Satoshi Nakamoto

On August 20, 2008 Satoshi emailed Adam Back a link to a draft titled "Electronic Cash Without a Trusted Third Party." Its title and abstract survive in two emails. The PDF does not.

Gwern lists where he looked for the draft Satoshi linked in August 2008: the file host, the Internet Archive, Google, BitcoinTalk, SVN. Dai, Back and Maxwell had no copy; Finney never replied.

By 2008 Microsoft's free compiler wanted a Passport sign-in. Satoshi used the 1998 Visual C++ 6.0 and free MinGW, signed up for services under his pseudonym, and designed a system without accounts.

Satoshi's code had a COIN and a CENT and nothing smaller with a name. Bitcoin's smallest unit, the satoshi, was named by users on BitcoinTalk two months after his last post.

A remailer gave up a name to a warrant, Napster's index fell to an injunction, e-gold pleaded guilty and the Liberty Dollar was raided. In November 2008 Satoshi named the pattern.

Satoshi thanks Hal Finney, who had called the client's code an impressive job and "some powerful machinery" after another user called it a mess.

Satoshi answers a worry about buffer overflow attacks on the wallet: sending to an IP address is disabled by default, and the code is all STL, with almost no buffers.

In 2008 Satoshi wrote that only coin creators would eventually need to run nodes. Mining did leave ordinary computers; nodes did not. Who runs the nodes at 25,489 reachable addresses, and why, unpaid.

On October 3, 2026, 12,524 of the 25,501 Bitcoin addresses a crawler could reach were Tor onions. What the count measures, how it grew from Satoshi's 2009 Tor proxy support, and why nodes hide IPs.

Satoshi sized the 21 million cap so amounts would land between 0.01 and 1000. The cent ran through his code, his fees and more than two years of his writing. The yen does not appear even once.

Four exchanges opened between October 2009 and July 2010, none of them Satoshi's: NewLibertyStandard, Malmi's bitcoinexchange.com, Bitcoin Market and Mt. Gox. Satoshi advised from the sidelines.

On August 20, 2008 Satoshi called his C++ code nearly finished. Which precursors were in front of him by then? The earliest record for Hashcash, b-money, MicroMint, Bit Gold, DigiCash and RPOW.

In August 2010 a forum user asked whether Satoshi could withstand torture for Bitcoin's alert key. What the key could do, whose hands its copies reached, and how it left the network by 2018.

Asked in April 2013 how a decentralized currency came to have a chief scientist, Gavin Andresen answers with the Bitcoin Faucet, his code, and Satoshi swapping his own email address for Andresen's.

How a 1992 Oakland meeting became the Cypherpunks mailing list: the name, the remailers, the Clipper fight, the 1997 split, and the Hashcash and b-money posts the Bitcoin whitepaper later cited.

Neil McAllister's InfoWorld roundup gave Bitcoin four paragraphs on May 24, 2010, naming Satoshi and the word "cryptocurrency." Downloads rose for three days, then fell back.

Craig Wright's May 2, 2016 blog post, published the day he publicly claimed to be Satoshi, walking through an OpenSSL verification of a signature he presented as proof.

Craig Wright's May 3, 2016 blog post, the day after his public claim to be Satoshi, promising a series of posts and a transfer of bitcoin from an early block as proof.

Gavin Andresen's blog post of May 2, 2016, stating that he believed Craig Wright was Satoshi after a private signing session in London, with the note he added in February 2023.

American Bitcoin infrastructure engineer. Built Statoshi node telemetry (2014), was SWATted at his home in 2017, joined Casa (2018), and wrote "Who Controls Bitcoin Core?" (2018).

Satoshi and Malmi spent 2009 to 2010 correcting the bitcoin.org FAQ word by word, and readers still wrote to Satoshi when something went wrong. None of that wording survives on bitcoin.org today.

The bitcoin.org FAQ: Bitcoin's peer-to-peer design, coin generation, why mining margins shrink as value rises, and wallet and transaction basics. Drafted by Malmi, maintained by both him and Satoshi.

Hal Finney's full BitcoinTalk post recounting his early involvement with Bitcoin, his correspondence with Satoshi, and his ALS diagnosis.

Ray Dillinger on his November 2008 review of Bitcoin's block chain code with Hal Finney, why its lack of any Trusted role convinced him Satoshi wasn't scamming, and the ICO scams that followed.

Ray Dillinger's full 2018 interview for the Bitcoin whitepaper's 10th anniversary: his 2008 code review, the floating-point discovery, and his views on deflation and mining centralization.

Proof of work vs proof of stake, scored axis by axis with dated numbers: market cap, track record, energy, attack cost, decentralization, speed and new-chain adoption, with DPoS and PoA beside them.

CoinMarketCap recorded Ethereum's market cap at roughly 85% of Bitcoin's on June 12, 2017 — the closest 'the flippening' ever came to happening, before both fell back.

The only record of Satoshi's gender is one field on a profile that has never been confirmed, yet Satoshi is still called 'he.' Every named candidate is a man, and it all traces to a male pen name.

Word-count and interval statistics for all 164 of Satoshi's SVN commits (r15-r202), plus diff-size stats for 158: after his 75-day silence, Satoshi's messages got shorter, not longer.

Part 2 of 5. Thousands of computers end up agreeing on the exact same record by checking each other's work and chaining every page to the one before it.

Part 4 of 5. A sent payment sits in a waiting room each node keeps on its own before a miner seats it in a block — and even then, it only gets safer with time.

Part 3 of 5. New bitcoins exist because computers race to win a lottery-style puzzle, and the prize is the right to add the next page.

Part 1 of the beginner guide. A bitcoin is not a coin sitting in an account — it behaves more like a receipt, unlocked by a key only you hold.

Part 5 of the beginner guide. Two simple rules — everyone checks the rules, and the chain with the most work wins — are what keep a system with no boss honest.

Wei Dai called Bitcoin's fixed supply a failure in 2013. His own 1998 b-money design needed the same real-world value figure Satoshi said software has no way to know.

A curated way in: questions about Satoshi Nakamoto and Bitcoin history, each pointing to the page that answers it in full.

The only place Satoshi named a country for himself was one unverifiable profile. Language, timestamps, and the one actually Japanese candidate all read against that claim — and against each other.

Institutions built a $300B stake; governments turned seized coins into reserves. Two Nobel economists, asked years later, still weren't persuaded. What actually changed, checked against the record.

Satoshi's standalone bitcoin.org explanation of the Byzantine Generals problem, using a proof-of-work chain to make the generals agree on a plan.

James Donald tied the issue he pressed Satoshi on to the 1982 Byzantine Generals Problem. Satoshi said Bitcoin solved it in a network anyone could join, and explained it with a king's wi-fi password.

Doubters called it unscalable in 2008. A famed hacker failed to break the code. A judge, a dictionary, and a Nobel nominator weighed in. What others said about Satoshi, read as one record.

Eight pages posted to a mailing list on October 31, 2008 — a report on a working system that had been 18 months in the making. It met silence first, then doubts about scale.

A source-level map of Bitcoin v0.1: the byte boundaries for transaction, block, and signature hashes, and the reuse of one serializer across network and disk paths.

Five AI models were asked the same question and independently picked the same coin. Fact-checking their reasons: structural claims held up, confident superlatives mostly did not.

AnonymousSpeech.com, the anonymous intermediary behind bitcoin.org: its pitch of protection under Japanese law, a mail relay on a Malaysian IP address, and an operator trail that ends in silence.

Bitcoin's first price was a production-cost estimate. Satoshi predicted in 2010 that market price would come to dictate production cost — not the reverse. The arc from 2009 to modern models.

Satoshi's ~1.1M BTC sit still while companies, ETFs, and nation-states build stacks of their own. A sourced map of who holds the 21 million — and why the biggest whales still have no names.

The first person to answer the Bitcoin whitepaper, James Donald was also the only other person known to use a rare word of Satoshi's, making him Benjamin Wallace's top lead. The evidence, weighed.

A former SpaceX intern named him in a viral 2017 blog post, citing his command of both C++ and economics and an idiom he shares with Satoshi. The evidence for Elon Musk as Satoshi, weighed.

His legal name was, literally, Satoshi Nakamoto — and a 2014 Newsweek cover story named him. The evidence, weighed.

The only candidate who claimed the identity himself — declared in coordinated BBC and Economist interviews in May 2016, cryptographic proof in hand. The evidence, weighed.

He wrote E4M, then built a criminal empire. The case Evan Ratliff, author of The Mastermind, set out in 2019 for Paul Le Roux as Satoshi, weighed.

The whitepaper's title names a payment system; section 6's gold is an analogy for issuance. Bitcoin is scarce like gold and spends like cash, and its scarcity later earned it the name digital gold.

Weighing the 'Blockstream controls Bitcoin' charge against the documentary record: where it comes from, and how each link in the chain holds up.

When correspondents wished Satoshi merry Christmas, predicted $10M per coin, or hoped he was well, his replies went straight to the technical point and ignored the rest. Five patterns, examined.

Hayek's 1976 case for competing currencies, the Extropians' imaginary 'Hayeks' currency of 1995, and Bitcoin, money no state issues: one line of thought, linked by ideas rather than proven influence.

Attorney James A. Murphy filed a 2025 FOIA suit seeking DHS files on Agent Rana Saoud's 2019 claim that an agent went to interview a man he believed was Satoshi and found three more people involved.

Finding Satoshi (Tooley / Miele, April 2026) names Hal Finney and Len Sassaman as Bitcoin co-creators: Finney coded, Sassaman wrote the paper. Lopp and Back dispute it.

An anonymous plaintiff sues 39,069 dormant Bitcoin addresses holding ~3.8M BTC under New York's lost-property statute (March 2026). Galaxy Digital ties 21,923 of them to the Patoshi pattern.

Satoshi's difficulty retarget has an off-by-one: it measures 2,015 blocks instead of 2,016. A hashrate majority can exploit it via timestamp manipulation. The Great Consensus Cleanup proposes a fix.

Bitcoin's 'digital gold' status rests on two layers of decentralization — system and people/organization — and six structural features no later cryptocurrency combines to the same degree.

Every subsystem compared: Satoshi's v0.1 (January 2009) side by side with modern Bitcoin Core v27+, in split diagrams and tables by area.

How the Bitcoin ecosystem layers above and around the base chain: Lightning payment channels, federated sidechains, L1 envelope extensions, and mining pool architectures.

Bitcoin's threat model mapped end-to-end: what the protocol trusts, what it defends against, how each attack is countered, and where open risks remain.

How Bitcoin Core persists blocks, maintains the UTXO set, indexes chain state, manages the mempool, prunes historical data, and bootstraps via assumeUTXO.

How Bitcoin Core manages keys, constructs transactions, selects coins, estimates fees, and exposes functionality through RPC, REST, and ZMQ interfaces.

How Bitcoin uses elliptic-curve keys, digital signatures, hash functions, and deterministic derivation to secure ownership without trusted third parties.

How Bitcoin's 21 million cap emerges from a geometric halving series, how block rewards transition from subsidy to fees, and how the incentive model sustains honest mining.

How Bitcoin nodes find each other, exchange transactions and blocks, and resist network-level attacks across the P2P gossip layer.

How Bitcoin blocks are structured, how Merkle trees commit transactions to block headers, and how the most-work chain selection rule resolves forks.

How Bitcoin nodes agree on a single chain: SHA-256d proof of work, the difficulty adjustment algorithm, block validation rules, fork resolution, and probabilistic finality.

Where Bitcoin's current reality has drifted from Satoshi's design intent: four axes — mining (one-CPU-one-vote to ASIC oligopoly), custody (own keys to exchange IOUs), governance, and scaling.

Satoshi coded Bitcoin on Windows for 27 months, mainly with MinGW. In November 2009 he finished the Linux build Martti Malmi had started; by mid-2010 there were Windows, Linux and Mac releases.

How the 2010-08-15 overflow incident unfolded: the soft-fork rescue, why a 5-hour response was possible only then, what the transactions themselves show, and the centralization paradox.

Why Bitcoin's 2015-2017 fork wars were fights over what Bitcoin is, not OSS disputes: the authority vacuum after 2011, the money riding on rule choices, and three layers binding code to currency.

Gavin Andresen publicly announces taking on active project management for Bitcoin with Satoshi's blessing, creating the bitcoin/bitcoin GitHub staging tree and proposing a development process.

A reanalysis of van Dorst's stylometric corpus for the five most-cited candidates. Szabo led them, in the top 4.67% of 12,739 authors, but 594 unnamed authors came closer.

Aston University Centre for Forensic Linguistics released Project Bitcoin (April 2014): a stylometric study under Jack Grieve naming Szabo as the most likely whitepaper author among 11 candidates.

On April 13, 2024, Bas van Dorst published Where is Satoshi?, a large-scale stylometric corpus comparing Satoshi against 75,000+ cryptography mailing-list authors and 70,000+ Reddit commenters.

On February 22, 2021, Evan Hatch published Len Sassaman and Satoshi: a Cypherpunk history on Medium — the article that became the foundational case for the Sassaman = Satoshi Nakamoto hypothesis.

On December 1, 2013, blogger Skye Grey published Satoshi Nakamoto is (probably) Nick Szabo — the first public stylometric study naming Szabo as Satoshi, reported by TechCrunch on December 5.

On May 15, 2015, the New York Times published Nathaniel Popper's Decoding the Enigma of Satoshi Nakamoto — a Digital Gold excerpt naming Bit Gold designer Nick Szabo as Satoshi. Szabo denied it.

He conceived Bit Gold, and three of the four most-cited stylometric studies place him first. The evidence for Nick Szabo as Satoshi, weighed.

Hanyecz recalls his Satoshi correspondence around the April 19, 2010 macOS port. The private emails are unreleased; quotes are from later interviews. He called Satoshi paranoid, bossy, and weird.

Hanyecz recalls Satoshi's private pushback on his May 10, 2010 BitcoinTalk GPU-mining announcement. The verifiable element is the announcement; Satoshi's side comes from Hanyecz's later interviews.

Bitcoin v0.1 reuses one cypherpunk primitive (PoW from Hashcash), borrows general CS components (Merkle trees, linked timestamping, ECDSA), and synthesizes the rest (UTXO, mining, 21M cap, P2P).

On April 8, 2026, the New York Times published John Carreyrou's investigation naming Adam Back as the most likely Satoshi based on stylometric analysis. Back denied the identification.

Hashcash's inventor and the first person Satoshi contacted. In April 2026 the NYT named him the closest stylometric match among 620 cryptography-mailing-list writers. The evidence, weighed.

Satoshi has been hunted in public for years and left a large trail of material, yet remains unidentified. Why all that searching and all that material have not led to a name.

The "Satoshi Nakamoto" pseudonym read against the 1980s-90s cyberpunk and techno-orientalist field: a Japanese name on a crypto project arrived already evoking networked anonymous intelligence.

Three primary-source clues to Satoshi's place among the cypherpunks: he had not heard of b-money, Wei Dai called him "not previously active," and what Satoshi did tracked Hughes's 1993 manifesto.

BIP 125 formalized opt-in Replace-by-Fee (RBF), tracing directly to Satoshi's December 2010 BitcoinTalk replacement mechanism — the thread where Peter Todd made his second-ever forum post.

HBO documentary Money Electric (Cullen Hoback) named Peter Todd as a Satoshi candidate, citing a 2010 BitcoinTalk reply about RBF and Todd's later BIP 125. Todd called the claim ludicrous.

Benjamin Wallace's Wired feature — an early major mainstream article on Bitcoin. Traces the whitepaper, mining boom, Mt. Gox hack, and growing pains, ending with Garzik's "We really don't care."

Before reading the draft, Adam Back points Satoshi to Rivest's MicroMint paper; a 2025 profile quotes him calling his failure to read the whitepaper carefully 'probably my biggest mistake.'

Satoshi thanks Adam Back for the b-money reference and reveals he was not previously aware of Wei Dai's proposal. Historically significant line: 'my ideas start from exactly that point.'

Hal Finney's private email to Satoshi during pre-release code review, asking foundational scalability questions: 'How large do you envision it becoming? Tens of nodes? Thousands? Millions?'

Satoshi personally notifies Hal Finney of the Bitcoin v0.1 release hours after the public Cryptography list post, sending the SourceForge link and pointing him to bitcoin.org for release notes.

Satoshi's final email to Adam Back thanks Back for his reading suggestions and announces the software launch. The page also includes Hal Finney's project overview from the Cryptography mailing list.

Satoshi tells Finney that he cannot receive incoming connections from his location, revealing an operational constraint in the earliest days of the Bitcoin network.

Trammell asks what prevents the most powerful node from generating the majority of bitcoins — one of the earliest questions about mining centralization.

Trammell tells Satoshi about his proof-hashes Google Group, gives feedback on the credit field display, says he is running v0.1.1 and will upgrade, and offers to help test new features.

Trammell reports two issues upgrading from v0.1.0 to v0.1.3: the old process wouldn't exit, and all four generated coins showed 'Generated (not accepted)' — likely orphans from the communications bug.

Trammell shares his IP for Satoshi to send coins, says proof-hashes is open for posting, names the challenge of getting people to value bitcoins, and compares mining to a roulette wheel.

Satoshi responds to Trammell's MITM analysis by classifying attacks into two types (chain-of-communication vs. anyone on the Internet), proposes a combined IP+address fix, and notes wallet encryption.

Satoshi discusses dynamic IPs, asks permission to CC the conversation to bitcoin-list and the Cryptography mailing list, and envisions Bitcoin use cases including pay-to-send email and micropayments.

Trammell's detailed security analysis of Bitcoin's send-to-IP feature, identifying MITM vulnerabilities including ARP poisoning and ISP-level interception. Recommends always using Bitcoin addresses.

Satoshi copies his exchange with Trammell to bitcoin-list and the Cryptography list, sharing his Bitcoin vision including the famous line 'It might make sense just to get some in case it catches on.'

Satoshi reveals the wallet location (%appdata%\Bitcoin), explains that its transactional database (DBM) survives crashes and power loss, and says socket cleanup code is in the next release.

Trammell argues Bitcoin addresses are more secure than IP-based sending since they can be verified via multiple channels. He proposes an address-advertisement toggle and reports an exit socket bug.

Trammell confirms his IP is static, agrees to CC publicly, says he'll join bitcoin-list, reveals he started mining as an investment after Hal Finney's message, and discusses micropayment uptake.

Satoshi explains the 'Satoshi' label came from Trammell's own address book, that transactions show the receiving address (not the sender), and recommends per-payer addresses to identify payers.

Trammell reports confusion about a 100 BTC transfer between his own two Bitcoin instances — the transaction details showed 'Satoshi' as a label, leading him to wonder if Satoshi had sent the coins.

Satoshi explains the default address label is 'Your Address', suggests the mislabeling was a UI-driven user error, and acknowledges that per-payer receiving addresses have no real-world analogy.

Trammell realizes the confusing 'Satoshi' label was on his own receiving address, confirms he has multiple addresses at home, and asks if 'Satoshi' was the default since he doesn't recall setting it.

Trammell admits the mislabeling was his error, suggests changing 'Received with' to 'Received payment to' for clarity, and points to PayPal as the closest parallel to multiple addresses.

Satoshi responds to Hal Finney's botnet/pay-per-send point, proposing that fake mailboxes could 'reverse-spam' spammers by harvesting their POW tokens. He also describes e-gold's 'dusting' problem.

Nicholas Bohm, a retired British solicitor and early Bitcoin user, writes to Satoshi that after installing a new router, his Bitcoin client can no longer connect to the network.

Satoshi advises Bohm to forward port 8333 on his new router so his Bitcoin node can receive incoming connections: if nobody online can accept them, nodes can't connect at all.

Bohm reports to Satoshi that Bitcoin has failed to establish any connections for the last day or so, despite restarts. The next day he told Satoshi he usually had three to five connections.

Satoshi's candid reply to Bohm's connectivity issue, admitting there may be no other nodes running at that moment. He encourages Bohm to keep his server online so new users have someone to connect to.

Satoshi tells Bohm his node has been connected to 70.113.114.209 since the day before; if Bohm's node isn't connected to that address too, Bohm's node is cut off. The IP was later tied to Trammell.

Mike Hearn published The Resolution of the Bitcoin Experiment, declaring Bitcoin had failed due to governance breakdown and the block-size stalemate. He sold all his coins and left the project.

Mike Hearn testifies at the COPA v Wright trial, recounting his direct interactions with Satoshi and describing how Wright failed his technical check questions at a 2016 dinner.

In a CoinGeek interview, Mike Hearn offers rare reflections on Satoshi's personality — observing he enjoyed experimenting but appeared to grow frustrated when evangelical personalities arrived.

The COPA v Wright record revealed that Nicholas Bohm — previously known only for a January 2009 bitcoin-list bug report — also exchanged a private series of troubleshooting emails with Satoshi.

In an April 2025 interview, P2P Foundation founder Michel Bauwens recalled receiving several emails from Satoshi (who offered him a few bitcoins) and gave a retrospective on Bitcoin's significance.

In a LessWrong post, Wei Dai revealed that Satoshi had emailed him about Bitcoin v0.1 in early 2009, but that he ignored it because he was more interested in LessWrong than Cypherpunks at the time.

On his Unenumerated blog, Nick Szabo asks for help implementing bit gold, his 1998 design. No one responds. Six and a half months later, Satoshi publishes a whitepaper that never mentions bit gold.

Early Bitcoin developer Jeff Garzik released videos detailing his time working with Satoshi, describing the creator as a self-taught, solitary genius who never revealed any personal information.

Astrophysicist at Indiana University who posted on the cryptography list (Jan 17, 2009), raising concerns about government regulation and botnet exploitation — an early substantive Bitcoin critique.

Sergio Demian Lerner (1972–): Argentine cryptographer and blockchain researcher whose Patoshi analysis identified Satoshi as the dominant early miner, holding ~1.1M BTC and spending almost none.

The Bitcoin Forum, set up by Martti Malmi at bitcoin.org/smf, migrates to the independent bitcointalk.org domain in August 2011. Theymos managed the migration; all posts and accounts were preserved.

Reykjavik University researchers published the first peer-reviewed study of the Patoshi pattern in PLOS ONE, identifying two nonce anomalies (P and Z) and finding P in all of the first 64 blocks.

In a podcast interview, security researcher Dustin Trammell (Druid) describes being possibly the second node on the Bitcoin network — seeing only one other node for hours after first connecting.

Four and a half months after his ExtraNonce analysis, Lerner found Satoshi's nonce values had a non-random LSB distribution — a second fingerprint of custom mining software with nonce partitioning.

Lerner's 2019 post The Return of the Deniers and the Revenge of Patoshi coined the name Patoshi and, from the absence of timestamp inversions, showed the blocks came from one PC's clock.

Whale Alert independent analysis confirmed Satoshi mined 1,125,150 BTC across 22,503 of the first 54,316 blocks, claiming ~48 computers (later disputed by Lerner's single-PC simulation).

Doncho Karaivanov analyzes the timestamps of 742 posts, commits and emails by Satoshi, plus the Times headline in the genesis block and his British spelling, to argue Satoshi was based in London.

Jameson Lopp shows Satoshi deliberately throttled mining capacity, earning ~1.1M BTC when full capacity could have yielded ~2.19M BTC. Anyone claiming Satoshi was greedy hasn't done the math.

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.

Sergio Demian Lerner published The Well Deserved Fortune of Satoshi, identifying a distinctive mining pattern (later named Patoshi) linking ~22,000 blocks (~1.1M BTC) to a single miner.

CoinDesk published previously unseen Satoshi-Finney emails (obtained via widow Fran Finney): Finney's November 2008 scalability question and Satoshi's personal v0.1 release notice on January 8, 2009.

Craig Wright declared himself Satoshi in coordinated interviews with the BBC, The Economist and GQ. The cryptographic proof on his blog was soon debunked: he had reused a 2009 transaction signature.

Craig Wright sued bitcoin.org operator Cobra over Bitcoin whitepaper copyright. Cobra refused to reveal his identity, resulting in a default judgment ordering bitcoin.org to remove the whitepaper.

Adam Back reflects on his August 2008 email exchange with Satoshi, his regret at not reading the whitepaper carefully, and his testimony in COPA v Wright, where the full email thread became public.

During Day 13 of COPA v Wright, Martti Malmi testified via video link and submitted 260 emails (140,000 words) exchanged with Satoshi between May 2009 and February 2011, published on GitHub.

Satoshi Nakamoto's earliest known email. He contacts Adam Back to verify the Hashcash paper citation and shares a pre-release draft titled 'Electronic Cash Without a Trusted Third Party' (ecash.pdf).

Adam Back confirms the Hashcash citation and suggests Satoshi look at Wei Dai's b-money proposal. This referral led Satoshi to contact Wei Dai and cite b-money in the Bitcoin whitepaper.

The first known tweet about Bitcoin. Hal Finney posted 'Running bitcoin' two days after Bitcoin v0.1 was released, on January 10/11, 2009. He was the first known person other than Satoshi to run it.

One of the first major print magazine features on Bitcoin. Greenberg interviews Andresen, who calls Bitcoin "better gold than gold." Satoshi's withdrawal signals predate it by seven months.

Nick Szabo's May 2011 blog post on why digital cash took eleven years to get from bit gold (1998) to Bitcoin (2009). It names libtech as the private list where bit gold and b-money grew in parallel.

Security researcher Dan Kaminsky tries to find vulnerabilities in Bitcoin and fails. "I came up with beautiful bugs. But every time I went after the code there was a line that addressed the problem."

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.

Tim Swanson's comprehensive interview with Ray Dillinger for the Bitcoin whitepaper's 10th anniversary. Dillinger reveals technical details of his code review, including the floating-point discovery.

Jeff Garzik, one of Bitcoin's earliest core developers, reflects on his work with Satoshi. He discovered Bitcoin via a July 2010 Slashdot post and became one of the top three contributors.

Satoshi Nakamoto registered the 'bitcoin' project on SourceForge.net, establishing the first public repository and project page for Bitcoin's source code and releases.

Bitcoin's first block carries a Times headline about a bank bailout — the one personal touch Satoshi left anywhere in the design. A reading of why he chose it.

Satoshi Nakamoto released Bitcoin v0.1, the first public release of the Bitcoin software, on SourceForge. This Windows-only release made it possible for anyone to run a Bitcoin node and mine coins.

Satoshi replies to Dustin Trammell, explaining the coin maturity system and recommending an upgrade to version 0.1.3 which had stabilized the software.

Dustin Trammell's first email to Satoshi after running the Bitcoin alpha. He reports how it ran, mentions a public timestamp service, and asks about coin maturity (new coins showing 0.00 credit).

Satoshi informs Trammell that bugs are fixed in v0.1.3 and offers to send him some coins via the send-to-IP feature. The payment became one of the earliest known direct Bitcoin transfers.

Bitcoin v0.2 was released on SourceForge, introducing Linux support, multi-processor mining, proxy support for Tor, and GUI improvements contributed by Martti Malmi.

Hanyecz recalls that when he shared his GPU miner, Satoshi sent his own GPU mining code in return, kept to defend against a possible 51% attack rather than for mining. From later interviews.

Gavin Andresen begins corresponding with Satoshi after discovering Bitcoin in May 2010 and starts submitting code contributions. He creates the Bitcoin Faucet to give away free BTC and boost adoption.

Bitcoin v0.3 was released on SourceForge with JSON-RPC control, a daemon version, Mac OS X support, and 20% faster hashing, coinciding with the famous Slashdot posting.

Emergency release of Bitcoin v0.3.10 to fix a value overflow vulnerability exploited to create 184 billion bitcoins in a single transaction. Satoshi coordinated the rapid soft-fork deployment.

Bitcoin v0.3.12 was released on SourceForge with standard JSON-RPC error objects, a new backupwallet RPC command, and various network stability enhancements.

Bitcoin v0.3.18 was released on SourceForge, one of Satoshi's last releases, featuring wallet compatibility fixes and Gavin Andresen's accounts-based JSON-RPC commands.

No single day handed Bitcoin to Gavin Andresen: his own commits from October 11, a server-admin pick on December 3, Satoshi's last post on December 12, and his December 19 announcement.

Bitcoin v0.3.19 was released on SourceForge as Satoshi Nakamoto's final release, adding DoS protections and removing safe mode alerts before his departure.

Gavin Andresen replies to Satoshi's final email, accepting the alert key and disclosing that he has been invited to present Bitcoin to US intelligence agencies. Satoshi never replies to this message.

Satoshi's last known private email. He transfers the Bitcoin network alert key to Gavin Andresen, asks him to stop portraying him as a 'mysterious shadowy figure,' and says he has moved on.

Satoshi's first reply to Martti Malmi, who had offered to help with Bitcoin. Satoshi praises Malmi's understanding of Bitcoin and asks him to help write website content and a FAQ.

In earlier answers compiled for Malmi, Satoshi weighs Bitcoin's energy use against banking's costs and names the tension between economic liberty and conservation.

Malmi agrees to develop the Bitcoin website and FAQ, proposes password-protected private keys, and reports running a Bitcoin node 24/7.

Satoshi approves Malmi's first FAQ draft with small fixes. His warning against pitching Bitcoin as an investment, 'we can't pitch it as that,' came five weeks later, on June 11, 2009.

Satoshi suggests using the word 'cryptocurrency' to describe Bitcoin and asks Malmi to remove investment language from the site - a key moment in Bitcoin's branding history.

Malmi proposes a Bitcoin-to-euro exchange service. Satoshi answers with a fixed support-price idea and says he will not run an exchange himself; Malmi's own bitcoinexchange.com followed in 2010.

Satoshi emphasizes that autostart with minimize-to-tray is 'a must-have feature' for network growth, comparing it to early file-sharing strategies. Implemented by Malmi for Bitcoin 0.2.

Satoshi warns Malmi to de-emphasize Bitcoin's anonymity claims, distinguishing between anonymity and pseudonymity - a prescient warning about privacy expectations.

Malmi, wanting more bitcoin.org server admins after an outage, offers the root password to Satoshi and one more person; Satoshi answers that the other person should be Gavin Andresen.

Satoshi's last email in the Malmi archive (Feb 22, 2011): a reply to Gavin, copied to Martti, handing each of them the bitcoin-list mailman password in a PGP-encrypted block.

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.'

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.

Wired and Gizmodo simultaneously publish articles identifying Australian computer scientist Craig Steven Wright as the probable creator of Bitcoin, based on leaked documents and emails.

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.

Multiple blockchain analyses estimate that Satoshi Nakamoto mined approximately 1.1 million bitcoins in Bitcoin's earliest days, with the vast majority of these coins never having been spent.

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.

Satoshi Nakamoto's post: "[bitcoin-list] Welcome".
