QCAP: A Bitcoin-Native Quantum Canary Alert

The discussion delves into the intricacies of cryptographic protocols, specifically analyzing how certain theoretical models can be practically applied. A notable point of reference is the 2022 DLEQAG paper, which examines scenarios where the bit length of a secret is significantly smaller than that of one of two groups involved. It suggests methodologies to adapt this situation for broader applications. Additionally, the paper references an approach detailed in a Monero Research Lab note, attributed to Poelstra, which employs a vanilla sigma protocol. Although this method might not be efficient in all cases, it is deemed suitable within the specific constraints discussed (MRL note with an algo attributed to Poelstra).

The email also touches upon the concept of multiparty secret generation algorithms, hinting at various possible implementations without specifying a definitive choice. The Distributed Key Generation (DKG) template, similar to that used in FROST, is mentioned as an apt framework, particularly because it facilitates the Proof of Knowledge (PoK) of contributions without necessitating threshold schemes. This could potentially allow for extensive participation in cryptographic ceremonies, such as the powers of tau, accommodating hundreds to thousands of participants, thus optimizing the engineering considerations for large-scale secure setups.
