Pull request description:

  This PR fixes a dormant bug in MiniWallet that exists since support for P2TR was initially added in #23371 (see commit 041abfebe4).

  In the course of spending the output, the leaf version byte of the control block in the witness stack doesn't set the parity bit, i.e. we were so far just lucky that the used combinations of relevant data (internal pubkey, leaf script / version) didn't result in a tweaked pubkey with odd y-parity. If that was the case, we'd get the following validation error:

  `mandatory-script-verify-flag-failed (Witness program hash mismatch) (-26)`

  Since MiniWallets can now optionally be tagged (#29939), resulting in different internal pubkeys, the issue is more prevalent now. Fix it by passing the parity bit, as specified in BIP341.

  Can be tested with the following patch (fails on master, succeeds on PR):

       test_framework.generate(ephemeral_miniwallet, 1 + num_of_batches * tx_batch_size)

       # Mine enough blocks so that the UTXOs are allowed to be spent
  ```

  In addition to that, another bug is fixed where the internal key derivation failed, as not every pseudorandom hash results in a valid x-only pubkey. Fix this by treating the hash result as private key and calculate the x-only public key out of that, to be used then as internal key.

  Fixes #30528.

README.md

Bitcoin Core integration/staging tree

https://bitcoincore.org

For an immediately usable, binary version of the Bitcoin Core software, see https://bitcoincore.org/en/download/.

What is Bitcoin Core?

Bitcoin Core connects to the Bitcoin peer-to-peer network to download and fully validate blocks and transactions. It also includes a wallet and graphical user interface, which can be optionally built.

Further information about Bitcoin Core is available in the doc folder.

License

Bitcoin Core is released under the terms of the MIT license. See COPYING for more information or see https://opensource.org/licenses/MIT.

Development Process

The master branch is regularly built (see doc/build-*.md for instructions) and tested, but it is not guaranteed to be completely stable. Tags are created regularly from release branches to indicate new official, stable release versions of Bitcoin Core.

The https://github.com/bitcoin-core/gui repository is used exclusively for the development of the GUI. Its master branch is identical in all monotree repositories. Release branches and tags do not exist, so please do not fork that repository unless it is for development reasons.

The contribution workflow is described in CONTRIBUTING.md and useful hints for developers can be found in doc/developer-notes.md.

Testing

Testing and code review is the bottleneck for development; we get more pull requests than we can review and test on short notice. Please be patient and help out by testing other people's pull requests, and remember this is a security-critical project where any mistake might cost people lots of money.

Automated Testing

Developers are strongly encouraged to write unit tests for new code, and to submit new unit tests for old code. Unit tests can be compiled and run (assuming they weren't disabled in configure) with: make check. Further details on running and extending unit tests can be found in /src/test/README.md.

There are also regression and integration tests, written in Python. These tests can be run (if the test dependencies are installed) with: test/functional/test_runner.py

The CI (Continuous Integration) systems make sure that every pull request is built for Windows, Linux, and macOS, and that unit/sanity tests are run automatically.

Manual Quality Assurance (QA) Testing

Changes should be tested by somebody other than the developer who wrote the code. This is especially important for large or high-risk changes. It is useful to add a test plan to the pull request description if testing the changes is not straightforward.

Translations

Changes to translations as well as new translations can be submitted to Bitcoin Core's Transifex page.

Translations are periodically pulled from Transifex and merged into the git repository. See the translation process for details on how this works.

Important: We do not accept translation changes as GitHub pull requests because the next pull from Transifex would automatically overwrite them again.
