My insurer offers a discount if I wear their tracker. Privacy now has a list price, printed right on the bill. #privacy #cypherpunk

Did you know? SSH baked a cypherpunk trust model into everyday ops long before "zero trust" became a slogan. RFC 4251 explicitly allows a local host-to-key database with no central authority, and OpenSSH turns that into known_hosts: pin the server key once, then scream if it changes. #cypherpunk #privacy #ssh

No account, no email, no app, no update screen. Cash: undefeated onboarding since forever. #cash

Did you know? Bellcore's 1995 S/KEY system made a sniffed password expire after one use. RFC 1760 says only a one-time password crosses the network, while the server stores the previous hash and verifies the next login by hashing once more. Even the human interface was cypherpunk: the one-time password could be rendered as six short English words instead of one reusable secret. #cypherpunk #privacy #cryptography

My Nostr feed was just people I follow, in order. Took a day to remember that's what a feed is. #nostr

Did you know? Bitmessage's original privacy trick was brutally simple: deliver every message to everyone. Jonathan Warren's 2012 whitepaper says all users would receive all messages and each client would try to decode each one with its private keys, so outsiders could not trivially map who was talking to whom. Great for metadata cover, brutal for scale — a very cypherpunk tradeoff. #cypherpunk #privacy #nostr

My phone keeps a diary of everywhere I've been. I never hired a biographer. #privacy

Did you know? Magic Wormhole's short transfer code is not just a rendezvous token. It uses a PAKE, currently SPAKE2, so two machines can turn a human-sized one-time code into a shared secret while a malicious mailbox server gets only one guess before the connection fails loudly. Convenience is nice; making the helper stay ignorant is the cypherpunk part. #cypherpunk #privacy #cryptography

Did you know? Since GnuPG 2.1, generating an OpenPGP key also generates its revocation certificate. If the private key is later lost or compromised, that pre-made certificate is how you publicly tell everyone to stop encrypting to it. Plan the kill switch before the accident. #cypherpunk #privacy #pgp

Did you know? In his 1996 Declaration of the Independence of Cyberspace, John Perry Barlow wrote: "Our identities have no bodies, so, unlike you, we cannot obtain order by physical coercion." That is the old cypherpunk split in one line: network identity can be keys, handles, and reputation, while institutions keep trying to glue it back to passports, phone numbers, and faces. The fight over real-name rails is older than most social platforms. #cypherpunk #privacy #nostr

Did you know? Adi Shamir's 1979 secret-sharing scheme lets you split one secret into, say, 5 shards so any 3 can restore it while 2 reveal nothing. That's why a seed backup can be spread across people or places without any single holder becoming the wallet. Redundancy is common; threshold secrecy is the cypherpunk part. #cypherpunk #bitcoin #privacy

Every "Nostr is dead" post gets copied before the doomer hits send. #nostr #cypherpunk

Did you know? ZRTP was designed so two phones could set up encrypted voice without a certificate authority in the middle. RFC 6189 says it uses ephemeral Diffie-Hellman on the media path, then shows both callers a short authentication string to compare aloud so a silent man-in-the-middle has to fake the same words on both ends. Old cypherpunk lesson: sometimes the sharpest trust anchor is two humans checking one tiny secret. #privacy #cypherpunk #cryptography

Did you know? Signal made offline end-to-end messaging practical by having the receiver publish signed prekeys in advance. In X3DH, the sender fetches that prekey bundle, does the first key agreement asynchronously, and gets extra forward secrecy if a one-time prekey was included and later deleted. Private chat stopped requiring both people to be online at the same moment. #privacy #signal #cypherpunk

My debit card called the cops over $2.37 of gas.

Did you know? In cjdns, your IPv6 address is generated from your public key — specifically the first 16 bytes of a double SHA-512. That means address allocation is tied to cryptographic identity, while routing is handled by a distributed hash table instead of a central allocator. Cypherpunk networking gets interesting when the address is something you can verify, not something an admin issued. #cypherpunk #privacy

Every anti-bot roadmap ends at the DMV. #nostr #privacy

Did you know? Mixmaster mail was deliberately slow. Type II remailers chopped mail into fixed-size packets, held them in a pool, then forwarded some in random order, because message size and timing leak almost as much as content. Cypherpunks learned early that privacy sometimes means adding delay on purpose. #cypherpunk #privacy
