比特币定义
bitcoinDefinitions
比特币(BTC)是一种数字货币，以电子方式使用和分发。比特币是一个去中心化的点对点网络。没有任何一个机构或个人可以控制它。比特币无法打印，而且数量非常有限-只能创建2100万比特币。
Bitcoin is a digital currency that is used and distributed electronically. Bitcoin is a decentralised point-to-point network. No institution or individual can control it. Bitcoin is impossible to print and very limited - it can only create 21 million bitcoins.
谁创造了比特币?
Who created Bitcoin?
比特币最初是由匿名程序员或一组程序员以中本聪(Satoshi Nakamoto)的名义在2009年作为开源软件引入的。关于BTC创造者真实身份的传闻很多，但是所有人都提到了在那些谣言中公开否认是中本聪。
Bitcoin was originally introduced in 2009 by anonymous programmers or a group of programmers in the name of Satosh Nakamoto as open source software. There were many rumors about the true identity of the creators of the BTC, but all mentioned that the public denials in those rumours were neutron.
中本人曾经声称自己是居住在日本的37岁男性。但是，由于他的英语水平很好并且其软件没有用日语标记，因此对此存在合理的怀疑。在2010年中左右，Nakamoto转向了其他事情，将比特币交由BTC社区的一些杰出成员掌握。Satoshi还任命Gavin Andresen为首席开发人员。
In mid-2010, Nakamoto turned to something else, leaving Bitcoin in the hands of some prominent members of the BTC community. Satoshi also appointed Gavin Andresen as chief developer.
据估计，中本聪拥有约一百万个比特币，截至2017年9月，约合36亿美元。
It is estimated that Nakamoto owns about 1 million bitcoins, or about $3.6 billion as of September 2017.
谁控制比特币?
Who controls Bitcoin?
根据加文·安德烈森(Gavin Andresen)的说法，中本聪离开该项目后，他关注的第一件事就是进一步的权力下放。安德森(Andersen)希望比特币能够自动继续存在，即使他会“被公共汽车撞”。
According to Gavin Andresen, his first concern after Nakamoto left the project was further decentralization. Andersen hoped that Bitcoin would continue automatically, even if he would “be hit by a bus.”
对于很多人来说，比特币的主要优势在于它独立于世界各国政府，银行和企业。没有哪个机构可以干预BTC交易，征收交易费或带走人们的钱。此外，比特币的移动是极其透明的-每笔交易都存储在称为区块链的大规模分布式公共分类帐中。
For many, the main advantage of Bitcoin is that it is independent of governments, banks, and businesses around the world. No agency can interfere with BTC transactions, collect transaction fees or take people’s money. Moreover, the movement of Bitcoin is extremely transparent – every transaction is stored in a large-scale public ledger known as a block chain.
从本质上讲，虽然比特币并未作为网络受到控制，但它使用户可以完全控制自己的财务状况。
In essence, while Bitcoin is not controlled as a network, it allows users to fully control their financial situation.
比特币如何运作?
How does Bitcoin work?
用户在他或她的钱包和交易结果上只能看到少量的比特币。
The user can only see a small amount of bitcoin on his or her wallet and transaction results.
在幕后，比特币网络共享一个称为“区块链”的公共分类帐。该分类帐包含曾经处理的每笔交易。交易的数字记录被组合成“块”。
Behind the scenes, the Bitcoin network shares a public ledger called the Block Chain. The ledger contains every transaction that has been processed. The digital record of the transaction is combined into a block.
如果某人尝试在一个交易块中仅更改一个字母或数字，也会影响以下所有块。由于它是公共分类帐，任何人都可以很容易地发现并纠正错误或欺诈企图。
If someone tries to change only one letter or number in a trade block, it also affects all of the following. Because it is a public ledger, anyone can easily detect and correct errors or fraudulent attempts.
用户的钱包可以验证每笔交易的有效性。每个交易的真实性受与发送地址相对应的数字签名保护。
The user’s wallet can verify the validity of each transaction. The authenticity of each transaction is protected by a digital signature corresponding to the address sent.
由于验证过程的不同，并且取决于交易平台，BTC交易可能需要几分钟才能完成。比特币协议的设计目的是使每个区块挖掘大约10分钟。
Because of differences in the validation process, and depending on the trading platform, the BTC transaction may take a few minutes to complete. The Bitcoin protocol is designed to dig each block for approximately 10 minutes.
