An Rust implementation of FROST: Flexible Round-Optimised Schnorr Threshold signatures using the Ristretto group

FROST

A Rust implementation of FROST: Flexible Round-Optimised Schnorr Threshold signatures by Chelsea Komlo and Ian Goldberg.

Usage

Please see the documentation for usage examples.

Note on no_std usage

Most of this crate is no_std compliant, however, the current implementation uses HashMaps for the signature creation and aggregation protocols, and thus requires the standard library.

WARNING

This code is likely not stable. The author is working with the paper authors on an RFC which, if/when adopted, will allow us to stabilise this codebase. Until then, the structure and construction of these signatures, as well as wireformats for several types which must be sent between signing parties, may change in incompatible ways.
