矿池的幸运值指的是什么？有什么影响？
What's the lucky value of the pond? What's the effect?
我们在查看矿池算力排行榜时，会发现很多网站还会给出“幸运值”数据。什么是幸运值呢？它会带来哪些影响呢？今天，我们就来了解一下
When we look at the pond's arithmetic rankings, we find that there are a lot of sites that give the "lucky" data. What's the lucky value? What's the impact? Today, let's get to the bottom of this.
01
什么是幸运值
比特币挖矿，就是矿机不断寻找随机数进行哈希运算的过程。如果哈希运算的结果符合比特币的系统要求，那么就赢得了这一次的记账权和对应的区块奖励。所以，谁的算力多，运算的速度快，谁得到区块奖励的概率就越高。
Bitcoin digs, which is the process by which the miner keeps searching for random numbers for Hashi calculations. If the results of the Hashi calculations meet the system requirements of Bitcoin, it will win this time the right to bookkeeping and the corresponding block reward. So, the more likely it will be that someone will get a block reward if they have more and faster calculations.
长期来看，挖出区块的概率和自身拥有的算力占比成正比，但短期内会产生波动。这就好比抛硬币，每次正面朝上的概率都是50%，但你可能连续抛10次每次都是正面朝上，正面朝上的出现频率变成了100%，这是因为10次作为样本还是太小。抛的次数越多，出现正面朝上的频率越接近于其概率，即50%。
In the long run, the probability of digging blocks is a positive ratio to the arithmetic power of the blocks themselves, but fluctuations occur in the short term. is like a coin toss, 50% for each front, but you may throw 10 times in a row, each front to the head, and the frequency of the front to the head becomes 100%, because 10 times as a sample are too small. The more times you throw, the closer the positive up frequency is to the probability, that is, 50%.
比特币挖矿也一样。如果A矿池的算力是10E，全网算力是100E，那么理论上A矿池爆块的概率是10%，也就是说100个区块中，被A矿池挖出的区块有10个。但在实际过程中，A矿池可能运气爆棚，挖出了20个区块，也可能倒霉到只挖出了1个区块。实际爆块数量和理论爆块数量的比值，我们称之为“幸运值”。
The same is true of bitcoin mining. If the size of a pond is 10E, and the full net is 100E, the theoretical probability of a pond bursting is 10%, that is to say, 10 out of 100 blocks. In practice, however, a pool is likely to be lucky enough to dig up 20 blocks, or it may be bad enough to dig up only one block. The actual number of blasts versus the theoretical number of blasts is what we call the “lucky value”.
在上面的例子中，如果A矿池挖出了20个区块，那么幸运值就是200%；如果只有1个区块，幸运值就是10%。正常情况下，矿池的幸运值为100%。
In the above example, if a pond digs up 20 blocks, the lucky value is 200%; if there's only one block, the lucky value is 10%. Normally, the lucky value is 100%.

幸运值的影响
“要建比特币矿池，先要有1000个比特币。”
"[b] To build a pit of bitcoin, there must be 1,000 bitcoins first. "
这不是耸人听闻。正如大额的比特币转账需要6个区块确认才保险，建设矿池也需要1000个比特币抵御幸运值波动的风险，因为现在很多矿池都是按照理论收益给矿工们结算的（PPS收益模式）。
This is not sensational. Just as large bitcoin transfers require six blocks to be recognized for insurance, building a pond also requires 1,000 bitcoins to protect against the risk of lucky fluctuations, because many ponds are now settled for miners on the basis of theoretical returns (PPS returns model).
如果没有1000个比特币作为保险金，又遇上好几天幸运值偏低，矿池就会有倒闭的风险。曾经有一家矿池，因为幸运值偏低，亏了400多个比特币，好在这家矿池家底雄厚，挺过了那段倒霉的日子。
Without 1,000 bitcoins for insurance and a few days of low fortunes, the ponds run the risk of collapse. Once there was a pond that lost more than 400 bitcoins because of its low fortune value.
所以，幸运值的波动，受影响最大的就是矿池。建设矿池的技术门槛在逐渐下降，但资金门槛却在上升（因为比特币长期在涨）。
So, the most affected by the fluctuations in the luck values is the ponds. The technical threshold for the construction of the pits is gradually declining, but the financial threshold is rising (as bitcoin is rising for a long time).
另外，幸运值也会影响选择了PPLNS收益模式的矿工。不同于PPS模式按照理论收益结算，PPLNS是按照实际爆块收益来结算的。如果幸运值偏低，长时间不爆块或者爆块数量寥寥无几，那么接入到这家矿池的矿工们就要承受损失了。当然，如果幸运值偏高，PPLNS的收益也会比PPS的收益高。
Also, lucky values affect miners who choose the PPLNS revenue model. Unlike the PPS model, which settles on theoretical returns, PPLNS settles on actual burst revenues. If lucky values are low, if there are little or no long non-blasts, the miners who access the pond will suffer losses. Of course, if lucky values are high, PPLNS will also earn more than PPS.

小结
幸运值指的是实际爆块数量和理论爆块数量的比值，受幸运值影响最大的是矿池，其次是选择了PPLNS收益模式的矿工。建设矿池前需要有1000个比特币，就是为了抵御幸运值波动带来的风险。
The lucky value refers to the ratio between the actual number of pieces and the theoretical number of fragments, the most affected by the lucky value being the ponds, followed by the miners who have opted for the PPLNS returns model. The need for 1,000 bits of coins before the ponds can be built is to counter the risks posed by the volatility of the lucky values.
