MuSig2: Simple Two-Round Schnorr Multi-Signatures

> we propose MuSig2, a novel and simple two-round multi-signature scheme variant of the MuSig scheme. Our scheme is the first multi-signature scheme that simultaneously i) is secure under concurrent signing sessions, ii) supports key aggregation, iii) outputs ordinary Schnorr signatures, iv) needs only two communication rounds, and v) has similar signer complexity as regular Schnorr signatures. Furthermore, our scheme is the first multi-signature scheme in the DL setting that supports preprocessing of all but one rounds, effectively enabling a non-interactive signing process, without forgoing security under concurrent sessions.
