To achieve trust and continuity in the smart contracts-based business process execution, the
verification of such smart contracts is mandatory. A blockchain-based smart contract should …

A smart contract is hard to patch for bugs once it is deployed, irrespective of the money it
holds. A recent bug caused losses worth around $50 million of cryptocurrency. We present …

Smart contracts---stateful executable objects hosted on blockchains like Ethereum---carry
billions of dollars worth of coins and cannot be updated once deployed. We present a new …

In the recent years, the blockchain (BC) technology has been used in various applications
ranging from financial sector to healthcare sector. Moreover, develo** BC-based solutions …

Automatic program verification and symbolic model checking tools interface with theorem
proving technologies that check satisfiability of formulas. A theme pursued in the past years …

We present VERISMART, a highly precise verifier for ensuring arithmetic safety of Ethereum
smart contracts. Writing safe smart contracts without unintended behavior is critically …

Smart contract security is an emerging research area that deals with security issues arising
from the execution of smart contracts in a blockchain system. Generally, a smart contract is a …

Reentrancy bugs, one of the most severe vulnerabilities in smart contracts, have caused
huge financial loss in recent years. Researchers have proposed many approaches to …

We present EzPC, a secure two-party computation (2PC) framework that generates efficient
2PC protocols from high-level, easy-to-write programs. EzPC provides formal correctness …

Reduction to satisfiability of constrained Horn clauses (CHCs) is a widely studied approach
to automated program verification. Current CHC-based methods, however, do not work very …
