比特币的全网算力是指所有参与挖矿的计算机设备（矿机）的计算能力的总和。它是衡量比特币网络安全性和挖矿难度的关键指标之一。
Bitcoin’s full-network algorithm refers to the sum of all computing devices (mine machines) involved in mining. It is one of the key indicators for measuring the safety of Bitcoin’s network and the difficulty of mining.
以下是计算比特币全网算力的几种方法：
The following are some of the methods used to calculate the full net power of bitcoin:
1. 矿池算力占比法：
这种方法是通过统计各大矿池的算力占比来估算全网算力。首先，获取各大矿池的算力数据，然后将这些数据相加并乘以相应的百分比，以得到全网算力。这种方法的优点是实时性强，可以快速反映当前的网络状况；缺点是不够精确，因为矿池之间的算力可能会重叠。
The method is to estimate the full net capacity by measuring the arithmetic share of the major ponds. First, to capture the arithmetic data of the major ponds, and then to add them to the corresponding percentages in order to get the full net. The advantage of this method is that it is real-time and can quickly reflect the current network situation; and the disadvantage is that it is not accurate, because there is a risk of overlap in the arithmetic between the ponds.
2. 区块难度法：
这种方法是通过分析比特币区块链的难度变化来估算全网算力。首先，获取最近一段时间内的区块难度值，然后根据难度调整公式（即每个区块的生成时间）反推计算出这段时间内的平均算力。最后，将这个平均值作为全网算力的估计值。这种方法的优点是相对准确，因为它考虑了所有矿工的贡献；缺点是时效性较差，需要等待一定数量的区块生成后才能得出结果。
The method is to estimate the full net value by analysing the difficulty changes in the bitcoin block chain. First, to capture the difficulty values of the blocks over the recent period, then to calculate the average value over that period based on the difficulty adjustment formula (i.e., the time of each block generation). Finally, to use this average as an estimate of the full net value. The advantage of this method is to be relatively accurate, as it takes into account the contribution of all miners; and the disadvantage is to have a less time-sensitive result, waiting for a certain number of blocks to be generated.
3. 区块链浏览器法：
这种方法是通过访问比特币区块链浏览器，查看当前的区块高度和平均出块时间，然后利用上述的区块难度法来估算全网算力。这种方法的优点是简单易行，可以在任何时间查看实时的全网算力；缺点是依赖于第三方服务，可能存在数据不准确或延迟的问题。
This is done by accessing the Bitcoin block chain browser, looking at the current block height and average block time, and then using the block difficulty method described above to estimate the full web capacity. The advantage of this method is that it is simple and easy to see the real-time full web capacity at any given time; the disadvantage is to rely on third-party services and there may be problems of data inaccuracy or delay.
比特币的算力单位主要有两种，H/s和KH/s。其中，H/s是最小的单位，表示每秒做一次计算机随机的hash碰撞。而KH/s表示每秒1000次哈希，即1KH/s=1000H/s。此外，在实际中，我们可能还会看到EH/s这样的单位，1 EHash等于10的6次方THash，也就是10^6 THash。
Bitcoins have two main units, H/s and KH/s. Of these, H/s is the smallest unit, which means one random hash collision of a computer per second. KH/s means 1,000 Hashis per second, i.e. 1KH/s=10000H/s. In addition, in practice, we may also see units like EH/s, 1 EHash equals 10 x 6 x THash, i.e. 10~6 THash.
算力（也称哈希率）实质上是比特币网络处理能力的度量单位，具体来说，它表示计算机（CPU）计算哈希函数输出的速度。例如当网络达到10Th/s的哈希率时意味着它可以每秒进行10万亿次计算。因此，全网算力的大小取决于网络中参与挖矿的矿机数量和每台矿机的算力。如果网络中共有1亿台矿机，每台矿机的算力是10T，那么全网算力就是10亿T。
Arithmetic (also known as Hashi rate) is essentially the unit of measure of Bitcoin network processing capacity, specifically, which means that a computer (CPU) calculates the speed of Hashi output. For example, when the network reaches the 10th/s Hashi ratio, it can be calculated 10 trillion times per second. Thus, the size of the whole network depends on the number of miners involved in mining and the capacity of each miner in the network. If there are 100 million miners in the network, the computing power of each miner is 10 T, then the full network capacity is 1 billion T.
EH/s也是比特币算力的一个单位，表示每秒10的18次方次哈希运算，也就是1艾西（Ehash）。具体来说，1艾西等于每秒进行1,000,000,000,000,000次哈希碰撞。在实际中，我们可能还会看到其他不同的算力单位，例如H/s（每秒做一次计算机随机的hash碰撞），KH/s（每秒1000次哈希，即1KH/s=1000H/s）等。这些不同的单位可以帮助我们更准确地衡量和比较不同矿机的算力大小。
EH/s is also a unit of bitcoin power, which means that there are 18 bits of al-Hash, or 1 Ehash, at 10 times per second. Specifically, 1-Ai-Si is equal to 1,000,000,000-100,000 hash collisions per second. In practice, we may also see other different units, such as H/s (a random computer hash collision per second), KH/s (a thousand al-Hah/s=10000H/s). These different units can help us more accurately measure and compare the computing power of different miners.
