If the mining machine has no arithmetic or arithmetic plummeted, it is recommended to check the mining machine first, if it is the network speed or hardware can be repaired, it can be sent with the seller to repair, in order to speed as soon as possible speed of the miner back to work. If the physical damage is irresistible, then the miners can only bear to deal with the pain to reduce the loss, and then buy the corresponding mining machine.

Arithmetic power is a unit of measurement of the processing power of the netcoin network. That is, it is the speed at which a computer calculates 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.

The security threat is by far the most important issue facing blockchain. One of the main issues that blockchains based on PoW *** knowledge processes face is the 51% attack problem, whereby nodes have the ability to successfully tamper with and forge blockchain data by holding more than 51% of the network-wide arithmetic power.

Arithmetic power is a measure of the total computing power of the units that generate new blocks for a given amount of network consumption. The individual blockchain for each coin varies with the time it takes to generate a new block for a transaction.

Arithmetic power provides a solid basic guarantee for the development of big data, and the explosive growth of big data poses a huge challenge to the existing arithmetic power. The high-speed accumulation of big data in the Internet era and the geometric growth of the total amount of global data, the existing computing power can no longer meet the demand.
