Cloned voices can beg. They can cry. They can sound exactly like your kid. What they can't do is sign a phrase with your kid's key. zikora turns a moment of doubt into a signed answer.
zikora is deliberately small. Each person holds an Ed25519 key on their own device; a challenge is a fresh phrase; verification is a signature check. There's nothing to phish, nothing to reuse, and nobody in the middle.
A forged signature is rejected. Yesterday's proof is useless. And doubt never quietly becomes trust — challenges expire in minutes, visibly.
Type their name. zikora mints a fresh phrase for this call and this call only — never reused, gone in minutes.
Read the phrase to your caller. Anyone can hear it; only one person in the world can answer it.
Their device signs the phrase with a key only they hold. Your screen flips to verified — or it doesn't, and now you know.
A safe word you must whisper can be stolen. zikora's phrase is said out loud to the fake and the real alike — and only one of them can answer.
Five minutes at the dinner table: everyone gets a key, everyone learns the ritual. The next strange phone call gets an answer instead of a knot in your stomach.
