-  If a feature is based on a lot of dependencies, contributors should first
-  consider building the system outside of Bitcoin Core, if possible.
-* Refactoring changes are only accepted if they are required for a feature or
-  bug fix or otherwise improve developer experience significantly. For example,
-  most "code style" refactoring changes require a thorough explanation why they
-  are useful, what downsides they have and why they *significantly* improve
-  developer experience or avoid serious programming bugs. Note that code style
-  is often a subjective matter. Unless they are explicitly mentioned to be
-  preferred in the [developer notes](/doc/developer-notes.md), stylistic code
-  changes are usually rejected.

 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
+Firstly in terms of structure, there is no particular concept of "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, as well as a "lead maintainer" who is responsible for the
-[release cycle](/doc/release-process.md) as well as overall merging, moderation
-and appointment of maintainers.
-
-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.

+merging pull requests as well as a "lead maintainer" who is responsible for the
+release cycle, overall merging, moderation and appointment of maintainers.
 
 
 Contributor Workflow
 --------------------
 
 The codebase is maintained using the "contributor workflow" where everyone
-without exception contributes patch proposals using "pull requests" (PRs). This
+without exception contributes patch proposals using "pull requests". 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:
-

-  - `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 reproducible builds
+  - *Consensus* for changes to consensus critical code
+  - *Docs* for changes to the documentation

+  - *Mining* for changes to the mining code
+  - *Net* or *P2P* for changes to the peer-to-peer network code
+  - *RPC/REST/ZMQ* for changes to the RPC, REST or ZMQ APIs
+  - *Scripts and tools* for changes to the scripts and tools
+  - *Tests* for changes to the bitcoin unit tests or QA tests
+  - *Trivial* should **only** be used for PRs that do not change generated
+    executable code. Notably, refactors (change of function arguments and code
+    reorganization) and changes in behavior should **not** be marked as trivial.
+    Examples of trivial PRs are changes to:
+    - comments
+    - whitespace
+    - variable names
+    - logging and messages
+  - *Utils and libraries* for changes to the utils and libraries
+  - *Wallet* for changes to the wallet code
 
 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

     git checkout your_branch_name

-    # 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.

-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.

-### 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.
-The `git rebase` command will take care of rebuilding your 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

-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](

+# SYNOPSIS
+#
+#   AX_GCC_FUNC_ATTRIBUTE(ATTRIBUTE)
+#
+# DESCRIPTION
+#
+#   This macro checks if the compiler supports one of GCC's function
+#   attributes; many other compilers also provide function attributes with
+#   the same syntax. Compiler warnings are used to detect supported
+#   attributes as unsupported ones are ignored by default so quieting
+#   warnings when using this macro will yield false positives.
+#
+#   The ATTRIBUTE parameter holds the name of the attribute to be checked.
+#
+#   If ATTRIBUTE is supported define HAVE_FUNC_ATTRIBUTE_<ATTRIBUTE>.
+#
+#   The macro caches its result in the ax_cv_have_func_attribute_<attribute>
+#   variable.
+#
+#   The macro currently supports the following function attributes:
+#
+#    alias
+#    aligned
+#    alloc_size
+#    always_inline
+#    artificial
+#    cold
+#    const
+#    constructor
+#    constructor_priority for constructor attribute with priority
+#    deprecated
+#    destructor
+#    dllexport
+#    dllimport
+#    error
+#    externally_visible
+#    flatten
+#    format
+#    format_arg
+#    gnu_inline
+#    hot
+#    ifunc
+#    leaf
+#    malloc
+#    noclone
+#    noinline
+#    nonnull
+#    noreturn
+#    nothrow
+#    optimize
+#    pure
+#    unused
+#    used
+#    visibility
+#    warning
+#    warn_unused_result
+#    weak
+#    weakref
+#
+#   Unsuppored function attributes will be tested with a prototype returning
+#   an int and not accepting any arguments and the result of the check might
+#   be wrong or meaningless so use with care.

-Building Bitcoin Core with Visual Studio
-========================================
-
-Introduction
----------------------
-Solution and project files to build Bitcoin Core with `msbuild` or Visual Studio can be found in the `build_msvc` directory. The build has been tested with Visual Studio 2019 (building with earlier versions of Visual Studio should not be expected to work).
-
-To build Bitcoin Core from the command-line, it is sufficient to only install the Visual Studio Build Tools component.
-
-Building with Visual Studio is an alternative to the Linux based [cross-compiler build](../doc/build-windows.md).
-
-
-Prerequisites
----------------------
-To build [dependencies](../doc/dependencies.md) (except for [Qt](#qt)),
-the default approach is to use the [vcpkg](https://docs.microsoft.com/en-us/cpp/vcpkg) package manager from Microsoft:
-
-1. [Install](https://vcpkg.io/en/getting-started.html) vcpkg.
-
-2. By default, vcpkg makes both `release` and `debug` builds for each package.
-To save build time and disk space, one could skip `debug` builds (example uses PowerShell):
-```powershell
-
-Add-Content -Path "vcpkg\triplets\x64-windows-static.cmake" -Value "set(VCPKG_BUILD_TYPE release)"
-```
-
-Qt
----------------------
-To build Bitcoin Core with the GUI, a static build of Qt is required.
-
-1. Download a single ZIP archive of Qt source code from https://download.qt.io/official_releases/qt/ (e.g., [`qt-everywhere-src-5.15.2.zip`](https://download.qt.io/official_releases/qt/5.15/5.15.2/single/qt-everywhere-src-5.15.2.zip)), and expand it into a dedicated folder. The following instructions assume that this folder is `C:\dev\qt-source`.
-
-2. Open "x64 Native Tools Command Prompt for VS 2019", and input the following commands:
-```cmd
-cd C:\dev\qt-source
-mkdir build
-cd build
-..\configure -release -silent -opensource -confirm-license -opengl desktop -static -static-runtime -mp -qt-zlib -qt-pcre -qt-libpng -nomake examples -nomake tests -nomake tools -no-angle -no-dbus -no-gif -no-gtk -no-ico -no-icu -no-libjpeg -no-libudev -no-sql-sqlite -no-sql-odbc -no-sqlite -no-vulkan -skip qt3d -skip qtactiveqt -skip qtandroidextras -skip qtcharts -skip qtconnectivity -skip qtdatavis3d -skip qtdeclarative -skip doc -skip qtdoc -skip qtgamepad -skip qtgraphicaleffects -skip qtimageformats -skip qtlocation -skip qtlottie -skip qtmacextras -skip qtmultimedia -skip qtnetworkauth -skip qtpurchasing -skip qtquick3d -skip qtquickcontrols -skip qtquickcontrols2 -skip qtquicktimeline -skip qtremoteobjects -skip qtscript -skip qtscxml -skip qtsensors -skip qtserialbus -skip qtserialport -skip qtspeech -skip qtsvg -skip qtvirtualkeyboard -skip qtwayland -skip qtwebchannel -skip qtwebengine -skip qtwebglplugin -skip qtwebsockets -skip qtwebview -skip qtx11extras -skip qtxmlpatterns -no-openssl -no-feature-bearermanagement -no-feature-printdialog -no-feature-printer -no-feature-printpreviewdialog -no-feature-printpreviewwidget -no-feature-sql -no-feature-sqlmodel -no-feature-textbrowser -no-feature-textmarkdownwriter -no-feature-textodfwriter -no-feature-xml -prefix C:\Qt_static
-nmake
-nmake install
-```
-
-One could speed up building with [`jom`](https://wiki.qt.io/Jom), a replacement for `nmake` which makes use of all CPU cores.
-
-To build Bitcoin Core without Qt, unload or disable the `bitcoin-qt`, `libbitcoin_qt` and `test_bitcoin-qt` projects.
-
-
-Building
----------------------
-1. Use Python to generate `*.vcxproj` from Makefile:
-
-```
-PS >py -3 msvc-autogen.py
-```
-
-2. An optional step is to adjust the settings in the `build_msvc` directory and the `common.init.vcxproj` file. This project file contains settings that are common to all projects such as the runtime library version and target Windows SDK version. The Qt directories can also be set. To specify a non-default path to a static Qt package directory, use the `QTBASEDIR` environment variable.
-
-3. To build from the command-line with the Visual Studio 2019 toolchain use:
-
-```cmd
-msbuild -property:Configuration=Release -maxCpuCount -verbosity:minimal bitcoin.sln
-```
-
-Alternatively, open the `build_msvc/bitcoin.sln` file in Visual Studio 2019.
-
-Security
----------------------
-[Base address randomization](https://docs.microsoft.com/en-us/cpp/build/reference/dynamicbase-use-address-space-layout-randomization?view=msvc-160) is used to make Bitcoin Core more secure. When building Bitcoin using the `build_msvc` process base address randomization can be disabled by editing `common.init.vcproj` to change `RandomizedBaseAddress` from `true` to `false` and then rebuilding the project.
-
-To check if `bitcoind` has `RandomizedBaseAddress` enabled or disabled run
-
-```
-.\dumpbin.exe /headers src/bitcoind.exe
-```
-
-If is it enabled then in the output `Dynamic base` will be listed in the `DLL characteristics` under `OPTIONAL HEADER VALUES` as shown below
-
-```
-            8160 DLL characteristics
-                   High Entropy Virtual Addresses
-                   Dynamic base
-                   NX compatible
-                   Terminal Server Aware
-```
-
-This may not disable all stack randomization as versions of windows employ additional stack randomization protections. These protections must be turned off in the OS configuration.

-## CI Scripts
-
-This directory contains scripts for each build step in each build stage.
-
-### Running a Stage Locally
-
-Be aware that the tests will be built and run in-place, so please run at your own risk.
-If the repository is not a fresh git clone, you might have to clean files from previous builds or test runs first.
-
-The ci needs to perform various sysadmin tasks such as installing packages or writing to the user's home directory.
-While most of the actions are done inside a docker container, this is not possible for all. Thus, cache directories,
-such as the depends cache, previous release binaries, or ccache, are mounted as read-write into the docker container. While it should be fine to run
-the ci system locally on you development box, the ci scripts can generally be assumed to have received less review and
-testing compared to other parts of the codebase. If you want to keep the work tree clean, you might want to run the ci
-system in a virtual machine with a Linux operating system of your choice.
-
-To allow for a wide range of tested environments, but also ensure reproducibility to some extent, the test stage
-requires `docker` to be installed. To install all requirements on Ubuntu, run
-
-```
-sudo apt install docker.io bash
-```
-
-To run the default test stage,
-
-```
-./ci/test_run_all.sh
-```
-
-To run the test stage with a specific configuration,
-
-```
-FILE_ENV="./ci/test/00_setup_env_arm.sh" ./ci/test_run_all.sh
-```
-
-### Configurations
-
-The test files (`FILE_ENV`) are constructed to test a wide range of
-configurations, rather than a single pass/fail. This helps to catch build
-failures and logic errors that present on platforms other than the ones the
-author has tested.
-
-Some builders use the dependency-generator in `./depends`, rather than using
-the system package manager to install build dependencies. This guarantees that
-the tester is using the same versions as the release builds, which also use
-`./depends`.
-
-If no `FILE_ENV` has been specified or values are left out, `00_setup_env.sh`
-is used as the default configuration with fallback values.
-
-It is also possible to force a specific configuration without modifying the
-file. For example,
-
-```
-MAKEJOBS="-j1" FILE_ENV="./ci/test/00_setup_env_arm.sh" ./ci/test_run_all.sh
-```
-
-The files starting with `0n` (`n` greater than 0) are the scripts that are run
-in order.
-
-### Cache
-
-In order to avoid rebuilding all dependencies for each build, the binaries are
-cached and re-used when possible. Changes in the dependency-generator will
-trigger cache-invalidation and rebuilds as necessary.

-retry - The command line retry tool
-------------------------------------------
-
-Retry any shell command with exponential backoff or constant delay.
-
-### Instructions
-
-Install:
-
-retry is a shell script, so drop it somewhere and make sure it's added to your $PATH. Or you can use the following one-liner:
-
-```sh
-sudo sh -c "curl https://raw.githubusercontent.com/kadwanev/retry/master/retry -o /usr/local/bin/retry && chmod +x /usr/local/bin/retry"
-```
-
-If you're on OS X, retry is also on Homebrew:
-
-```
-brew pull 27283
-brew install retry
-```
-Not popular enough for homebrew-core. Please star this project to help.
-
-### Usage
-
-Help:
-
-`retry -?`
-
-    Usage: retry [options] -- execute command
-        -h, -?, --help
-        -v, --verbose                    Verbose output
-        -t, --tries=#                    Set max retries: Default 10
-        -s, --sleep=secs                 Constant sleep amount (seconds)
-        -m, --min=secs                   Exponential Backoff: minimum sleep amount (seconds): Default 0.3
-        -x, --max=secs                   Exponential Backoff: maximum sleep amount (seconds): Default 60
-        -f, --fail="script +cmds"        Fail Script: run in case of final failure
-
