041abfebe49ae5e3e882c00cc5caea1365a27a49 test: MiniWallet: add P2TR support and use it per default (Sebastian Falbesoner) 4a2edf2bf708b6044562995e35f2dbbd2b26c364 test: generate blocks to MiniWallet address in rpc_blockchain.py (Sebastian Falbesoner) Pull request description: Taproot activates in [about 19 days](https://taproot.watch/) (2716 blocks), and it'd be nice if we set a good example and also support it in our MiniWallet. This PR changes the default mode from P2WSH (segwit v0 output, bech32 address) to P2TR (segwit v1 output, bech32m address) transactions type with the _anyone-can-spend_ policy, i.e. a witness script of `OP_TRUE`. The transition is actually quite painless, one only needs one extra piece in the form of a internal public key that is passed in the control block on the witness stack, in order to trigger script-path spending. To keep things simple, the lowest possible valid x-only-public key with the value of 1 was chosen as internal key. Since many tests expect to find outputs for the default scriptPubKey of MiniWallet in the pre-mined chain of the test framework, the generation address is also changed from `ADDRESS_BCRT1_P2WSH_OP_TRUE` to `create_deterministic_address_bcrt1_p2tr_op_true()[0]` accordingly (see method `BitcoinTestFramework._initialize_chain(...)`). Note that the pre-mined chain is cached locally, so you probably have to delete the `./test/cache` folder first for the tests to pass again. In order to avoid unnecessary renames, the import of `ADDRESS_BCRT1_P2WSH_OP_TRUE` is eliminated in rpc_blockchain.py by generating blocks directly to the MiniWallet address by using the `self.generate(self.wallet, ...)` interface (see first commit).

What is Bitcoin?
Bitcoin is an experimental digital currency that enables instant payments to anyone, anywhere in the world. Bitcoin uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. Bitcoin Core is the name of open source software which enables the use of this currency.

License

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.
