That’s a great idea but you should provide detailed explanations or at least mention the platforms you are identifying. I am a little bit familiar with them but I still had to look them up.
Peertube
PeerTube is a free and open-source, decentralized, ActivityPub federated video platform. It can use peer-to-peer technology to reduce load on individual servers when videos get popular. As an ActivityPub platform, it is part of the federated network known as the Fediverse.

Mastodon

It operates as a federated network of independently managed servers that communicate using the ActivityPub protocol, allowing users to interact across different instances within the Fediverse.
