首先让我们了解一下区块链的知识，作为比特币的核心原理，每一区块都对应着一份账单，把全部的区块链接起来，就形成了区块链，当你发生的一切交易以及转账，都会完完整整的记录在区块链里面。值得一提的是，这个区块链是存在于网络中的，因此安全性可以得到很好的保证。
Let us begin by learning about the block chain, which, as the central principle of Bitcoin, is that each block corresponds to a bill, links all the blocks, forming the block chain, and that when you make all transactions and transfers, you have a complete record in the block chain. It is worth mentioning that the block chain is in the network, so security is well guaranteed.
每隔一个时间点，比特币系统会在系统节点上生成一个随机代码，互联网中的所有计算机都可以去寻找此代码，谁找到此代码，就会产生一个区块，随即得到一个比特币，这个过程就是人们常说的挖矿。计算这个随机代码需要大量的GPU运算，于是矿工们采购海量显卡用以更快速的获得比特币获利，这也是近期显卡缺货的重要原因。
Every other point of time, the Bitcoin system generates a random code on the system node, which all computers on the Internet can search for, and who finds the code creates a block and then gets a bitcoin, which is what people often call mining. Computing the random code requires a large amount of GPU calculations, and is therefore a major reason why miners buy big cards to profit more quickly on bitcoin, which is a major reason for the recent card shortage.
那这样比特币不就会越来越多，最后完全没有价值了吗?中本聪当然也想到这个问题，这里比特币系统还有一个机制：那就是比特币具有总量有限，前4年总额将产生10500000BTC，每隔4年产出数额减半，在第4年至第8年会产生5250000BTC，第8至12年则只有2625000BTC，如此类推。到最后，总共产生的比特币数量为接近21000000BTC。目前一个1个比特币基于目前的数据结构被分割到8个小数位，也就是0.00000001BTC，矿工们挖到比特币最小的单位就是0.00000001BTC。
So the bitcoin wouldn't be more and more, and it's not worth anything at all. The question certainly came to mind. Here's another mechanism for the bitcoin system: Bitcoin is limited in volume, with a total of 105 million BTC in the first four years, half the output every four years, 5250,000 BTC in the fourth to eighth years, and only 2625,000 BTC in the eighth to twelfth years, and so on. In the end, the total number of bitcoins produced is close to 21 million BTC. One bitcoin is currently divided into eight decimal places based on the current data structure, that is, 0.000001 BTC, and the miners dig the smallest bitcoin unit is 0.000001 BTC.
通俗点说，比特币好比是一座由总量为2100万个金币组成的金山，想要得到它，就需要玩家们利用电脑的运算能力，根据现有的算法计算出一组符合特定规律的数字。
It is commonplace to say that Bitcoin is a gold mountain of 21 million gold coins, and to get it, the players need to calculate a certain set of numbers based on existing algorithms, using computer computing capabilities.
想必大家也明白了算力越强，挖出比特币的概率越大，现在中国的算力已经达到了全世界的75%，换句话说，全世界的比特币中有75% 是来自我们国家的，那具体要花费多久的时间才能挖到一个比特币呢?
I'm sure you also understand that the better the math, the more likely the bitcoin is to be found, now that China has reached 75 per cent of the world, in other words, 75 per cent of the world's bitcoins are from our country, and how long will it take to find a bitcoin?
由于之前的比特币十分的好挖，导致了很多人加入了挖矿的行列，但是随着人数的越来越多，挖矿的难度也变得越来越大，如今想要一个人挖矿，普通电脑已经无法承担了。根据业内人士表示，在2014年的时候，平均每挖出100个比特币所产生的电费高达50万，对你没有看错，就是50万，相当于每枚耗电达到了5000元，而现在已经翻倍。
Since the previous bitcoin was very well dug, many people have joined in mining, but with increasing numbers, mining is becoming more difficult and ordinary computers can no longer afford to dig alone. According to industry, in 2014, an average of 100 bitcoins was dug up at a cost of half a million dollars, and you are right, half a million dollars, equivalent to 5,000 dollars per piece of electricity, which has now doubled.
在2014年，每天的总计算力达到了4000Ghash/s，而挖矿的计算能力则为100Mhash/s，做个简单的除法预算就能得知，每24小时能够挖出3600个比特币。如果你不太好理解我们可以换个说法，相当于1亿个骰子扔出小于1亿零50的数字，谁先扔出来，谁就获得记账权。此时，1亿零50就是个哈希值，扔骰子的过程叫做哈希碰撞，而挖矿算力的单位就是每秒钟多少次哈希碰撞。
In 2014, the total daily calculus was 4,000 GHash/s, while the mine-mining capacity was 100 MHash/s, and a simple cut-off budget could tell that 3600 bitcoins could be dug up every 24 hours. If you don’t understand the alternative, it would amount to 100 million dice throwing numbers less than 150 million, and anyone who throws them first gets the right to bookkeeping. At this point, 150 million is the Hashi value, the dice-throwing process is called Hashi colliding, and the unit of mine-drawling power is the number of Hashi collisions per second.
比特币全网算力达到236万万亿次哈希碰撞每秒，相当于20多万个50米长的标准游泳池里面水滴的数目。但即便是这么大的算力，也需要10分钟左右才能碰撞到一个符合要求的哈希值。
Bitcoin’s full net capacity reached 236 trillion Hash collisions per second, which is equivalent to the number of droplets in more than 200,000 50-metre-long standard swimming pools. But even this size takes about 10 minutes to collide to a desired Hash value.
由于比特币的总量是固定的，到如今已经挖出了80%的比特币，大约在1680万枚左右，虽然只剩下了五分之一左右，但是其价值以后还会不断的攀升，这也会导致有更多的人花费更多的时间和精力加入到挖矿大军中。
Since the amount of bitcoins is fixed, 80 per cent of the bitcoins have been excavated to date, approximately 16.8 million, and although only about a fifth of them remain, their value will continue to rise, which will also result in more people spending more time and effort on joining the mining army.
2010 年之前还可以用个人电脑挖挖比特币，但现在完全不可能了。其实，中本聪在设计比特币时，为区块设定了1M的容量上限，这样可以在个人电脑上就得以顺利运行整个区块链，但随着区块扩容至8M(大大增加难度系数)，普通家用电脑被强制淘汰，算力的把控权中心化转移到了矿场主手中。
It is also possible to dig bitcoin with a personal computer before 2010. In fact, China has set a 1M capacity limit for blocks when designing bitcoin, so that the entire block chain can be successfully run on PCs, but with the expansion of blocks to 8M (a significant increase in the difficulty factor), ordinary PCs are forcibly phased out, and arithmetic centralization of control is transferred to mine owners.
如今挖矿都是相当耗钱的事，因为要配置专门的矿机才行，每台机器挂着6~8块显卡，以一台比较新的计算能力是13个T的矿机来计算，一天24小时运行，能挖出0.004549382个比特币。而且这样的矿机，只要数十台，每月的耗电量就会高达1万度。还有个人自己买了两台矿机，结果呢?
Mining is expensive today, because it needs to be equipped with a dedicated mine machine, with six to eight cards attached to each machine, which, based on a relatively new machine with 13 Ts, operates 24 hours a day, and can dig 0.004549382 bitcoins. And if there are dozens of such machines, the amount of electricity will be 10,000 degrees a month. And what happens when a man buys two miners himself?
他所使用的矿机功率为1350瓦，按照每天运行24个小时，可以挖出0.0018个比特币计算，成功挖出一枚比特币的时间约为556天。按照功率1000瓦每小时约用1度电，矿机每天的耗电量为32.4度。每天耗电费用约为16.8元，成功挖到一枚比特币的成本约9367元。
He used a mining machine of 1350 W, which, based on 24 hours of operation per day, was able to excavate 0.0018 bitcoins, which was successfully excavated for about 556 days. At a power rate of 1,000 watts, he used about 1 degree per hour, and the miner consumed 32.4 degrees per day. The daily cost of electricity consumption was approximately $16.8, and the cost of successfully digging into a bitcoin was about $9367.
