"Privacy is necessary for an open society in the electronic age." — Eric Hughes, A Cypherpunk's Manifesto, 1993

A permanent offline mirror of the Extropy-Chat mailing list archives, with a focus on messages from Hal Finney, Nick Szabo, Wei Dai, Adam Back, Tim May, and other cypherpunks and digital-cash pioneers.

The Extropy lists were a key intellectual node in the 1990s–2000s where transhumanists, cryptographers, AI researchers, and libertarian technologists converged. Hal Finney posted here throughout his career — from PGP development to RPOW to his last years after Bitcoin.

This archive ensures those conversations survive even if lists.extropy.org goes down permanently.

The reader works entirely offline once vault_data/ is populated.

• Thread view — full conversation trees, not just individual messages
• Author spotlight — biographical cards for Hal Finney and key cypherpunks
• Priority filter — one click to see only Hal + cypherpunk messages
• Timeline sidebar — navigate by month; sparkbar shows message density
• Full-text search — across subjects, authors, and message bodies
• Quote detection — distinguishes original text from cited replies
• Dark terminal aesthetic — because it fits

The scraper watches for messages by (or mentioning):

• Hal Finney, Nick Szabo, Wei Dai, Adam Back
• Tim May / tcmay, Eric Hughes, John Gilmore
• Whitfield Diffie, Ralph Merkle, Len Sassaman
• Phil Zimmermann, Zooko Wilcox-O'Hearn, Ian Grigg
• Max More, Robin Hanson, Eliezer Yudkowsky
• Keywords: cypherpunk, b-money, e-gold, digicash, hashcash, chaum

To add other mailing lists (e.g. the original Cypherpunks list, cryptography@metzdowd.com), edit vault_scraper.py and change BASE_URL. The parser handles standard Pipermail archives.

For non-Pipermail sources, the parse_message() function can be adapted.
