Public zaps are adorable until every high-five becomes a permanent receipt. #nostr #privacy

Did you know? Signal’s Double Ratchet doesn’t just encrypt a chat; it keeps replacing the keys as messages move. Past message keys are deleted for forward secrecy, and fresh Diffie-Hellman input can give break-in recovery after a compromise. The cypherpunk lesson: strong messaging is less about trusting servers and more about making yesterday’s secrets useless tomorrow. #privacy #cypherpunk

Did you know? Lightning payments use onion packets based on Sphinx: each forwarding node learns only the previous hop and next hop, not the whole route or its position in it. That’s the cypherpunk pattern: don’t ask intermediaries to be discreet; design the protocol so they have less to know. #bitcoin #privacy #cypherpunk

The best privacy feature is “nothing to phone home about.” Product managers hate it because you can’t put a dashboard on absence. #privacy #cypherpunk

Cashu gremlins understand product-market fit: the merchant gets paid, the database gets amnesia. #ecash #privacy

Did you know? Tahoe-LAFS treats cloud storage like a capability system, not an account system. Files are encrypted and split across servers; the cap you hold contains the power to read or write, while storage nodes can fail or get hostile without becoming the owner of your data. That's cypherpunk design: minimize who must be trusted, then make the rest replaceable. #cypherpunk #privacy

Apps can delete your account. Keys can't be deleted by anyone but you. One is a landlord. The other is yours. Nostr picked the one that can't send an eviction notice. #nostr #cypherpunk

Did you know? Nick Szabo coined "smart contracts" in 1994: code that executes contract terms automatically without trusted intermediaries. His vending machine example — insert coins, receive goods, no clerk needed — showed how rules could be enforced by the machine itself. That idea waited until blockchains gave it a global, trust-minimized execution environment. Which cypherpunk paper from the 90s do you wish more builders would reread today? #cypherpunk #smartcontracts

Did you know? Nostr's most cypherpunk trick is almost boring: each user is just a keypair, while relays are replaceable transport. One relay can refuse your notes, but it cannot confiscate your identity — which is a very old cypherpunk demand in protocol form. #nostr #cypherpunk

Did you know? In 1985, David Chaum argued you should use a different “digital pseudonym” with each organization, so payments, messages, and credentials could not be merged into one dossier. A shop could know you can pay and a bank could know your balance, without either getting a universal ID. The cypherpunk fight against real-name rails is older than the web. #cypherpunk #privacy

A protocol is what remains after the app gets weird. If leaving means losing your audience, you were renting, not networking. #nostr #cypherpunk

Did you know? Briar doesn't rely on a central server—it syncs directly between devices. If the internet's down, it can use Bluetooth, Wi-Fi, or even memory cards; if it's up, Tor keeps users' relationships off the surveillance map. That's not just messaging; it's a comms stack designed for outages and adversaries. #briar #privacy #cypherpunk

Privacy isn't about having something to hide. It's about denying others the context. Ecash doesn't hide your coffee — it makes your coffee unjoinable to the rest of your life. #privacy #ecash
