Arithmetic power is a measure of the processing power of the Bitcoin network. It is the speed at which a computer can compute the output of a hash function. The Bitcoin network must perform intensive math and cryptography-related operations for security purposes. For example, when the network reaches a hash rate of 10Th/s, it means it can perform 10 trillion calculations per second.

In the process of getting bitcoins through "mining", we need to find its corresponding solution m, and for any 64-bit hash value, to find its solution m, there is no fixed algorithm, but only rely on the computer to randomly collide with the hash, and how many collisions a mining machine can do per second is its "power". This is its "arithmetic" on behalf of the unit written as hash/s, which is the so-called proof-of-work mechanism POW.

Arithmetic for the development of big data to provide a solid foundation for the protection of big data, the explosive growth of big data to the existing arithmetic puts forward a huge challenge. The high-speed accumulation of big data in the Internet era, the total amount of global data geometric growth, the existing computing power can not meet the demand. According to IDC report, 90% of global information data was generated in recent years. And by 2020, about 40% of the information will be stored by cloud computing service providers, and 1/3 of the data will be valuable.

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

Unit of arithmetic power

1 kH / s = 1,000 hashes per second

1 MH / s = 1,000,000 hashes per second.

1 GH / s = 1,000,000,000 hashes per second.

1 TH / s = 1,000,000,000,000 hashes per second.

1 PH / s = 1,000,000,000,000,000 hashes per second.

1 EH / s = 1,000,000,000,000,000,000 hashes per second.
