There are 2 elements of a YouTube style client.
The organization of metadata (listings)
Actual storage
YouTube does both because it’s centralized and I don’t know if it loss leaders it’s service for other purposes or not. Haven’t checked how profitable it is.
The idea here that you can use kind 1063 and host a URL elsewhere works too.
I’m still building something that could be useful for decentralized storage though it’s far from ready for prime time.
Flare’s is probably a good start especially for bootstrapping a set up.
