Kani is a formal verification tool and model checker for Rust. It functions as a bit-precise static analyzer that mathematically proves the correctness and memory safety of code by exhaustively analyzing program states to identify undefined behavior, panics, and logic errors. The tool identifies bugs by producing concrete counterexamples when program assertions or safety contracts are violated. It enables the definition of function contracts through preconditions and postconditions to verify that inputs and outputs match expected behavior. The system provides capabilities for Rust program an

Ikos is a formal verification suite and static analysis framework designed to prove the absence of undefined behaviors and runtime errors in C and C++ source code. It functions as an abstract interpretation tool that approximates program execution to identify potential crashes and software defects. The system utilizes a compiler front-end to translate source code into a specialized abstract representation. This process decouples language parsing from the analysis logic, allowing the framework to perform deep program analysis via a formal verification system. The toolkit covers several analys

Lean 4 is a functional programming language and interactive proof assistant used to formalize mathematics and verify software correctness. It functions as a dependent type theorem prover and a formal verification tool that allows users to construct mathematical proofs and ensure program correctness. Additionally, it serves as a logic-based source for generating verified datasets used to train and benchmark artificial intelligence reasoning systems. The system distinguishes itself through a small-kernel verification model, where all proofs are verified by a trusted core of basic logical rules.
