Question about proof of pubkey consist

[b33ngo]

Has the protocol some features to proof that the public key participates in the multisig or that the multisig is created by a set of public keys?
There is some task to proof that some user is part of multisig or some group of users created a multisig. If it is possible how can it be done?

Hi thanks for your comment. Can you elaborate a bit more? That crate does not implement multisigs with a need to prove ownership of secret key to the published public if that is what you mean
