Mining is a process of increasing the digital money supply. Mining also protects the security of the digital currency system, prevents fraudulent transactions, and avoids "double payments.". By providing computing power for the digital currency network, the miners exchange for the opportunity to obtain corresponding digital currency rewards. It is easy to understand that the process of mining is actually the process of issuing currency by the bank. In addition to issuing currency, the miner also undertakes the work of packing transaction bookkeeping.

就像比特币的世界里，在没有中心化机构刊行的环境下，中本聪设计了一套将比特币的分发设计成给比特币矿工的记账嘉奖：每一次记账权都由所有的矿工通过竞争挖矿发生，，谁先找到正解，谁就可以或许获得嘉奖。而这个寻找正解的进程，我们称之为“挖矿”；参加“挖矿”的人，称为“矿工”。

区块链降生之后“矿工”便有了全新的寄义。譬喻，在比特7kLian.com中的“矿工”是指的是参加维护比特币网络得到比特币收益的小我私家或组织。和传统的矿工差异的是，区块链规模的矿东西有更多的科技色彩，以及更轻松的事情情况。

矿工们验证每笔新的生意业务，而且将生意业务记录在总账本内。约每10分钟就会有一个新的区块被“挖掘”出来，将包括在区块内的每笔生意业务添加到总账本上的生意业务是“确认生意业务”，生意业务被确认后，新的拥有者才气利用他在生意业务中获得的比特币。

挖矿是增加数字钱币供给的一个进程。挖矿同时还掩护着数字钱币系统的安详，防备欺诈生意业务，制止“双重付出”。矿工们通过为数字钱币网络提供算力来调换得到对应数字钱币嘉奖的时机。简朴领略，挖矿的进程实际上是银行发币的进程，矿工除了发币之外，还包袱了打包生意业务记账的事情。

矿工在挖矿中会获得两种嘉奖：建设新的区块嘉奖和区块中生意业务的手续费。为了获得这些嘉奖，矿工们计较基于哈希加密算法的数学题，数学题的谜底被包括在新区块里，作为矿工的事情证明，被称为“事情量证明”，俗称Pow挖矿。

There are two rewards for miners in Mining: a reward for creating a new block and a fee for trading in the block. In order to get these rewards, the miners calculate the mathematical problems based on the hash encryption algorithm. The answers to the mathematical problems are included in the new block, which is known as the "proof of work" as the work proof of the miners, commonly known as POW consensus mechanism.

The essential principle of mining is to run the mining program on the miner and calculate the algorithm to get the reward. The output of a single miner is not stable. In order to obtain a stable income from mining output, a mine pool appears. The ore pool is a collection of miners' mining machines. The more mining machines, the stronger the calculation power. In the total power of the whole network, it accounts for a certain proportion, so as to ensure a stable mining output. When allocating the mining output, it will be distributed in proportion according to the computing power contributed to the ore pool by a single miner, usually the ore pool will charge a small fee.
