Abstract



The Move Prover (MVP) is a formal verifier for smart contracts written In the Move programming language. MVP has an expressive specification language, and is fast and reliable enough that it can be run routinely by developers and in integration testing. Besides the simplicity of smart contracts and the Move language, three implementation approaches are responsible for the practicality of MVP: (1) an alias-free memory model, (2)fine-grained invariant checking, and (3) monomorphization. The entirety of the Move code for the Diem blockchain has been extensively specified and can be completely verified by MVP in a few minutes. Changes in the Diem framework must be successfully verified before being integrated into the open source repository on GitHub.
