Runtimes

This repository houses the code required to build the runtimes for Polkadot, Kusama, and their System-Parachains. Its maintenance is overseen by the Fellowship, as decreed by the Polkadot and Kusama Governance. The primary objective is to provide excellent code, which can subsequently be enacted on-chain through a decentralized referendum.

Structure

Each leaf folder contains one runtime crate:

├── relay
│   ├── kusama
│   └── polkadot
└── system-parachains
    ├── asset-hubs
    │   ├── asset-hub-kusama
    │   └── asset-hub-polkadot
    ├── bridge-hubs
    │   ├── bridge-hub-kusama
    │   └── bridge-hub-polkadot
    ├── collectives
    │   └── collectives-polkadot
    └── gluttons
        └── glutton-kusama

Approval rights

The approval rights are configured in review-bot.yml. The rights are configured as:

• All files in .github require two approvals from Fellowship members of rank 4 or higher.
• CHANGELOG.md, relay/* or system-parachains/* require four approvals from Fellowship members of rank 3 or higher.
• All other files require the approval from one Fellowship member of rank 2 or higher.

The review-bot uses the on-chain identity to map from a GitHub account to a Fellowship member. This requires that each Fellowship member add their GitHub handle to their on-chain identity. Check here for instructions.

• Official List of Fellows
• List of Fellows with their GitHub handles

Working on Pull Requests

To merge a pull request, we use Auto Merge Bot.

To use it, write a comment in a PR that says:

/merge

This will enable auto-merge in the Pull Request (or merge it if it is ready to merge).

The automation can be triggered by the author of the PR or any fellow whose GitHub handle is part of their identity.

Release process

Releases are automatically pushed on commits merged to master that fulfill the following requirements:

• The CHANGELOG.md file was modified.
• The latest version (the version at the top of the file) in CHANGELOG.md has no tag in the repository.

The release process is building all runtimes and then puts them into a release in this github repository.

The format of CHANGELOG.md is based on Keep a Changelog.

Communication channels

The Fellowship is using Matrix for communication. Right now there exists two channels:

• Polkadot Technical Fellowship Channel: The channel for all Fellowship members to discuss. To get voice rights, you need to be part of the Fellowship. However, the channel is readable by anyone.
• Polkadot Technical Fellowship - Open Channel: Open channel for anyone. Should be used to reach out to the Fellowship e.g. to request review or help on a topic.
