Multi-Signature Wallet

Definition

A multi-signature wallet is a type of digital wallet that requires multiple private keys to authorize a transaction. It operates on a threshold system, meaning a predetermined number of signatures must be provided from a larger set of authorized signers. This configuration significantly enhances security by distributing control.
