wakuWaku v2 meshsub heartbeat limits in high-churn production environments
Waku v2 uses libp2p gossipsub with meshsub for message propagation across the peer-to-peer network. While local development often runs with default heartbeat intervals, production deployments face higher peer churn and variable network conditions that can destabilize the mesh. The meshsub protocol relies on periodic heartbeat messages (IHAVE/IWANT) to mainta
Waku v2 store node retention boundaries and offline delivery guarantees
Waku v2 routes messages by content topic rather than recipient address, and store-and-forward nodes can retain messages for offline peers. However, retention is operator-configured rather than a protocol-wide guarantee, and delivery is best-effort. When no store node is available while a recipient is offline, a message may be dropped without retry. The unres
