1mH computing power

1. Lightcoin is 1.8g. The computing power of the whole network is only 8600gh / s, and 1080ti graphics card occupies 1 / 4700
eth is only 32mh / s, 1070 has 40mh / s. Many people say that 1080ti can't pull up the computing power because of the high delay of gddr5x video memory. As expected, it's better to mine with a card. People on the Internet say that 480 can have 65mh / S computing power
Zec, 724sol / s, nearly three 1060 3G, the total price is more expensive than three 1060 2K soft coins. However, compared with the short supply a-card rx4808g, the price of three cards is less than 5K, and the computing power is 900 + sol / s, but it's useless if there is a price but no market
it's too wasteful to use this card for mining. It's just for fun and can't afford to hurt.

Computing power is a measure of bitcoin network processing power. That is, the speed at which the computer calculates the output of the hash function. Bitcoin networks must perform intensive mathematical and encryption related operations for security purposes. For example, when the network reaches a hash rate of 10th / s, it can perform 10 trillion calculations per second

in the process of getting bitcoin through "mining", we need to find its corresponding solution M. for any 64 bit hash value, there is no fixed algorithm to find its solution M. we can only rely on computer random hash collisions. How many hash collisions can a mining machine do per second is the representative of its "computing power", and the unit is written as hash / s, This is called workload proof mechanism pow

computing power provides a solid foundation for the development of big data, and the explosive growth of big data poses a huge challenge to the existing computing power. With the rapid accumulation of big data in the Internet era and the geometric growth of global data, the existing computing power can no longer meet the demand. According to IDC, 90% of the global information data is generated in recent years. And by 2020, about 40% of the information will be stored by cloud computing service providers, of which 1 / 3 of the data has value

therefore, the development of computing power is imminent, otherwise it will greatly restrict the development and application of artificial intelligence. There is a big gap between China and the advanced level of the world in terms of computing power and algorithm. The core of computing power is the chip. Therefore, it is necessary to increase R & D investment in the field of computing power to narrow or even catch up with the gap with the developed countries in the world

unit of force

1 KH / S = 1000 hashes per second

1 MH / S = 1000000 hashes per second

1 GH / S = 1000000000 hashes per second

1 th / S = 100000000000 hashes per second

1 pH / S = 100000000000 hashes per second

1 eh / S = 100000000000 hashes per second

4. This depends on the power of the Miner you buy. If the power is high, the speed of mining is natural. However, mining can not only depend on the calculation power, but also on the overall performance of the miner. The following is the revenue data of Avalon official Miner:

7. Xiaomi bracelet has many functions, such as exercise step counting, sleep monitoring, caller ID, notification and reminder, and many other functions, such as heart rate monitoring, screen unlocking, secret free payment, etc. the total shipment volume of Xiaomi bracelet has exceeded 4500W, with high cost performance.

8. Aprotic solvent is also called aprotic transfer solvent. The proton self delivery reaction of this kind of solvent is very weak or has no self delivery tendency. According to their interaction with solute, they can be divided into dipolar aprotic solvent and inert solvent. This kind of solvent can be divided into: aprotic nonpolar solvent, such as benzene, ether, carbon tetrachloride, etc; Aprotic polar solvents, such as dimethyl sulfoxide, N, N-dimethylformamide, acetone and so on, because the molecules of aprotic polar solvents have polarity, they will affect solute molecules and proce solvation effect. Protonic solvent contains - Oh, - NH, such as methanol, which will form hydrogen bond with nucleophilic reagent and make nucleophilic reagent solvable. Aprotic solvent, also known as proton inert solvent, can not give protons in the reaction system can be called aprotic solvent. Aprotic polar solvents, such as acetonitrile (CH3CN), dimethylformamide (DMF), dimethyl sulfoxide (DMSO), hexamethylphosphoryltriamide (HMPA), etc. Aprotic polar solvents can solvate cations, especially metal cations. Protonation gives a hydrogen ion, which is positively charged, making it more electrophilic. O. The coordination of H + on N and other elements can be simply understood as combining with proton, that is, combining with a proton. Generally, the substance has lone pair electrons, so it can combine with a proton through coordination bond. For example, when H2O becomes H3O + NH3 becomes NH4 +, different substances have different protonation ability, and some substances with larger dipole moment often have weak protonation ability
