Definition ∞ A Weighted Threshold Scheme is a cryptographic method where an action requires a collective approval based on the sum of “weights” assigned to participating parties, rather than a simple count. Each participant holds a specific weight, and a predefined threshold weight must be met for the action to proceed. This permits nuanced control, allowing some participants to possess greater influence than others. It offers flexible authorization mechanisms.
Context ∞ In the digital asset space, weighted threshold schemes find application in multi-signature wallets, decentralized autonomous organization (DAO) governance, and secure key management systems. News often reports on DAO voting structures or multi-sig wallet configurations that use such schemes to control access to significant treasuries or protocol upgrades. This approach enhances security and governance by distributing authority based on predefined influence levels.
