Clookup - Composite Function based Lookup Argument
11-15, 15:30–15:50 (Asia/Bangkok), Stage 3

Presenting Clookup, a novel lookup protocol that enhances efficiency in verifiable computations. By using a composite function approach and multivariate polynomials within the sumcheck protocol, Clookup achieves optimal time complexity (O(m(m+n))) when processing (2^m) witness elements against a (2^n) table. This method eliminates the need to compute coefficient forms of composite functions.
