How to create swarm with Gossipsub behaviour which blocks anybody except specified list of peers?

[Velnbur]

As I understand there is only one whitelist option available, and only for topics. But how I can do the same for Peer Ids without implementing it by myself by handling these "connection" events and immediately disconnecting them?

[elenaf9]

There is an independent, more generic network behavior allow_block_list, that only permits connections to whitelisted peers. Does that help?

Thank you!

If you simply want to disconnect from the peers that you have no interest with, use libp2p-allow-block-list, or try libp2p-pnet. But if you just want to skip the negotiation of the protocol you'll need to tinker with your NetworkBehaviour, likely with your own implementation of NetworkBehaviour trait without the derive macro.
