The marriage of a man and a woman is essentially an arrangement of property relations. It involves the power and obligation between the two families, the immediate arrangement of property and the future succession of power, and the recognition of all social relations. The wedding was not for the two men, but for everyone to see. It's perfect for explaining bitcoin.
一男一女的婚姻，本质上是结成一种财产关系的安排。它牵涉到两个家族之间的权力、义务、当下的财产安排和未来的继承权力，需要得到所有社交关系的承认。婚礼，不是办给这两个人看的，是办给大家看的。这太适合解释比特币了。
In fact, bitcoin is a password algorithm. According to this algorithm, the total amount of bitcoins can be calculated is constant, one can not be more. So, when you take it as a currency, there is no risk of inflation, credit is very good. However, non replicability is the most basic characteristic of money. When everyone's money can be copied, the money is worthless.
其实，比特币就是一套密码算法。根据这套算法，能算出来的比特币总量是恒定的，一个也不能多。所以，拿它当货币，就没有通货膨胀的风险，信用非常好。可是，不可复制性是货币最基础的特性。当每个人的钱都能被复制，钱就不值钱了。
Bitcoin technology, the core is to solve this problem. In the virtual digital world, the uniqueness of a string of code is realized and cannot be replicated. In bitcoin systems, there is a "distributed" book".
比特币的技术，核心就是解决了这个问题。在虚拟的数字世界，实现了一串代码的唯一性问题，不可复制。在比特币系统里，有一种“分布式账本”。
That is to say, every bitcoin transaction in the world can be witnessed by every bitcoin. When you use it, it's actually done with the common record and confirmation of the whole bitcoin network. Which account gives the number of bitcoins to another account, where everyone is on record, and there is no question of forgery or duplication of payments.
也就是说，全世界所有比特币的每一笔交易，都能被每个比特币见证。你在使用它的时候，其实是在整个比特币网络的共同记录和确认下完成的。哪个账户把多少比特币给到了另外哪个账户，大家都记录在案，不可能出现伪造或者重复支付的问题。
So bitcoin is virtual, but it's more powerful than the counterfeit money in the old currency. That's the basic principle. Eric Schmidt, chairman of Google, once praised: "bitcoin encryption technology is very amazing.". It can create something that can not be copied in the digital world, which is a remarkable step forward."
所以，比特币虽然是虚拟的，但是它比旧式货币的防伪功能更为强大。这就是它的基本原理。谷歌董事长埃里克·施密特，就曾赞不绝口地说：“比特币的加密技术非常了不起。它能够在数字世界创造一些不可复制的东西，这是一个了不起的进步。”
