Introducing Noosphere, an implementation of ROAST for Dart

[MatthewLM]

Noosphere is an open-source ROAST server and client for Taproot threshold Schnorr signatures. It is built upon the frost-secp256k1-tr crate, written in Dart and available for Flutter.

Noosphere includes DKG and signing with support for Taproot transactions. The software is provided "as-is". Review and feedback is very welcome!

The free service roast.host is available to create ROAST coordination servers.

The following packages are available:

• frosty: A Dart wrapper around the Rust library providing high-level FROST support for Taproot.
• frosty_flutter: A Flutter plugin that provides automated builds for Linux, Android, macOS and iOS. Windows is included but not tested.
• noosphere_roast_client: A library that provides a client for engaging as a participant in a FROST/ROAST group with a connection to a coordination server.
• noosphere_roast_server: Provides both a library and a program for running ROAST coordination servers.
