Definition ∞ “STARK to SNARK” refers to the process of converting a proof generated by a Scalable Transparent Argument of Knowledge (STARK) system into a proof verifiable by a Succinct Non-Interactive Argument of Knowledge (SNARK) system. This conversion is performed to combine the scalability benefits of STARKs with the extremely compact verification size of SNARKs. STARKs offer efficient proving for large computations, while SNARKs provide very small on-chain verification costs. The combination aims for optimal performance across both metrics.
Context ∞ News in the zero-knowledge proof domain frequently discusses “STARK to SNARK” recursive proof composition as a cutting-edge technique for blockchain scaling. The primary goal is to achieve both fast off-chain proof generation and minimal on-chain verification expenses. Debates involve the computational overhead of the conversion process and the specific constructions used to bridge these two powerful proof systems. This approach is critical for building highly scalable and efficient layer-2 solutions.
