Scaling Gossip with Bundles

Hubs are running into scaling issues with libp2p. We're proposing a change to "bundle" messages to fix some of these issues. 

This may add a ~1s delay to casts moving between clients.

If the goal is to reduce the gossip emission rate have you tried to reduce the gossip history window and gossip factor rate ?

I have very little knowledge of how farcaster hubs work but bundles seems pretty similar as a construct

That makes sense,  in the ethereum consensus layer we do have a similar issue with 3000 unique attestations being propagated about per second. So we have a construct called aggregates which batch information from them. This helps greatly in reducing bandwidth requirements for a node

Yes! If the window becomes too small, we end up with lots of duplicate messages being gossiped because some hubs rebroadcast the messages after the window. Same with the factor rate.
