Summary
The original Bitcoin whitepaper: “Bitcoin: A Peer-to-Peer Electronic Cash System.” Nine-page paper published October 31, 2008 — six weeks after Lehman Brothers collapsed — describing a trustless digital cash system using proof-of-work, blockchain ledger, and cryptographic signatures without requiring a trusted third party. Satoshi Nakamoto’s pseudonymous authorship has never been resolved.
Key Points
- Proposes a peer-to-peer electronic cash system that bypasses financial intermediaries. Nine pages.
- Core innovations: blockchain as append-only ledger, proof-of-work as Sybil resistance, longest-chain rule for consensus, 21M supply cap via halving schedule.
- Section 4 (Proof-of-Work) explicitly cites Adam Back’s Hashcash by name: “a proof-of-work system similar to Adam Back’s Hashcash.” Reference [6]: A. Back, “Hashcash - a denial of service counter-measure,” 2002. This makes Back the only living person named in the whitepaper’s technical body.
- Also cites Wei Dai’s b-money and Nick Szabo’s prior work in the references. Hal Finney is not cited but was the first person to receive a Bitcoin transaction.
- Identity of Satoshi Nakamoto remains unknown (individual or group pseudonym).
- Published October 31, 2008 — 46 days after Lehman Brothers filed for Chapter 11 (September 15, 2008).
Newsletter Angles
- The whitepaper’s timing (2008 financial crisis) is its implicit argument: the financial system failed, here’s an alternative.
- The 21M cap is Satoshi’s answer to the Nixon Shock problem — hard money that governments can’t inflate.
- Section 4’s explicit Hashcash citation is one of the factual pillars of the NYT’s April 2026 Adam Back investigation — Back is not just a cypherpunk contemporary of Satoshi; he is the only living person cited by name in the whitepaper’s technical sections.
- The “peer-to-peer electronic cash” vision is what El Salvador tried to implement and failed; stablecoins are a different answer to the same problem.
Entities Mentioned
- Satoshi Nakamoto — pseudonymous author; identity unknown
