Seems that gossipsub might not be ready for Round 1 : libp2p/gossipsub1.1

Base spec here: https://github.com/libp2p/specs/blob/master/pubsub/gossipsub/gossipsub-v1.0.md

Gossip 1.1 here: https://github.com/libp2p/specs/blob/master/pubsub/gossipsub/gossipsub-v1.1.md

Published paper: https://arxiv.org/pdf/2007.02754.pdf

Gossip 1.1 is basically sitting on top of 1.0 so both specs knowledge is kind of necessary.

RPC management: (within that we have validation, relevant for NBC)
