Distributed Cryptography

Definition ∞ Distributed cryptography involves cryptographic operations that are performed across multiple nodes in a network rather than on a single machine. This approach distributes computational load and enhances security by preventing single points of compromise. It is a foundational element for many decentralized systems, ensuring that cryptographic functions operate reliably without central oversight.
Context ∞ Distributed cryptography is a key enabler for many advanced features in blockchain and cryptocurrency networks, including secure multi-party computation and threshold cryptography. Current discourse often centers on its role in facilitating more private transactions, secure governance mechanisms, and scalable consensus protocols, directly impacting the security and functionality of next-generation digital asset platforms.
