Aaah yes that sounds like a bit of a burden. Those are p2p networks that put a lot of load on the peer and scale extremely poorly overall.

Kademlia DHTs like IPFS or Bittorrent scale medium well.

It's a question of scaling distributed systems -- my eternal pet peeve, I'm optimistic! -- but not a question of formats or key algos or diverging code bases which is what this conversation was about.
