Multisig (Multisignature) is a technology that represents a special type of digital signature, with which users can join groups to sign a document. In order for a document or transaction to be signed, a pre-approved number of signatures of group members is required.
The advantages of multisig are:
- increased security level. The private keys required for signing are located on different devices and with different owners. It is not enough for an attacker to take possession of only one device to carry out a transaction;
- sharing of responsibilities. To make a transaction, it is necessary that several members of the group give their consent to this, and they use a personal digital signature.
