dc.description.abstract
PLONK is a zk-SNARK system by Gabizon, Williamson, and Ciobotaru with proofs of constant size (0.5 KB) and sublinear verification time. Its setup is circuit-independent supporting proofs of arbitrary statements up to a certain size bound.
Although deployed in several real-world applications, PLONK’s zero-knowledge property had only been argued informally. Consequently, we were able to find and fix a vulnerability in its original specification, leading to an update of PLONK in eprint version 20220629:105924.
In this work, we construct a simulator for the patched version of PLONK and prove that it achieves statistical zero knowledge. Furthermore, we give an attack on the previous version of PLONK showing that it does not even satisfy the weaker notion of (statistical) witness indistinguishability.
