NOSTR relies on centralized ICANN. Spaces Protocol fixes this.

It's very serious. There's a few people working on it. Mike Carson is leading the project. 2013 Bitcoiner with over 10 years in traditional domains. Park.io Here's the github: https://github.com/spacesprotocol Documents: https://spacesprotocol.org/

Spaces Protocol bypasses ICANN because it doesn't use their centralized DNS hierarchy. Instead spaces (names) are anchored directly to Bitcoin's blockchain with minimal on chain footprint. The 3600 annual cap is a protocol design feature to prevent squatting. Something that has plagued other naming systems. Everyone with a subspace has the option to do 100% of their transactions on chain if they wish and be treated the same as a parent space. https://docs.spacesprotocol.org/
