+# Contributing to Vexta Core
+
+Thank you for your interest in contributing to Vexta Core.
+
+Vexta Core is a Bitcoin Core–based blockchain focused on long-term stability, maintainability, and compatibility. Contributions that improve code quality, reliability, documentation, testing, or performance are welcome.
+
+---
+
+## Development Philosophy
+
+The project follows a simple set of principles:
+
+- Keep consensus changes to an absolute minimum.
+- Stay as close to upstream Bitcoin Core as practical.
+- Prefer simple, readable, and maintainable code.
+- Remove legacy code instead of extending it.
+- Preserve compatibility with standard Bitcoin ecosystem software whenever possible.
+
+---
+
+## Contributor Workflow
+
+1. Fork the repository.
+2. Create a feature branch.
+3. Make focused, self-contained changes.
+4. Ensure the project builds successfully.
+5. Run the available tests.
+6. Submit a pull request with a clear description.
+
+Small pull requests are strongly preferred over large ones.
+
+---
+
+## Coding Guidelines
+
+Please follow the existing Bitcoin Core coding style.
+
+When making changes:
+
+- avoid unnecessary complexity
+- keep commits focused on a single task
+- update documentation when appropriate
+- remove obsolete code instead of leaving dead paths
+- avoid introducing project-specific workarounds unless required
+
+---
+
+## Consensus Changes
+
+Consensus changes require extra care.
+
+Before proposing a consensus modification:
+
+- document the motivation
+- consider compatibility implications
+- verify the impact on wallets, pools, explorers, and nodes
+- include appropriate tests whenever practical
+
+Consensus changes should remain rare.
+
+---
+
+## Pull Requests
+
+Good pull requests generally:
+
+- solve one problem
+- build successfully
+- include clear commit messages
+- avoid unrelated formatting changes
+- keep the diff as small as practical
+
+---
+
+## Code Review
+
+Every change should be reviewed for:
+
+- correctness
+- readability
+- maintainability
+- performance
+- security
+- compatibility with upstream Bitcoin Core
+
+---
+
+## Release Process
+
+Stable releases should only be created after:
+
+- successful builds on supported platforms
+- passing test suites
+- review of consensus-related changes
+- verification of release binaries
+
+---
+

+# Vexta Core
+
+Vexta Core is the reference implementation of the Vexta blockchain.
+
+## Overview
+
+Vexta is a UTXO-based proof-of-work blockchain built on the Bitcoin Core architecture. It uses a single SHA256D mining algorithm, 10-minute block times, and a Bitcoin-style subsidy halving schedule.
+
+## Network Parameters
+
+- Consensus: Proof of Work (SHA256D)
+- Target block time: 10 minutes
+- Initial block reward: 50 VTX
+- Subsidy halving interval: 210,240 blocks
+- SegWit: Enabled
+- Taproot: Enabled
+
+## Building
+
+Build instructions are available in [INSTALL.md](INSTALL.md).
+
+Typical build process:
+
+```bash
+./autogen.sh
+./configure
+make -j$(nproc)
+```
+
+## Testing
+
+Run the unit tests:
+
+```bash
+make check
+```
+
+Functional tests are located in `test/functional`.
+
+## Contributing
+
+Contributions are welcome. Changes should prioritize stability, compatibility, maintainability, and minimal divergence from upstream Bitcoin Core whenever practical.

+# SYNOPSIS
+#
+#   AX_BOOST_BASE([MINIMUM-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
+#
+# DESCRIPTION
+#
+#   Test for the Boost C++ libraries of a particular version (or newer)
+#
+#   If no path to the installed boost library is given the macro searchs
+#   under /usr, /usr/local, /opt, /opt/local and /opt/homebrew and evaluates the
+#   $BOOST_ROOT environment variable. Further documentation is available at
+#   <http://randspringer.de/boost/index.html>.
+#
+#   This macro calls:
+#
+#     AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS)
+#
+#   And sets:
+#
+#     HAVE_BOOST

+# SYNOPSIS
+#
+#   AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])
+#
+# DESCRIPTION
+#
+#   Check whether the given FLAG works with the current language's compiler
+#   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 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' (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.

+# SYNOPSIS
+#
+#   AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+#   This macro figures out how to build C programs using POSIX threads. It
+#   sets the PTHREAD_LIBS output variable to the threads library and linker
+#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+#   flags that are needed. (The user can also force certain compiler
+#   flags/libs to be tested by setting these environment variables.)
+#
+#   Also sets PTHREAD_CC to any special C compiler that is needed for
+#   multi-threaded programs (defaults to the value of CC otherwise). (This
+#   is necessary on AIX to use the special cc_r compiler alias.)
+#
+#   NOTE: You are assumed to not only compile your program with these flags,
+#   but also to link with them as well. For example, you might link with

+#   Please let the authors know if this macro fails on any platform, or if

+Building DigiByte Core with Visual Studio
+========================================
+
+Introduction
+---------------------
+Solution and project files to build the DigiByte Core applications `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).
+
+Building with Visual Studio is an alternative to the Linux based [cross-compiler build](https://github.com/digibyte/digibyte/blob/master/doc/build-windows.md).
+
+Quick Start
+---------------------
+The minimal steps required to build DigiByte Core with the msbuild toolchain are below. More detailed instructions are contained in the following sections.
+
+```
+cd build_msvc
+py -3 msvc-autogen.py
+msbuild /m digibyte.sln /p:Platform=x64 /p:Configuration=Release /t:build
+```
+
+Dependencies
+---------------------
+A number of [open source libraries](https://github.com/digibyte/digibyte/blob/master/doc/dependencies.md) are required in order to be able to build DigiByte 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/digibyte/digibyte/blob/master/doc/dependencies.md) required for building are listed in the `build_msvc/vcpkg.json` file. To ensure `msbuild` project files automatically install the `vcpkg` dependencies use:
+
+```
+vcpkg integrate install
+```
+
+Qt
+---------------------
+In order to build DigiByte Core a static build of Qt is required. The runtime library version (e.g. v142) and platform type (x86 or x64) must also match.
+
+Some prebuilt x64 versions of Qt can be downloaded from [here](https://github.com/sipsorcery/qt_win_binary/releases). Please be aware these downloads are NOT officially sanctioned by DigiByte Core and are provided for developer convenience only. They should NOT be used for builds that will be used in a production environment or with real funds.
+
+To determine which Qt prebuilt version to download open the `.appveyor.yml` file and note the `QT_DOWNLOAD_URL`. When extracting the zip file the destination path must be set to `C:\`. This is due to the way that Qt includes, libraries and tools use internal paths.
+
+To build DigiByte Core without Qt unload or disable the `digibyte-qt`, `libdigibyte_qt` and `test_digibyte-qt` projects.
+
+Building
+---------------------
+The instructions below use `vcpkg` to install the dependencies.
+
+- Install [`vcpkg`](https://github.com/Microsoft/vcpkg).
+
+- 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.
+
+- To build from the command line with the Visual Studio 2019 toolchain use:
+
+```
+msbuild /m digibyte.sln /p:Platform=x64 /p:Configuration=Release /t:build
+```
+
+- Alternatively, open the `build_msvc/digibyte.sln` file in Visual Studio 2019.
+
+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 DigiByte Core and then configure a new AppVeyor Project pointing to the forked repository.
+
+For safety reasons the DigiByte 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 digibyte-%APPVEYOR_BUILD_VERSION%.zip %APPVEYOR_BUILD_FOLDER%\build_msvc\%platform%\%configuration%\*.exe
+    #- path: digibyte-%APPVEYOR_BUILD_VERSION%.zip
+```
+
+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 DigiByte Core more secure. When building DigiByte 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 `digibyted` has `RandomizedBaseAddress` enabled or disabled run
+
+```
+.\dumpbin.exe /headers src/digibyted.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
+
+    ```bash
+    sudo apt install docker.io bash
+    ```
+
+To run the default test stage,
+
+    ```bash
+    ./ci/test_run_all.sh
+    ```
+
+To run the test stage with a specific configuration,
+
+    ```bash
+    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,
+
+    ```bash
+    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
+
+### 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 #7: sleeping 19.2 seconds
+    y u no work
+    Before retry #8: sleeping 38.4 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
