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.
