Context

Blockchain technology, despite its promise of decentralization and immutability, faces significant challenges in guaranteeing the correctness and security of its complex components, such as smart contracts and consensus protocols. This is due to the difficulty of manually identifying subtle vulnerabilities and ensuring intended behavior in distributed, adversarial environments. Existing approaches often rely on empirical testing, which cannot provide exhaustive guarantees for critical systems.
