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.
