“…On the other hand, in model-based verification approaches, a formal model of the smart contract is specified separately from the implementation. Given such a formal model and the implementation, two kinds of verification are performed: (1) does the formal model satisfy the desired properties [29,17]? (2) is the implementation consistent with the formal model [19]?…”

Smart contracts manage a large number of digital assets nowadays. Bugs in these contracts have led to significant financial loss. Verifying the correctness of smart contracts is therefore an important task. This paper presents a safety verification tool DCV that targets declarative smart contracts written in DeCon, a logic-based domainspecific language for smart contract implementation and specification. DCV is sound and fully automatic. It proves safety properties by mathematical induction and can automatically infer inductive invariants without annotations from the developer. Our evaluation shows that DCV is effective in verifying smart contracts adapted from public repositories, and can verify contracts not supported by other tools. Furthermore, DCV significantly outperforms baseline tools in verification time.
