Systems and methods for formal verification of programs. The systems and methods provide a new game-theoretical, strategy-based compositional semantic model for concurrency, a set of formal linking theorems for composing multithreaded and multicore concurrent layers, and a compiler that supports certified thread-safe compilation and linking. Verification of an overlay interface can include determining an intermediate strategy for a primitive operation running on an underlay interface and refining that intermediate strategy to a strategy running on the overlay interface by applying a vertical and a horizontal composition rule. The refined strategy can then be composed with compatible strategies running on the overlay interface according to a parallel composition rule. Strategies may be compatible when rely conditions imposed by each strategy satisfy guarantees provided by the other strategies. The system and method of formal verification can be applied to formal verification of smart contracts.
