Travis: Build Status Circle CI: CircleCI Codecov: Codecov License: License: GPL v3

This code is loosely based on the previous Golang prototype.

Code Status: This Rust version is alpha software -- not for production use. You should expect unstable code APIs and data chains.

NO LONGER CURRENT REPOSITORY: This version of Holochain has been replaced by a version that is more performant, stable, and secure. We suggest porting applications to the new version of Holochain which is receiving regular updates and feature enhancements.

Find releases here.
