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

Authors: Barnabas Arvay, Thi Thu Ha Doan, and Peter Thiemann

Published in: LIPIcs, Volume 313, 38th European Conference on Object-Oriented Programming (ECOOP 2024)

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.

Towards Contract Modules for the Tezos Blockchain (Short Paper)

Authors: Thi Thu Ha Doan and Peter Thiemann

Published in: OASIcs, Volume 95, 3rd International Workshop on Formal Methods for Blockchains (FMBC 2021)

Abstract
Programmatic interaction with a blockchain is often clumsy. Many interfaces handle only loosely structured data, often in JSON format, that is inconvenient to handle and offers few guarantees. Contract modules provide a statically checked interface to interact with contracts on the Tezos blockchain. A module specification provides all types as well as information about potential failure conditions of the contract. The specification is checked against the contract implementation using symbolic execution. An OCaml module is generated that contains a function for each entry point of the contract. The types of these functions fully describe the interface including the failure conditions and guarantee type-safe and sometimes fail-safe invocation of the contract on the blockchain.

Model Checking of Robot Gathering

Authors: Ha Thi Thu Doan, François Bonnet, and Kazuhiro Ogata

Published in: LIPIcs, Volume 95, 21st International Conference on Principles of Distributed Systems (OPODIS 2017)

Abstract
Recent advances in distributed computing highlight models and algorithms for autonomous mo- bile robots that self-organize and cooperate together in order to solve a global objective. As results, a large number of algorithms have been proposed. These algorithms are given together with proofs to assess their correctness. However, those proofs are informal, which are error prone. This paper presents our study on formal verification of mobile robot algorithms. We first propose a formal model for mobile robot algorithms on anonymous ring shape network under multiplicity and asynchrony assumptions. We specify this formal model in Maude, a specification and pro- gramming language based on rewriting logic. We then use its model checker to formally verify an algorithm for robot gathering problem on ring enjoys some desired properties. As the result of the model checking, counterexamples have been found. We detect the sources of some unforeseen design errors. We, furthermore, give our interpretations of these errors.
