@Revertron @erlend This is a trust model of a fediverse server. People may dislike authority when there is only one name database, but there could be hundreds of them.
Blockchains are usually engineered with an assumption of powerful global adversary. That makes sense for a financial system, but not so much for identity. The system that I want is closer to a regular server, it only needs enough redundancy to survive a hardware failure and an admin who forgot to renew the domain name.
