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.

A consensus mechanism built on its own clock, an issuance rate that keeps shrinking without a cap, and a supply that started with a premine to the foundation and its investors.

A relay chain coordinating parachains, nominated proof-of-stake, and the 2025 vote that capped a supply that had never had a ceiling -- Polkadot's design, read against Bitcoin's fixed 21 million.

A hundred billion units generated in a single stroke in June 2012, a validator list two organizations curate, and a five-year SEC lawsuit over who was allowed to sell them.

Launched on Bitcoin's blockchain as Realcoin in 2014, USDT mints and freezes at one company's discretion, and its reserve reporting has stayed at quarterly attestations, not audits.

Cross-cutting reading of iconic Bitcoin losses by mechanism: forgotten password (Thomas), physical disposal (Howells), custody-collapse (QuadrigaCX, Mt. Gox, FTX). Tied to Bitcoin's irreversibility.

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.

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.

El Salvador's legislature voted 55-2 to end mandatory bitcoin acceptance under a $1.4B IMF deal that also capped public-sector bitcoin buying at zero — a line the government kept testing anyway.

James Howells says he bagged the wrong hard drive in a 2013 clear-out, and it went to a Newport, Wales landfill with his early bitcoin keys. In January 2025 the High Court threw out his £495M claim.

Forensicxs published a line-by-line walkthrough of Bitcoin v0.1's 31,794 lines of source code, covering all 31 files.

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.

Nayib Bukele rose to El Salvador's presidency, made Bitcoin legal tender in 2021, and repealed its mandatory-acceptance clause in 2025 under IMF pressure while reported holdings kept growing.

El Salvador's Bitcoin Law took effect on September 7, 2021, requiring merchants nationwide to accept bitcoin and launching the government's Chivo wallet with a $30 sign-up incentive.

In September 2021, China's NDRC banned new bitcoin mining and its central bank outlawed all virtual-currency business, two years after seizing 194,775 BTC from the PlusToken Ponzi scheme.

Cobra's response on X, posted hours after the London High Court ordered bitcoin.org to remove the Bitcoin whitepaper following Craig Wright's default judgment.

Stefan Thomas made an early viral Bitcoin explainer video and an early JS toolkit, became Ripple's CTO, and co-created Interledger — all while locked out of 7,002 BTC since around 2011.

Stefan Thomas was paid 7,002 BTC in 2011 for a Bitcoin explainer video, stored the keys on a 10-attempt IronKey, and lost the password. By the 2021 NYT report, 2 of 10 attempts remain.

Canadian exchange QuadrigaCX collapsed after CEO Gerald Cotten died in India (Dec 2018). C$250M owed to ~115,000 customers became inaccessible. The OSC later ruled it was a long-running fraud.

Gerald Cotten ran online Ponzi schemes as a teenager, founded QuadrigaCX in 2013, and defrauded its customers for years before dying in India in 2018 with the only copies of its keys.

Qualcomm engineer who wrote the Proof of History paper and founded Solana. Calls Bitcoin's proof-of-work a masterpiece and says the asset has no value beyond insurance.

On January 15, 2016, Bitcoin Core v0.12 replaced OpenSSL with libsecp256k1 — Wuille and Maxwell's custom elliptic-curve library — for consensus-critical ECDSA verification.

Fran Finney: wife of Hal Finney (the first known person other than Satoshi to run Bitcoin). She witnessed Bitcoin's earliest moments, cared for Hal through ALS, and became the keeper of his legacy.

He built RPOW, received the first Bitcoin transaction, and lived blocks from Dorian Satoshi Nakamoto. The evidence for Hal Finney as Satoshi, weighed.

March 25, 2014 Forbes feature: Andy Greenberg followed the Temple City coincidence to Hal Finney, then dropped the theory after seeing Finney's 2009 emails with Satoshi and his wallet record.

Editorial reading of how the 2014 'Bitcoin Core' rebrand reshaped Bitcoin's authority vocabulary — PR #3408 internal disagreement, the 2015-2017 fork episodes, and Hearn's 2025 retrospective regret.

Mt. Gox — once the world's largest Bitcoin exchange handling ~70% of transactions — filed for bankruptcy protection in Tokyo. CEO Mark Karpeles revealed ~850,000 BTC (~$450M) had been lost.

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.

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.

In 2010, Marek Palatinus proposed Bitcoin's first mining pool. He went on to co-design the Stratum protocol, co-found Trezor, and co-author BIP-39, the seed-phrase standard nearly every wallet uses.

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

An integer overflow (CVE-2010-5139) let Block 74638 create 184 billion BTC. Satoshi released a fix 5h 40m after discovery; the fixed chain overtook the bad one about 15 hours after the block.

Structural reading of the 2010-08-15 overflow incident — soft-fork rescue mechanics, why a 5-hour response was only achievable then, transaction-shape forensics, and the centralization paradox.

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.

Satoshi and Malmi spent 2009 to 2010 correcting the bitcoin.org FAQ word by word — and Satoshi was still the address readers wrote to when it broke. None of that wording survives on bitcoin.org today.

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.

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

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.

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 reveals the wallet location (%appdata%\Bitcoin), explains it uses a transactional database (DBM) safe from crash/power loss, and confirms socket cleanup code is added for 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.

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

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

Technical analysis of Bitcoin's genesis block from v0.1 source: hardcode auto-construction, the five-day gap as timestamp artifact, two-layer authorship reading, PoW headroom, key possession.

Cross-cutting architecture comparison across every subsystem: Satoshi's v0.1 (January 2009) side by side with modern Bitcoin Core v27+, with split diagrams and domain tables.

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.

Deep-dive into Bitcoin's transaction layer: UTXO lifecycle, transaction structure, Script evaluation, ECDSA and Schnorr signatures, SegWit, and Taproot.

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.

High-level system overview of Bitcoin's architecture, layer model, and data flow. Entry point to a 12-page design-document series covering every major subsystem.

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 25,489 reachable addresses, and why, with no reward.

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.

Reads the asymmetry between public attempts to identify Satoshi, the surviving material trail, and the persistent identification gap.
