I have creat= ed 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
=C2=A0 be easier to navigate than prose spec

- Generating test cases for implementations, although currently this
=C2=A0 will be a manual process due to the tools limitation (can be overcom= e
=C2=A0 with GUI automation)

- Checking the implementation against the spec, by writing a program
=C2=A0 that would generate Alloy .als files from the data structures of the=
=C2=A0 implementation, and then checking these files in Alloy

- Extending or amending Miniscript, if the need arise. Having
=C2=A0 extenstions and changes checked (with bounds) against a spec should<= br> =C2=A0 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)
