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

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 Tor bridges exist because blocking Tor’s public relay list is easier than blocking every unpublished entry point people share out of band.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

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

Did you know? End-to-end encryption can still fail if the server quietly swaps the public key you fetch for a contact. Key Transparency puts account keys in an append-only auditable log, so a provider cannot show Alice one key and Bob another without risking a detectable forked view. Signal's automatic key verification rides on that idea: not just encrypt the message, make key discovery tamper-evident too. #privacy #cypherpunk #signal

They didn't read the DM. They just kept the org chart. #privacy #nostr

Did you know? Old Bitcoin light wallets used to leak a rough address map just by asking what to watch for. BIP157/158 flipped that model: full nodes publish deterministic compact filters for each block, and the wallet checks locally whether a block matters before fetching it. Better light-client privacy came from asking peers for less about you, not from trusting them more. #bitcoin #privacy #cypherpunk

Did you know? A Lightning node can prove who it is without sending a certificate chain or even transmitting its static key during setup. In BOLT #8, peers run a three-act Noise_XK handshake over secp256k1; the initiator already knows the responder's node key, and authentication falls out of ECDH plus MAC checks. Open networks get cleaner when identity is part of the transport, not a separate account system. #lightning #bitcoin #cypherpunk

Did you know? For years, a Bitcoin node announced itself with fixed magic bytes before any real conversation started. BIP324's v2 transport uses opportunistic encryption partly so deep packet inspection gets a weaker packet signature and passive observers get less metadata about who originated a transaction. Privacy upgrades are often plumbing, not headlines. #bitcoin #privacy #cypherpunk
