The following describes in detail embodiments of the present invention with reference to the accompanying drawings.

The bitcoin is a virtual encrypted digital currency in the form of P2P, the point-to-point transmission means an decentralized payment system, unlike all currencies, the bitcoin is not issued by a specific currency institution, and is generated by a large number of calculations according to a specific algorithm, and the bitcoin economy uses a distributed database consisting of numerous nodes in the whole P2P network to confirm and record all transactions, and uses a cryptographic design to ensure the security of all links of currency circulation. The decentralized nature of P2P and the algorithm itself may ensure that monetary value cannot be manipulated artificially by making large quantities of bitcoins. The cryptology-based design may allow bitcoins to be transferred or paid only by the true owner.

The nature of bitcoin is that it is actually a particular solution generated by a complex set of algorithms, where a particular solution is one of a finite number of solutions available to a system of equations, and each particular solution is unique and capable of solving an equation. Compared with the banknotes, the bitcoin is the crown word number of the banknote, and if you know the crown word number of a certain banknote, you own the banknote. The process of digging the mine is to continuously seek the special solution of the equation set through huge calculation amount, the equation set is designed to be only 2100 ten thousand special solutions, so the upper limit of the bitcoin is 2100 ten thousand.

Computational power (also known as hash rate) is a measure of the processing power of a bitcoin network. I.e. the speed at which the hash function output is calculated for the Computer (CPU). 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 means that it can perform 10 trillion calculations per second.
