2008年全球金融危机，比特币创始人中本聪的第一篇论文诞生。
The 2008 global financial crisis saw the birth of Bennett's first paper among the founders of Bitcoin.
2009年比特币诞生。
Bitcoin was born in 2009.
这绝不是偶然。
This is no accident.
比特币诞生有两个特点，一是不可增发，从诞生第一天起总量就锁定了，2100万枚，这就是针对政府的货币滥发。二是不受任何中心化机构监管，包括央行和金融机构。
Bitcoin was born with two characteristics: it was immeasurable, with a total of 21 million from the very first day of its existence, i.e., currency abuses against the government. Second, it was not regulated by any centralized institutions, including central banks and financial institutions.
简单点说，中本聪把比特币设计成一堆复杂算法所生成的特解。特解指的是方程组所能得到的解中的一组，而每一个特解都能解开方程并且都是唯一的。因此，比特币就好比是人民币的序列号，是唯一的，因此具有恒定特质，可以充当货币。
Simply put, China has designed bitcoin into a complex array of algorithms to produce a decomposition. The decomposition refers to a set of solutions that an equation group can obtain, and each one can solve the equation and is the only one. So, Bitcoin is like the serial number of the renminbi, the only one, so it has a constant feature that it can act as a currency.
现在大家所进行的挖矿，实质就是通过庞大的计算量不断的去寻求这个方程组的特解，这个方程组被设计成了只有2100万个特解，所以比特币的上限就是2100万。
Now you've been digging for the essence of this equation, which has been designed to be 21 million, and the upper limit of Bitcoin is 21 million.
前面我们讲过挖矿和算力，“挖矿”是指通过电脑的强大算力不断地去寻求这道超级数学题的一个特解。截止2018年初已经挖出来大概1400万个比特币，相当于这道超级数学题已经被找到了1400万个特解，也就是说比特币还有700多万个是没有挖出来的。随着时间的推移，它的产生将会越来越慢。解锁将会越来越复杂，获得的比特币却会越来越少。
As we have said before, mining and arithmetic, the term “mining” refers to the constant search for a special description of a supermathematical subject through the powerful computing power of computers. By the beginning of 2018, about 14 million bitcoins had been discovered, equivalent to 14 million bitcoins, which meant that more than 7 million bitcoins had not been excavated.
我们来看一下比特币产生的时间表：
Let's take a look at the timetable created by bitcoin:
格林尼治时间2009年1月3日18点15分05秒，中本聪挖出了比特币网络的第一个区块，也就是编号为0的创世区块。
On 3 January 2009, at 18.15 minutes and 05 seconds Greenwich Time, China was able to dig up the first block of the Bitcoin network, the original block number zero.
从创世区块到第20999个区块为阶段1，在这个阶段里矿工每完成一个区块的记账，可以得到50个比特币的奖励，也就是比特币网络中每生成一个新区快，比特币的数量就增加50。
From the Genesis block to block 20999, phase 1, during which the miners will be awarded 50 bitcoins for each block they have completed, i.e., 50 more bitcoins for every new zone that emerges quickly in the Bitcoin network.
出于某些原因，中本聪认为比特币产生的速度应该递减。于是从第21000个区块(该区块产生于2012年)开始，称为阶段2，每生成一个新区块只增加25个比特币。
For some reasons, China believes that Bitcoin should be produced at a reduced rate. So starting with the 21,000 blocks (which originated in 2012), known as phase 2, there is only 25 bitcoins per new block generated.
这样继续下去，每生成21000个区块，比特币就进入下一个阶段，每个新区块带来的新比特币数量减半。直到第33次减半时，每个块产生的新比特币从0.0021个直接减为0个。
As this continues, for every 21,000 blocks generated, Bitcoin moves to the next stage, where the number of new bitcoins per new block is halved. Until the 33rd time, the number of new bitcoins generated by each block is reduced from 0 to 0.0021.
这样算一下，总共产生的比特币就是20999999.97690000个。
In this way, the amount of bitcoins generated is 209999999.9769000.
