FACTum Studio 2.0

My colleague Habtom K. Gidey was presenting our second release of FACTum Studio at the 16th International Conference on Formal Aspects of Component Software taking place these days in Amsterdam.

The new version now supports the modeling of behavior for component types in terms of finite-state machines and the verification of corresponding contracts using model checking.

Soon we will provide a preprint of our FACS paper which describes all the extensions in detail and demonstrates them by means of a running example.

FMBC: List of Accepted Papers

Thanks to all the authors which sent their papers to FMBC: the 1st Workshop on Formal Methods for Blockchains @ FM.

Competition was fierce: we received 20 high-quality submissions out of which we accepted seven regular papers and three additional short papers.

The list of accepted papers is available at: https://sites.google.com/view/fmbc/program

Congratulations to all the authors of accepted papers!

We are looking forward to meeting all of you in October for a day of inspiring discussions on Formal Methods for Blockchains!

Paper accepted @ FM 2019 – APML: An Architecture Proof Modeling Language

In this paper, accepted for presentation at the 23rd International Symposium on Formal Methods, we introduce APML, a sound and complete language to sketch proofs for composition of FACTum contracts in a notation similar to Message Sequence Charts. Moreover, we provide an algorithm to generate Isabelle/Isar proofs out of an APML sketch.

The language is implemented in FACTum Studio which supports the user in the development of correct APML proofs. In addition we also implemented the algorithm in FACTum Studio which allows a user to generate Isabelle/Isar proofs out of an APML sketch.
