So, let’s cut our teeth on the mighty Schnorr signature. This method has the great advantage that we can have multiple signers to a message or a transaction, and end up with a single signature for all the signers. It is now being used in Bitcoin transactions so that we have an efficient signature for a transaction that involves multiple entities.
