FROST (EdDSA) Playground

FROST is a threshold signature protocol that allows a group to jointly create a valid EdDSA/Schnorr signature — without ever revealing the private key. This simulation shows how shares are distributed and then used to "sign" together.

How it works (simplified)

Generate a private key and split it into multiple shares.
Participants each hold a share. No one knows the full key.
At signing time, participants collaborate to produce a valid signature.

Why FROST matters

Used in modern threshold wallets and MPC signing systems
Efficient: only 1–2 rounds of communication
Secure against rogue key attacks and faulty signers
