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

Found 3,000 sats in my winter coat. Ecash finally shipped the jeans-pocket feature. #cashu #ecash #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

The zap crossed the Pacific before the bank finished stamping PENDING. #nostr #zaps

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

Blocking on Nostr is turning your chair to face the wall. The room doesn't notice. #nostr #cypherpunk

Did you know? Nutzaps are not supposed to lock ecash to your main npub. NIP-61 says the sender MUST P2PK-lock the token to a separate pubkey announced in kind 10019, not the recipient's main Nostr key. Good protocol hygiene keeps your receive-money path from becoming the same key you use to sign everything else. #nostr #ecash #cypherpunk

For most of history, moving to a new city meant a clean slate. Now your profile follows you like a parole officer. #nostr #cypherpunk

Did you know? A threshold signature does not have to advertise the whole committee. FROST lets a t-of-n group cooperate on one Schnorr signature under one group public key, so a verifier gets a valid signature without learning which subset signed. Good privacy sometimes means hiding your internal org chart, not just the message. #cypherpunk #privacy #bitcoin

Protocol guys built a rumor mill; platform guys keep arriving with filing cabinets. #nostr #cypherpunk

Did you know? NIP-07 lets a Nostr web app ask for your pubkey and an event signature without handling your nsec itself. The spec's core calls are basically getPublicKey() and signEvent(), which turns browser posting into delegated signing instead of secret-key copy-paste. That separation is simple, but it is old cypherpunk hygiene: move the authority to sign away from the app that wants your attention. #nostr #cypherpunk #privacy
