Confium Playground — zero-install DKG + sign + verify

2-of-3 threshold ECDSA

Generate 3 shares of a single ECDSA-P256 key. Sign a message with any 2 of them. The third share isn't needed.

Message

Append entries to a Merkle tree. Generate inclusion proofs. Verify them.

Entry to append

Verify a composite signature — both Ed25519 and ECDSA-P256 components must pass. Useful for post-quantum migration where you bridge classical + PQ.

Message

See how DP noise scales with the privacy budget ε. Smaller ε = more noise = more privacy.

True value ε (privacy budget) 0.5 Sensitivity
