Threshold Cryptography

Definition ∞ A cryptographic system that requires a minimum number of participants (a threshold) to cooperate to perform a cryptographic operation, such as generating a key or signing a message. This approach enhances security by distributing sensitive operations across multiple parties, preventing single points of failure or compromise. It is fundamental for secure multi-party computation and key management in decentralized systems.
Context ∞ ‘Threshold Cryptography’ is frequently discussed in the context of securing digital asset wallets, multi-signature schemes, and decentralized autonomous organizations (DAOs). News often highlights its implementation in new protocols designed to bolster security and resilience against attacks. Its adoption is seen as a critical step in maturing the security infrastructure of the digital asset landscape.
