QML GUI

Q&A

Current GUI and QML progress seems slow?
Code review / build system involvement? Will there be a test suite?
- Test suite yes, No fuzzing planned
Why not RPC based?
- RPC not currently capable of building this UI on top of
Is there a QML dependency graph?
- More dependencies required for sure
- May have to abandon depends approach
Blocking calls historically an issue
- A consideration, but more to talk about here

Discussion

If other wallets and GUIs are having issues building on Core, we should address that
- Dog fooding within the current GUI could be a good way to discover that as opposed to Core GUI having privileged access
- Sparrow, Specter are not trying to be Bitcoin Core GUIs they are external wallets.
Discussions about nuances around Bitcoin Core GUI frontend vs being a wallet frontend
Core GUI is mostly wallet, few node UI features
Considerations of additional work for the build system contributors
Examples of the project’s toolchain bumps being held back by qt, dependencies
- QML potentially worse. C++20 problem for android
- If you have a GUI at all, there will be dependencies
Maybe use Bitcoin Core master as a github sub tree project dependency
- Separate release schedules between GUI and Core
  - Do most users run on Window/Mac + GUI or Linux variants?
    - If GUI users then separate release processes, that might hold up new network features
- Or, could pull in Core build via guix build processes
- Is making Bitcoin Core a dependency of the GUI a good idea?
