2010年的时候,有个程序员花了10000*币特比**买了两张匹萨的事情。这被认为是*币特比**的首笔现实交易。

看着现在*币特比**的行情,10000*币特比**就是一个亿美元。于是我便好奇这位程序员会是什么心情,于是去查了一下这位主人公Laszlo Hanyecz。
在2010年5月18日,Laszlo在*币特比**论坛Bitcoin Forum上发表了一个对后世影响深远的帖子
—— ”披萨换*币特比**?“

I’ll pay 10,000 bitcoins for a couple of pizzas.. like maybe 2 large ones so I have some left over for the next day. I like having left over pizza to nibble on later. You can make the pizza yourself and bring it to my house or order it for me from a delivery place, but what I’m aiming for is getting food delivered in exchange for bitcoins where I don’t have to order or prepare it myself, kind of like ordering a ’breakfast platter’ at a hotel or something, they just bring you something to eat and you’re happy!
(省略...关于他喜欢的披萨食材)
Thanks,
Laszlo
大意是Laszlo希望用10000*币特比**去换一些披萨,最好是两块大的,让他可以留到第二天再吃一顿。愿意交易的人可以自己做两块披萨,也可以去披萨店买两块,然后让外卖小哥送到他家。

bitcoin2paysafe:In which country do you live?
发帖六个小时后,有人问Laszlo住在哪个国家。
May 18, 2010, 06:46:48 PM
laszlo:
Jacksonville, Florida
zip code 32224
United States
Laszlo回答到,在美国佛罗里达州的Jacksonville(注:离我好近啊)。

10,000... Thats quite a bit.. you could sell those on https://www.bitcoinmarket.com/ for $41USD right now..
good luck on getting your free pizza.
接着有人表示,如果Laszlo可以把这些*币特比**卖41刀,所以这笔交易并不划算。
May 21, 2010, 09:33:45 PM
laszlo:I just think it would be interesting if I could say that I paid for a pizza in bitcoins
但这并没有改变Laszlo的决定,他解释道他觉得可以用*币特比**买披萨是一件很酷的事情。
May 22, 2010, 07:17:26 PM
laszlo:I just want to report that I successfully traded 10,000 bitcoins for pizza.

Thanks jercos!
发帖后的两天,Laszlo兴奋的告诉大家,他与一位叫做Jercos的程序员达成了交易,用10000个*币特比**换到了想要的披萨。他还把披萨照片发到了网上,还表示自己一岁的女儿对这些披萨非常满意。

Laszlo发布的披萨照片,史上最贵披萨真容。在论坛上,Laszlo还搞怪的表示,只有披萨是*币特比**换的,小孩是他自己的。
May 22, 2010, 10:10:25 PM
sirius:Congratulations laszlo, a great milestone reached
当时就有人非常精准的意识到,这次交易将会是是一个伟大的里程碑。

Laszlo购买披萨的交易记录
*币特比**的每一笔交易都是透明的。根据Laszlo提供的地址,我们可以查到这笔交易的具体发生时间是2010年5月22日的晚上18:16。
后来的剧情我们都知道了,*币特比**的价格一路疯涨。

knightmb:$600 is a great deal for pizza I thought?
于是乎这个本来只有13个回复的坟贴开始陆续被人挖坟,比如过了两个多月就有人问到,600刀买的披萨怎么样?
November 29, 2010, 10:58:22 AM
bitcoinex:Greetings from November 2010!
What’s is it eat pizza for $2600?
又过了三个多月,又有人问2600刀的披萨好吃吗?还有人问道,这披萨会有一天价值百万吗?
April 24, 2011, 02:33:19 AM
Littleshop:Someone could write a story about the $18,000 pizza!
很快*币特比**的价格突破1刀,披萨总价高达18000刀。
这期间Laszlo本人除了跟大家讨论挖矿外,也回应过披萨的问题:
August 04, 2010, 05:51:05 PM
Well I didn’t expect this to be so popular but I can’t really afford to keep doing it since I can’t generate thousands of coins a day anymore Smiley Thanks to everyone who bought me pizza already but I’m kind of holding off on doing any more of these for now.
大意是他自己也没想到搞了这么个大新闻,但他现在吃不起这种披萨了,因为现在挖矿变难了,他无法再每天挖出几千枚*币特比**了。
February 14, 2014, 02:17:19 PM
I mean people can say I’m stupid, but it was a great deal at the time. I don’t think anyone could have known it would take off like this.
大意是人们可能会说做了这笔交易的我是个笨蛋,但在当时谁也没意料到*币特比**会变得这么值钱。
February 14, 2014, 04:28:36 PM
The people I traded with didn’t know it was going to explode either, they just took a risk - spending their ’real’ money to buy some guy pizza in exchange for some internet Monopoly money.
Laszlo很赞赏第一批接受*币特比**交易的人,认为他们冒着风险,用”真金白银“去换这些虚拟货币。
February 14, 2014, 05:21:41 PM
I heard from one person who bought a house with their pizza bitcoins, indirectly, by trading it for cash first. I wish I could say I did the same, but the pizza didn’t appreciate the same way as the bitcoins
Laszlo说他听说过有人用披萨换来的*币特比**购买了房子,他也希望自己能这么做。
February 14, 2014, 09:52:18 PM
Other than a little bit of single digit change, I spent everything I mined. As you all know, the difficulty rises to adjust to hashing power, so eventually the mining wasn’t worth it for me.
Laszlo说他已经花光了所有挖到的*币特比**。现在*币特比**越来越难挖了,他觉得个人不值得再去挖矿了。

Laszlo在论坛的最后发言截至在2014年2月20日,不知道他现在怎么样了。根据他公开*币特比**钱包显示,他一共搞到过八万多枚*币特比**,但现在账面已经为零。但由于*币特比**的匿名性,所以无法得知Laszlo是否还有其他的*币特比**钱包。但根据他本人的说法,他已经没有多少*币特比**了。
可能有人会好奇,Laszlo是如何搞到这么多*币特比**的呢?
I generated my share and I spent it, it was just at a time when the value was lower, but so was the generation difficulty, and the block reward was 50. As far as I know I was the first to release a GPU miner.
他自己也解释了,当时*币特比**不值钱,所以挖的人少,因此难度也低。而且他们那个时候挖到一个区块的奖励是50个*币特比**。此外,据他所知,他自己是第一个用GPU挖矿的人。
这里我补充一下,*币特比**会根据挖矿者的总算力调整挖矿难度,使得无论挖矿的人有多少,*币特比**区块生成的时间控制在十五分钟左右。Laszlo作为最早的一批挖矿者,他们那个时候很容易挖到矿。
记录*币特比**交易的单元叫做区块,最开始没挖到一个区块会奖励矿工50个*币特比**。每挖出21万个区块后奖励会衰减一半,目前已经挖出了51万个区块,所以奖励衰减到了50/2/2=12.5*币特比**。
总结下就是Laszlo入行早,那时候挖矿容易而且奖励多,所以如他所说他一天就能挖到几千枚*币特比**。而且他最早意识到了GPU挖矿的效率远高于CPU,他自己表示他所有的*币特比**都是通过一块 nvidia 9800 GTX+显卡在Mac OS环境下挖的。

看来Laszlo并没有因为*币特比**而暴富。到这里,大家可能还会好奇另一位主角Jercos现在怎么样了。
https://en.bitcoin.it/wiki/Jercosen.bitcoin.it
根据*币特比**维基百科的说法,Jercos在交易时才18岁,算下来现在也才26岁。
有记者在五年后采访到了Jercos本人,那个时候10000枚*币特比**已经超过了1000万美元。
Q. What do you primarily use bitcoins for? Do you still control millions of dollars worth?
A. Bitcoin as a currency is meant to be spent. Those 10,000 BTC made it back into the economy fairly quickly, around the time they were worth some $400.
Bitcoin Address Lookup Checker and Alertsbitcoinwhoswho.com

Jercos表示他很快就把这些*币特比**花了,挣了400刀,回报率达到了10倍。

好魔幻的现实,跌宕起伏的剧情。本来我觉得这俩人应该早就成了超级富豪了,但也意外这两位心态都这么好。
