Pull request description:

  [An earlier approach](1d226ae1f9/) in #28956 involved simplifying and refactoring the network-adjusted time calculation logic, but this was eventually [left out](https://github.com/bitcoin/bitcoin/pull/28956#issuecomment-1904214370) of the PR to make it easier for reviewers to focus on consensus logic changes.

  Since network-adjusted time is now only used for warning/informational purposes, cleaning up the logic (building on @dergoegge's approach in #28956) should be quite straightforward and uncontroversial. The main changes are:

  - Previously, we would only calculate the time offset from the first 199 outbound peers that we connected to. This limitation is now removed, and we have a proper rolling calculation. I've reduced the set to 50 outbound peers, which seems plenty.
  - Previously, we would automatically use the network-adjusted time if the difference was < 70 mins, and warn the user if the difference was larger than that. Since there is no longer any automated time adjustment, I've changed the warning threshold to ~~20~~ 10 minutes (which is an arbitrary number).
  - Previously, a warning would only be raised once, and then never again until node restart. This behaviour is now updated to  1) warn to log for every new outbound peer for as long as we appear out of sync, 2) have the RPC warning toggled on/off whenever we go in/out of sync, and 3) have the GUI warn whenever we are out of sync (again), but limited to 1 messagebox per 60 minutes
  - no more globals
  - remove the `-maxtimeadjustment` startup arg

  Closes #4521

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.
