Matrix://…, Fabric://…, Nostr://…, XYZ.com://…—we could imagine different P2P and centralized networks working in parallel.
But what is the very first handshake protocol? In Web2, it’s HTTP or HTTPS, both of which are easily blocked by the Great Firewall or DNS attacks.
We can speculate on two possible solutions:
1. You register your NAS as active, along with its protocol, with BPoS SuperNodes. These SuperNodes reach a consensus, and any client trying to contact your NAS would randomly query a few BPoS SuperNodes to locate it. I believe a similar approach is used by Carrier v2.
2. You propagate your DID, including a phone number (for free messaging), email, social network messaging handles, etc., on the DID chain. Since any client’s NAS could have a copy of this ledger, it could send an initial Ping message using any contact handle to negotiate a private protocol for the upcoming communication.
The key is to abstract all protocols using an OS-level network drive and to give users the choice of whether to publish their social connection handles. In an extreme case, one could even download an entire movie using the email protocol. If no contact information is published on the DID chain, the default first handshake could simply be a DHT adopted by Carrier v2.
I hope it’s now clear that this blockchain, that blockchain—this protocol, that protocol—they all have their merits and shortcomings and face competition in the market.
