From Satoshi's whitepaper to spot ETFs — the genesis of digital money.
Satoshi Nakamoto publishes "Bitcoin: A Peer-to-Peer Electronic Cash System" to the Cryptography mailing list. Nine pages that would reshape global finance — proposing a trustless digital currency using proof-of-work and a distributed timestamp server.
Block 0 is mined with the now-famous message: "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks". The Bitcoin network begins. Block reward: 50 BTC.
Satoshi sends 10 BTC to Hal Finney — the first-ever Bitcoin transaction. Finney, a legendary cypherpunk who created the first reusable proof-of-work system, was one of Bitcoin's earliest supporters.
Laszlo Hanyecz pays 10,000 BTC for two Papa John's pizzas — the first known commercial Bitcoin transaction. At today's prices, the most expensive pizzas in history.
Satoshi Nakamoto makes their last public forum post in December 2010, with final private emails to Gavin Andresen in April 2011. The creator of Bitcoin vanishes, leaving behind ~1 million unmoved BTC and the most influential open-source project in financial history.
9 key upgrades · 2012–2024
Pay-to-Script-Hash enables complex scripts behind simple addresses. Foundation for multi-signature wallets and future smart contract capabilities. Proposed by Gavin Andresen.
Bitcoin Core 0.9.0 enables 40 bytes of arbitrary data in transactions (later raised to 80 bytes in 0.11.0). Opens the door for timestamping, colored coins, and metadata embedding — a controlled compromise for data storage.
BIP-65 — time-locked transactions become possible. Essential building block for payment channels and the Lightning Network. Authored by Peter Todd.
The landmark upgrade after the Blocksize War. Separates witness data, fixing transaction malleability and increasing effective capacity to ~4 MB per block. Enables Lightning Network. Catalyzed by the BIP-148 UASF movement.
Lightning Labs launches mainnet beta. Layer 2 payment channels enable near-instant, near-free transactions. Conceptualized by Joseph Poon and Thaddeus Dryja in 2015.
Bitcoin's biggest upgrade since SegWit. Schnorr signatures + MAST improve privacy and efficiency. Complex scripts look identical to simple transactions on-chain. Proposed by Gregory Maxwell.
Casey Rodarmor launches Ordinals — inscriptions directly on Bitcoin using Taproot's witness space. NFTs and BRC-20 tokens arrive on Bitcoin. Over 60 million inscriptions in the first year. Highly controversial.
SEC approves 11 spot Bitcoin ETFs after a decade of rejections. BlackRock's IBIT becomes the fastest ETF to reach $10B AUM in history. Wall Street meets Satoshi's creation.
The next frontier: OP_CAT (BIP-347), OP_CTV, and OP_VAULT proposals aim to enable covenants — programmable spending conditions. The most active protocol debate since SegWit.
Three BIPs that defined Bitcoin's soul
The culmination of the Blocksize War (2015–2017) — the most contentious debate in Bitcoin's history. Small blockers vs. big blockers. The community chose a soft fork over a hard fork, preserving backward compatibility.
Bitcoin Cash (BCH) forked off Aug 1, 2017 as the big-block alternative. Bitcoin kept its 1MB base + SegWit discount.
Bundles three BIPs: Schnorr signatures (340), Taproot (341), and Tapscript (342). Unlike SegWit, activation was smooth — 90% miner signaling via "Speedy Trial."
Unlocked Ordinals inscriptions as an unintended consequence — reigniting the debate about Bitcoin's purpose.
Proposed by Paul Sztorc, Drivechains would allow sidechains secured by Bitcoin miners. The most contentious active proposal — supporters see it as Bitcoin's extensibility layer; critics warn it could incentivize miner centralization.
Still unactivated after 7+ years. Reflects Bitcoin's intentionally slow, conservative governance process.
No foundation, no core team, no formal voting. Bitcoin governance is rough consensus among nodes, miners, developers, and users. The UASF movement proved that users — not miners — hold ultimate power. Code is proposed via BIPs and activated only when the network agrees.
From Silk Road to Wall Street
Ross Ulbricht operates the first major darknet marketplace, putting Bitcoin in the spotlight for illicit use. FBI seizes ~144,000 BTC. Shapes the "Bitcoin is for criminals" narrative that takes years to overcome.
The world's largest Bitcoin exchange loses 850,000 BTC (~$450M at the time). Files for bankruptcy. The defining "not your keys, not your coins" moment. Price crashes from $850 to under $400.
Founded by Adam Back (inventor of Hashcash) and Gregory Maxwell. Develops Liquid sidechain and employs several Bitcoin Core developers. Central figure in the Blocksize War.
Founded by Elizabeth Stark and Olaoluwa Osuntokun. Primary implementor of the Lightning Network. Later develops Taro (Taproot Assets) — bringing stablecoins and assets to Lightning.
President Nayib Bukele makes Bitcoin legal tender — the first country in history. Launches the Chivo wallet and begins buying BTC for the national treasury. Controversial but historic.
Michael Saylor begins converting corporate treasury to Bitcoin. By 2025, Strategy holds over 500,000+ BTC — the largest corporate Bitcoin holder. Pioneered the corporate treasury strategy that dozens of companies now follow.
After 10+ years of rejections, the SEC approves spot Bitcoin ETFs. BlackRock, Fidelity, Ark, and 8 others launch simultaneously. Combined AUM exceeds $100B+ in the first year.
