What is A Crack in The Firmament Restoring Soundness of The Orion Proof System and More about?

The document discusses the Orion proof system, a post-quantum zero-knowledge argument system that has faced soundness issues since its introduction. Despite improvements over previous systems, Orion remains unsound due to flaws in its challenge-response order, allowing for practical attacks. The authors propose a new polynomial commitment scheme, Scorpius, which aims to fix these issues while enhancing efficiency and maintaining linear time prover complexity.
