深入解析比特币挖矿

当我们提到比特币挖矿时，它就像淘金一样，只是这次淘的是虚拟货币。要想成功地挖掘比特币，我们需要准备一些必要的步骤和工具。接下来让我们一起探讨这个过程。

When we talk about bitcoin mining, it's like gold mining, but this time it's a virtual currency. To be successful in digging bitcoin, we need to prepare some of the necessary steps and tools. Let's explore this process together.

区块头与挖矿

在比特币挖矿过程中，我们需要创建一个区块头，这是整个挖矿流程的核心。区块头包含了以下关键元素：

In bitcoin mining, we need to create a block, which is at the heart of the entire mining process. The block contains the following key elements:

版本号：用于标记这个区块所使用的比特币协议版本。

Version number: the bitcoin version of the protocol used to mark the block.

前区块哈希：指向前一个已存在的区块，使得区块链成为一个有序的链表。

Hashi: Point to a pre-existing block, making the block chain an orderly chain.

Merkle根：由区块中所有交易构成的Merkle树的哈希值，用来快速校验区块内的交易。

Merklegen: The Hashi value of the Merkle tree, consisting of all transactions in the block, is used to quickly verify transactions in the block.

时间戳：记录了该区块生成的具体时间。

Time stamp: The exact time of generation of the block is recorded.

难度目标：确定挖矿所需的计算量，确保新区块产生的速度适中。

Difficult objective: determine the amount of calculation required to excavate and ensure that new blocks are generated at a moderate rate.

Nonce：随机数，它是挖矿过程中最关键的部分，我们需要找到一个合适的Nonce来满足难度目标。

Nonce: Random numbers are the most critical part of the mining process, and we need to find a suitable Nonce to meet the challenge.

旷工在准备好这些信息之后，就可以生成一个区块头。然而，在比特币系统中，这样的区块头还不具备合法性。

When you get this information ready, you can generate a block head. In the Bitcoin system, however, such blocks have no legitimacy.

为了使区块头得到认可，我们需要找到该区块的哈希值，并将它广播给整个网络。当全网都确认该区块有效后，我们将它连接到现有的区块链上，从而形成一个新的区块链，这也就是所谓的"挖矿"。

In order for the block to be recognized, we need to find the Hashi value of the block and broadcast it to the entire network. When the whole network confirms that the block is valid, we connect it to the existing block chain, thus forming a new block chain, the so-called "mining."

简而言之，每一个旷工都可以尝试生成区块头，但在找到合法的哈希值之前，他们所创建的区块都被认为是"假区块"。一旦某位旷工找到了有效的哈希值，他的"假区块"就变成了"真区块"，并被比特币系统正式承认，同时他还能够获得相应的比特币奖励。

In short, every absentee can try to create blocks, but the blocks they create are considered to be "false blocks" until a valid Hashi value is found. Once a absentee has found a valid Hashi value, his "false blocks" become "real blocks" and are officially recognized by the Bitcoin system, and he can receive the corresponding bitcoin reward.

寻找区块哈希值的方法

现在，我们已经知道挖矿的目标是找到符合要求的区块哈希值。那么问题来了，我们应该如何去寻找这个哈希值呢？

Now, we know that the objective of mining is to find the desired Hashi value. So the question is, how are we going to find this Hashi value?

实际上，寻找区块哈希值的过程非常依赖于猜测。具体来说，我们需要找到区块头中的Nonce，使得经过哈希计算后的结果小于难度目标。

In fact, the search for the Hashi value of a block relies heavily on speculation. Specifically, we need to find Nonce in the block, making it less difficult to calculate.

让我们以区块高度277316为例，假设难度目标为0x1745fb53。在这个例子中，我们需要找到这样一个Nonce值，将其代入哈希计算公式，得到的结果小于目标哈希值。

Let us take the example of block height 277316, assuming that the goal of difficulty is 0x1745fb53. In this case, we need to find such a Nonce value and replace it with a Hashi formula, with a result less than the target Hash value.

为了便于理解，我们可以简化一下哈希计算公式:

For ease of understanding, we can simplify the Hashi formula:

在这个公式中，()内的数值代表Nonce，右侧则是经过哈希运算后的结果。我们可以通过不断地增加Nonce的值，然后将新的值带入公式进行哈希计算，直到找到满足条件的Nonce。

In this formula, the values in () represent Nonce, and the right is the result of Harshi's calculation. We can add the value of Nonce over time, and then bring the new value into the formula for Hashi's calculation until Nonce, which meets the conditions, is found.

需要注意的是，哈希运算本身是非常随机且不可预测的。即使Nonce只增加了1，哈希计算后的结果也可能相差甚远。因此，我们只能不断地试错，直到找到合适的Nonce。

What needs to be noted is that the Hashi calculations themselves are very random and unpredictable. Even if Nonce increases by only one, the results of Hashi’s calculations may be very different. So we have to keep trying to make mistakes until the right Nonce is found.

在我们的例子中，我们终于在Nonce值为924591752时得到了一个符合要求的哈希值：

In our case, we finally obtained a desirable Hashi value at Nonce's value of 924,559,1752:

将这个哈希值与目标哈希值进行比较：

Compare this Hashi value with the target Hashi:

因为这个哈希值的前若干个零与目标值相等，说明我们已经找到了正确的Nonce。

Because the first few zeros of this Hashi value are equal to the target, which means that we have found the right Nonce.

下一步，旷工需要将找到的Nonce值填入区块，并将该区块添加到区块链中。然后，他需要将这个新区块广播给其他节点进行验证。

Next, you need to fill the Nonce value found in a block and add the block to the block chain. He then needs to broadcast the new block to another node for validation.

验证过程相对简单，只需要将找到的Nonce值再次代入公式进行哈希计算，对比计算结果与目标哈希值，就能判断出是否符合要求。值得注意的是，比特币挖矿可能需要进行数十亿次的计算，而验证答案只需一次计算即可完成。

The validation process is relatively simple, and requires a Hashi calculation of the found Nonce value against the target. It is worth noting that Bitcoin mining may require billions of calculations, which can be done only once.

总之，比特币挖矿是一个充满挑战和探索的过程。旷工们需要耐心地寻找合适的Nonce值，经过哈希运算后将哈希值填充到区块中，并广播给全网进行验证。只有通过了严格的验证，旷工们才能够获得宝贵的比特币奖励。

In short, bitcoin mining is a challenging and exploratory process. Frogs need to be patient in finding the right Nonce value, filling the Hashi value in blocks after Hashi calculates, and broadcasting it to the whole network for validation.
