Add safety circle calculation force

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

2. There are a lot of deceptive software for digital currency. Be careful. If you want to make digital currency, there is a great risk. Be careful

3. From your description, your PI coin is added to the security circle, and your iPhone is used to delete spaces. It is recommended that you delete spaces through the delete key of input method.

4. Five have been added to the coin distribution security. Why is it called 60%? Because of this meaning, one takes two generations 60%, because of this word

5. The reason why mobile phones can't add this security circle is that mobile phones are limited and don't support this platform, so there's no way to join.

In order to adapt to all kinds of car use, the center hole of the refitted wheel hub is generally large, while the original car is generally small. For example, Yishen's is 67.1, and the refitted wheel hub is 73.1, so it will be big after being put on, and there will be a gap in the middle, so you need to add a recing ring. This thing is not high technology, and it will not affect the safety, but it will not work if it is not put on, If it is serious, the screw will bear too much load, deform and break, and the consequences are unimaginable.

thirty nine feet wear 40 pairs of shoes, and they need to wear two pairs of socks to fit. The diameter changing ring is the pair of socks that are added, and you can play football without adding them

9. In my opinion, my cousin trained for three months in the security cow class, and then passed the examination of CISM registered information security manager certification, which brought him great advantages in the future work of information security supervisor.
