Governance

• Orbit Bridge defines Governance on each chain on the basis of their respective vault.

• The Origin Chain's vault is created with a Multi-Sig wallet, so if there is no governance concensus, no assets can be moved.

• Governance has mint/burn/execute permissions on the Destination chain

• A pair of what destination chain to bridge must be registered.

• Depend on specification of each chain governance have different consensus in same governance.
