Proving-System Bugs Become a Distinct Rollup Risk
Soundness defects in zero-knowledge proving systems will keep surfacing as a risk class separate from smart-contract exploits, because validator re-execution — the fallback most rollups rely on — cannot catch them, forcing teams into embargoed disclosure timed to upgrades and pushing users toward proof-system diversity and escape hatches.

Why the conviction moved
- Aug 28Strengthened +6
Aztec core contributors disclosed a defect in the Alpha V5 proving system that could let an invalid transaction pass verification, found July 27 via internal AI-assisted auditing, and said they cannot determine whether it was exploited first. A soundness bug that verification itself would wave through, with no way to rule out prior exploitation, is precisely the failure class re-execution cannot catch and forces the embargoed-disclosure pattern the thesis describes.
- Aug 27Strengthened +7
Aztec core contributors disclosed a critical soundness flaw in the Alpha v5 proving system that would let an attacker construct a verifying proof for a transaction the network should reject, and say they cannot rule out prior exploitation. This is a direct instance of the thesis's failure mode: no re-execution fallback catches a false proof, and the uncertainty over prior use shows the class is undetectable after the fact.
