A brief overview of the formal specification landscape

The seL4 microkernel is currently the only kernel that has been fully formally verified. In general, the increased interest in ensuring the security of a kernel's code results from its important role in the entire…

MoonBit 0.9 introduces formal verification for AI-native workflows, enabling AI systems to generate code that is not just functional, but provably correct.

VeriTile embeds Triton in Lean 4 for kernel verification, with explicit semantics, mathematical specifications, and proof generation using agents.

Autoformalization is the process of automatically translating from natural language mathematics to formal specifications and proofs. A successful autoformalization system could advance the fields of formal…

<p>Abstract: “Secure compilation is a discipline aimed at developing compilers that preserve the security properties of the source programs they take as input in the target programs they produce as output. This discipline is broad in scope, targeting languages with a variety of features (including objects, higher-order functions, dynamic memory allocation, call/cc, concurrency) and employing a range of different techniques to ensure that source- level security is preserved at the target level. This article provides a survey of the existing literature on formal approaches to secure compilation with a focus on those that prove fully abstract compilation, which has been the criterion adopted by much of the literature thus far. This article then describes the formal techniques employed to prove secure compilation in existing work, introducing relevant terminology, and discussing the merits and limitations of each work. Finally, this article discusses open challenges and possible directions for future work in secure compilation.”</p>

Solus Linux now allows AI-assisted code contributions under strict disclosure, testing, and accountability requirements.

Proof assistants are introduced through their hardest applications, so people assume opening one means a large project. A four-state Agda specification, compiled and used as the test oracle for Go code, shows how small…
