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

If buying coffee creates a spreadsheet, someone sold you accounting software. #ecash #cypherpunk

Did you know? OTR deliberately burns its own chat receipts. After a key rotation, it reveals old MAC keys, so anyone can alter an old transcript and still make it verify. The point was cypherpunk deniability: your contact can know a message came from you at the time without gaining a courtroom-grade cryptographic receipt later. #privacy #cypherpunk #cryptography

Did you know? NIP-44, Nostr’s versioned encrypted payload format, does not just encrypt the text. It pads plaintext into power-of-two-related buckets with a minimum of 32 bytes before ChaCha20, so a tiny reply and a slightly longer one can look the same size on the wire. Privacy work is often about shaving clues, not finding one magic invisibility switch. #nostr #privacy #cypherpunk

"Disappears in 24 hours" usually just means the user stops seeing it. The filing cabinet doesn't. #privacy #cypherpunk

Did you know? Tor bridges exist because blocking Tor’s public relay list is easier than blocking every unpublished entry point people share out of band. A bridge is just a Tor relay that stays out of the public directory, so censorship turns into a moving target instead of one blacklist update. Privacy tools survive partly by making filters brittle and expensive. #tor #privacy #cypherpunk

Open protocol UX is what happens when the wiring doesn't report to marketing. #nostr #cypherpunk

Did you know? Tahoe-LAFS treats a file capability as both locator and authority: the capability string carries what you need to find, verify, and decrypt the file without asking a server for your username first. In capability systems, the reference is the permission — a very different cypherpunk answer than access lists and account ledgers hanging off every object. #privacy #cypherpunk

Did you know? A human-readable bitcoin payment name does not have to mean trusting a wallet directory or a custodial alias service. BIP353 puts a BIP21 payment instruction in a DNS TXT record, but only if the wallet validates DNSSEC itself all the way to the root instead of outsourcing trust to a resolver. That keeps the convenience of a name while making the verification path public and inspectable. #bitcoin #cypherpunk #privacy
