In December 2023, we shared an Aptos-related bug report with the Wormhole Bug Bounty Program. We were impressed at Wormhole’s quick and effective resolution of the issue. A patch resolved the issue within 3.5 hours of the initial report.

Understanding ZK verification is crucial for blockchain integrity. It’s a complex process that CertiK is pioneering to ensure that every step in a ZK VM Chain’s execution is mathematically verified to be secure and correct. What Is It? ZK instructions are like precise mathematical puzzles. Each one must fit perfectly to maintain a secure ZK Chain. If even one instruction is off, it’s akin to a missing piece that could compromise the entire system. What Does It Mean? When executing a ZK instruction, the focus is on preserving a valid state within the ZK VM. CertiK ensures each operation transitions accurately to a predetermined, secure state, affirming the system’s integrity. What Does It Take? To achieve this, we have to tackle three things: stack memory consistency, arithmetic precision, and execution flow accuracy. Each is a commitment to meticulous scrutiny, ensuring that ZK proofs stand up to the highest assurance level.
