تجميع داش كور¶
While Dash offers stable binary builds on the website and on GitHub, and development builds using GitLab CI, many users will also be interested in building Dash binaries for themselves. This process has been greatly simplified with the release of Dash Core 0.13.0, and users who do not required deterministic builds can typically follow the generic build notes available on GitHub to compile or cross-compile Dash for any platform.
The instructions to build Dash Core 0.12.3 or older are available here on a previous version of this page.
Gitian هي عملية البناء الحتمية التي تُستخدم لإنشاء الملفات التنفيذية الأساسية في داش. ويوفر طريقة للتأكد بشكل معقول من أن الملفات التنفيذية مبنية بالفعل من المصدر على GitHub. كما أنه يضمن أن نفس التبعيات التي تم اختبارها قد تم استخدامها وتم دمجها بشكل ثابت في الملف القابل للتنفيذ. يقوم المطورون المتعددون ببناء الشفرة المصدرية باتباع واصف محدد ("وصفة") ، وتوقيع النتيجة مشفرًا ، وتحميل التوقيع الناتج. تتم مقارنة هذه النتائج وفقط في حالة تطابقها ، يتم قبول الإنشاء وتحميله إلى dash.org.
This setup has been tested using a clean install of Ubuntu 20.04. Start by
logging in as the "root" user. Create a new user with the following command,
<username> with a username of your choice:
You will be prompted for a password. Enter and confirm using a new password (different to your root password) and store it in a safe place. You will also see prompts for user information, but this can be left blank. Alternatively, an existing user can be used on systems that are already in use (e.g. your existing development system).
docker group on the system. This group will be used by Docker
processes and also will enable non-root users to run the Docker commands used by
the build process:
Add the user to the sudo and docker groups so they can perform commands as root and run docker commands:
usermod -aG sudo,docker <username>
While still logged in as root, update the system from the Ubuntu package repository:
apt update apt upgrade -y
apt install -y apt-cacher-ng
No when asked
Allow HTTP tunnels through Apt-Cacher NG? during
Note: you may also need to open port 3142 if you have a firewall enabled on
your system (e.g.
ufw allow 3142/tcp).
After installing these updates, reboot the system, login as
clone required repositories:
git clone https://github.com/dashpay/dash git clone https://github.com/devrandom/gitian-builder git clone https://github.com/dashpay/dash-detached-sigs git clone https://github.com/dashpay/gitian.sigs
Download the Mac OSX SDK:
mkdir gitian-builder/inputs wget -q -O gitian-builder/inputs/MacOSX10.11.sdk.tar.gz https://bitcoincore.org/depends-sources/sdks/MacOSX10.11.sdk.tar.gz
It is only necessary to run this step during the initial setup of your machine:
# <signer> = The name associated with your PGP key # <version> = Dash Core tag to build (exclude the leading "v") # Example: ./dash/contrib/gitian-build.py --setup alice 0.17.0.3 ./dash/contrib/gitian-build.py --setup <signer> <version>
signer parameter should be set to the value provided for "Real name"
when generating a key with GPG. See the GnuPrivacyGuard Howto
for details on how to generate a key if you don't already have one.
Build Dash Core¶
Run gitian build to create binaries for Linux, Mac, and Windows:
# <signer> = The name associated with your PGP key # <version> = Dash Core tag to build (exclude the leading "v") # Example: Build binaries for all OSes, use all available cores and 16 GB RAM # ./dash/contrib/gitian-build.py -b -n -j $(nproc) -m 16000 alice 0.17.0.3 ./dash/contrib/gitian-build.py -b -n -j $(nproc) -m <MB of RAM to use> <signer> <version>
These instructions assume that a PGP key for <signer> exists on the build system. If the expected key is not found, the script will fail at the signing step with a message including:
gpg: skipped "<signer>": No secret key gpg: signing failed: No secret key
When the build completes, it will put the binaries in a
.assert files and their signatures will be placed in
Create signatures for signed binaries¶
Mac and Windows binaries are signed by Dash Core Group using the relevant
Apple/Microsoft processes. In this step, that information will be validated and
signed by your machine. The associated
.assert files and their signatures
will be placed in
gitian.sigs/<version>/<signer>/... along with the
signatures for unsigned binaries created in the previous step.
# <signer> = The name associated with your PGP key # <version> = Dash Core tag to build (exclude the leading "v") # Example: ./dash/contrib/gitian-build.py -s -n -j $(nproc) -m 16000 -o mw alice 0.17.0.3 ./dash/contrib/gitian-build.py -s -n -j $(nproc) -m <MB of RAM to use> -o mw <signer> <version>
The gitian.sigs repository contains deterministic build results signed by multiple Core developers for each release. Run the following command to verify that your build matches the official release:
# Example: ./dash/contrib/gitian-build.py -v alice 0.17.0.3 ./dash/contrib/gitian-build.py -v <signer> <version>
You should get a result similar to the following for Linux, Windows, MacOS,
Signed Windows, and Signed MacOS. Assuming the previous steps completed
successfully, you will also see your own signatures with an
OK status also.

After successfully building the binaries, signing them, and verifying the signatures, you can optionally contribute them to the gitian.sigs repository via a pull request on GitHub.
Since the official gitian.sigs repository has restricted write access, create a fork of it via GitHub and add your fork as a remote repository:
git remote add me https://github.com/<your GitHub username>/gitian.sigs
The first time you contribute signatures, also put a copy of your public key in
gitian-keys folder of the repository so others can easily verify your
signature. Your public key can be exported to a file using the following
# <signer> = The name associated with your PGP key # Example: gpg --output alice.pgp --armor --export alice gpg --output <signer>.pgp --armor --export <signer>
Adding your signatures¶
Create a new branch for the version that was built:
# Example: git checkout -b 0.17.0.3-alice git checkout -b <version>-<signer>
Add and commit the
*.assert.sig files created by the build
process. They will be located in the following folders:
<version>-linux/<signer>/* <version>-osx-signed/<signer>/* <version>-osx-unsigned/<signer>/* <version>-win-signed/<signer>/* <version>-win-unsigned/<signer>/*
Push to your fork of the gitian.sigs repository on GitHub:
# "me" references the name of the remote repository added during initial setup git push me
Go to GitHub and open a pull
request to the
master branch of the upstream repository. The pull request
will be reviewed by Dash Core developers and merged if everything checks out.
Thanks for contributing!
