Module roast

Roast Module Documentation

The Roast module implements a state machine for managing the Robust Online Asynchronous Schnorr Threshold (ROAST) protocol. This protocol allows a distributed set of signers to collaboratively generate Schnorr signatures in a secure and robust manner, ensuring that the signature process can continue even if some participants fail to respond or act maliciously.

Overview

The main components of the Roast module include:

• ‘RoastSigner’: Manages the signing process for a single participant.
• ‘RoastCoordinator’: Coordinates the signing process, ensuring that enough participants have committed to generate a signature.
• ‘RoastSession’: Manages a single signing session, tracking commitments and signature shares.
• ‘Roast’: The main state machine that brings together the RoastSigner and RoastCoordinator to manage the overall ROAST protocol.
