Users still could not reach the app. Two of four layers in a typical Web3 stack are decentralised, and the first one a user touches is the most centralised part of the whole thing.https://voiceban.io/blog/browser-bottleneck/https://voiceban.io/blog/browser-bottleneck/Wed, 29 Jul 2026 00:00:00 +0000Kofi Otuo"Just use libp2p" is not the answer people think it is. A browser tab can only put HTTP, WebSocket and WebRTC on the wire — and all three still end at a domain name in DNS. Which is why the ecosystem hardcoded Infura and called it done.https://voiceban.io/blog/deterministic-ipfs-discovery/https://voiceban.io/blog/deterministic-ipfs-discovery/Wed, 29 Jul 2026 00:00:00 +0000Kofi OtuoHow VoiceBan actually does it: a shared derivation function and the current time window let the frontend and the backend independently compute the same IPNS name, without ever exchanging it.
