StateSync-GKR: Design and Evaluation of a Reusable Sparse GKR Engine

Authenticated state transitions need proof engines that conserve memory, avoid repeated setup, and preserve request semantics across parallel execution. We present StateSync-GKR, a reusable Rust sumcheck/GKR core with a sparse-Merkle frontend, and connect its design mechanisms to controlled measurements. Sparse layer r...

StateSync-GKR: Machine-Checking the Trust Chain from Sparse-Merkle State Transitions to GKR Verification

GKR soundness bounds false output claims about arithmetic circuits, but an application also needs assurance that its circuit encodes the intended state transition. We machine-check this connection for sparse-Merkle membership, non-membership, and update in Isabelle/HOL. A compiler model relates circuit acceptance to tr...
