: Readers! As a creator of a financial article, I will next read a series of articles about digital money, which will be the first in the series, the second on the subject of “other digital currencies”, and welcome attention to my subsequent series of content, as well as comments on other issues, which will be read in response or in writing.

• 区块链

  Block Chain

区块链是一种去中心化的数据库，由多个节点共同维护。每个节点都有一份完整的区块链副本，任何节点都可以向区块链中添加新的交易。当一个新的交易被添加到区块链中时，它需要被其他节点验证才能被认可。如果交易被验证通过，那么它就会被写入新的区块中，并通过哈希值与前一个区块连接起来，形成一个不可篡改的链条。

The block chain is a decentralised database that is maintained by multiple nodes. Each node has a complete copy of the block chain, and any node can add a new transaction to the block chain. When a new transaction is added to the block chain, it needs to be validated by another node in order to be accepted. If the transaction is verified, it will be written into the new block and linked to the previous one by the Hashi value, forming an irrevocable chain.

区块链的去中心化特性使得它具有高度的安全性和可靠性，因为没有单一的机构或个人能够控制整个系统。同时，区块链也具有高度的透明性和可追溯性，因为每个交易都会被记录在区块链上，并且任何人都可以查看区块链中的交易记录。

The decentralized nature of the block chain gives it a high degree of security and reliability, as no single agency or individual can control the system. At the same time, the block chain is highly transparent and retroactive, as each transaction is recorded on the block chain and anyone can see the transaction records in the block chain.

• 共识机制

  Consensus mechanism

共识机制是指在分布式系统中，通过一定的规则和算法来保证所有节点之间的一致性。比特币网络中的共识机制是通过工作量证明（PoW）来实现的。在 PoW 中，网络中的节点需要通过解决一个复杂的数学难题来证明自己的工作量，并且需要消耗大量的计算资源来完成这个过程。

A consensus mechanism means that, in a distributed system, consistency between all nodes is ensured through certain rules and algorithms. Consensus in the Bitcoin network is achieved through workload proof (PoW). In PoW, nodes in the network need to prove their workload by solving a complex mathematical dilemma and need to consume a significant amount of computing resources to complete the process.

PoW 的设计初衷是为了防止网络中的节点进行恶意行为，例如双重花费攻击。因为在 PoW 中，如果一个节点想要修改已经写入区块链中的交易记录，那么它需要重新计算整个区块链，这需要消耗大量的计算资源和时间。因此，只有拥有足够算力的矿工才能够成功地修改区块链中的交易记录，从而保证了比特币网络的安全性和可靠性。

PoW was originally designed to prevent malicious acts by nodes in the network, such as double-cost attacks. Because, in PoW, if a node wants to modify a transaction record that is already in the block chain, it needs to recalculate the whole block chain, which takes a great deal of computing resources and time.

• 挖矿过程

  Mining process

比特币网络中的挖矿过程是指通过计算来创建新的比特币，并验证和记录交易。挖矿需要大量的计算资源，因此只有具备足够算力的矿工才能参与挖矿。挖矿过程中，矿工需要解决一个复杂的数学难题，这个数学难题是通过不断调整难度系数来保证网络中新区块产生的速度稳定。

The mining process in the Bitcoin network refers to the creation of new bitcoins by means of calculations and the validation and recording of transactions. Mining requires a great deal of computing resources, so that only miners with sufficient capacity can participate in mining.

矿工通过解决数学难题来创建新的区块，并将新区块添加到区块链中。当一个新的区块被添加到区块链中时，矿工会获得一定数量的比特币作为奖励。同时，矿工还可以收取交易手续费作为报酬。

The miners create new blocks by solving mathematical problems and adding new blocks to the block chain. When a new block is added to the block chain, the union gets a certain amount of bitcoins as an incentive. At the same time, the miners can also charge transaction fees as a reward.

挖矿过程是比特币网络中最核心的技术之一，它不仅保证了比特币网络的安全性和可靠性，还促进了比特币经济系统的运行和发展。

The mining process is one of the most central technologies in the Bitcoin network, which not only ensures the safety and reliability of the Bitcoin network, but also contributes to the operation and development of the Bitcoin economic system.

• 结论
  

  Conclusion

比特币工作原理是由区块链、共识机制和挖矿过程三部分组成的。区块链是一种去中心化的数据库，由多个节点共同维护，并保证了交易记录的透明性和可靠性。共识机制是通过工作量证明（PoW）来实现的，可以保证网络中所有节点之间的一致。

The Bitcoin working principle consists of a block chain, a consensus mechanism, and three parts of the mining process. The block chain is a decentralised database that is maintained by multiple nodes and ensures the transparency and reliability of transaction records.
