Title:
Efficient Layered Circuit for Verification of SHA3 Merkle Tree

Authors: CHANGCHANG DING, Zheming Fu

Abstract:

We present an efficient layered circuit design for SHA3-256 Merkle tree verification, suitable for a GKR proof system, that achieves logarithmic verification and proof size. We demonstrate how to compute the predicate functions for our circuit in O(\log n) time to ensure logarithmic verification and provide GKR benchmarks for our circuit.
