Acknowledgment

We're very grateful towards the following organizations, projects and people:

  • the Project Oak maintainers for making Rust Verifications Tools, a dual-licensed open-source project (MIT / Apache).
    The RVT tools allowed us to integrate with industrial-grade verification tools in a very effective way.
  • the KLEE Symbolic Execution Engine maintainers
  • the Rust community at large
  • All members of the NGI-Ledger Consortium for accompanying us
