A Dynamic Logic for Symbolic Execution for the Smart Contract Programming Language Michelson

Abstract

Verification of smart contracts is an important topic in the context of blockchain technology. We study an approach to verification that is based on symbolic execution. As a formal basis for symbolic execution, we design a dynamic logic for Michelson, the smart contract language of the Tezos blockchain, and prove its soundness in the proof assistant Agda. Towards the soundness proof we formalize the concrete semantics as well as its symbolic counterpart in a unified setting. The logic encompasses single contract runs as well as inter-contract runs chained in a single transaction.
