Binary Releases

Binary releases are available from the releases page. Binary builds that track the latest changes on the master branch are available on Dockerhub using the develop version or as binary downloads (tar.gz format or zip format).

We recommend only using release versions for Mainnet, but develop builds are useful for testing the latest changes on testnets.

Release notifications are available via:

Build Instructions

Install Prerequisites

  • Java 11+

Note: Official builds of Teku are performed with Java 11. Building on a more recent version of Java is supported, but the resulting build will not work on earlier versions of Java.

Build and Dist

To create a ready to run distribution:

git clone https://github.com/ConsenSys/teku.git
cd teku && ./gradlew distTar installDist

This produces:

  • Fully packaged distribution in build/distributions
  • Expanded distribution, ready to run in build/install/teku

Build and Test

To build, clone this repo and run with gradle:

git clone https://github.com/ConsenSys/teku.git
cd teku && ./gradlew

After a successful build, distribution packages are available in build/distributions.

Other Useful Gradle Targets

Target Builds
distTar Full distribution in build/distributions (as .tar.gz)
distZip Full distribution in build/distributions (as .zip)
installDist Expanded distribution in build/install/teku
distDocker The consensys/teku docker image

Code Style

We use Google's Java coding conventions for the project. To reformat code, run:

./gradlew spotlessApply

Code style is checked automatically during a build.

Testing

All the unit tests are run as part of the build, but can be explicitly triggered with:

./gradlew test
