Formal verification of Move programs for the Libra blockchain

Fields Institute

David Dill, Novi Research

Blockchain Research Seminar Series

http://www.fields.utoronto.ca/activities/20-21/blockchain-research-seminar-series

Abstract: The Libra blockchain, which was initiated in 2018 by Facebook, includes a novel programming language called Move for implementing smart contracts. The correctness of Move programs is especially important because the blockchain will host large amounts of assets, those assets are managed by smart contracts, and because there is a history of large losses on other blockchains because of bugs in smart contracts. The Move language is designed to be as safe as we can make it, and it is accompanied by a formal specification and automatic verification tool, called the Move Prover. A project to specify and formally verify as many important properties of the Move standard library is now well underway.

This talk will be about the goals of the project and the most interesting insights we've had as of the time of the presentation. The entire blockchain implementation, including the Move language, virtual machine, the Move Prover, and near-final various Move modules are available on http://github.com/libra
