Only via centralized services.
The best compromise is NIP05 identities tied to a domain well known that you control. Hence the reason that I tie mine to nodeyez.com and not nostrplebs.com
In this context, nostrplebs.com is obviously way more centralized than nodeyez.com, and since I don't have any control over nostrplebs, I put less trust in the accounts that NIP05 with it.
aren’t those servers that you’d host your own site on, still centralised?
You can host a web server from your house. The real issue is that DNS itself is centralized.
How about we create an OP_RETURN that associates a username to a nostr pubkey and its carved in the block chain in perpetuity. Order of blocks and txid denotes first in the case of multiple for same name. We'll define it as a layer 2 and formulate both a BIP and NIP around it, and it'll spend months behind the gatekeepers of BIP approval as "not in the spirit of bitcoin" and there will be a mad rush to fill blocks with op_returns registering to generated pubkeys for sale. /sarcasm
Or we just do what were doing now. Treat names as temporary and short time preference, and build reputations instead
