As far as I know, this is the first formal spec for Miniscript. I also considered using the K framework [1] for the task (it would also give the parser out of the box), but at the time it did not have the reference documentation, only tutorials on their site. It seems that they have published the new site, with more documentation. I am satisfied with how Alloy spec turned out, though - in my opinion, the node definitions in the spec are very readable.

Re: [bitcoin-dev] Formal specification of Miniscript in Alloy
Thanks for this! I can't comment on the correctness of your implementation, but I really appreciate the idea and effort. By chance, did you come across any other spec definitions in alternate formal grammars? -Clark On Wed, Nov 25, 2020 at 5:35 AM Dmitry Petukhov via bitcoin-dev < bitcoin-dev@lists.linuxfoundation.org> wrote: > I have created a formal specification of Miniscript [1] using > the specification language of Alloy analyzer [2] > > Link: https://github.com/dgpv/miniscript-alloy-spec > > Possible uses for the spec: > > - Implementing Miniscript libraries, as additional reference that might > be easier to navigate than prose spec > > - Generating test cases for implementations, although currently this > will be a manual process due to the tools limitation (can be overcome > with GUI automation) > > - Checking the implementation against the spec, by writing a program > that would generate Alloy .als files from the data structures of the > implementation, and then checking these files in Alloy > > - Extending or amending Miniscript, if the need arise.

[bitcoin-dev] Formal specification of Miniscript in Alloy
I have created a formal specification of Miniscript [1] using the specification language of Alloy analyzer [2] Link: https://github.com/dgpv/miniscript-alloy-spec Possible uses for the spec: - Implementing Miniscript libraries, as additional reference that might be easier to navigate than prose spec - Generating test cases for implementations, although currently this will be a manual process due to the tools limitation (can be overcome with GUI automation) - Checking the implementation against the spec, by writing a program that would generate Alloy .als files from the data structures of the implementation, and then checking these files in Alloy - Extending or amending Miniscript, if the need arise. Having extenstions and changes checked (with bounds) against a spec should help catch inconsistencies - Exploring the properties of Miniscript If you have an interest in Miniscript, please consider looking at the spec and share your ideas. The spec may contain mistakes, as it was not yet checked against any implementation, it was only checked for consistency using its own predicates, with the scope of up to 8 nodes. If you notice a mistake or inconsistency, please submit an issue on github (or communicate this in other ways) [1] http://bitcoin.sipa.be/miniscript/ [2] https://alloytools.org/ ___ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
