How it works

Nodes communicate with each other using the NodeToNode service defined in the protocol. The envelope is received through the NodeToNode.NewEventReceived RPC from the node that is processing the StreamService.AddEvent client RPC request. The node verifies if the action is permitted, by validating the signature of the event. The event is then added to the minipool of the stream and committed to local storage. A success response is sent to the NodeToNode.NewEventReceived RPC. A NodeToNode.NewEventInPool message, containing the event hash, is broadcast to the stream node, excluding the original NodeToNode.NewEventReceived RPC caller. Once a majority of minipools contain the event, the event is sent to any client monitoring the given stream through a Sync RPC call.
  • The number of minipools is calculated by counting the local minipool and the number of NodeToNode.NewEventInPool messages received.
