Wei Dai's announcement of Disperse/Collect version 1.0 on the Cypherpunks mailing list. This post explicitly references 'my own Crypto++ library,' confirming that Dai was not only a theorist but an active, prolific coder who built and shipped software. This context is essential for understanding why he later chose not to implement b-money.
Wei Dai's original announcement of b-money on the Cypherpunks mailing list. Notably, b-money was mentioned as a secondary item alongside PipeNet 1.1 — an anonymous routing protocol that was Dai's primary focus. The b-money proposal that would later inspire Bitcoin was introduced in a single sentence at the end of this post.
Wei Dai's reply to Adam Back on the Cypherpunks mailing list, discussing b-money's practical limitations. Dai acknowledged that 'b-money will at most be a niche currency/contract enforcement mechanism' and revealed a shift in his political views, stating 'I now tend to think that the government monopoly of force is a net benefit.'
In a comment on his Unenumerated blog, Nick Szabo asked for help implementing bit gold — the digital currency concept he had designed in 1998. No one publicly responded. Six months later, Satoshi Nakamoto published the Bitcoin whitepaper.
The first known tweet about Bitcoin. Hal Finney posted 'Running bitcoin' on January 10, 2009 (PST) / January 11, 2009 (UTC), the same day the Bitcoin v0.1 software was publicly released. He was the first person other than Satoshi to run Bitcoin.
The first person-to-person Bitcoin transaction in history. Satoshi Nakamoto sent 10 BTC to Hal Finney in Block 170, confirming that Bitcoin's peer-to-peer electronic cash system worked as designed.
Hal Finney's essay on LessWrong, written approximately two months after his ALS diagnosis in August 2009. Despite facing a terminal illness, Finney expressed hope and determination, dreaming of contributing to open-source software even from within an immobile body.
NewLibertyStandard published the first-ever exchange rate for Bitcoin: $1 = 1,309.03 BTC ($0.000764 per BTC). The rate was calculated based on the electricity cost required to mine Bitcoin — a rudimentary but historically significant first attempt to assign monetary value to Bitcoin.
Martti Malmi sold 5,050 BTC to NewLibertyStandard for $5.02 via PayPal — the first known exchange of Bitcoin for fiat currency. The transaction established a real-world price of approximately $0.001 per BTC.
NewLibertyStandard proposed adopting the Thai baht currency symbol (฿) as Bitcoin's official symbol and 'BTC' as the three-letter currency code. This proposal on BitcoinTalk established the currency notation still used today.
Laszlo Hanyecz paid 10,000 BTC for two Papa John's pizzas — the first purchase of a physical good with Bitcoin. The transaction, completed on May 22, 2010, is celebrated annually as 'Bitcoin Pizza Day.' At the time, 10,000 BTC was worth approximately $41.
Slashdot, one of the most influential technology news sites at the time, published an article about Bitcoin v0.3. The resulting 'Slashdot effect' caused a massive surge in downloads and new users, marking Bitcoin's first significant mainstream tech media exposure.
An integer overflow bug (CVE-2010-5139) was exploited to create 184,467,440,737.09551616 BTC in a single transaction in Block 74638. Satoshi Nakamoto published a fix within 5 hours, and the corrected chain overtook the invalid chain within 15 hours — the most serious crisis in Bitcoin's history.
Wei Dai's comments on the LessWrong 'Making money with Bitcoin?' thread. He clarified that he did not create Bitcoin but 'only described a similar idea more than a decade ago' and that Satoshi independently reinvented the concept. He revealed purchasing a Radeon 5870 GPU for mining after this thread, and warned that 'not many other cryptographers have analyzed its security.'
One of the first major print magazine articles about Bitcoin, published in Forbes. Andy Greenberg interviewed Gavin Andresen, who described Bitcoin as 'better gold than gold.' The article brought significant mainstream media attention and may have contributed to Satoshi's decision to withdraw from public communication.
Mike Hearn's private email correspondence with Satoshi Nakamoto, in which Satoshi stated he had 'moved on to other things' and that Bitcoin was 'in good hands with Gavin and everyone.'
Satoshi Nakamoto's final known private communications: on April 23, 2011, he told Mike Hearn 'I've moved on to other things. It's in good hands with Gavin and everyone.' Three days later, on April 26, he sent his last known email to Gavin Andresen, transferring the network alert key and writing 'I've moved on to other things and will probably be unavailable.'
Nick Szabo discusses why Bitcoin took so long to be invented, the similarities and differences between bit gold and Bitcoin, and why 'nearly everybody who heard the general idea thought it was a very bad idea.'
WikiLeaks announced it would accept Bitcoin donations, circumventing a financial blockade imposed by Bank of America, Visa, MasterCard, PayPal, and Western Union. Satoshi had warned against this six months earlier, saying it would bring unwanted government attention to the still-nascent network.
The Bitcoin Forum, originally set up by Martti Malmi at bitcoin.org/smf using Simple Machines Forum (SMF) software, migrated to the independent domain bitcointalk.org in August 2011. The migration was managed by forum administrator Theymos (Michael Marquardt) and preserved all existing posts, threads, and user accounts.
Renowned security researcher Dan Kaminsky attempted to find vulnerabilities in Bitcoin and failed. 'I came up with beautiful bugs. But every time I went after the code there was a line that addressed the problem.' He concluded: 'Either there's a team of people who worked on this, or this guy is a genius.'
Hal Finney's famous retrospective on his early involvement with Bitcoin, his interactions with Satoshi, and his battle with ALS. One of the most celebrated posts in Bitcoin history.
Bitcoin researcher Sergio Demian Lerner published 'The Well Deserved Fortune of Satoshi Nakamoto,' identifying a distinctive mining pattern (later named 'Patoshi') in Bitcoin's earliest blocks. The analysis linked approximately 22,000 blocks (~1.1 million BTC) to a single miner presumed to be Satoshi Nakamoto. Virtually none of these coins have ever been spent.
Wei Dai's comments on the LessWrong post 'Bitcoins are not digital greenbacks,' in which he argued that Bitcoin has 'failed with regard to its monetary policy' due to price volatility, and revealed that he never responded to Satoshi's 2008 email asking for comments — regretting that he 'could have dissuaded him (or them) from the fixed supply of money idea.'
Five months after his initial ExtraNonce analysis, Lerner discovered that Satoshi's nonce values had a highly non-random least significant byte (LSB) distribution — restricted to values [0..9] and [19..58], approximately 50 out of 256 possible values. This second fingerprint, independent of ExtraNonce, proved Satoshi used custom mining software with parallelized nonce space partitioning.
Wei Dai's reflections on Satoshi Nakamoto and on why b-money was never implemented, from a LessWrong Q&A thread. Dai stated that Satoshi 'didn't even read my article before reinventing the idea himself,' and later explained that b-money 'wasn't a complete practical design yet' and that he had 'grown somewhat disillusioned with cryptoanarchy' by the time he finished writing it up.
Mt. Gox, once the world's largest Bitcoin exchange handling approximately 70% of all Bitcoin transactions, filed for bankruptcy in Tokyo. CEO Mark Karpeles revealed that approximately 850,000 BTC (worth ~$450 million) had been lost. The collapse was the most significant crisis Bitcoin had faced since the 2010 value overflow incident.
Newsweek publishes 'The Face Behind Bitcoin,' identifying Dorian Prentice Satoshi Nakamoto, a 64-year-old Japanese-American man living in Temple City, California, as Bitcoin's creator.
A post from Satoshi's P2P Foundation account saying 'I am not Dorian Nakamoto' in response to Newsweek's article claiming to have found Bitcoin's creator. The authenticity of this post is debated.
Wei Dai's LessWrong post revealing that Satoshi Nakamoto emailed him personally in early 2009 announcing Bitcoin v0.1, but he ignored it because he 'was more interested in Less Wrong than Cypherpunks at that point.' He later started mining in 2011 after seeing a LW article, turning ~$300 into six figures.

Satoshi Nakamoto's P2P Foundation profile shows login activity in late 2016, years after the 'I am not Dorian Nakamoto' post in 2014, sparking renewed speculation about the account's security.
Mike Hearn publishes his private email correspondence with Satoshi Nakamoto, providing valuable insights into Satoshi's thinking about Bitcoin's technical future.
Seven Chinese government regulators jointly banned all ICOs and ordered domestic cryptocurrency exchanges to shut down. China had been the world's largest Bitcoin mining hub and trading market. Bitcoin's price dropped sharply, but miners relocated to other countries and trading shifted to decentralized platforms.
Ray Dillinger's retrospective on his role in Bitcoin's earliest days: reviewing the blockchain code, his division of labor with Hal Finney, and his reflections on Satoshi's integrity — 'He wasn't selling coins, he was giving them away for solving hashes.'

Blockchain tracking service Whale Alert published an independent analysis confirming Satoshi mined 1,125,150 BTC across 22,503 of the first 54,316 blocks. The report found Satoshi maintained approximately 60% hashrate using ~48 computers, deliberately throttling to protect the network rather than maximize profit.
Doncho Karaivanov analyzes 742 activity instances across Satoshi's posts, commits, and emails, combined with The Times headline evidence and British spelling conventions, to argue Satoshi was based in London.
CoinDesk published previously unpublished emails between Satoshi Nakamoto and Hal Finney, obtained from Hal's personal computer via his widow Fran Finney. The emails included Finney asking Satoshi about network scalability in November 2008, Satoshi personally notifying Finney of the v0.1 release on January 8, 2009, and a follow-up where Satoshi mentioned being unable to receive incoming connections.
Multiple blockchain analyses estimate that Satoshi Nakamoto mined approximately 1.1 million bitcoins in Bitcoin's earliest days, with none of these coins having ever been spent.
Craig Wright sued the pseudonymous operator of bitcoin.org (Cobra) over Bitcoin whitepaper copyright. Cobra refused to reveal his identity to defend himself, resulting in a default judgment on June 28, 2021. The court ordered bitcoin.org to remove the whitepaper.
After the London High Court ordered bitcoin.org to remove the Bitcoin whitepaper, Cobra responded on Twitter with a scathing critique of the legal system and a declaration that cryptographic rules are superior to court-enforced rules.
Reykjavik University researchers publish the first peer-reviewed academic study of the Patoshi pattern in PLOS ONE. The paper identifies two distinct nonce anomalies — the 'P anomaly' (extended Patoshi) and the 'Z anomaly' (zerononce) — and crucially finds that the P anomaly appears in ALL of the first 64 blocks mined, including Block 12 which was previously classified as non-Patoshi by ExtraNonce analysis.
In a detailed podcast interview, security researcher Dustin Trammell ('Druid') describes his experience as possibly the second node on the Bitcoin network. He recalls seeing only 'one other node' for 4-6 hours after first connecting, not realizing mining was disabled by default, and not starting to mine until 4-5 days later.
Bitcoin researcher Jameson Lopp demonstrates that Satoshi deliberately throttled mining capacity, earning only ~1.1 million BTC when full-capacity mining could have yielded ~2.19 million BTC. Lopp concludes: 'Anyone who claims that Satoshi was greedy simply hasn't done the math.'
SerHack published an analysis of a pre-release Bitcoin genesis block dated September 10, 2008 — discovered in source code Satoshi shared privately in November 2008. The test block had a completely different hash, trivially easy difficulty, and an initial block reward of 10,000 units. The September 10 date coincides with Lehman Brothers announcing $3.9 billion in losses.
FTX, the world's second-largest cryptocurrency exchange, filed for Chapter 11 bankruptcy. Founder Sam Bankman-Fried resigned as CEO. Approximately $8 billion in customer funds had been misappropriated. SBF was later convicted on all seven criminal counts and sentenced to 25 years in prison.
Bitcoins mined in the earliest weeks of Bitcoin's existence in January 2009 are moved for the first time, sparking intense speculation about whether Satoshi Nakamoto is spending coins.

Forensicxs published a comprehensive line-by-line walkthrough of Bitcoin v0.1's 31,794 lines of source code — one of the most detailed public analyses of Satoshi Nakamoto's original codebase. The analysis covered all 31 files across cryptography, blockchain operations, networking, wallet management, and the GUI.
Pete Rizzo investigates the unexplained ~5-day, 8-hour gap between the Genesis Block (January 3, 2009) and Block 1 (January 9, 2009), framing it as one of Bitcoin's enduring unsolved mysteries.
Early Bitcoin developer Jeff Garzik released a series of videos detailing his time working with Satoshi Nakamoto, describing the creator as a self-taught, solitary genius who never revealed any personal information.
In a CoinGeek interview, Mike Hearn offers rare reflections on Satoshi Nakamoto's personality, describing him as someone who enjoyed experimenting and discussing possibilities but grew frustrated when evangelical personalities arrived in the community.
In an April 2025 interview, P2P Foundation founder Michel Bauwens recalled that Satoshi emailed him several times, offered him a few bitcoins, and explained why he was publishing the white paper on the P2P Foundation site. Bauwens also gave a mature retrospective on Bitcoin: he remained skeptical of its energy costs, but saw it as the first globally scalable, socially sovereign currency not issued by a firm or state.
Blockstream CEO Adam Back stated that Bitcoin faces no quantum computing threat for roughly 20–40 years, pointing to NIST-standardized post-quantum signatures like SLH-DSA that Bitcoin can adopt well before any threat materializes.
