Delivering the bits is not the hard part of making a successful video platform. It's other stuff like recommendations and content discovery that is actually useful, allowing creators to monetize enough that they want to be on your platform, navigating legal issues, fighting spam and abuse, and getting enough users to sign up and start using your service.

Peer to peer died because (1) a lot of the world, especially outside the US, has terrible upload/bandwidth, (2) HTTPS CDNs got _really_ cheap, far cheaper that p2p technologies like BitTorrent+WebSeed.

There are a minority of users who care about being able to host videos that violate YouTube/TikTok/Instagram policies. Unfortunately, a significant part of that minority is working with infringing or illegal content, which both prevents ad networks from working with you and attracts attention from law enforcement.

Pretty much worse user experience guaranteed, plz no.

That would put users at risk of being sued/punished for copyright infrigement.

this is exactly why i worked on webtorrent ~13 years ago https://github.com/webtorrent/webtorrent

there exist distributed alternatives like joinpeertube.org but they never really take off. Consumers like centralization, look at twitter.

yes, will you also be providing the caching server? Because that's the main blocker I think, nobody has the resources to cache them.

I honestly don't see how those two things are related.

The problem with P2P video is that it's expensive to host and most of the people using it are going to use it for child abuse. It makes it not realistic.
