ISMP GRANDPA Consensus Client

This allows standalone chains communicate with Hyperbridge over ISMP.

The consensus client relies on a pallet which stores a list of parachains and State machine identifiers authorized to use this client.

Overview

The Pallet allows the AdminOrigin configured in pallet-ismp to dispatch calls for adding and removing substrate-based chains from the pallet whitelist.

Setting up

When using this consensus client the following should be done in order:

• Create the consensus state using create_consensus_client

• The supported state machine identifiers should be whitelisted in the pallet by calling add_state_machines from the AdminOrigin.
  

Note

If a state machine identifier is not found in the whitelist, ismp datagrams from that chain will be rejected.

Dispatchable Functions

• add_state_machines - Adds some standalone chain state machine identifiers to the whitelist.
• remove_state_machines - Removes some standalone chain state machine identifiers from the whitelist.
