大家好，我是你们的贝尔同学。经过前期的学习，大家对比特币的基本概念有了初步的理解了吧！那么又有新问题了，比特币是怎么交易的呢？今天我们来讲讲比特币的交易机制的问题吧！
Hello, I'm your Bell classmate. After learning, you have a preliminary understanding of the basic concepts of Bitcoin. So there are new questions. How does Bitcoin deal? Let's talk about the trading mechanisms of Bitcoin today.
比特币交易实现的基础是什么？
What is the basis for the realization of the Bitcoin transaction?
什么是比特币交易？简单的说，比特币交易就是一个比特币钱包向另一个钱包转账，在这个转账的过程中，每一笔交易都有数字签名来作为安全防护。只要发生一单交易，那么它对于其他任何人来说都是公开的，每一笔交易所流通的比特币都能够追源到这个比特币最初被挖出来的那个点。
What is a bitcoin deal? Simply put, the bitcoin deal is a bitcoin wallet that is transferred to another wallet, in which every transaction has a digital signature as a security shield. As long as a single transaction occurs, it is open to anyone else, and the bitcoin in every exchange is able to trace it to the point where the bitcoin was first dug up.
在交易的过程中，持有比特币的人需要先拥有一个地址，这个地址就相当于是比特币的钱包，比特币就是钱包里的钱。从一个地址转到另一个地址就是从一个钱包转到另一个钱包。
In the course of the transaction, the person holding the bitcoin needs to have an address first, which is the same as the bitcoin wallet, and the bitcoin is the money in the wallet. Moving from one address to another is moving from one wallet to another.
这个地址的产生与现实中我们的私人身份信息没有一点关系。这意味着在一笔交易中，就算知道了交易双方的地址，别人也并不能根据这个地址确认并找到真正的交易者们。
The creation of this address has nothing to do with our personal identity information in reality. This means that in a transaction, even if you know the address of the parties to the transaction, no one can identify and find the real traders on the basis of that address.
比特币交易是怎么实现的？
How did the Bitcoin deal happen?
比特币交易的过程是通过记录的账本来实现的。比特币是一种虚拟货币，它的转账并不能向现实的货币一样从一个钱包转到另一个钱包。所以，它的交易过程是依靠系统中账本记录来完成的。
The process of dealing in bitcoin is done by recording the accounts. Bitcoin is a virtual currency, and its transfers cannot be transferred from one wallet to another, just like the real currency. So, the course of dealing depends on the records of the system's books.
举一个例子，如果系统记录了A向B转了10个比特币这笔交易,那么我们就可以说B的钱包里收到了A转来的10个比特币，而A的钱包里因为转走了10个币从而减去了10个币。
By way of example, if the system recorded the transfer of 10 bitcoins from A to B, we could say that 10 bitcoins from A were received in B's wallet, and 10 coins were deducted from A's wallet because 10 coins had been transferred.
不同的是，我们目前存在的交易账本系统都具有中心化的特点。例如，我们在通过银行进行交易转账时，账本的记录还有账本的修护就由银行来操作；同样的道理，如果我们通过支付宝来进行交易，那么这些交易账本的记录就由支付宝来运行操作。
The difference is that the transaction book system that we currently have has a central feature. For example, when we transfer transactions through banks, the records of the books and the repair of the books are operated by the banks; similarly, if we make the transactions by paying the treasures, the records of the books of the transactions are operated by paying the treasures.
总而言之，在目前现实的交易中，在什么平台发生交易，就由这个平台来对交易记录进行管理运行。而比特币系统则是去中心化，没有中央机构能够完成这件事，完成账本记录修护的是系统里的其他用户。
In summary, in the case of current transactions, it is the platform that manages the transaction log. The Bitcoin system is decentralised, no central agency can do this, and the rest of the users in the system are completing the bookkeeping repairs.

好啦，我们已经知道了比特币交易的实现基础与方式，现在就让我们具体来看一看实际的操作过程吧！
Well, we already know the basis and manner of making the bitcoin deal. Now let's see what's actually going on.
现在，我们要在比特币交易系统中进行一次转账交易。我们需要向系统中的所有节点公示自己的交易信息。在这些公布的信息之中包含着我们自己的地址、转账对象的地址、交易的时间、交易的金额，还有验证自己是地址所有人的信息等等。
Now, we have to make a transfer transaction in the Bitcoin trading system. We need to disclose our transaction information to all nodes of the system. The published information contains our own address, the address of the person to whom the transfer is made, the time of the transaction, the amount of the transaction, and information confirming that we are the owner of the address.
交易双方在收到交易信息之后，会对交易的有效情况进行验证。验证需要经历两个部分；一部分是验证这笔交易确实是由地址的持有者我们发出，确保不是由其他人伪造的；另一部分，验证这个地址所拥有的货币能够支付这次交易。
When the parties to the transaction receive information about the transaction, they verify the validity of the transaction. Validation requires two parts; one part to verify that the transaction is indeed sent by the holder of the address, ensuring that it is not forged by another person; and the other part to verify that the currency in which the address is held is capable of paying for the transaction.
如果以上两部分的验证都能够顺利通过，并且交易双方都对这笔交易没有什么不满，那么比特币系统就会对这次的交易进行记录，这笔交易完成了。
If the certification of both parts were successful and both parties to the transaction were not dissatisfied with the transaction, then the Bitcoin system would record the transaction, which was completed.
以上就是比特币交易机制的内容啦，你们都看懂了吧！
That's what the bitcoin deal is all about. You see?
