Promotion process overview

• Git issues to record new features or bug fixes

• Git branches to isolate proposed modifications

• Git GPG to sign every commit and tag

• Pull requests to enforce governance

Promotion Process

Constraints

Every code change is tied to a change request

Developers sign their modification using GPG

Master branch integrity is preserved by the pull request process

The pipeline builds and tests the code for pull requests

The pipeline publishes the smart contract to the artifact repository when changes are tagged

Each organization receives a notification when a new version is available
