Resources to help you trust — and verify — Blink.
Browse our whitepapers, threat model, honest roadmap, and support resources. Blink is private by design and fast by default.
Security whitepaper
Learn how Blink encrypts messages and media using AES-256-GCM authenticated encryption, ECDH P-256 key agreement, and HKDF-SHA256 key derivation, with keys that rotate every seven days for forward secrecy.
Threat model
We spell out what we defend against and what we don't: servers that only ever hold ciphertext, encryption keys that stay on your device, a duress wipe, and screen protection.
Honest roadmap
