直到，2010年5月18日，一位名叫Laszlo Hanyecz的程序员在比特币论坛上表示希望用一万枚比特币换取两份Papa John’s的大披萨（当时价值40美元）。随后逐渐有人注意到了这个帖子，3天之后，密码学爱好者jercos，趁商家优惠，花了25美元购买两份披萨寄给Laszlo，并按承诺获得了一万枚比特币。
Bitcoin Pizza Festival, do you know how it came?
The day is May 22, which is a special day for Bitcoin believers.
Ten years ago, May 22 was the day when Bitcoin was first priced. Only then did Bitcoin begin to truly have the value of exchange, so this day became the anniversary of Bitcoin, known as Bitcoin Pizza Festival.
As for the origin of the Bitcoin Pizza Festival, there is a very interesting little story behind it. After the founder of Bitcoin, Satoshi Nakamoto, invented Bitcoin, there are still very few people who really know and use Bitcoin in the world. For a long period of time, Bitcoin was the exchange of discussions between crypto geeks. topic of.
Until May 18, 2010, a programmer named Laszlo Hanyecz expressed in the Bitcoin Forum that he hoped to exchange 10,000 bitcoins for two Papa John ’s large pizzas (valued at $ 40). Then someone gradually noticed this post. Three days later, cryptography enthusiast jercos, taking advantage of the merchant's discount, bought two pizzas for $ 25 and sent them to Laszlo, and received 10,000 bitcoins as promised.

Although Laszlo's post was published on the 18th, May 22 was the real trading time. People chose the trading day as the official commemorative day. Therefore, May 22 was named "Bitcoin Pizza Festival".
According to the price of the pizza purchased at the time, the initial price of Bitcoin was 0.004 US dollars. The current price of Bitcoin is about 9700 US dollars, which is a 2425,000-fold increase from the price at that time, and the 10,000 bitcoins at that time are now worth 97 million US dollars Looking at the current exchange rate of RMB to USD, the conversion to RMB is about 680 million, and the one who uses bitcoin for pizza is a missed billionaire. Throughout human economic history, Bitcoin's two-million-fold return on investment is probably nothing. I don't know what Laszlo's mood is when he sees the price of Bitcoin now? But it is this transaction that seems expensive today, bringing Bitcoin to the real world for the first time.

Bitcoin is a highly liquid currency that is traded globally. This is an emerging asset class that has risen from US $ 0 billion to US $ 200 billion in 10 years. There is no venture capital support, no IPO, no corporate entity, no founding People, there is no pure open source organization to maintain.
With the birth of Bitcoin, it has also laid the mainstream basic direction of using cryptography as a digital currency. The concept of digital currency began at this time and was well known to the public. And Bitcoin has a huge impact on the current blockchain system, because Satoshi Nakamoto gave the blockchain a particularly important property in the process of landing Bitcoin, which is decentralization. Everyone can participate in this set of mechanisms, with equal rights, no centralized team or agency intervention, and once the data is recorded, it cannot be changed at all.
Bitcoin and blockchain are like chickens and eggs. The relationship between eggs and chickens is precisely because of the existence of blockchain, so that bitcoin can run smoothly, and it is precisely because of the application of bitcoin that it can be lifted. Opening the veil of blockchain has us ushered in an era of rapid development of blockchain technology.
It has been ten years since the birth of Bitcoin, and whether it is an amazing increase of 2 million times, or a blockchain technology that has changed the world, it is worth remembering. Today is May 22, 2020, and the ninth Bitcoin Pizza Festival. This festival will always stand above the history of Bitcoin as an important milestone.
