External Computation with Kontrol: Leveraging Foundry Execution for Formal Verification
This is the 3rd post of a three-part series about our recent Optimism engagement, in which we verified their pausability mechanism for L1 contracts. This post will explain a crucial feature we developed in Kontrol to verify the pausability mechanism in a realistic scenario. This new Kontrol feature allows loading a transcript of the effects of executing a function directly into proofs, which effectively means having a part of a Kontrol proof computed by Foundry!
Formal Verification Lore Intuitive Intro to Why We Can Prove Programs Correct
This article aims to provide context to formal verification, its different approaches, and why it can provide ultimate assurance of code correctness. Throughout the article, we provide insights into the field of formal verification and some of its components rather than explain how to use a specific tool. These insights should make it clearer to the newcomer to the field why we can claim mathematical rigorousness when we perform formal verification.
