Does this run a mini IPFS node on the sender and relayer and rely instead on the IPFS network being up to propagate the DHT changes through the network?
It’s just running a very lightweight libp2p host that speaks the DHT protocol. It’s basically just taking the bare minimum part of Kubo (IPFS) that’s necessary to interact with the DHT.
It’s then relying on the rest of the IPFS network to propagate the record for discovering the sender and receiver.
