Multi-signatures enable a group of signers to jointly generate a short and efficiently verifiable signature on a common message. They are commonly used in proof-of-stake and permissioned blockchains, ...
Multi-signatures allow a group of signers to jointly sign a message in a compact and efficiently verifiable signature, ideally independent of the number of signers in the group. We present the first p...
We construct new multi-signature schemes that provide new functionality. Our schemes are designed to reduce the size of the Bitcoin blockchain, but are useful in many other settings where multi-signat...

We describe a new Schnorr-based multi-signature scheme (i.e., a protocol which allows a group of signers to produce a short, joint signature on a common message), provably secure in the plain public-k...
