Light Nodes
When a light node is requesting data from the network - it will not benefit from plausible deniability. This is because a light node does not forward on behalf of other nodes, and so it is always the originator of the request.
Configuration
To run Bee as a light node full-node must be set to false and swap-enable must be set to true, and a stable Gnosis Chain RPC endpoint URL must be specified with blockchain-rpc-endpoint in the configuration.
Mode of Operation
At present, light mode represents a pragmatic and elegant approach to improving network stability, reliability and resilience.
In general, light mode may be thought of as simply not participating in the activity of forwarding or storing chunks for other members of the swarm, these nodes are strictly consumers, who will pay xBZZ in return for services rendered by full nodes - those contributing towards moving data around the network.
This means that although the node will participate in the pull syncing protocol by filling up its local storage with the chunks closest to its overlay address, the node will not serve these chunks to other peers.
Additionally, a light node will not participate in the forwarding protocol, as it will not forward chunks to peers closer to the destination address.
