Fast and Reliable Formal Verification of Smart Contracts with the Move Prover

Nov 30, 2022

Abstract

The Move Prover (MVP) is a formal verifier forsmart contracts written In the Move programming language. MVP has an expressivespecification language, and is fast and reliable enough that it can be runroutinely by developers and in integration testing. Besides the simplicity ofsmart contracts and the Move language, three implementation approaches areresponsible for the practicality of MVP: (1) an alias-free memory model, (2)fine-grained invariant checking, and (3) monomorphization. The entirety of theMove code for the Diem blockchain has been extensively specified and can becompletely verified by MVP in a few minutes. Changes in the Diem framework mustbe successfully verified before being integrated into the open sourcerepository on GitHub.
