Welcome to the open-source implementation of SCION (Scalability, Control and Isolation On next-generation Networks), a future Internet architecture. SCION provides route control, failure isolation, and explicit trust information for end-to-end communication. To find out more about the project, please visit our documentation site.


Installation packages for Debian and derivatives are available for x86-64, arm64, x86-32 and arm. These packages can be found in the latest release. Packages for in-development versions can be found from the latest nightly build.

Alternatively, "naked" pre-built binaries are available for Linux x86-64 and can be downloaded from the latest release or the latest nightly build.

Build from sources

SCION can be built with go build. To build all binaries used in a SCION deployment (i.e. excluding the testing and development tools), run

CGO_ENABLED=0 go build -o bin ./router/... ./control/... ./dispatcher/... ./daemon/... ./scion/... ./scion-pki/... ./gateway/...

The default way to build SCION, however, uses Bazel. In particular, this allows to run all the tests, linters etc. Please visit our documentation site for instructions on how to set up Bazel and the full development environment.

Connecting to the SCION Network

Join SCIONLab if you're interested in playing with SCION in an operational global test deployment of SCION.
