Bridge-hubs Parachain
Implementation of BridgeHub, a blockchain to support message passing between Substrate based chains like Polkadot and Kusama networks.
BridgeHub allows users to:
- Passing arbitrary messages between different Substrate chains (Polkadot <-> Kusama). -- Message passing is
BridgeHub is meant to be system parachain with main responsibilities:
- sync finality proofs between relay chains
- sync finality proofs between BridgeHub parachains
- pass (XCM) messages between different BridgeHub parachains
