Manage a Chain

Monitoring​

You can view the chain state using the dashboard (<URL>/wasp/dashboard when using node-docker-setup).

Manage Chain Configuration and Validators​

You can manage the chain configuration and committee of validators by interacting with the Governance contract.

The “Chain Owner” is the only one who can perform administrative tasks.

Change Chain Ownership​

To change the chain ownership, the current “Chain Owner” must call delegateChainOwnership specifying the agentID of the next owner. The next owner must call claimChainOwnership to finalize the process.

Change Access Nodes​

For new access nodes to join the network, they need to:

  • Be added as a trusted peer to at least 1 of the existing nodes.
  • Be added by the administrator to the list of access nodes by calling changeAccessNodes. There is a helper in wasp-cli to do so:
wasp-cli chain gov-change-access-nodes accept <pubkey (0x...)>

After this, new nodes should be able to sync the state and execute view queries (call view entry points).

You can remove an access node by calling changeAccessNodes.

Alternatively, you can add "non-permissioned" access nodes without the signature from the chain owner to add any node as an "access node". You can do this by using the following command:

wasp-cli chain access-nodes <add|remove> <pubkey (0x...)>

This node won't be "officially" recognized by the committee but will still be able to sync the state and provide all regular functionality.

Change the Set of Validators​

You can do this in different ways, depending on who controls the governor address from the alias output of the chain.

  • If the chain governor address is the chain committee, you can perform the rotation by calling rotateStateController after adding the next state controller via addAllowedStateControllerAddress.
  • If the chain governor address is a regular user wallet that you control, you can issue the rotation transaction using wasp-cli:
wasp-cli chain rotate <new controller address>

Or:

wasp-cli chain rotate-with-dkg --peers=<...>
