That is very interesting spec, but also alarming. It contains:

> The meshsub router offers a baseline construction with good amplification control properties, which we augment with gossip about message flow.

This is notoriously hard to get right. How to prevent spam, posioning or Sybils in your gossip network? Scientific work on p2p overlays and gossip is hard to publish now at venues like Usenix or NSDI. After Newscast from 2003 it seems you need strong identity to make these systems attack resilient. An unsolved problem.

Thank you for this insight! We will put a university student team on exploring this likely vulnerability in IPFS/libp2p.
