Have you tested to retrieve the whitepaper with a Spectrum connection?

Yeah, I tested. It's failing on mine maybe because I haven't added any device, but I feel it's close. Have a look

You don't need any device for this feature.

I don't understand why it does not recognise the fourth argument block hash despite adding it.

This can be simplified a lot. If you're unsure how to do that, please ask chatGPT to do it.

What do you mean by "recognise"? It would be cool to have a test here as well. Especially because you seem to do some kind of test and then claim that your test failed ("recognise it"). For some stuff we could do integration-tests. E.g. this one is imho a great candidate.
Have a look here getting an idea how this could look like to do tests on the mainchain:

• Understand how fixtures in pytest work
• create a pytest plugin like this: https://github.com/k9ert/specterext-taxtheft/blob/master/tests/fix_spectrum_mainchain.py having a fixture for a spectrum instance
• add your plugin into conftest.py
• Create a test with that fixture which uses rpc to execute that method

It might be that this only works locally and not in the CI but i think it's still valuable to do that.

I would say that the ability of downloading the whitepaper when it comes to code in this repo might be the best acceptance criteria for this PR to merge. So is it possible?
