Issue summary
It turns out a Forest node (v0.19.0) is not a able to bootstrap a Lotus node. It can, however, bootstrap another Forest node.
To reproduce on calibnet:
- Start a Forest node, grab it's multiaddr with peer id.
- Compile Lotus with the above as bootstrap node (make sure to set
LOTUS_SYNC_BOOTSTRAP_PEERS=1)
- With
lotus net peers observe that the only peer it is connected to is the bootstrap node, whereas forest-cli net peers shows way more peers.
Similarly, do the same with another Forest and observe that the second instance has many other peers.
This behaviour might stem from the fact that the peer exchange is not implemented in gossipsub in rust-libp2p ( code mention and issue) while explicitly enabled in Lotus.
Does peer exchange over Kademlia and Identify not work in Lotus? If so, can this be mitigated? The alternative would be implementing peer exchange in gossipsub, which to my understanding, is not a trivial task.
To work on this, and ensure it doesn't break in the future, once fixed, we also need a CI job to check Forest-bootstrapper compatibility with Lotus (and another Forest).
