Good morning again.
I might be retareded but I think ChillDKG proposed for establishing a FROST key could be done using nostr keys as the "host key pair"
"Instead of performing an out-of-band check as the last step of the DKG, ChillDKG relies on a more direct approach: ChillDKG is a wrapper around EncPedPop, which instantiates the required equality check protocol with a concrete in-band protocol CertEq. CertEq assumes that each participant holds a long-term key pair of a signature scheme, called the host key pair. ChillDKG repurposes the host key pairs by passing them down as ECDH key pairs to EncPedPop.5
ChillDKG requires that all participants have authentic copies of the other participants' host public keys.6 Authenticity of the host public keys can be verified through pairwise out-of-band comparisons between every pair of participants. This verification can occur at any time before the DKG session is finalized, in particular before the start of the session."
