Clookup - Composite Function based Lookup Argument

Duration: 00:15:16

Speaker: Wanseob Lim

Type: Talk

Expertise: Expert

Event: Devcon

Date: Nov 2024

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.
