China's digital currency will be the only digital currency issued by the state in the world so far, with national credit and currency anchor that bitcoin and other digital currencies do not have
-
China's digital currency can learn from blockchain and other new network technologies to enhance its own security and stability. Blockchain is also a kind of mesh topology, which can rece the task of the central server and has anti-counterfeiting function
-
China's digital currency relies on a secure and stable Internet. The promotion and application of quantum communication technology is of great significance to the security of China's digital currency
< / OL > -
China's digital currency is based on the real RMB, not a kind of currency made out of thin air. The two are only different in form, the former is electronic data, the latter is RMB paper money
-
China's digital currency is a kind of electronic currency created by digital network technology, which also has the main characteristics of network packets
-
digital currency is an encrypted algorithm, just like a cash note with a unique number, which can not be tampered with< br />
what is China's digital currency:
players can only enter the mine cave for mining at a specific time every day. The mine will open from 00:00 to 23:30 every day, and you can't enter the mine for the remaining half an hour. Then you can enter the mine at the foreman after the mine is opened. What players can dig in the mine is mainly black iron ore, which is an important material to strengthen our equipment
the ore cave is divided into three layers. The deeper the position is, the higher the output rate of black iron ore will be. Of course, there will be a greater chance to trigger the boss of the mine. After killing the boss, we can get a lot of rewards. In addition to the black body ore, a lot of slag may be excavated in the mine cavern. These slag can also be exchanged for black iron ore at the foreman. Ten slag can be exchanged for one black iron ore with purity of 1
Mining
when players enter the mine, they can find a corner to mine automatically. In addition to the ore, there will be all kinds of demons in the mine cave. Although the demons in the mine cave are not very strong, our main purpose is to get more black iron ore. of course, we have to avoid the area of these demons to mine
it's better to dig against the wall when mining in the mine cave, or if you choose gold or silver ore, you will have a greater chance to dig black iron ore. Even if the players can't use it for the time being, they can also put the black iron ore on the exchange for sale and get a certain amount of Yuanbao
does mining need tools?
in legend, players all know that mining needs to buy pickaxes. Do you also need it in the hot blood legend mobile version? This is not necessary. Players only need to enter the mine map and click the place they want to mine, and they will mine automatically.
The decline of ATMs is first affected by related manufacturing service providers . Many ATM manufacturers have graally felt the pressure brought by the market, with poor performance and urgent transformation
In the first half of this year, the performance of several listed ATM companies in A-share market is still declining. The data shows that the gross profit rate of ATM and other financial machines is declining. The gross profit rate of some enterprises selling to bank teller machines is only about 2%, with a year-on-year decline of more than 20%in this regard, most ATM manufacturers said in the announcement that the company has been actively transforming. Providing digital currency application technology solutions, ATM operation services and intelligent transportation have become the main transformation direction

extended information:
related instry personnel interview:
1. Zhou Yonghua, general manager of Shenzhen Davao Electronics Co., Ltd.: the most shipment was in 2013. Because of the emergence of mobile payment, the market demand for ATM machines is quite small from 2014 to now. I have the impression that there may be only two or three customers left behind, In the past, there were about 200 orders a month, but now it is estimated that there are only dozens
in order to get more orders, Zhou Yonghua increased the frequency of communication with customers. Through the directors of these ATM manufacturing enterprises, he learned that the ATM market is indeed shrinking and that it is becoming more and more difficult for him to only work as an ATM
2. Employees of XINDATONG Technology Co., Ltd.: the impact on our main business mainly occurred in 2017, 2018 and 2019, now the business scale of our main business is not as upward development as before , which belongs to force majeure. It is not only difficult for one company, but also a global problem, it is not only Chinese enterprises

card number acquisition method based on the magnetic signal of ATM card reader
generally, there are three magnetic heads on the ATM card reader, which respectively read the first, second and third magnetic tracks of the magnetic stripe, of which the first and second magnetic heads are read-only, and the third magnetic head is read-write. According to the international standard of magnetic stripe (ISO / IBM), the card number information is stored in the second track. The magnetic signal is obtained through the second track, and the card number information is obtained through amplification and decoding. The advantage of this method is safe and reliable, but the disadvantage is that the installation requirements are very professional. At the same time, different decoding moles need to be customized for different ATM models<
2,
card number capture method based on the output signal of card reading mole
ATM consists of many moles, such as card reading mole, display mole, printing mole, cash out mole and so on. One of the functions of card reading mole is to determine whether the bank card is valid, and send the card number and other information to the host (ATMC end) to wait for the next processing. Considering the universality and standardization of the mole, the output signal of the card reading mole adopts the general serial communication mode such as 485 or 422 or 232. This method is to send the card number to the host (ATMC) through the card reading mole and send a signal to the ATM monitoring host at the same time. Because this method does not involve other data transactions with ATM host (ATMC end), it is feasible from the perspective of security. At the same time, e to the use of general communication mode, the reliability and operability are also strong<
3.
card number acquisition method based on printing mole
ATM printers are generally divided into receipt printer and flow printer (Accounting printer). Because the communication between printer and host uses common serial port (such as 485, 422, 232), and the flow printer has relatively rich information (such as card number, amount, transaction type, etc.), So this is also a way to get the card number. The advantage of this method is to use the general communication mode, the disadvantage is that the data of the accounting printer is very important, and the intervention of the card number acquisition mole may change the data as the original voucher. At the same time, because ATMC terminal software is generally developed by ATM maintenance manufacturers, the format of the accounting printer is diverse, and the security and ease of operation are not very good<
4,
ATMC terminal active sending mode
because ATMC terminal host actively sends card number, no matter which mode (serial port or network, etc.) requires ATM manufacturer or maintenance manufacturer to modify ATMC terminal software and open relevant interface. There is little operability in the equipment strictly regulated by banks<
5,
network interception mode (commonly known as OTP mode or hacker mode)
at present, ATMC end (common ATM machine) and ATMP end (bank data center) need to communicate normally through network cable in the normal working process of ATM. ATMC terminal needs to send the customer's line code, card number, user's password and other information to ATMP terminal through private network after encryption. After ATMP terminal authentication, the user can carry out normal query or withdrawal operation. This method is to intercept the card number when the ATMC side uploads the card number and other information to ATMP side. The advantage of this method is to use the general TCP / IP protocol, but the disadvantage is that this method can not only obtain the customer's card number, but also obtain the user's password and other information, so the security is very low< To sum up, considering the principles of safety, reliability and easy operation, there are no more than one, two and three methods listed above for getting card number from ATM machine, among which the more common method is the second one, that is, the card number capture method based on the output signal of card reading mole
USB based card reader is a new interface proct launched by ATM manufacturers in line with the development trend of technology, Technically speaking, it is difficult, but at present, some domestic manufacturers have developed corresponding procts, and the application effect is very good.
