-Please provide clear motivation for your patch and explain how it improves
-Bitcoin Core user experience or Bitcoin Core developer experience
-significantly:
-
-* Any test improvements or new tests that improve coverage are always welcome.
-* All other changes should have accompanying unit tests (see `src/test/`) or
-  functional tests (see `test/`). Contributors should note which tests cover
-  modified code. If no tests exist for a region of modified code, new tests
-  should accompany the change.
-* Bug fixes are most welcome when they come with steps to reproduce or an
-  explanation of the potential issue as well as reasoning for the way the bug
-  was fixed.
-* Features are welcome, but might be rejected due to design or scope issues.
-  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.

-Bitcoin Core has a thorough review process and even the most trivial change

 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.
 
-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 meritocracy where longer term contributors gain more trust from
-the developer community. However, 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, overall merging, moderation and appointment of maintainers.
-
-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.
-
-Communication Channels
-----------------------
-
-Most communication about Bitcoin Core development happens on IRC, in the
-#bitcoin-core-dev channel on Freenode. The easiest way to participate on IRC is
-with the web client, [webchat.freenode.net](https://webchat.freenode.net/). Chat
-history logs can be found
-on [http://www.erisian.com.au/bitcoin-core-dev/](http://www.erisian.com.au/bitcoin-core-dev/)
-and [http://gnusha.org/bitcoin-core-dev/](http://gnusha.org/bitcoin-core-dev/).
-
-Discussion about code base improvements happens in GitHub issues and on pull
-requests.
-
-The developer
-[mailing list](https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev)
-should be used to discuss complicated or controversial changes before working on
-a patch set.

-
-Note: 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 NAK'ing" the PR, the author may need to present arguments and/or do research backing their suggested changes.
-
-Squashing Commits
----------------------------
-If your pull request is accepted for merging, you may be asked by a maintainer
-to squash and or [rebase](https://git-scm.com/docs/git-rebase) your commits
-before it will be merged. 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 that you should not just list the
-interim commits.
-
-If you have problems with squashing (or other workflows with `git`), you can
-alternatively enable "Allow edits from maintainers" in the right GitHub
-sidebar and ask for help in the pull request.
-
-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.

 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
+###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.

-Project maintainers aim for a quick turnaround on refactoring pull requests, so

-
-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.

+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 and functional 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

-  - Change relevant comments and documentation when behaviour of code changes.
+  - 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 and functional tests where appropriate;
+  - follow code style guidelines;
+  - 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.

-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
+###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).
+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). The following language is used within pull-request comments:
 
-#### Conceptual Review
-
-A review can be a conceptual review, where the reviewer leaves a comment
- * `Concept (N)ACK`, meaning "I do (not) agree in 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. It is
-starting with `ACK BRANCH_COMMIT`, where `BRANCH_COMMIT` is the top of the
-topic branch. The review is 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 and functional
-    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";
+  - ACK means "I have tested the code and I agree it should be merged";
+  - NACK means "I disagree this should be merged", and must be accompanied by sound technical justification. NACKs without accompanying reasoning may be disregarded;
+  - utACK means "I have not tested the code, but I have reviewed it and it looks OK, I agree it can be merged";
+  - Concept ACK means "I agree in the general principle of this pull request";
   - Nit refers to trivial, often non-blocking issues.
 
-Project maintainers reserve the right to weigh the opinions of peer reviewers
-using common sense judgement and also may weight based on meritocracy: Those
-that have demonstrated a deeper commitment and understanding towards the project
-(over time) or have clear domain expertise may naturally have more weight, as
-one would expect in all walks of life.
+Reviewers should include the commit hash which they reviewed in their comments.
 
-Where a patch set affects consensus critical code, the bar will be set 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.

-### 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 the release is over. Wait for 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://help.github.com/articles/tracing-changes-in-a-file/). Simply
-    find the person touching the code you are touching before you 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 an unreasonably long amount of time (month+) for
-    no particular reason (few lines changed, etc), this is totally fine. Try to return the favor
-    when someone else is asking for feedback on their code, and universe balances out.
+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.

-# 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' (for the C++11 standard)
-#   or '14' (for the C++14 standard).
-#
-#   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 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.

-Building Bitcoin Core with Visual Studio
-========================================
-
-Introduction
----------------------
-Solution and project files to build the Bitcoin Core applications `msbuild` or Visual Studio can be found in the build_msvc directory. The build has been tested with Visual Studio 2017 and 2019.
-
-Building with Visual Studio is an alternative to the Linux based [cross-compiler build](https://github.com/bitcoin/bitcoin/blob/master/doc/build-windows.md).
-
-Quick Start
----------------------
-The minimal steps required to build Bitcoin Core with the msbuild toolchain are below. More detailed instructions are contained in the following sections.
-
-```
-vcpkg install --triplet x64-windows-static boost-filesystem boost-signals2 boost-test libevent openssl zeromq berkeleydb rapidcheck double-conversion
-py -3 build_msvc\msvc-autogen.py
-msbuild /m build_msvc\bitcoin.sln /p:Platform=x64 /p:Configuration=Release /t:build
-```
-
-Dependencies
----------------------
-A number of [open source libraries](https://github.com/bitcoin/bitcoin/blob/master/doc/dependencies.md) are required in order to be able to build Bitcoin Core.
-
-Options for installing the dependencies in a Visual Studio compatible manner are:
-
-- Use Microsoft's [vcpkg](https://docs.microsoft.com/en-us/cpp/vcpkg) to download the source packages and build locally. This is the recommended approach.
-- Download the source code, build each dependency, add the required include paths, link libraries and binary tools to the Visual Studio project files.
-- Use [nuget](https://www.nuget.org/) packages with the understanding that any binary files have been compiled by an untrusted third party.
-
-The [external dependencies](https://github.com/bitcoin/bitcoin/blob/master/doc/dependencies.md) required for building are:
-
-- Berkeley DB
-- Boost
-- DoubleConversion
-- libevent
-- OpenSSL
-- Qt5
-- RapidCheck
-- ZeroMQ
-
-Qt
----------------------
-All the Bitcoin Core applications are configured to build with static linking. In order to build the Bitcoin Core Qt applications a static build of Qt is required.
-
-The runtime library version (e.g. v141, v142) and platform type (x86 or x64) must also match. OpenSSL must also be linked into the Qt binaries in order to provide full functionality of the Bitcoin Core Qt programs. An example of the configure command to build Qtv5.9.7 locally to link with Bitcoin Core is shown below (adjust paths accordingly), note it can be expected that the configure and subsequent build will fail numerous times until dependency issues are resolved.

-````
-
-A prebuilt version for x64 and Visual C++ runtime v141 (Visual Studio 2017) can be downloaded from [here](https://github.com/sipsorcery/qt_win_binary/releases). Please be aware this download is NOT an officially sanctioned Bitcoin Core distribution and is provided for developer convenience. It should NOT be used for builds that will be used in a production environment or with real funds.
-
-To build Bitcoin Core without Qt unload or disable the bitcoin-qt, libbitcoin_qt and test_bitcoin-qt projects.
-
-Building
----------------------
-The instructions below use `vcpkg` to install the dependencies.
-
-- Install [`vcpkg`](https://github.com/Microsoft/vcpkg).
-- Install the required packages (replace x64 with x86 as required). The list of required packages can be found in the `build_msvc\vcpkg-packages.txt` file. The PowerShell command below will work if run from the repository root directory and `vcpkg` is in the path. Alternatively the contents of the packages text file can be pasted in place of the `Get-Content` cmdlet.
-
-```
-PS >.\vcpkg install --triplet x64-windows-static $(Get-Content -Path build_msvc\vcpkg-packages.txt).split()
-
-```
-
-- Use Python to generate *.vcxproj from Makefile
-
-```
-    PS >py -3 msvc-autogen.py
-```
-
-- 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.
-
-- Build with Visual Studio 2017 or msbuild.
-
-```
-msbuild /m bitcoin.sln /p:Platform=x64 /p:Configuration=Release /p:PlatformToolset=v141 /t:build
-```
-
-- Build with Visual Studio 2019 or msbuild.
-
-```
-msbuild /m bitcoin.sln /p:Platform=x64 /p:Configuration=Release /t:build
-```
-
-AppVeyor
----------------------
-The .appveyor.yml in the root directory is suitable to perform builds on [AppVeyor](https://www.appveyor.com/) Continuous Integration servers. The simplest way to perform an AppVeyor build is to fork Bitcoin Core and then configure a new AppVeyor Project pointing to the forked repository.
-
-For safety reasons the Bitcoin Core .appveyor.yml file has the artifact options disabled. The build will be performed but no executable files will be available. To enable artifacts on a forked repository uncomment the lines shown below:
-
-```
-    #- 7z a bitcoin-%APPVEYOR_BUILD_VERSION%.zip %APPVEYOR_BUILD_FOLDER%\build_msvc\%platform%\%configuration%\*.exe
-    #- path: bitcoin-%APPVEYOR_BUILD_VERSION%.zip
-```

-## ci scripts
-
-This directory contains scripts for each build step in each build stage.
-
-Currently three stages `lint`, `extended_lint` and `test` are defined. Each stage has its own lifecycle, similar to the
-[Travis CI lifecycle](https://docs.travis-ci.com/user/job-lifecycle#the-job-lifecycle). Every script in here is named
-and numbered according to which stage and lifecycle step it belongs to.
-
-### Running a stage locally
-
-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 ccache bash git
-```
-
-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
-```
-
-Be aware that the tests will be build 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.

-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                   Exponenetial Backoff: minimum sleep amount (seconds): Default 0.3
-        -x, --max=secs                   Exponenetial Backoff: maximum sleep amount (seconds): Default 60
-        -f, --fail="script +cmds"        Fail Script: run in case of final failure
-
-### Examples
-
-No problem:
-
-`retry echo u work good`
-
-    u work good
-
-Test functionality:
-
-`retry 'echo "y u no work"; false'`
-
-    y u no work
-    Before retry #1: sleeping 0.3 seconds
-    y u no work
-    Before retry #2: sleeping 0.6 seconds
-    y u no work
-    Before retry #3: sleeping 1.2 seconds
-    y u no work
-    Before retry #4: sleeping 2.4 seconds
-    y u no work
-    Before retry #5: sleeping 4.8 seconds
-    y u no work
-    Before retry #6: sleeping 9.6 seconds

-    y u no work
-    Before retry #9: sleeping 60.0 seconds
-    y u no work
-    Before retry #10: sleeping 60.0 seconds
-    y u no work
-    etc..
-
-Limit retries:
-
-`retry -t 4 'echo "y u no work"; false'`
-
-    y u no work
-    Before retry #1: sleeping 0.3 seconds
-    y u no work
-    Before retry #2: sleeping 0.6 seconds
-    y u no work
-    Before retry #3: sleeping 1.2 seconds
-    y u no work
-    Before retry #4: sleeping 2.4 seconds
-    y u no work
-    Retries exhausted
-
-Bad command:
-
-`retry poop`
-
-    bash: poop: command not found
-
-Fail command:
-
-`retry -t 3 -f 'echo "oh poopsickles"' 'echo "y u no work"; false'`
-
-    y u no work
-    Before retry #1: sleeping 0.3 seconds
-    y u no work
-    Before retry #2: sleeping 0.6 seconds
-    y u no work
-    Before retry #3: sleeping 1.2 seconds
-    y u no work
-    Retries exhausted, running fail script
-    oh poopsickles
-
-Last attempt passed:
-
-`retry -t 3 -- 'if [ $RETRY_ATTEMPT -eq 3 ]; then echo Passed at attempt $RETRY_ATTEMPT; true; else echo Failed at attempt $RETRY_ATTEMPT; false; fi;'`
-
-    Failed at attempt 0
-    Before retry #1: sleeping 0.3 seconds
-    Failed at attempt 1
-    Before retry #2: sleeping 0.6 seconds
-    Failed at attempt 2
-    Before retry #3: sleeping 1.2 seconds
-    Passed at attempt 3
