「比特百问百答」什么是比特币？

比特币（英语：Bitcoin，简写：BTC，货币符号：?），是一种用开源的 P2P 技术的软件而产生的电子货币。

Bitcoin (English: Bitcoin, short: BTC, Currency Symbols:?) is an electronic currency generated from open-source P2P technology software.

和传统货币最大的不同是，作为一种建立在全球区块链网络上的数字货币，比特币的发行依赖区块链网络的正常运行, 人们只需要运行比特币软件，就可以参与比特币的制造，这种方式被称为“挖矿”。

The biggest difference between traditional currencies is that, as a digital currency built on a global block chain network, Bitcoin's distribution depends on the normal operation of the block chain network, people simply have to run bitcoin software and can participate in the production of bitcoin, known as “mining”.

比特币没有一个中央发行机构比特币是人类历史上第一次进行去中心化的货币系统，比特币的交易信息不受任何组织和个人控制，在理论上确保了任何人、机构、或政府都不可能篡改比特币交易双方的交易内容。

Bitcoin did not have a central issuer, Bitcoin, a decentralised monetary system for the first time in human history, and information about Bitcoin transactions was not controlled by any organization or individual, ensuring in theory that no person, institution or Government could alter the content of transactions between the two sides of the Bitcoin deal.

比特币具有货币属性包含支付特性和自我完善的货币体制。

Bitcoins have monetary attributes that include payment characteristics and self-improvement of the monetary system.

如果说这样的解释有点看不懂的话，为了帮助大家理解，我们的首先从货币的发展史开始说起，货币一开始是实物货币，贝壳、金银等，因为他们具有稀缺性，用于充当一般等价物。后来我们开始用纸币进行支付。

If such an explanation is somewhat confusing, in order to help you understand that, first of all, starting with the history of monetary development, currencies are in kind, shells, gold, etc., because they are scarce and are used as generic equivalents. Then we start paying in banknotes.

随着互联网的发展，我们从纸币过度到记账货币，比如发工资只是在银行卡账户上做数字的加法，买衣服只是做减法。整个过程中都是银行在记账，且只有银行有记账权。

With the development of the Internet, we have gone from banknotes to the currency of accounts, for example, where wages are added to the bank card account, and clothing purchases are reduced. The whole process is done by the bank, and only the bank has the right to account.

再后来出现了智能手机移动互联网应用，例如微信支付、支付宝支付这样更加便捷化的第三方担保公司来给我们记账，我们交易只是在由微信、支付宝这样第单方担保的账户上面进行数字的加减。

Then there were mobile Internet applications of smartphones, such as micro-mail payments, payment of treasures, and more convenient third-party guarantee companies to account for us, and we traded only to add to or subtract figures from accounts with first-party guarantees such as micro-mails, payment of treasures.

这样还是存在一个中心(国家银行、支付宝、微信)，如果发生天灾，例：这些第三方的服务器受到损坏，那我们的记录就会被销毁，交易无法查询。同时由国家发行的法定货币存在超印的情况，会引起通货膨胀。

There is still a centre (national bank, payment treasure, micro-mail) where, in the event of a natural disaster, for example, the servers of these third parties are damaged, our records are destroyed and our transactions are untraceable. At the same time, there is overprinting of the legal currency issued by the state, which causes inflation.

在2008全球经济危机中，美国政府因为有记账权所以可以无限增发货币。“比特币”的概念最初由中本聪（Satoshi Nakamoto，可能化名）在 2009 年提出，中本聪觉得这样很不靠谱，于是他想创建一种新型支付体系：大家都有权来记账，货币不能超发，整个账本完全公开透明，十分公平。

In the global economic crisis of 2008, the US government was able to increase its currency indefinitely because it had the right to keep accounts. The concept of “bitcoin” was first proposed by Satoshi Nakamoto in 2009, and China’s thinking of creating a new payment system: everyone has the right to account, the money cannot be overpaid, and the entire account book is completely transparent and fair.

于是就出现了比特币这样去中心，点对点支付的数字货币。我们把抢记账权从而获得比特币奖励的过程，称为挖矿。现在比特币也指根据中本聪的思路设计发布的开源软件以及建构其上的整个 P2P 网络。

So there's Bitcoin going to the center, and point-to-point digital money. We call the process of getting a bitcoin reward, which we call mining. Bitcoin now also refers to the open source software that is designed to be released along the same lines as the entire P2P network on which it is based.

比特币使用遍布整个 P2P 网络节点的分布式数据库来管理货币的发行、交易和账户余额信息。中本聪采用密码学的原理，确保各个比特币节点按照既定的协议达成共识，从而确保货币流通各个环节的安全性。例如，比特币只能被它的真实拥有者使用，而且仅仅能使用一次，支付完成之后原主人即失去对该份额比特币的所有权。

Bitcoin uses a distributed database covering the entire P2P network nodes to manage information on currency distribution, transactions and account balances. China’s Bints use cryptography to ensure consensus among the Bitcoins nodes in accordance with established agreements, thus ensuring the security of the various links in the currency flow. For example, Bitcoins can only be used once and the original owner loses ownership of the bitcoin when the payment is completed.

比特币与其他虚拟货币最大的不同，是其总数量是非常有限的，具有极强的稀缺性。该货币系统在前4年内只有不超过1050万个，之后的总数量将被永久限制在2100万个之内。还有一点是，任何互联网用户都可以用电脑生产比特币。返回搜狐，查看更多

The biggest difference between Bitcoin and other virtual currencies is that its total number is very limited and extremely scarce. In the first four years, the monetary system has not exceeded 10.5 million, and the total number will be permanently limited to 21 million. And one thing is that any Internet user can produce bitcoin with a computer. icras="backsohu return to the fox search for more
