bitcoin/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](/doc).
License
-------
Bitcoin Core is released under the terms of the MIT license. See [COPYING](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](https://github.com/bitcoin/bitcoin/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](CONTRIBUTING.md)
and useful hints for developers can be found in [doc/developer-notes.md](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](src/test/README.md) 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](/src/test/README.md).
There are also [regression and integration tests](/test), written
in Python.
These tests can be run (if the [test dependencies](/test) 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](https://www.transifex.com/bitcoin/bitcoin/).
Translations are periodically pulled from Transifex and merged into the git repository. See the
[translation process](doc/translation_process.md) 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.

bitcoin/CONTRIBUTING.md | Contributing to Bitcoin Core
============================
The Bitcoin Core project operates an open contributor model where anyone is
welcome to contribute towards development in the form of peer review, testing
and patches. This document explains the practical process and guidelines for
contributing.
First, in terms of structure, there is no particular concept of "Bitcoin Core
developers" in the sense of privileged people. Open source often naturally
revolves around a meritocracy where contributors earn trust from the developer
community over time. Nevertheless, some hierarchy is necessary for practical
purposes. As such, there are repository maintainers who are responsible for
merging pull requests, the [release cycle](/doc/release-process.md), and
moderation.
Getting Started
---------------
New contributors are very welcome and needed.
Reviewing and testing is highly valued and the most effective way you can contribute
as a new contributor. It also will teach you much more about the code and
process than opening pull requests. Please refer to the [peer review](#peer-review)
section below.
Before you start contributing, familiarize yourself with the Bitcoin Core build
system and tests. Refer to the documentation in the repository on how to build
Bitcoin Core and how to run the unit tests, functional tests, and fuzz tests.
There are many open issues of varying difficulty waiting to be fixed.
If you're looking for somewhere to start contributing, check out the
[good first issue](https://github.com/bitcoin/bitcoin/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22)
list or changes that are
[up for grabs](https://github.com/bitcoin/bitcoin/issues?utf8=%E2%9C%93&q=label%3A%22Up+for+grabs%22).
Some of them might no longer be applicable. So if you are interested, but
unsure, you might want to leave a comment on the issue first.
You may also participate in the weekly
[Bitcoin Core PR Review Club](https://bitcoincore.reviews/) meeting.
### Good First Issue Label
The purpose of the `good first issue` label is to highlight which issues are
suitable for a new contributor without a deep understanding of the codebase.
However, good first issues can be solved by anyone. If they remain unsolved
for a longer time, a frequent contributor might address them.
You do not need to request permission to start working on an issue. However,
you are encouraged to leave a comment if you are planning to work on it. This
will help other contributors monitor which issues are actively being addressed
and is also an effective way to request assistance if and when you need it.
Communication Channels
----------------------
Most communication about Bitcoin Core development happens on IRC, in the
`#bitcoin-core-dev` channel on Libera Chat. The easiest way to participate on IRC is
with the web client, [web.libera.chat](https://web.libera.chat/#bitcoin-core-dev). Chat
history logs can be found
on [https://www.erisian.com.au/bitcoin-core-dev/](https://www.erisian.com.au/bitcoin-core-dev/)
and [https://gnusha.org/bitcoin-core-dev/](https://gnusha.org/bitcoin-core-dev/).
Discussion about codebase improvements happens in GitHub issues and pull
requests.
The developer
[mailing list](https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev)
should be used to discuss complicated or controversial consensus or P2P protocol changes before working on
a patch set.
Contributor Workflow
--------------------
The codebase is maintained using the "contributor workflow" where everyone
without exception contributes patch proposals using "pull requests" (PRs). This
facilitates social contribution, easy testing and peer review.
To contribute a patch, the workflow is as follows:
1. Fork repository ([only for the first time](https://docs.github.com/en/get-started/quickstart/fork-a-repo))
1. Create topic branch
1. Commit patches
For GUI-related issues or pull requests, the https://github.com/bitcoin-core/gui repository should be used.
For all other issues and pull requests, the https://github.com/bitcoin/bitcoin node repository should be used.
The master branch for all monotree repositories is identical.
As a rule of thumb, everything that only modifies `src/qt` is a GUI-only pull
request. However:
* For global refactoring or other transversal changes the node repository
should be used.
* For GUI-related build system changes, the node repository should be used
because the change needs review by the build systems reviewers.
* Changes in `src/interfaces` need to go to the node repository because they
might affect other components like the wallet.
For large GUI changes that include build system and interface changes, it is
recommended to first open a pull request against the GUI repository. When there
is agreement to proceed with the changes, a pull request with the build system
and interfaces changes can be submitted to the node repository.
The project coding conventions in the [developer notes](doc/developer-notes.md)
must be followed.
### Committing Patches
In general, [commits should be atomic](https://en.wikipedia.org/wiki/Atomic_commit#Atomic_commit_convention)
and diffs should be easy to read. For this reason, do not mix any formatting
fixes or code moves with actual code changes.
Make sure each individual commit is hygienic: that it builds successfully on its
own without warnings, errors, regressions, or test failures.
Commit messages should be verbose by default consisting of a short subject line
(50 chars max), a blank line and detailed explanatory text as separate
paragraph(s), unless the title alone is self-explanatory (like "Correct typo
in init.cpp") in which case a single title line is sufficient. Commit messages should be
helpful to people reading your code in the future, so explain the reasoning for
your decisions. Further explanation [here](https://chris.beams.io/posts/git-commit/).
If a particular commit references another issue, please add the reference. For
example: `refs #1234` or `fixes #4321`. Using the `fixes` or `closes` keywords
will cause the corresponding issue to be closed when the pull request is merged.
Commit messages should never contain any `@` mentions (usernames prefixed with "@").
Please refer to the [Git manual](https://git-scm.com/doc) for more information
about Git.
- Push changes to your fork
- Create pull request
### Creating the Pull Request
The title of the pull request should be prefixed by the component or area that
the pull request affects. Valid areas as:
- `consensus` for changes to consensus critical code
- `doc` for changes to the documentation
- `qt` or `gui` for changes to bitcoin-qt
- `log` for changes to log messages
- `mining` for changes to the mining code
- `net` or `p2p` for changes to the peer-to-peer network code
- `refactor` for structural changes that do not change behavior
- `rpc`, `rest` or `zmq` for changes to the RPC, REST or ZMQ APIs
- `script` for changes to the scripts and tools
- `test`, `qa` or `ci` for changes to the unit tests, QA tests or CI code
- `util` or `lib` for changes to the utils or libraries
- `wallet` for changes to the wallet code
- `build` for changes to the GNU Autotools or MSVC builds
- `guix` for changes to the GUIX reproducible builds
Examples:
consensus: Add new opcode for BIP-XXXX OP_CHECKAWESOMESIG
net: Automatically create onion service, listen on Tor
qt: Add feed bump button
log: Fix typo in log message
The body of the pull request should contain sufficient description of *what* the
patch does, and even more importantly, *why*, with justification and reasoning.
You should include references to any discussions (for example, other issues or
mailing list discussions).
The description for a new pull request should not contain any `@` mentions. The
PR description will be included in the commit message when the PR is merged and
any users mentioned in the description will be annoyingly notified each time a
fork of Bitcoin Core copies the merge. Instead, make any username mentions in a
subsequent comment to the PR.
### Translation changes
Note that translations should not be submitted as pull requests. Please see
[Translation Process](https://github.com/bitcoin/bitcoin/blob/master/doc/translation_process.md)
for more information on helping with translations.
### Work in Progress Changes and Requests for Comments
If a pull request is not to be considered for merging (yet), please
prefix the title with [WIP] or use [Tasks Lists](https://docs.github.com/en/github/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax#task-lists)
in the body of the pull request to indicate tasks are pending.
### Address Feedback
At this stage, one should expect comments and review from other contributors. You
can add more commits to your pull request by committing them locally and pushing
to your fork.
You are expected to reply to any review comments before your pull request is
merged. You may update the code or reject the feedback if you do not agree with
it, but you should express so in a reply. If there is outstanding feedback and
you are not actively working on it, your pull request may be closed.
Please refer to the [peer review](#peer-review) section below for more details.
### Squashing Commits
If your pull request contains fixup commits (commits that change the same line of code repeatedly) or too fine-grained
commits, you may be asked to [squash](https://git-scm.com/docs/git-rebase#_interactive_mode) your commits
before it will be reviewed. The basic squashing workflow is shown below.
git checkout your_branch_name
git rebase -i HEAD~n
# n is normally the number of commits in the pull request.
# Set commits (except the one in the first line) from 'pick' to 'squash', save and quit.
# On the next screen, edit/refine commit messages.
# Save and quit.
git push -f # (force push to GitHub)
Please update the resulting commit message, if needed. It should read as a
coherent message. In most cases, this means not just listing the interim
commits.
If your change contains a merge commit, the above workflow may not work and you
will need to remove the merge commit first. See the next section for details on
how to rebase.
Please refrain from creating several pull requests for the same change.
Use the pull request that is already open (or was created earlier) to amend
changes. This preserves the discussion and review that happened earlier for
the respective change set.
The length of time required for peer review is unpredictable and will vary from
pull request to pull request.
### Rebasing Changes
When a pull request conflicts with the target branch, you may be asked to rebase it on top of the current target branch.
git fetch https://github.com/bitcoin/bitcoin # Fetch the latest upstream commit
git rebase FETCH_HEAD # Rebuild commits on top of the new base
This project aims to have a clean git history, where code changes are only made in non-merge commits. This simplifies
auditability because merge commits can be assumed to not contain arbitrary code changes. Merge commits should be signed,
and the resulting git tree hash must be deterministic and reproducible. The script in
[/contrib/verify-commits](/contrib/verify-commits) checks that.
After a rebase, reviewers are encouraged to sign off on the force push. This should be relatively straightforward with
the `git range-diff` tool explained in the [productivity
notes](/doc/productivity.md#diff-the-diffs-with-git-range-diff). To avoid needless review churn, maintainers will
generally merge pull requests that received the most review attention first.
Pull Request Philosophy
-----------------------
Patchsets should always be focused. For example, a pull request could add a
feature, fix a bug, or refactor code; but not a mixture. Please also avoid super
pull requests which attempt to do too much, are overly large, or overly complex
as this makes review difficult.
### Features
When adding a new feature, thought must be given to the long term technical debt
and maintenance that feature may require after inclusion. Before proposing a new
feature that will require maintenance, please consider if you are willing to
maintain it (including bug fixing). If features get orphaned with no maintainer
in the future, they may be removed by the Repository Maintainer.
### Refactoring
Refactoring is a necessary part of any software project's evolution. The
following guidelines cover refactoring pull requests for the project.
There are three categories of refactoring: code-only moves, code style fixes, and
code refactoring. In general, refactoring pull requests should not mix these
three kinds of activities in order to make refactoring pull requests easy to
review and uncontroversial. In all cases, refactoring PRs must not change the
behaviour of code within the pull request (bugs must be preserved as is).
Project maintainers aim for a quick turnaround on refactoring pull requests, so
where possible keep them short, uncomplex and easy to verify.
Pull requests that refactor the code should not be made by new contributors. It
requires a certain level of experience to know where the code belongs to and to
understand the full ramification (including rebase effort of open pull requests).
Trivial pull requests or pull requests that refactor the code with no clear
benefits may be immediately closed by the maintainers to reduce unnecessary
workload on reviewing.
"Decision Making" Process
-------------------------
The following applies to code changes to the Bitcoin Core project (and related
projects such as libsecp256k1), and is not to be confused with overall Bitcoin
Network Protocol consensus changes.
Whether a pull request is merged into Bitcoin Core rests with the project merge
maintainers.
Maintainers will take into consideration if a patch is in line with the general
principles of the project; meets the minimum standards for inclusion; and will
judge the general consensus of contributors.
In general, all pull requests must:
- Have a clear use case, fix a demonstrable bug or serve the greater good of
the project (for example refactoring for modularisation);
- Be well peer-reviewed;
- Have unit tests, functional tests, and fuzz tests, where appropriate;
- Follow code style guidelines ([C++](doc/developer-notes.md), [functional tests](test/functional/README.md));
- Not break the existing test suite;
- Where bugs are fixed, where possible, there should be unit tests
demonstrating the bug and also proving the fix. This helps prevent regression.
- Change relevant comments and documentation when behaviour of code changes.
Patches that change Bitcoin consensus rules are considerably more involved than
normal because they affect the entire ecosystem and so must be preceded by
extensive mailing list discussions and have a numbered BIP. While each case will
be different, one should be prepared to expend more time and effort than for
other kinds of patches because of increased peer review and consensus building
requirements.
### Peer Review
Anyone may participate in peer review which is expressed by comments in the pull
request. Typically reviewers will review the code for obvious errors, as well as
test out the patch set and opine on the technical merits of the patch. Project
maintainers take into account the peer review when determining if there is
consensus to merge a pull request (remember that discussions may have been
spread out over GitHub, mailing list and IRC discussions).
Code review is a burdensome but important part of the development process, and
as such, certain types of pull requests are rejected. In general, if the
**improvements** do not warrant the **review effort** required, the PR has a
high chance of being rejected. It is up to the PR author to convince the
reviewers that the changes warrant the review effort, and if reviewers are
"Concept NACK'ing" the PR, the author may need to present arguments and/or do
research backing their suggested changes.
#### Conceptual Review
A review can be a conceptual review, where the reviewer leaves a comment
* `Concept (N)ACK`, meaning "I do (not) agree with the general goal of this pull
request",
* `Approach (N)ACK`, meaning `Concept ACK`, but "I do (not) agree with the
approach of this change".
A `NACK` needs to include a rationale why the change is not worthwhile.
NACKs without accompanying reasoning may be disregarded.
#### Code Review
After conceptual agreement on the change, code review can be provided. A review
begins with `ACK BRANCH_COMMIT`, where `BRANCH_COMMIT` is the top of the PR
branch, followed by a description of how the reviewer did the review. The
following language is used within pull request comments:
- "I have tested the code", involving change-specific manual testing in
addition to running the unit, functional, or fuzz tests, and in case it is
not obvious how the manual testing was done, it should be described;
- "I have not tested the code, but I have reviewed it and it looks
OK, I agree it can be merged";
- A "nit" refers to a trivial, often non-blocking issue.
Project maintainers reserve the right to weigh the opinions of peer reviewers
using common sense judgement and may also weigh based on merit. Reviewers that
have demonstrated a deeper commitment and understanding of the project over time
or who have clear domain expertise may naturally have more weight, as one would
expect in all walks of life.
Where a patch set affects consensus-critical code, the bar will be much
higher in terms of discussion and peer review requirements, keeping in mind that
mistakes could be very costly to the wider community. This includes refactoring
of consensus-critical code.
Where a patch set proposes to change the Bitcoin consensus, it must have been
discussed extensively on the mailing list and IRC, be accompanied by a widely
discussed BIP and have a generally widely perceived technical consensus of being
a worthwhile change based on the judgement of the maintainers.
### Finding Reviewers
As most reviewers are themselves developers with their own projects, the review
process can be quite lengthy, and some amount of patience is required. If you find
that you've been waiting for a pull request to be given attention for several
months, there may be a number of reasons for this, some of which you can do something
about:
- It may be because of a feature freeze due to an upcoming release. During this time,
only bug fixes are taken into consideration. If your pull request is a new feature,
it will not be prioritized until after the release. Wait for the release.
- It may be because the changes you are suggesting do not appeal to people. Rather than
nits and critique, which require effort and means they care enough to spend time on your
contribution, thundering silence is a good sign of widespread (mild) dislike of a given change
(because people don't assume *others* won't actually like the proposal). Don't take
that personally, though! Instead, take another critical look at what you are suggesting
and see if it: changes too much, is too broad, doesn't adhere to the
[developer notes](doc/developer-notes.md), is dangerous or insecure, is messily written, etc.
Identify and address any of the issues you find. Then ask e.g. on IRC if someone could give
their opinion on the concept itself.
- It may be because your code is too complex for all but a few people, and those people
may not have realized your pull request even exists. A great way to find people who
are qualified and care about the code you are touching is the
[Git Blame feature](https://docs.github.com/en/github/managing-files-in-a-repository/managing-files-on-github/tracking-changes-in-a-file). Simply
look up who last modified the code you are changing and see if you can find
them and give them a nudge. Don't be incessant about the nudging, though.
- Finally, if all else fails, ask on IRC or elsewhere for someone to give your pull request
a look. If you think you've been waiting for an unreasonably long time (say,
more than a month) for no particular reason (a few lines changed, etc.),
this is totally fine. Try to return the favor when someone else is asking
for feedback on their code, and the universe balances out.
- Remember that the best thing you can do while waiting is give review to others!
Backporting
-----------
Security and bug fixes can be backported from `master` to release
branches.
If the backport is non-trivial, it may be appropriate to open an
additional PR to backport the change, but only after the original PR
has been merged.
Otherwise, backports will be done in batches and
the maintainers will use the proper `Needs backport (...)` labels
when needed (the original author does not need to worry about it).
A backport should contain the following metadata in the commit body:
```
Github-Pull: #<PR number>
Rebased-From: <commit hash of the original commit>
```
Have a look at [an example backport PR](
https://github.com/bitcoin/bitcoin/pull/16189).
Also see the [backport.py script](
https://github.com/bitcoin-core/bitcoin-maintainer-tools#backport).

# https://cirrus-ci.org/guide/persistent-workers/
#
# It is possible to select a specific persistent worker by label. Refer to the
# Cirrus CI docs for more details.
#
# Generally, a persistent worker must run Ubuntu 23.04+ or Debian 12+.
# Specifically,
# - apt-get is required due to PACKAGE_MANAGER_INSTALL
# - podman-docker-4.1+ is required due to the use of `podman` when
# RESTART_CI_DOCKER_BEFORE_RUN is set and 4.1+ due to the bugfix in 4.1
# (https://github.com/bitcoin/bitcoin/pull/21652#issuecomment-1657098200)
# - The ./ci/ depedencies (with cirrus-cli) should be installed:
#
# ```
# apt update && apt install screen python3 bash podman-docker curl -y && curl -L -o cirrus "https://github.com/cirruslabs/cirrus-cli/releases/latest/download/cirrus-linux-$(dpkg --print-architecture)" && mv cirrus /usr/local/bin/cirrus && chmod +x /usr/local/bin/cirrus
# ```
#
# - There are no strict requirements on the hardware, because having less CPUs
# runs the same CI script (maybe slower). To avoid rare and intermittent OOM
# due to short memory usage spikes, it is recommended to add (and persist)
# swap:
#
# ```
# fallocate -l 16G /swapfile_ci && chmod 600 /swapfile_ci && mkswap /swapfile_ci && swapon /swapfile_ci && ( echo '/swapfile_ci none swap sw 0 0' | tee -a /etc/fstab )
# ```
#
# - To register the persistent worker, open a `screen` session and run:
#
# ```
# RESTART_CI_DOCKER_BEFORE_RUN=1 screen cirrus worker run --labels type=todo_fill_in_type --token todo_fill_in_token
# ```
#
# The following specific types should exist, with the following requirements:
# - small: For an x86_64 machine, recommended to have 2 CPUs and 8 GB of memory.
# - medium: For an x86_64 machine, recommended to have 4 CPUs and 16 GB of memory.
# - noble: For a machine running the Linux kernel shipped with exaclty Ubuntu Noble 24.04. The machine is recommended to have 4 CPUs and 16 GB of memory.
# - arm64: For an aarch64 machine, recommended to have 2 CPUs and 8 GB of memory.

# AX_CHECK_PREPROC_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])
#
# DESCRIPTION
#
# Check whether the given FLAG works with the current language's
# preprocessor or gives an error. (Warnings, however, are ignored)
#
# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
# success/failure.
#
# If EXTRA-FLAGS is defined, it is added to the preprocessor's default
# flags when the check is done. The check is thus made with the flags:
# "CPPFLAGS EXTRA-FLAGS FLAG". This can for example be used to force the
# preprocessor to issue an error when a bad flag is given.
#
# INPUT gives an alternative input source to AC_PREPROC_IFELSE.

# macro in sync with AX_CHECK_{COMPILE,LINK}_FLAG.

# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
# success/failure.
#
# If EXTRA-FLAGS is defined, it is added to the current language's default
# flags (e.g. CFLAGS) when the check is done. The check is thus made with
# the flags: "CFLAGS EXTRA-FLAGS FLAG". This can for example be used to
# force the compiler to issue an error when a bad flag is given.
#
# INPUT gives an alternative input source to AC_COMPILE_IFELSE.
#
# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
# macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.

#
# SYNOPSIS
#
# AX_CXX_COMPILE_STDCXX(VERSION, [ext|noext], [mandatory|optional])
#
# DESCRIPTION
#
# Check for baseline language coverage in the compiler for the specified
# version of the C++ standard. If necessary, add switches to CXX and
# CXXCPP to enable support. VERSION may be '11', '14', '17', or '20' for
# the respective C++ standard version.
#
# The second argument, if specified, indicates whether you insist on an
# extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
# -std=c++11). If neither is specified, you get whatever works, with
# preference for no added switch, and then for an extended mode.
#
# The third argument, if specified 'mandatory' or if left unspecified,
# indicates that baseline support for the specified C++ standard is
# required and that the macro should error out if no mode with that
# support is found. If specified 'optional', then configuration proceeds
# regardless, after defining HAVE_CXX${VERSION} if and only if a
# supporting mode is found.
