Welcome to the resource topic for 2024/1402

Title:
A Recursive zk-based State Update System

Authors: Daniel Bloom, Sai Deng

Abstract:

This paper introduces a ZKP (zero-knowledge proof) based state update system, where each block contains a SNARK proof aggregated from the user generated zkVM (zero knowledge virtual machine) proofs. It enables users to generate state update proofs in their local machines, contributing to a secure, decentralized verification process. Our main contribution in this paper, the recursive proofs system, addresses scalability by recursively verifying user proofs and aggregating them in a hierarchical tree structure up to a root proof, serving as a block proof. The proposed solution advances current blockchain paradigms by offering efficient recursive verification through ZKP, enhancing security and reducing computational load.
