Light Push FURPS

Functionality

1. Enables light nodes to push messages to service nodes for relay to the network.
2. Requests service nodes to publish messages to WAKU2-RELAY shards.
3. Provides confirmation that a message has been received by at least one node.
4. Supports comprehensive error codes for various failure scenarios.

Usability

1. Implements simple async request/response pattern.
2. Uses standard Waku Message format.
3. Only requires an established libp2p connection.
4. Provides descriptive error messages in responses.

Reliability

1. Implements DoS protection through request rate limitation.
2. Status codes indicate the best recovery method (retry, discard service node or irrecoverable failure).
3. 80% message transmission success rate on live Status network (service node from both Status Desktop and fleet Waku instances)

Performance

1. Only one network round trip is required per operation; including both configuration and message transmission.
2. Minimizes protocol overhead for efficient resource usage.

Supportability

1. Linux amd64 CLI as service node
2. Browser as client
