ICMF configuration

In addition, you need to set up the ICMF configuration to listen to the following topics:

From the anchoring chain:

G_node_availability_report

From the directory chain:

L_create_cluster_error
L_ticket_container_result
L_cluster_update
L_provider_update
L_provider_auth_update
L_node_update
L_cluster_node_update
L_token_price_changed
L_blockchain_rid_topic
L_subnode_image_update
L_cluster_subnode_image_update

From the EVM transaction submitter chain:

G_evm_transaction_submitter_cost_topic

EIF configuration

The economy chain configuration also includes the configuration for EIF.
