What the Cypherpunks Were

The Cypherpunks were a loosely organized movement of cryptographers, programmers, and activists that formed in the early 1990s. Their thesis: cryptography could be used to protect individual privacy and freedom against state surveillance and control — and the best way to advance this was to write code rather than lobby politicians.

The mailing list (founded 1992 by Eric Hughes, Timothy May, and John Gilmore) was the primary forum. At peak it had thousands of subscribers including Satoshi Nakamoto.

The Cypherpunks Manifesto (Eric Hughes, 1993)

Key lines:

  • “Privacy is necessary for an open society in the electronic age.”
  • “Privacy is not secrecy. A private matter is something one doesn’t want the whole world to know, but a secret matter is something one doesn’t want anybody to know. Privacy is the power to selectively reveal oneself to the world.”
  • “Cypherpunks write code. We know that someone has to write software to defend privacy, and since we can’t get privacy unless we all do, we’re going to write it.”

The Crypto Anarchist Manifesto (Timothy May, 1988/1992)

Written in 1988, distributed at “Crypto 88” conference, published on the mailing list in 1992. May predicted:

  • Cryptography will enable untraceable transactions and communications
  • This will fundamentally undermine the state’s ability to tax and regulate
  • A new form of social order (crypto-anarchy) will emerge — not chaos, but voluntary cryptographic contracts

Bitcoin fulfilled this prediction. May died in 2018 — not long enough to see Bitcoin become a trillion-dollar asset, but long enough to see SegWit.

”Libertaria in Cyberspace” (Timothy May, 1992)

Physical libertarian experiments (seasteading, special economic zones) fail because states can use physical force. Cyberspace is structurally different: no territory to invade, no bodies to coerce, cryptography enforces contracts. A libertarian polity in cyberspace is inherently more stable than any physical one.

The Progression to Bitcoin

The cypherpunks tried repeatedly to build digital cash:

ProjectYearCreatorProblem
eCash / DigiCash1989David ChaumRequired trusted central mint; company went bankrupt
Hashcash1997Adam BackAnti-spam PoW; non-transferable
b-money1998Wei DaiProposed but never implemented
Bit Gold1998–2005Nick SzaboRequired trusted timestamping service
RPOW2004Hal FinneyTransferable PoW tokens but required trusted server
Bitcoin2008SatoshiSolved all prior problems

Satoshi Nakamoto explicitly cited Hashcash (Back) and b-money (Dai) in the whitepaper.


PGP: The First Victory

PGP (Pretty Good Privacy), created by Philip Zimmermann in 1991, was the first practical mass-market encryption tool. Zimmermann was investigated criminally by the US government for exporting cryptography (then regulated as a munition). The case was eventually dropped — a key cypherpunk victory establishing that encryption was speech, not a weapon.

This fight over encryption policy is the direct ancestor of today’s debates over Bitcoin and financial privacy.
