Alright so I’m not an expert so I might not be explaining it correctly.
Federated Network: Multiple instances sharing content, such as Lemmy
Peer to Peer Network: There is no “instances”, just peers. Many peers sharing content. Every user is a peer. There is no server costs, because every device connected to the network is acting like a mini-server. It will cost your device some storage space and network bandwith depending on the how the software is designed.
Or do you think Centralized servers are still gonna dominate the future?
I wish to see a P2P network with moderation “subscriptions”! So you can subscribe to the “anti-spam list” or “!asklemmy moderation list by @mekhos” or “anti-xenophobic list”. The integrity of each filter list is upheld by its reputation. If a spam list flags too many legitimate users, people have the choice to abandon it. If users of a community (which is just a hashtag) don’t like the direction the mods are steering it, they can resubscribe to a different set of mods.
Bluesky does this.
The atProtocol has some pretty cool things. I hope ActivityPub can adopt the ability for users to invite others so closed instances can have an invite system
I think ultimately something like that will be the solution. And maybe it will just be that you can subscribe to any other user’s block list, and perhaps they can in turn subscribe to yours, and basically within your peer 2 peer network the block list(s) are federated. You could potentially even have a block and whitelist where when someone you think shouldn’t get blocked gets blocked you personally white list them, and in the case of conflicting block and whitelists, a consensus based confidence list is created where some users just don’t show in your feed if enough percentage of your block list follows block them vs whitelist them, and users near 50% show in your feed in a collapsed “controversial” mode
