中本聰?shù)恼嫔碚业搅??原來不是日本?

比特幣之所以傳奇,一個(gè)重要原因就在于我們永遠(yuǎn)也無法真正得知誰才是這種著名加密貨幣的創(chuàng)造者。

《比特幣白皮書:一種點(diǎn)對點(diǎn)的電子現(xiàn)金系統(tǒng)》(Bitcoin: A Peer-to-Peer Cash System)一文在互聯(lián)網(wǎng)橫空出世,距今已有十年時(shí)間。寫出這篇論文的天才所描繪的數(shù)字貨幣,如今的價(jià)值已經(jīng)超過了1,000億美元,但他并未透露自己的身份,只留下了中本聰?shù)幕?/font>

如今的媒體每每描繪中本聰,總是離不開“神秘”這個(gè)形容詞。比特幣之所以傳奇,一個(gè)重要原因就在于我們永遠(yuǎn)也無法真正得知誰才是這種著名加密貨幣的創(chuàng)造者。雖然如此,這份白皮書的作者究竟是誰,如今卻已有充足的證據(jù)。

如果你認(rèn)同“奧卡姆的剃刀”(Occam’s razor)這個(gè)哲學(xué)原理,即最簡單的解決方案往往就是正確的那個(gè),那么中本聰?shù)纳矸菥蛶缀醪淮嬖谝蓡柫恕辽僭诠P者看來如此——他是一個(gè)50歲左右的美國人,名為尼克·紹博。

筆者第一次聽說這個(gè)人,是在六年前報(bào)道科技網(wǎng)站Gigaom的比特幣大會(huì)時(shí)。然后就像現(xiàn)在,加密貨幣的圈內(nèi)人士不愿意公開表示紹博是中本聰,但是在私下的交談中,好幾個(gè)人向筆者透露:他們認(rèn)為是紹博創(chuàng)造了比特幣。

許多外部證據(jù)都支持這一結(jié)論。權(quán)威記錄比特幣早期歷程的作品《數(shù)字黃金》(Digital Gold)的作者納撒尼爾·波普爾描述了紹博早期的文章如何描繪了比特幣的架構(gòu),在中本聰?shù)谋忍貛虐灼l(fā)表后不久,他如何邀請其他人幫助他“編碼一個(gè)”。

他的個(gè)人經(jīng)歷也很符合。與其他疑似中本聰?shù)娜耍ê芸炀蜁?huì)討論到他們)不同,紹博的專業(yè)背景很對口。他是一位計(jì)算機(jī)專家,一位熟練的密碼員,據(jù)說也是名法學(xué)學(xué)者。他自由主義的世界觀也與中本聰一致,后者在比特幣的第一個(gè)區(qū)塊鏈中編碼了一條譴責(zé)銀行緊急援助的消息。我在今年紐約的金融會(huì)議上見到紹博時(shí),他正大談隱私問題,以及對于不需要信任第三方的金融系統(tǒng)的需求——這是中本聰白皮書中的核心觀點(diǎn)。

所有這一切都表明中本聰就是紹博。不過至少在我看來,讓這一結(jié)論擺脫嚴(yán)重質(zhì)疑的,是2014年的一次語言分析。這次語言分析由英國阿斯頓大學(xué)(Aston University)司法語言學(xué)中心(Centre for Forensic Linguistics)展開,他們將中本聰?shù)恼撐呐c12位被認(rèn)為可能是比特幣創(chuàng)造者的作品進(jìn)行了對比。結(jié)論呢?“語言學(xué)上看,紹博的作品與比特幣白皮書的相同點(diǎn)多得不可思議,其他候選人遠(yuǎn)不能及。”

依據(jù)奧卡姆的剃刀理論,中本聰就是紹博。同理,其他中本聰候選人的情況要復(fù)雜得多,因此可能性就大為降低。

網(wǎng)站Breaker于上周發(fā)布了一篇文章,題為“瘋狂尋找中本聰”,這是一位記者試圖尋找比特幣創(chuàng)始人的經(jīng)歷,很有參考價(jià)值。隨著線索逐漸明了,其他中本聰?shù)暮蜻x人都不符合條件。其中包括克雷格·賴特,他是唯一自稱為中本聰?shù)娜耍悄切┲С炙f法的技術(shù)陳述已經(jīng)被證明為假,加密貨幣領(lǐng)域的許多人都斥責(zé)他為騙子,其中還包括維塔利克·布特林(以太坊創(chuàng)始人)。

這讓紹博成了唯一可信的中本聰人選。(證據(jù)是否無可爭議?并不。我相信他是中本聰嗎?絕對相信。)不過,某個(gè)反對意見阻止了該問題蓋棺定論:紹博屢次否認(rèn)自己是比特幣創(chuàng)始人。他在2015年給Popper的文章中寫道:“所有這些推論讓我受寵若驚,但是錯(cuò)了——我不是中本聰?!?/font>

為什么要否認(rèn)?原因有二。首先,“中本聰”有充分的理由不暴露身份。與中本聰綁定的區(qū)塊鏈錢包里有超過100萬個(gè)比特幣,價(jià)值數(shù)十億美元。暴露自己中本聰?shù)纳矸?,?huì)立刻引來政府、稅務(wù)部門和一系列罪犯的關(guān)注,保持匿名會(huì)安全得多。同樣,紹博很重視隱私(有些人將其稱為隱士),可是一旦承認(rèn)自己是中本聰,他就會(huì)立刻變成被媒體和粉絲包圍的名人。

中本聰保持匿名的第二個(gè)理由更加微妙,但卻十分重要。他的身份一旦暴露,就會(huì)降低比特幣誕生的傳奇性。像許多宗教一樣,比特幣的吸引力有一部分正是來自它的神秘。比特幣的信徒和記者都喜歡中本聰?shù)纳裨挘屗蹈駷橐粋€(gè)美國人發(fā)表論文的平凡故事,會(huì)讓整件事情樂趣大減。

所以,即使有可靠證據(jù)表明中本聰就是尼克·紹博,輿論依舊認(rèn)為比特幣的誕生是個(gè)謎。所有人都更喜歡這種論調(diào)。不過至少在比特幣誕生十周年的這一天,讓我們?yōu)榱诉@一優(yōu)秀的加密貨幣和出色的工作而向紹博表示祝賀吧。(財(cái)富中文網(wǎng))

It’s 10 years to the day since a paper titled “Bitcoin: A Peer-to-Peer Cash System” first turned up on the Internet. The genius who wrote the paper, which describes a digital currency that is now worth over $100 billion, did not identify himself but instead used the pseudonym Satoshi Nakamoto.

The press today rarely describes Nakamoto without using the word “mysterious,” and it’s a mainstay of Bitcoin lore that we’ll never really know who created the famous cryptocurrency. Nonetheless, the evidence is overwhelming about who wrote the white paper.

If you subscribe to the philosophy principle known as Occam’s razor, which holds that the simplest solution tends to be the correct one, there’s little doubt—in my mind, at least—as to Nakamoto’s identity: He is a 50-something American named Nick Szabo.

I first heard of Szabo six years ago covering Bitcoin conferences for the tech site Gigaom. Then, as now, crypto insiders are reluctant to publicly state that Szabo is Satoshi but, in private conversations, several confided to me they think Szabo created Bitcoin.

There’s also plenty of external evidence to support this. Nathaniel Popper, whose book Digital Gold provides the canonical account of Bitcoin’s beginnings, has described how Szabo’s earlier writing described the architecture of Bitcoin, and how he asked others to help him “code one up” shortly before the Nakamoto white paper appeared.

There’s also the matter of biography. Unlike several other Satoshi suspects (more on that in a minute), Szabo’s background fits. He’s a computer savant and an accomplished cryptographer, and is reportedly a legal scholar as well. His libertarian worldview is also consistent with Satoshi, who encoded a message in the first block on Bitcoin’s blockchain decrying bank bailouts. When I saw Szabo appear at a financial conference in New York this year, he spoke primarily of privacy and the need for a financial system that didn’t require trusting a third party—central precepts of the Satoshi white paper.

All of this points to Satoshi being Szabo. But what pushes the conclusion beyond serious doubt, in my mind at least, is a 2014 linguistic analysis. That analysis, performed by the Aston University Centre for Forensic Linguistics in the UK, compared the writing style in the Satoshi paper to 12 people identified as possible creators of Bitcoin. The conclusion? “The number of linguistic similarities between Szabo’s writing and the Bitcoin whitepaper is uncanny, none of the other possible authors were anywhere near as good of a match.”

On the basis of the Occam’s Razor principle, Satoshi is Szabo. By the same token, the case for other Satoshi suspects is far more convoluted and therefore far less probable.

The website Breaker last week published “Desperately Seeking Satoshi,” a helpful history of journalists’ attempts to identify Bitcoin’s creator. As the recap makes clear, none of the other candidates come close to fitting the bill. This includes Craig Wright, who is the only one to claim he is Satoshi, but whose technical claims to support his case have proven false, and who has been reviled as a liar by many in the crypto community, including Vitalik Buterin.

This leaves Szabo as the only serious candidate to be Satoshi. (Is the proof indisputable? No. Am I convinced? Absolutely.) There is, though, one serious objection to closing the case: Szabo has repeatedly denied he is Bitcoin’s creator. “All this speculation is flattering, but wrong—I am not Satoshi,” Szabo wrote to Popper in 2015.

What to make of the denial? Two points. First, “Satoshi” has very good reasons not to identify himself. Namely, wallets on the blockchain tied to Satoshi contain more than 1 million Bitcoins, which is a fortune worth billions of dollars. Revealing himself as Satoshi would instantly invite the scrutiny of governments, tax agents and a hoard of criminals—maintaining a mask of anonymity is the much safer bet. Likewise, for a person like Szabo who values privacy (several accounts describe him as a recluse), claiming the mantle of Satoshi would transform him into a celebrity besieged by media and fanboys.

The second reason for Satoshi to preserve anonymity is more subtle but also important. Namely, it would undercut the marvelous origin story of Bitcoin. Like many religions, Bitcoin’s appeal is in part tied to its mystery. Bitcoin believers and journalists alike love the Satoshi Nakamoto myth, and reducing it to a more pedestrian story of an American who published a paper would make the whole thing less fun.

So even though there is persuasive evidence that Satoshi Nakamoto is Nick Szabo, the consensus remains that Bitcoin’s creation is a mystery. Everyone likes it better than way. But let’s take one day at least, on this tenth anniversary of Bitcoin, to congratulate Szabo on his marvelous cryptocurrency and a job well done.
