Definition ∞ Multi-Sig Security, or multi-signature security, requires multiple private keys to authorize a single transaction or access a digital wallet. Instead of a single key, a predefined number of keys from a set must sign off on any action. This cryptographic technique significantly enhances the security of digital assets by eliminating single points of failure. It offers a robust defense against unauthorized access.
Context ∞ Multi-Sig Security is a widely adopted practice in the cryptocurrency space, particularly for institutional holdings, decentralized autonomous organizations (DAOs), and secure corporate treasuries. News reports often highlight its implementation in safeguarding large pools of digital assets from theft or accidental loss. Its increasing use reflects a growing emphasis on advanced security protocols within the industry.
