The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The proposed model enables verification of knowledge of the secret key without revealing it, with proof generation and verification times in the millisecond range and constant proof size of approximately 0.5 KB under 256-bit security, making it suitable for mobile and low-resource systems.

C2weakest assumption

The security and practicality claims rest on the assumption that the Schnorr protocol combined with nonce and timestamp mechanisms provides sufficient protection against replay and other attacks in real deployments, as the abstract provides no formal security reduction or implementation details beyond simulation timing.

C3one line summary

A Schnorr-based zero-knowledge protocol embeds constant-size proofs in QR codes for replay-resistant authentication with millisecond generation and verification times.
