We've been wanting nested MuSig for a while now, so we can distribute Ark server keys and improve security. The problem is, it's specialized cryptographic work that we probably don't have within the team.
Jesse Posner (Vora founder) approached us with a solution: fund a grant for Beulah Evangelin to build it. Beulah's already contributing to secp256k1-zkp, just finished Chaincode Labs' secp256k1 workshop, and is perfect for the job.
So we're funding the grant. Jesse/Vora will provide ongoing mentorship. And Beulah's nested MuSig implementation will go into libsecp256k1-zkp as open source, so any project can use it. It's going to be particularly valuable for layer 2s, e.g., Vora needs it for their Lightning implementation too.
