Network

Represents a blockchain network.

Description

A Network object contains the desired configuration of a blockchain network and reports its ongoing status via status.

To provision a network, create a network object. The following request will create an Ethereum network with default configurations and install the Chainlink and The Graph plugins:

POST /v1alpha/networks
Content-Type: application/json

{
    "metadata": {
        "name": "octonet"
    },
    "spec": {
        "chain": {
            "type": "Ethereum",
            "ethereum": {
                "plugins": {
                    "chainlink": {},
                    "graph": {}
                }
            }
        }
    }
}

The server responds immediately with 201 Created and background controllers will start the provisioning process. For a full list of supported blockchain platforms and their respective plugins, see Supported chains and plugins.

You may request the network you just created:

GET /v1alpha/networks/{id}

And the server responds with:

{
    "kind": "Network",
    "version": "v1alpha",
    "metadata": {
        "name": "octonet",
        "rev": 1,
        "ownerID": <owner_id>,
        "createdAt": "2025-07-14T23:48:01.153Z",
        "updatedAt": "2025-07-14T23:48:01.153Z",
    },
    "spec": {
        "chain": {
            "type": "Ethereum",
            "ethereum": {
                // ...
            }
        }
    },
    "status": {
        "state": "Pending",
        "message": "Provisioning network",
        "execution": {
            "currentStep": 15,
            "totalSteps": 56,
        },
        "chainSpecHash": "...",
        "lastActivityAt": "2025-07-14T23:48:01.153Z",
        "lastWakeUpAt": "2025-07-14T23:48:01.153Z"
    }
}

Notice how the network status is reported under status.

If you are using forked networks and want to resync to the latest block height, you may send an update network request with spec.maintenanceRequest:

PUT /v1alpha/networks/{id}
Content-Type: application/json

{
    "metadata": {
        "name": "octonet"
    },
    "spec": {
        "chain": {
            "type": "Ethereum",
            "ethereum": {
                "plugins": {
                    "chainlink": {},
                    "graph": {}
                }
            }
        },
        "maintenanceRequest": {
            "action": "Resync",
            "nonce": 1
        }
    }
}

Note that nonce must be different from status.observedMaintenanceNonce (0 if not set) for the maintenance action to be applied.

If you no longer need a network, you may delete it:

DELETE /v1alpha/networks/{id}

Persistent network

By default, networks stop shortly after 24 hours since the last wake up. Any activity one the network (viewing, updating, using endpoints) will cause the network to be restarted. At the moment, all data on the network will be lost.

To have networks running permanently with stronger guarantees, set spec.persistent to true, subject to your quota limits. For more information about quotas, see Quota. Persistent networks may take longer to provision due to higher compute constraints.
