There are various theoretically-efficient constructions of public-randomness (i.e., Arthur-Merlin type) Zero-Knowledge Succinct Arguments of Knowledge in the random oracle model, for computations-verification (also known as verifiable-computation and computational-integrity). Those constructions could be used to solve many real world problems; Unfortunately, reducing those fabulous theoretical systems to broadly-adaptable implementations is a challenging task. This talk surveys our efforts to construct such systems with concrete (rather than asymptotic) efficiency. This requires improving both theory and practice in a concerted effort, and led to an efficient proof-of-concept implementation supported by new theoretical results and which leads to interesting theoretical and practical questions. This is a joint work with Eli Ben-Sasson, Iddo Ben-Tov, and Yinon Horesh.
