@ -15,6 +15,9 @@ This crate provides a flexible rust implementation of [MuSig2](https://eprint.ia
|
||||
|
||||
MuSig2 allows groups of mutually distrusting parties to cooperatively sign data and aggregate their signatures into a single aggregated signature which is indistinguishable from a signature made by a single private key. The group collectively controls an _aggregated public key_ which can only create signatures if everyone in the group cooperates (AKA an N-of-N multisignature scheme). MuSig2 is optimized to support secure signature aggregation with only **two round-trips of network communication.**
