The cross-chain bridge between Polkadot and Kusama is now live

It was announced that the cross-chain bridge between Polkadot and Kusama has gone live. The GRANDPA light client running on BridgeHub for both Polkadot and Kusama has been initialized, and is currently being synchronised in real-time by an unlicensed relay operated by Parity. The consensus proof logic (light client), parallel chain header proof logic, and message proof logic all run on the in-chain when BridgeHub is running, and are exclusively controlled by Polkadot/Kusama governance.
