CPU挖矿是指利用计算机中央处理器（CPU）进行虚拟货币的挖矿活动。在早期，比特币等虚拟货币的挖矿主要依靠CPU完成，但随着虚拟货币的发展和挖矿算法的不断升级，CPU挖矿逐渐被更高效的挖矿方式所取代。
& nbsp; & nbsp; CPU mining is a virtual currency mining operation using a computer central processor (CPU). At an early stage, the mining of virtual currency, such as Bitcoin, was largely done by CPU, but with the development of virtual currency and the upgrading of mining algorithms, CPU mining was gradually replaced by a more efficient method of mining

CPU挖矿是指使用计算机的中央处理器（CPU）进行虚拟货币的挖矿活动。CPU作为计算机最重要的组件之一，可以执行各种计算任务，包括解密算法、数据处理等，因此也可以用于虚拟货币的挖矿过程。
CPU mining refers to the use of computer central processors (CPUs) for virtual currency mining. CPUs, as one of the most important components of computers, can perform various computing tasks, including decryption algorithms, data processing, etc., and can therefore also be used in virtual currency mining processes.
CPU挖矿的原理是通过计算复杂的算法来验证和记录虚拟货币交易的有效性，并获得挖矿奖励。挖矿算法通常采用哈希函数，通过对数据进行多次哈希计算，找到符合一定条件的哈希值，从而获得激励。
The rationale behind CPU mining is to verify and record the validity of virtual currency transactions by calculating complex algorithms, and to get incentives to do so.
- 初期代表性：在比特币诞生初期，CPU挖矿是最主要的挖矿方式之一，对于早期参与者具有一定的优势。
- Initial representation: in the early days of Bitcoin, CPU mining was one of the most important forms of mining, with some advantages for early participants.
- 低门槛：CPU挖矿相对较为简单，对于普通计算机用户来说，只需下载合适的挖矿软件并进行配置即可参与挖矿。
- Low threshold: CPU mining is relatively simple and, for ordinary computer users, can only be involved in mining by downloading and configuring suitable mining software.
- 兼容性强：由于CPU是计算机的核心组件，几乎所有计算机都配备了CPU，因此CPU挖矿具有广泛的兼容性。
- High compatibility: Since CPU is the core component of the computer, almost all computers are equipped with CPUs, CPU mining is broadly compatible.
- 效率低下：相比于其他挖矿方式如GPU挖矿和ASIC挖矿，CPU挖矿的算力较低，无法满足虚拟货币网络的高算力需求。随着挖矿竞争的加剧，CPU挖矿逐渐被淘汰。
- Inefficiency: CPU mining is less arithmetic than other mining methods, such as GPU mining and ASIC mining, and does not meet the high demand for virtual monetary networks. As mining competition increases, CPU mining is phased out.
- 能耗高：CPU挖矿的功耗较大，与挖矿所获得的回报相比，能耗成本过高。
- Energy consumption: CPU mining is more expensive and expensive than the returns from mining.
- 算力不足：虚拟货币的挖矿算法经过升级和演进，要求更高的算力才能完成挖矿任务。而CPU的算力相对有限，已无法满足当前的挖矿需求。
- Insufficient arithmetic: Virtual currency mining algorithms have been upgraded and evolved, requiring higher arithmetic to complete mining tasks. CPUs have a relatively limited arithmetic and are no longer able to meet current mining needs.
- GPU挖矿：通过使用显卡（GPU）来进行挖矿活动，相比CPU挖矿有更高的算力和效率。
- GPU mining: mining activities through the use of video cards (GPUs) are more cost-effective and efficient than CPU mining.
- ASIC挖矿：专门设计用于虚拟货币挖矿的集成电路，具有更高的算力和能效比，已经成为主流的挖矿方式。
- ASIC Mining: Integrated circuits specially designed for use in virtual currency mining, with higher arithmetic and energy efficiency, have become the dominant method of mining.
CPU挖矿在比特币诞生初期被广泛应用。早期的比特币挖矿算法（SHA-256）相对简单，计算量较小，因此利用计算机CPU进行挖矿是可行且有效的方式。当时只需运行比特币挖矿软件，即可通过CPU进行挖矿并获得一定数量的比特币作为奖励。
The early bitcoin mining algorithm (SHA-256) was relatively simple, with smaller calculations, and therefore the use of computer CPU for mining was a viable and effective way to do it. By operating the bitcoin mining software, it was possible to dig through the CPU and get a certain amount of bitcoin as an incentive.
- 步骤1：计算哈希值
- Step 1: Calculating Hashi.
CPU挖矿的关键是计算哈希值，即对一组数据进行多次哈希运算。哈希运算将数据转换为固定长度的字符串，不同的输入数据都会得到唯一的哈希值。挖矿过程中，通过不断更改被哈希的数据以达到目标哈希值。
The key to CPU mining is to calculate the Hashi value, i.e. to perform multiple Hashi calculations of a set of data. Hashi calculates to convert the data into a string of fixed lengths, and the only Hashi value is obtained for different input data. During mining, the Hashi data are constantly changed to reach the target Hashi value.
- 步骤2：增加难度目标
- Step 2: Increasing the objective of difficulty
为了确保虚拟货币网络的安全性和稳定性，挖矿过程设置了一个目标哈希值。参与挖矿的计算机需要通过计算生成的哈希值与目标哈希值进行比较，如果找到的哈希值小于目标值，则成功挖矿。
In order to ensure the security and stability of the virtual monetary network, a target Hash value is set for the mining process. Computers involved in mining are required to compare the Hash value generated with the target hash value, and if the Hashi value is found to be less than the target value, the mine is successfully mined.
- 步骤3：验证和记录交易
- Step 3: Validation and recording of transactions
挖矿过程中，CPU挖矿算法会不断验证和记录虚拟货币网络中的交易。只有在完成验证的前提下，交易才能被确认并添加到区块链中。同时，挖矿活动还会产生新的货币作为奖励，这也是挖矿参与者的收入来源之一。
During mining, CPU mining algorithms constantly validate and record transactions in virtual currency networks. Only when certified can transactions be identified and added to block chains.
随着虚拟货币行业的发展和挖矿技术的进步，CPU挖矿的地位已经逐渐式微。现阶段，比特币等一些主流虚拟货币已经采用了更复杂的挖矿算法（如SHA-256），要求更高的算力，无法通过CPU进行有效挖矿。因此，大多数挖矿者转向了更专业化的挖矿方式，如GPU挖矿和ASIC挖矿。
At this stage, some mainstream virtual currencies, such as Bitcoin, have adopted more sophisticated mining algorithms (e.g. SHA-256) that require higher arithmetic than effective mining through CPU. As a result, most diggers have turned to more specialized mining methods, such as GPU and ASIC.
- GPU挖矿：相比CPU挖矿，GPU挖矿具备更高的算力，能够更有效地完成挖矿任务。但相对于ASIC挖矿，GPU挖矿仍然存在一定的算力瓶颈和功耗较高的问题。
- GPU digs: GPU digs are more arithmetic than CPU digs, and is more effective in carrying out mining tasks. However, there are still some problems of arithmetic bottlenecks and high productivity in GPU digs than ASIC digs.
- ASIC挖矿：ASIC挖矿专门设计用于虚拟货币挖矿，具备更高的算力和能效比。相较于CPU和GPU，ASIC芯片专注于挖矿算法，因此在挖矿效率和功耗方面具备绝对优势。然而，ASIC挖矿也容易导致中心化问题，使得少部分矿工垄断大量算力，从而影响虚拟货币网络的去中心化特性。
- ASIC digs: ASIC digs are designed for virtual currency digs, with a higher arithmetic and energy efficiency ratio. Compared to CPU and GPU, the ASI chip focuses on mining algorithms, and thus has an absolute advantage in mining efficiency and utility. However, ASIC digs can also easily lead to centralization problems, allowing a small number of miners to monopolize large amounts of algorithms, thus affecting the decentralization character of virtual money networks.
CPU挖矿作为虚拟货币行业的早期挖矿方式，为这一领域的发展奠定了基础。不可否认的是，随着技术的进步，CPU挖矿已经被更高效的挖矿方式所取代。然而，CPU挖矿在历史上起到重要的推动作用，为后续的GPU挖矿和ASIC挖矿技术铺平了道路。
CPU mining, as an early method of mining in the virtual money industry, has laid the foundation for development in this area. It is undeniable that, with technological advances, CPU mining has been replaced by more efficient methods of mining.
CPU挖矿在虚拟货币挖矿领域已经不再是主流，但它代表了虚拟货币行业的早期发展历程。随着科技的进步和挖矿算法的不断更新，虚拟货币的挖矿方式也在不断演进。未来，更高效的挖矿方式将逐渐取代过时的方式，推动整个行业向前发展。
CPU mining is no longer the mainstream in virtual money mining, but it represents the early development of the virtual money industry. As technology advances and the mining algorithms continue to evolve, so does the way in which virtual money is mined.
