与人们对于比特币的普遍认知相反，比特币和任何其他形式的货币一样有价值支撑，比特币背后也是由其货币可信度作为价值支撑。货币不是人类的集体幻觉抑或是信仰体系。

Contrary to the general perception of bitcoin, bitcoin is as valuable as any other form of currency, and its value is supported by its currency credibility. Money is not a collective illusion or a belief system.

在人类的整个历史进程中，各种各样的交换媒介都曾以货币的形式出现，但每一次出现都不是偶然。所有以货币形式出现的商品都具有区别于其他市场商品的独特属性。

In the whole process of human history, all kinds of media of exchange have appeared in the form of currency, but each time they appear is not accidental. All commodities in the form of money have unique properties which are different from other market commodities.

《The Bitcoin Standard》一书中对此提出了更广泛的讨论，商品货币的稀缺性、耐用性、便携性、可分割性、可互换性和可验证性等都导致其特别适合用来作为交易媒介。

The book "the bitcoin standard" puts forward a broader discussion on this issue. The scarcity, durability, portability, separability, interchangeability and verifiability of commodity currency make it particularly suitable for trading medium.

每当一种新兴货币出现时，货币作为交易媒介的固有属性都会在原有货币形式的基础上得到改进，而原有的货币则会被逐渐抛弃，退出流通市场。货币竞争的本质是一种货币的优势胜过另一种货币。比特币也不例外，比特币是全球货币竞争中的产物，它是黄金和由黄金支撑的法定货币体系的优秀继承者。

When a new currency appears, the inherent property of money as a medium of transaction will be improved on the basis of the original currency form, while the original currency will be gradually abandoned and exit the circulation market.The essence of currency competition is that one currency is superior to another. Bitcoin is no exception. Bitcoin is the product of global currency competition. It is the excellent successor of gold and the legal system supported by gold.

比特币优秀的货币属性超越了其他货币，比特币极其稀缺，比现有的货币更容易分割和交换，同时比特币也更加去中心化，作为一种衍生特性比特币更抗审查。世界上比特币的总量只有2100万枚，每个比特币可以被分割至1亿分之一。通过比特币的区块链网络我们可以在未经许可的基础上转账给世界任何人，并且不依赖任何第三方进行结算。

Bitcoin's excellent monetary attributes surpass other currencies. Bitcoin is extremely scarce, and it is easier to be divided and exchanged than existing currencies. At the same time, bitcoin is also more decentralized. As a derivative feature, bitcoin is more resistant to censorship.There are only 21 million bitcoins in the world, and each bitcoin can be divided into one hundred million. Through bitcoin's blockchain network, we can transfer money to anyone in the world on an unauthorized basis without relying on any third party for settlement.

其实，2009年比特币诞生后，在很长一段时间里，都是没有价格的。因为在那个时间节点，整个社会对数字货币的概念，都存在不小的质疑，只有小部分的技术极客，被比特币的理念所吸引，才参与到比特币挖矿之中。

In fact, after the birth of bitcoin in 2009, there was no price for a long time. Because at that time point, the whole society had a lot of doubts about the concept of digital currency. Only a small number of technical geeks, attracted by the concept of bitcoin, participated in bitcoin mining.

被披萨赋予的价值

比特币真正意义上被赋予价格日子，则是在2010年1月，当时在比特币早期论坛BitcoinTalk上，有一位叫做“dwdollar”的人表示，他想要创建一个以比特币作为商品的全新市场，人们可以在里面自由地买卖比特币。于是在2010年3月17日，第一家数字货币交易所诞生，比特币在上线时的价格被定为0.003美元，第一次，比特币有了统一的价格。

The date when bitcoin was really given a price was in January 2010. At that time, on the bitcoin early forum bitcoin talk, a person named "dwdollar" said that he wanted to create a brand-new market in which bitcoin was used as a commodity, in which people could freely buy and sell bitcoin. So on March 17, 2010, the first digital currency exchange was born. The price of bitcoin was set at $0.003 when it went online. For the first time, bitcoin had a unified price.

可价格并不能证明比特币的内在价值，真正令比特币展现其支付属性的，则是两个月之后的一场社会实验，而这场社会实验日后还有另一个名字，就是著名的比特币披萨日。

However, price can not prove the intrinsic value of bitcoin. What really makes bitcoin show its payment attributes is a social experiment two months later, and this social experiment will have another name, namely, bitcoin pizza day.

之所以把这个日子定为纪念的节日，除了天价披萨的典故外，还有一个值得纪念的原因是这是比特币进行的第一笔消费交易。尽管这笔交易并非我们想象的那样直接把比特币付给披萨店或者送餐员那么简单，中间经历了不少的波折和旁观者的嘲讽，但是最终还是达成了现实中比特币的第一笔交易。

In addition to the allusions of priceless pizza, the reason why this day is regarded as a commemorative holiday is that this is the first consumption transaction of bitcoin. Although the deal was not as simple as we thought it would be to pay bitcoin directly to a pizza parlor or a delivery person, and experienced many twists and turns and the ridicule of bystanders, it finally reached the first transaction of bitcoin in reality.

时间回到2010年5月18日，还是在BitcoinTalk这个论坛，当时有一位叫做Laszlo Hanyecz的程序员发了个帖子，说他想要用比特币来购买披萨，他的原话是这样的：“我想要2块大披萨，希望能用10000枚比特币来换。披萨可以是从商店购买的，也可以是自制的。但是我需要你把披萨送到我的家门口，就像酒店的餐饮服务一样，不需要我自己准备并购买。我喜欢洋葱、胡椒、香肠和蘑菇，不要奇怪的鱼肉披萨”！

Back on May 18, 2010, on the bitcoin talk forum, a programmer named Laszlo hanyecz sent a post saying that he wanted to buy pizza with bitcoin. His original words were as follows: "I want two large pizzas, and I hope I can exchange them with 10000 bitcoins. Pizza can be bought from a store or made in your own house. But I need you to deliver the pizza to my door, just like the restaurant service in a hotel. I don't need to prepare and buy it myself. I love onions, peppers, sausages and mushrooms. Don't make a strange fish pizza "!

可惜的是，这个帖子并没有引发热议，甚至发出去6个小时之后，这个帖子才迎来了它的第一条回帖，在接下来的3天里，陆续有人来围观，但很少有人会询问他的住址，大部分的评论都是质疑和嘲讽，甚至连他本人都产生了怀疑，发帖询问：“没有人想给我买披萨，是因为我提供的比特币数量过低吗？”

Unfortunately, this post did not arouse heated discussion. It was even six hours after it was sent out that the post received its first reply. In the next three days, people came to watch him one after another, but few people would ask for his address. Most of the comments were query and ridicule, and even he himself had doubts. He asked: "no one wants to buy me pizza Is it because the quantity of bitcoin I offer is too low? "

直到2010年5月22日当天下午5点17分，在经历了4天的等待后，Laszlo Hanyecz终于发出了交易成功的帖子，他表示：“我只想告诉大家我成功交易了10000枚比特币换了两块披萨，感谢jercos”！并附上了披萨的照片。

Until 5:17 p.m. on May 22, 2010, after four days of waiting, Laszlo hanyecz finally posted a successful transaction. He said, "I just want to tell you that I successfully traded 10000 bitcoin for two pizzas, thank you jercos"! A picture of the pizza is attached.

这也成为了比特币历史上第一次进行的实物交易。此后，比特币的价格便一发不可收地一路上涨。而大家为了纪念这一天，就将每年的5月22日定为“比特币皮萨日”。

It also became the first physical transaction in bitcoin's history. Since then, the price of bitcoin has gone up all the way. In order to commemorate this day, may 22 is designated as "bitcoin pizza day".

尽管，现在按比特币历史最高价格算起，这两块披萨的价格高达1.6亿美元，可以说是史上最贵的披萨，但也正是因为这笔交易的出现，比特币才展现了他的价值，也完成了中本聪理想中的那个“点对点的电子现金系统”。

Although the price of these two pizzas is as high as US $160 million, which can be said to be the most expensive pizza in history, it is precisely because of the emergence of this transaction that bitcoin shows its value and completes the "peer-to-peer e-cash system" that Nakamoto envisions.
