Verifying functional properties of smart contracts using symbolic model-checking

Blog Article

We describe our efforts towards building a tool that automatically verify high-level functional properties of Ethereum smart contracts against its formal specification that can bar vac 7 somnus be given using four different methods: an invariant over contract state or three different types of trace properties.A model of runtime system, the source code of smart contract together with its specification is translated into SMT-solver formula and checked for counter example.We tested the method on simplified version of notorious TheDAO smart-contract, called MiniDAO.Our proof-of-concept tool was able to find a functional property violation of MiniDAO in just several seconds.We believe that the proposed method bullfrog plush is indeed useful and deserves deeper investigation.
