Multisignature

Multisignature (multi-signature) is a digital signature scheme which allows a group of users to sign a single document. Usually, a multisignature algorithm produces a joint signature that is more compact than a collection of distinct signatures from all users. Multisignature (multi-signature) is a digital signature scheme which allows a group of users to sign a single document. Usually, a multisignature algorithm produces a joint signature that is more compact than a collection of distinct signatures from all users. Multisignature can be considered as generalization of both group and ring signatures. Multisignature adds additional security for cryptocurrency transactions.
