Obviously Lemmy, Mastodon, Pixelfed, etc. are federated decentralized equivalent to their centralized counterparts, but what is the counterpart in the fediverse to TikTok? It is a dominant app for millions of people, and as far as I can tell the closest thing is Peertube, but isn’t that more of a YouTube equivalent? Does it not exist because the bandwidth and storage costs are just too great? Or because the algorithmic nature of content selection is inherently anti-fediverse in some way? Clearly many people choose to interact with each other this way, but it seems like a gap in the fediverse and I was wondering why.
Peertube as you said is the closest equivalent as a video distributor. Technically a similar approach to Peertube would work by using both Torrents and Instance data storage. Now what makes Tik Tok so popular is its algorithm, which mind you, is a tiny wee bit manipulative. In future, Peer Tube might implement something like dedicated sections for vertical videos. But without a significant cultural shift, I’m not seeing an effective Tik Tok clone appear without a lot of noses being turned up.
IMO, anything based on peer-to-peer sharing is a nonstarter, not with the kind of video bandwidth demands that a TikTok or equivalent would put on cell phone networks. You might get it working on desktop, but I’d bet good money that the cell networks & Apple & Google would move to lock that s*** down ASAP.
