By means of an interactive scheme such as [https://eprint.iacr.org/2020/1261.pdf MuSig2] ([[bip-0327.mediawiki|BIP327]]), participants can aggregate their public keys into a single public key which they can jointly sign for. This allows ''n''-of-''n'' multisignatures which, from a verifier's perspective, are no different from ordinary signatures, giving improved privacy and efficiency versus ''CHECKMULTISIG'' or other means.

Moreover, Schnorr signatures are compatible with [https://en.wikipedia.org/wiki/Distributed_key_generation distributed key generation], which enables interactive threshold signatures schemes, e.g., the schemes described by [http://cacr.uwaterloo.ca/techreports/2001/corr2001-13.ps Stinson and Strobl (2001)], [https://link.springer.com/content/pdf/10.1007/s00145-006-0347-3.pdf Gennaro, Jarecki, Krawczyk, and Rabin (2007)], [https://eprint.iacr.org/2020/852.pdf Komlo and Goldberg (2020)], or [https://eprint.iacr.org/2023/899.pdf Chu, Gerhart, Ruffing, and Schröder (2023)]. These protocols make it possible to realize ''k''-of-''n'' threshold signatures, which ensure that any subset of size ''k'' of the set of ''n'' signers can sign but no subset of size less than ''k'' can produce a valid Schnorr signature.
