Acceptance criteria

Port test from Charon, should pass these tests

[emlautarom1]

Charon does not implement Frost itself but rather delegates to a third party library https://github.com/coinbase/kryptology/blob/v1.8.0/pkg/dkg/frost/README.md.

The Rust ecosystem does not provide an exact 1-1 matching library, and our current options are (in order of preference):

• https://github.com/ZcashFoundation/frost: A generic library with support for multiple curves (except BLS12-381). Audited and used by a large community (zcash)
• https://github.com/LIT-Protocol/lit-frost: An all-in-one library with support for multiple curves (except BLS12-381). Audited and used by a relatively small community.
• https://github.com/serai-dex/serai/blob/develop/crypto/frost/README.md: An internal module used by a DEX. Audited.
• https://github.com/mikelodder7/frost-dkg: A small, independent implementation with support for the required curves. Not audited, verified or tested in production.
