Contributions & Code of Conduct

Please follow the contributions guidelines as outlined in docs/CONTRIBUTING.adoc. In all communications and contributions, this project follows the Contributor Covenant Code of Conduct.


The security policy and procedures can be found in docs/SECURITY.md.


The reason for the split-licensing is to ensure that for the vast majority of teams using Substrate to create feature-chains, then all changes can be made entirely in Apache2-licensed code, allowing teams full freedom over what and how they release and giving licensing clarity to commercial teams.

In the interests of the community, we require any deeper improvements made to Substrate's core logic (e.g. Substrate's internal consensus, crypto or database code) to be contributed back so everyone can benefit.
