mining is perhaps one of the most important components of the bitcoin ecosystem. Miners need to solve complex mathematical problems, so as to ensure the smooth implementation of the transaction. These problems are so complex that they are difficult to solve even for extremely powerful computers. Computers need work and luck to solve these mathematical problems, just as miners dig underground. The chance of solving this problem correctly is about one in 13 trillion

bitcoin mining has two purposes. Firstly, by solving mathematical problems, bitcoin miners can verify the transaction information, so as to ensure the security and reliability of bitcoin payment network. Miners are the people who ensure that transactions are accurate and that there is no "double payment."

Secondly, when the computer solves these complex mathematical problems on the bitcoin network, the system will generate new bitcoin, which is similar to the process of mining gold from the ground. The reward is called "block reward", and after the event called "halving", its amount will be periodically halved. The newly discovered concept of bitcoin is an important part of bitcoin protocol. The bitcoin obtained by the miners is brand new and has never been in circulation before

since miners will eventually sell the bitcoin, it is also an important source of supply and liquidity. As chainalysis reports, many digital currency exchanges rely on miners to receive bitcoin and increase their liquidity. Typically, exchanges get about 88% of bitcoin from other exchanges, and bitcoin miners are the largest source of the remaining percentage. As you can imagine, there is fierce competition between exchanges to receive bitcoin directly from miners

further enlarge the map, most of the mining activities are only carried out in four provinces, the first two provinces are Xinjiang and Sichuan, accounting for nearly half of all bitcoin mining in China. Electricity prices are cheap and the weather is cold in these areas. This helps to keep mining profits and equipment cool ring the 24 / 7 operation and maintenance period of bitcoin mining

but this is nothing new for digital currency issuance. For many years, China has been a major market for bitcoin miners e to its cheap electricity and abundant resources. Bitmain, f2pool and Canaan are all located in China

whether this is a negative or positive message depends on your point of view. But for decentralized, distributed, unlicensed networks, geographic regions across multiple entities are more healthy for the entire ecosystem

2. The assembly of the chain plate conveyor, as described in the description 1, the hollow section part includes a longitudinally extended hollow part, through which the chain link is extended and includes a clearance channel, which extends downward to the hollow section part and opens outwards at the bottom of the hollow section

3. After the goods arrive at the next transfer station, e to some reasons, the information can not be entered into the system or displayed, the goods may be returned, may have been sent to the customer, but it is more likely to be "lost". It's better to ask the express company to track and check through the internal system

4. You can never get to Beijing by subway from Shanghai. The embassies are all in Beijing, the capital. From Shanghai to the capital, trains and planes. Get off at the city library of line 10 of the consulate, take No. 548 at Gao'an Road, Huaihai Road, get off at Jianguo West Road, Gao'an Road, and walk to the consulate.

5. This is a non restrictive attributive clause, which is a supplement to the preceding chain reaction to some extent. It's not a nominal clause. Nominal clauses refer to subject clauses, object clauses and appositive clauses.

6. In the following passage, panda is used to replace light and dark dragon
1
the panda effect is a must effect, and it's useless if we don't talk about the enemy. But there is an adjustment: in the same chain, the panda can not launch the effect twice, for example, if the opponent has a panda on the field,
you have two cards a, you launch one, the panda must send the effect to keep up with chain 2, you chain card a
chain 1 card a (invalid)
chain 2 panda
chain 3 card a (effective)

2. The concept of launching is that the moment when the devil trap comes into play is called launching. That is to say, the perpetual devil trap only needs to be launched once, not every round
therefore, if the hypergravity net was on the field before the panda appeared on the stage, it means that it has been started long ago, there is no need to start it again, and the panda can't use it
however, if the panda appears before it, it will be invalid by the panda
no matter whether it is invalid or not, the permanent magic trap will remain< br />
3 The world is so big that there are all kinds of strange things. Different people have their own ideas. I didn't delve into panda tactics. But I know the attack and defense of panda is not cost. In other words, the panda can have unlimited invalid effects (as long as he doesn't die), even if the attack and defense are 0. Because it is invalid first and then reced.

9. The origin of this symbol is in 1971. Ray Tomlinson, a computer engineer of BBN computer company, worked in the US Department of defense to develop the military network ARPANET. He was ordered to find a representation format of e-mail address. He first wrote a small program, which can combine the file transfer protocol of the program with the sending and receiving ability of another program, So that a letter can be sent from one host to another. So the first email was born. Although it is used by people all over the world every day, there is no official name for "@". Some read "circle a" and others read "att". In Germany, Holland and South Africa, @ is called "monkey's tail", in Russia, @ is called "dog", in Finland, @ is called "Mimi", in France and Italy, @ is called "little snail"?
