key properties:
1. everyone can be a registar. your localhost too
2. blockchain proof of ownership and discovery (certs, not proof-of-work, fast and cheap ledger)
3. everyone can be a CA (self-signed certs pinned in blockchain)
4. no fixation on static IPs (inspired by Cloudflare Tunnels, Tailscale). IPs are ephemeral.
5. blockchain/P2P discovery of domains
but it is all fantasy without real browsers support (Chrome, Safari). 99.999% of traffic is locked there, and both controlled by monopolies Google / Apple. and you cannot even build your own browser (Apple App Store will not allow it). Maybe alternative stores and some proxies / translation layer from normal web to this web would help.
