Video: ₿itcoin Whitepaper - 9 Pages That Changed The World Date: 2008-10-31 · Type: manifesto · Tags: satoshi, whitepaper, peer-to-peer, cypherpunk, proof-of-work, financial-crisis, pseudonymity A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution. Halloween, the deepest year of the financial crisis: a pseudonym posted a nine-page PDF to Perry Metzger's cryptography mailing list — the same list that had hosted the cypherpunks' second-act diaspora after the 1990s. The paper was technically modest in its components. Proof-of-work was Adam Back's hashcash. Hash-chains were Stuart Haber and Scott Stornetta's. The digital cash framing owed debts to Wei Dai's b-money and Nick Szabo's bit gold, neither of which Satoshi cited in the initial post. What the paper did that none of its precursors had managed was compose these parts into a working system that required no mint, no trusted third party, no Digicash-style company to go bankrupt and take the coins with it. Reception on the list was cool. James A. Donald's first reply acknowledged the need for such a system and immediately doubted the paper's scaling properties. Ray Dillinger raised the energy costs of proof-of-work. The scepticism was earnest and technically grounded, and it was largely wrong about what mattered — the paper was not primarily an engineering proposal but a political one dressed in engineering clothes. Tim May's 1988 declaration that "a specter is haunting the modern world, the specter of crypto anarchy" had been waiting fifteen years for a proof of concept; Satoshi provided it without once mentioning the cypherpunk tradition by name. The paper was never peer-reviewed, never formally published, never revised after the initial version. It circulated as a PDF and accumulated a world. Its eight references are almost comically sparse for a document that rewired global finance. The opening line's flat declarative refusal of metaphor — no manifesto rhetoric, no appeal to freedom, just a system description — was itself a kind of style choice that would echo through every subsequent serious protocol paper in the field.
