Proof Composition

Definition ∞ Proof composition is a cryptographic technique that allows for the combination of multiple verifiable proofs into a single, more concise proof. This process is particularly relevant in zero-knowledge proof systems, where it enables the verification of complex computations through a singular, efficient proof. It is a key factor in enhancing the scalability and usability of privacy-preserving technologies.
Context ∞ The advancement of proof composition is a critical area of research for scaling solutions in blockchain and other privacy-preserving applications. Discussions frequently revolve around the efficiency of combining different types of proofs and the potential for compositional attacks. Future developments are expected to introduce more advanced compositional techniques that can handle a wider array of computational structures and further reduce verification overhead.
