This will be part of a set of demos and a proof of concept application that uses the FROST libraries and reference implementation. The purpose of these demos is to:
This demo uses the (Ed25519, SHA-512) ciphersuite. The crate can be found [here](https://crates.io/crates/frost-ed25519).
## About FROST (Flexible Round-Optimised Schnorr Threshold signatures)
Unlike signatures in a single-party setting, threshold signatures require cooperation among a threshold number of signers, each holding a share of a common private key. The security of threshold
schemes in general assume that an adversary can corrupt strictly fewer than a threshold number of participants.
[Two-Round Threshold Schnorr Signatures with FROST](https://datatracker.ietf.org/doc/draft-irtf-cfrg-frost/) presents a variant of a Flexible Round-Optimized Schnorr Threshold (FROST) signature scheme originally defined in [FROST20](https://eprint.iacr.org/2020/852.pdf). FROST reduces network overhead during threshold
signing operations while employing a novel technique to protect against forgery attacks applicable to prior Schnorr-based threshold signature constructions. This variant of FROST requires two rounds to compute a signature, and implements signing efficiency improvements described by [Schnorr21](https://eprint.iacr.org/2021/1375.pdf). Single-round signing with FROST is not implemented here.
