What does UB mean in bitcoin

3.

Bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan

bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce

bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high

Bitcoin mining is a process that uses computer hardware to calculate the location of bitcoin and obtain it

mining is an incentive process to record data in the bitcoin system. In the bitcoin system, indivial users have the right to pack blocks after calculating a specific hash value by using CPU or GPU to hash

and in order to reward this user for packing blocks, the system will give a certain amount of bitcoin as reward. Because this process is very similar to "mining" in real life, most people call this process mining. In addition to bitcoin, other electronic virtual currencies can also be obtained through mining rewards, such as Ethereum, Monroe and so on

extended data:

mining risk:

1, currency security

the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin

2, system risk

system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income. However, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners

5. Intercommunication, can use these several currencies to purchase the corresponding currency in front!

6. At present, many blockchain websites are using the. Top domain name. You can learn about it

7. Can transfer to Tengxian, very convenient. There are many cars from Yulin to Tengxian.

8. At present, there are two wind tunnels in Sichuan, one in Mianyang Science and Technology Museum and the other in Oct extreme speed space station. Mianyang is researched and invented by personnel of the Chinese Academy of Sciences. It is mainly for military training, but now you can experience it. The ticket price is about 150 yuan. It seems that the bus is No.3 or No.29. I can't remember clearly. OCT's is purchased from a foreign company. Address: No.16, Shaxi line, Jinniu District, Jiaoda interchange, North Third Ring Road, Cheng. 48, 108, 93, etc. In addition, there is a private enterprise in Zhengzhou, Shanghai chuangren Wind Energy Technology Co., Ltd., which has independently developed an entertainment wind tunnel. I feel it's not bad. If you have something unclear, you can ask me again.
