Aggregate Signature Scheme

Definition ∞ An aggregate signature scheme permits multiple distinct signatures from various signers on different messages to be condensed into a single, compact signature. This single aggregate signature verifies the validity of all individual signatures and their corresponding messages efficiently. The method significantly reduces data size and verification overhead, which is particularly beneficial in blockchain systems with numerous transactions. This cryptographic primitive enhances scalability and privacy by obscuring individual transaction details within the collective proof.
Context ∞ Aggregate signature schemes are a subject of ongoing research and implementation within various blockchain protocols aiming to boost transaction throughput and minimize storage requirements. Discussions often revolve around specific cryptographic constructions like BLS signatures and their resistance to various attack vectors. Their adoption is a critical factor for the long-term viability and efficiency of large-scale decentralized networks, offering a pathway to handle increasing transaction volumes without compromising security.
