The ZF FROST suite consists of multiple crates. frost-core contains a generic implementation of the protocol, which can't be used directly without a concrete instantiation.

The ciphersuite crates (frost-ristretto255, frost-ed25519, frost-ed448, frost-p256, and frost-secp256k1) provide ciphersuites to use with frost-core, but also re-expose the frost-core functions without generics. If you will only use a single ciphersuite, then we recommend using those functions, and this tutorial will follow this approach. If you need to support multiple ciphersuites then feel free to use frost-core along with the ciphersuite types.

This tutorial will use the frost-ristretto255 crate, but changing to another ciphersuite should be a matter of simply changing the import.
