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.
Context ∞ The current discourse surrounding multi-signature wallets is largely focused on their application for institutional asset management and the secure storage of significant digital asset holdings. Discussions often highlight the trade-offs between security and usability, particularly in scenarios requiring rapid transaction authorization. Future developments are expected to involve the refinement of user interfaces for multi-signature management and the integration of more advanced threshold signature schemes.
