Sounds like you should just use libp2p (which is what IPFS is using for P2P networking) in whatever flavor you're building your blockchain with! At least you still have the same bootstrapping technology you're doing now, but with the added benefit of peers exchanging existing connections when new peers connects :)
I’ll check it out! Fwiw I work on Cardano but higher up the stack than networking, so I’m not 100% sure what happens there except for what I see as a ‘user’ of it.
