set by the client. Clients may specify either:
* `{"commitment":"max"}` - the node will query the most recent bank confirmed by the cluster as having reached `MAX_LOCKOUT_HISTORY` confirmations
* `{"commitment":"root"}` - the node will query the most recent bank having reached `MAX_LOCKOUT_HISTORY` confirmations on this node
* `{"commitment":"recent"}` - the node will query its most recent bank state
* `{"commitment":"single"}` - the node will query the most recent bank having reached 1 confirmation
* `{"commitment":"recent"}` - the node will query its most recent bank
The commitment parameter should be included as the last element in the `params` array:

### Subscription Websocket

After connecting to the RPC PubSub websocket at `ws://<ADDRESS>/`:
* Submit subscription requests to the websocket using the methods below
* Multiple subscriptions may be active at once
* All subscriptions take an optional `confirmations` parameter, which defines
how many confirmed blocks the node should wait before sending a notification.
The greater the number, the more likely the notification is to represent
consensus across the cluster, and the less likely it is to be affected by
forking or rollbacks. If unspecified, the default value is 0; the node will
send a notification as soon as it witnesses the event. The maximum
`confirmations` wait length is the cluster's `MAX_LOCKOUT_HISTORY`, which
represents the economic finality of the chain.
* Many subscriptions take the optional [`commitment` parameter](jsonrpc-api.md#configuring-state-commitment), defining how . For subscriptions, if commitment is unspecified, the default value is `recent`.
