Multisignature
Multisignature 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. Multisig crypto wallets require all parties involved in the creation of this type of wallet to agree before any transaction can occur.
