1.  We're adding support for ENS to Hubs. i.e. you'll be able to mention ENS names

2. Fname system (which is already centralized) is moving to an off-chain ENS resolver. Goal is to offer everyone a free name when they sign up with trade off of it being less decentralized.

3. There's been a bunch of discussion on this topic here:

4. FIDs will onchain and in a non-upgradeable contract. i.e. once you have an FID, you have it forever.

Under-the-hood, the protocol is powered by FIDs. Fnames and ENS are (important!) human-readable cosmetic improvements.
