BTC cat dish
mining is the only way to obtain undeveloped bitcoin, which needs to purchase professional mining equipment for mining, which is called mining machine in the instry
bitcoin miner obtains bitcoin through a lot of calculation through hash algorithm. As we all know, the number of bitcoin is constant, 21 million. As time goes on, the number of miners increases and the number of miners decreases.
the difficulty of bitcoin system is dynamically adjusted. Every 2016 bitcoin is g, an adjustment will be made, The adjustment is based on the block time of the previous 2016 blocks. If the average block time of the previous cycle is less than 10 minutes, it will increase the difficulty. If it is more than 10 minutes, it will rece the difficulty. The purpose is to ensure that the system can output a block every 10 minutes, so the difficulty adjustment time is about 2 weeks (2016 * 10 minutes), that is to say, the output will be halved every four years, And the difficulty will be adjusted every 14 days, so the general trend seems that the output of mining will be less and less
2. Purchasing power for bitcoin
after the prevalence of mining, there are some bitcoin mines, that is, multiple mining machines are concentrated in one place for mining, unified maintenance and management, low electricity price, to rece the cost of mining
the most important parameter of bitcoin mining machine is computing power. The higher the computing power is, the higher the output will be. In the difficulty of bitcoin mining, how much bitcoin can be g with 1t computing power is also used to measure the current difficulty of mining. Therefore, some mines will directly sell computing power to users to dig coins. In this way, the mining risk is relatively lower, and there is no need to buy mining machines and equipment, and no need to maintain them, The maintenance and management of mining machine is relatively troublesome for Xiao
3. Reward for bitcoin
with the rising price of bitcoin, bitcoin has gained more popularity than before, and its position in virtual currency is also unmatched by other currencies. There are some real procts of reward bitcoin mechanism in the market, and cat disk is one of them< The simplest way to get bitcoin is to find the person who holds bitcoin to buy bitcoin, which is equivalent to buying goods. But bitcoin is not required by everyone. Therefore, it is necessary to find the person who holds bitcoin and carry out direct transfer transaction. At the same time, there are certain risks, The other side needs indivials to grasp whether they are cheaters or not, so I don't recommend such transactions on the basis of not being acquaintances or not having certain trust
2. Online trading
there are many trading platforms for bitcoin, large or small. At present, the relatively large and well-known trading platforms are Huo coin, coin security, okex, uto market,... And so on. These platforms are more convenient and safe as three-party guarantee transactions, and the only risk is platform running, But the possibility is relatively small, but some small platforms are not without security
share authorization certification mechanism, dpos for short, is similar to the voting of the board of directors. The coin holders cast a certain number of nodes to verify and account on their behalf. In order to encourage more people to participate in the election, the system will generate a small amount of tokens as a reward. Bitstocks, diandianbi and other digital assets use this method
dpos is a bit like the parliamentary system or the people's Congress system. If representatives can't perform their ties, for example, when it's their turn to keep accounts, they will be removed and the network will select new nodes to replace them
each client of dpos has the ability to decide which nodes can be trusted. Compared with pow (workload proof mechanism), dpos greatly improves the ability of blockchain to process data, and can even achieve second arrival. At the same time, it also greatly reces the cost of maintaining blockchain network security, so that the transaction speed of digital assets is close to that of centralized settlement systems such as visa.
The Chinese version of mist survival patch is a Chinese version of mist survival, a popular sandbox game. It can change the language support of the game after use. The background of the game is set in a world infected by virus. Players will encounter all kinds of mutated creatures and experience a gruesome survival adventure. But because the game is made by foreign manufacturers without Chinese language support, most players will feel confused about the information prompt in the game, and even give up the game. But now you don't have to worry about it. This patch will clear the way for you to add Chinese support for your game text, language, prompt information, etc. the way to use it is also very simple. You only need to it to the game installation directory and run it, and then it can be automatically translated into Chinese

Covalent bonds are formed by sharing electron pairs
van der Waals force includes dispersion force, orientation force and inction force, which are related to molecular dipole
The van der Waals force between the particles should be the dispersive force The orientation force is the positive and negative attraction between the fixed dipoles of two polar molecules, and the inced force is the force proced by the fixed dipoles of a polar molecule incing a non-polar molecule to proce an instantaneous dipole The dispersion force is realized by the attraction of two instantaneous dipoles generated by the motion of the electrons between two nonpolar molecules. In molecular compounds, most intermolecular forces are realized by dispersive forces 
extended data:
when polar molecules and nonpolar molecules are close to each other, under the influence of permanent dipole of polar molecules, the positive and negative charge centers of nonpolar molecules coincide with each other to proce inced dipole, resulting in electrostatic force between permanent dipole of polar molecules and inced dipole of nonpolar molecules, This force is called the incing force. When polar molecules are close to each other, under the influence of permanent dipoles, the distance between positive and negative charge centers of each polar molecule is enlarged, which will also proce inced dipoles, so the inced force also exists between polar molecules
