Satoshi Nakamoto

Satoshi Nakamoto

Satoshi Nakamoto is the name used by the unknown person(s) who designed bitcoin and created its original reference implementation. [1] As part of the implementation, they also devised the very first blockchain database. In the process they were the very first to solve the double-spending problem for digital currency. They were active in the development of bitcoin up until December 2010.

Nakamoto has claimed to be a man living in Japan, born on five April 1975. [Two] However, speculation about the true identity of Nakamoto has mostly focused on a number of cryptography and computer science experts of non-Japanese descent, living in the United States and Europe. [Trio]

As of twenty four May two thousand seventeen [update] , Nakamoto is believed to own up to harshly one million bitcoins, [Four] with a value estimated at approximately $Four.7 billion USD as of August two thousand seventeen [update] .

In October 2008, Nakamoto published a paper [Five] [6] on The Cryptography Mailing list at metzdowd.com [7] describing the bitcoin digital currency. It was titled Bitcoin: A Peer-to-Peer Electronic Cash System. In January 2009, Nakamoto released the very first bitcoin software that launched the network and the very first units of the bitcoin cryptocurrency, called bitcoins. [8] [9] Satoshi Nakamoto released the Version 0.1 of Bitcoin software on Sourceforge on nine January 2009.

Nakamoto claimed that work on the writing of the code began in 2007. [Ten] The inventor of bitcoin knew that due to its nature the core design would have to be able to support a broad range of transaction types. The implemented solution enabled specialised codes and data fields from the begin through the use of a predicative script. [11]

Nakamoto created a website with the domain name bitcoin.org and continued to collaborate with other developers on the bitcoin software until mid-2010. Around this time, he passed over control of the source code repository and network alert key to Gavin Andresen, [12] transferred several related domains to various prominent members of the bitcoin community, and stopped his involvement in the project. Until shortly before his absence and handover, Nakamoto made all modifications to the source code himself.

The inventor left a text message in the very first mined block which reads ‘The Times three January two thousand nine Chancellor on brink of 2nd bailout for banks’. The text refers to a headline in The Times published on three January 2009. It is a strong indication that the very first block was mined no earlier than this date. [13] The genesis block has a timestamp of Legal:15:05 GMT on three January 2009. This block is unlike all other blocks in that it doesn’t have a previous block to reference. [13] This required the use of custom-built code to mine it. Timestamps for subsequent blocks indicate that Nakamoto did not attempt to mine all the early blocks solely for himself. [13]

As the foot, predominant early miner the inventor was awarded bitcoin at genesis and for ten days afterwards. [14] Except for test transactions these remain unspent since mid January 2009. [14] The public bitcoin transaction log shows that Nakamoto’s known addresses contain harshly one million bitcoin. As of eighteen August 2017, this is worth over $Four,053,500,000. [15] [16] Due to the hardfork in which Bitcoin Cash was made, creating one Bitcoin Cash for every bitcoin in circulation, he also wields harshly one million Bitcoin Cash, worth about $675,510,000. [17] [16]

Nakamoto did not disclose any individual information when discussing technical matters. [Three] He provided some commentary on banking and fractional reserve lending. On his P2P Foundation profile as of 2012, Nakamoto claimed to be a 37-year-old masculine who lived in Japan, [Legitimate] but some speculated he was unlikely to be Japanese due to his use of ideal English and his bitcoin software not being documented or labelled in Japanese. [Three]

Occasional British English spelling and terminology (such as the phrase “bloody hard”) in both source code comments and forum postings led to speculation that Nakamoto, or at least one individual in the consortium claiming to be him, was of Commonwealth origin. [Five] [Three] [Nineteen]

Stefan Thomas, a Swiss coder and active community member, graphed the time stamps for each of Nakamoto’s bitcoin forum posts (more than 500); the resulting chart displayed a steep decline to almost no posts inbetween the hours of five a.m. and eleven a.m. Greenwich Mean Time. Because this pattern held true even on Saturdays and Sundays, it suggested that Nakamoto was asleep at this time. [Trio] If Nakamoto is a single individual with conventional sleeping habits, it suggests he resided in a region using the UTC−05:00 or UTC−06:00 time offset. This includes the parts of North America that fall within the Eastern Time Zone and Central Time Zone, as well as parts of Central America, the Caribbean and South America.

Satoshi’s initial email to Dai is dated twenty two August two thousand eight ; the metadata for this PDF ( pdftk bitcoin.pdf dump_data ) yields as the CreationDate the value 20081003134958-07’00’ – this implies three October two thousand eight or a bit over a month later, which is consistent with the local date mentioned in the Cypherpunk mailing list email. This is an earlier draft than the final draft on bitcoin.org , which is dated 20090324113315-06’00’ or twenty four March 2009; the timezone differs: -7 vs -6. [20]

Gavin Andresen has said of Nakamoto’s code “He was a brilliant coder, but it was quirky”. [21]

Possible identities Edit

There is still doubt about the real identity of Satoshi Nakamoto. [22]

Nick Szabo Edit

In December 2013, a blogger named Skye Grey linked Nick Szabo to the bitcoin whitepaper using a stylometric analysis. [23] [24] [25] Szabo is a decentralized currency enthusiast and published a paper on “bit gold”, which is considered a precursor to bitcoin. [24] [25] He is known to have been interested in using pseudonyms in the 1990s. [26] In a May two thousand eleven article, Szabo stated about the bitcoin creator: “Myself, Wei Dai, and Hal Finney were the only people I know of who liked the idea (or in Dai’s case his related idea) enough to pursue it to any significant extent until Nakamoto (assuming Nakamoto is not indeed Finney or Dai).” [27]

Detailed research by financial author Dominic Frisby provides much circumstantial evidence but, as he admits, no proof that Satoshi is Szabo. [28] Speaking on RT’s The Keiser Report, he said “I’ve concluded there is only one person in the entire world that has the sheer breadth but also the specificity of skill and it is this chap . “. [29] But Szabo has denied being Satoshi. In a July two thousand fourteen email to Frisby, he said: ‘Thanks for letting me know. I’m afraid you got it wrong doxing me as Satoshi, but I’m used to it’. [30] Nathaniel Popper wrote in the Fresh York Times that “the most persuading evidence pointed to a reclusive American man of Hungarian descent named Nick Szabo.” [31]

Dorian Nakamoto Edit

In a high-profile six March 2014, article in the magazine Newsweek, [32] journalist Leah McGrath Goodman identified Dorian Prentice Satoshi Nakamoto, a Japanese American man living in California, whose birth name is Satoshi Nakamoto, [32] [33] [34] as the Nakamoto in question. Besides his name, Goodman pointed to a number of facts that circumstantially suggested he was the bitcoin inventor. [32] Trained as a physicist, Nakamoto worked as a systems engineer on classified defense projects and computer engineer for technology and financial information services companies. Nakamoto was laid off twice in the early 1990s and turned libertarian, according to his daughter, and encouraged her to begin her own business and “not under the government’s thumb.” In the article’s seemingly fattest lump of evidence, Goodman wrote that when she asked him about bitcoin during a brief in-person interview, Nakamoto seemed to confirm his identity as the bitcoin founder by stating: “I am no longer involved in that and I cannot discuss it. It’s been turned over to other people. They are in charge of it now. I no longer have any connection.” [32] [35] The article’s publication led to a flurry of media interest, including reporters camping out near Dorian Nakamoto’s house and shortly pursuing him by car when he drove to an interview. [36] However, during the subsequent full-length interview, Dorian Nakamoto denied all connection to bitcoin, telling he had never heard of the currency before, and that he had misinterpreted Goodman’s question as being about his previous work for military contractors, much of which was classified. [37] In a reddit “ask-me-anything” interview, he claimed he’d misinterpreted Goodman’s question as being related to his work for Citibank. [38] Later that day, the pseudonymous Nakamoto’s P2P Foundation account posted its very first message in five years, stating: “I am not Dorian Nakamoto.” [39] [40]

Hal Finney Edit

Hal Finney (Four May one thousand nine hundred fifty six – twenty eight August 2014) was a pre-bitcoin cryptographic pioneer and the very first person (other than Satoshi himself) to use the software, file bug reports, and make improvements. [41] He also lived a few blocks from Dorian Nakamoto’s family home, according to Forbes journalist Andy Greenberg. [42] Greenberg asked the writing analysis consultancy Juola & Associates to compare a sample of Finney’s writing to Satoshi Nakamoto’s, and they found that it was the closest resemblance they had yet come across (including the candidates suggested by Newsweek, Quick Company, The Fresh Yorker, Ted Nelson and Skye Grey). [42] Greenberg theorized that Finney may have been a ghostwriter on behalf of Nakamoto, or that he simply used his neighbor Dorian’s identity as a “drop” or “patsy whose private information is used to hide online exploits”. However, after meeting Finney, observing the emails inbetween him and Satoshi, his bitcoin wallet’s history including the very very first bitcoin transaction (from Satoshi to him, which he left behind to pay back) and hearing his denial, Greenberg concluded Finney was telling the truth. Juola & Associates also found that Satoshi’s emails to Finney more closely resemble Satoshi’s other writings than Finney’s do. Finney’s fellow extropian and sometimes co-blogger Robin Hanson assigned a subjective probability of “at least” 15% that “Hal was more involved than he’s said”, before further evidence suggested that was not the case. [43]

Craig Steven Wright Edit

On eight December 2015, Wired wrote that Craig Steven Wright, an Australian former academic, “either invented bitcoin or is a brilliant hoaxer who very badly wants us to believe he did”. [44] Craig Wright took down his Twitter account and neither he nor his ex-wife responded to press inquiries. The same day, Gizmodo published a story with evidence obtained by a hacker who supposedly broke into Wright’s email accounts, claiming that Satoshi Nakamoto was a joint pseudonym for Craig Steven Wright and computer forensics analyst David Kleiman, who died in 2013. [45] A number of prominent bitcoin promoters remained unconvinced by the reports. [46] Subsequent reports also raised the possibility that the evidence provided was an elaborate hoax, [47] [48] which Wired acknowledged “cast doubt” on their suggestion that Wright was Nakamoto. [49]

On nine December, only hours after Wired claimed Wright was Nakamoto, Wright’s home in Gordon, Fresh South Wales was raided by at least ten police officers. His business premises in Ryde, Fresh South Wales were also searched by police. The Australian Federal Police stated they conducted searches to assist the Australian Taxation Office and that “This matter is unrelated to latest media reporting regarding the digital currency bitcoin.” [50] According to a document released by Gizmodo alleged to be a transcript of a meeting inbetween Wright and the ATO, he had been involved in a taxation dispute with them for several years. [45]

On two May 2016, Craig Wright posted on his blog publicly claiming to be Satoshi Nakamoto. In articles released on the same day, journalists from the Big black cock and The Economist stated that they spotted Wright signing a message using the private key associated with the very first bitcoin transaction. [51] [52] Wright’s claim was supported by Jon Matonis (former director of the Bitcoin Foundation) and bitcoin developer Gavin Andresen, both of whom met Wright and witnessed a similar signing demonstration. [53]

However, bitcoin developer Peter Todd said that Wright’s blog post, which appeared to contain cryptographic proof, actually contained nothing of the sort. [54] The Bitcoin Core project released a statement on Twitter telling “There is presently no publicly available cryptographic proof that anyone in particular is Bitcoin’s creator.” [55] [56] Bitcoin developer Jeff Garzik agreed that evidence publicly provided by Wright does not prove anything, and security researcher Dan Kaminsky concluded Wright’s claim was “intentional scammery”. [57] [58]

On four May 2016, Wright made another post on his blog promising to publish “a series of lumps that will lay the foundations for this extreme claim”. [59] [60] But the following day, he deleted all his blog posts and substituted them with a notice entitled “I’m Sorry”, which read in part:

I believed that I could put the years of anonymity and hiding behind me. But, as the events of this week unfolded and I ready to publish the proof of access to the earliest keys, I broke. I do not have the courage. I cannot. [61] [62]

In June 2016, the London Review of Books published a 35,000 word article by Andrew O’Hagan about the events, based on discussions with Wright and many of the other people involved. [63] [64] It also exposes that the Canadian company nTrust was behind Wright’s claim made in May 2016.

Other speculations Edit

In a two thousand eleven article in The Fresh Yorker, Joshua Davis claimed to have narrowed down the identity of Nakamoto to a number of possible individuals, including the Finnish economic sociologist Dr. Vili Lehdonvirta and Irish student Michael Clear, then a graduate student in cryptography at Trinity College Dublin. [65] Clear strongly denied he was Nakamoto, [66] as did Lehdonvirta. [67] In October 2011, writing for Prompt Company, investigative journalist Adam Penenberg cited circumstantial evidence suggesting Neal King, Vladimir Oksman and Charles Bry could be Nakamoto. [68] They jointly filed a patent application that contained the phrase “computationally impractical to switch sides” in 2008, which was also used in the bitcoin white paper by Nakamoto. [Sixty nine] The domain name bitcoin.org was registered three days after the patent was filed. All three studs denied being Nakamoto when contacted by Penenberg. [68]

In May 2013, Ted Nelson speculated that Nakamoto is truly Japanese mathematician Shinichi Mochizuki. [70] Later, an article was published in The Age newspaper that claimed that Mochizuki denied these speculations, but without attributing a source for the denial. [71] A two thousand thirteen article, [72] in Vice listed Gavin Andresen, Jed McCaleb, or a government agency as possible candidates to be Nakamoto. Dustin D. Trammell, a Texas-based security researcher, was suggested as Nakamoto, but he publicly denied it. [73] In 2013, two Israeli mathematicians, Dorit Ron and Adi Shamir, published a paper claiming a link inbetween Nakamoto and Ross William Ulbricht. The two based their suspicion on an analysis of the network of bitcoin transactions, [74] but later retracted their claim. [75]

Some considered Nakamoto might be a team of people; Dan Kaminsky, a security researcher who read the bitcoin code, [76] said that Nakamoto could either be a “team of people” or a “genius”; [Nineteen] Laszlo Hanyecz, a former bitcoin core developer who had emailed Nakamoto, had the feeling the code was too well designed for one person.
