Plebbit is pure peer-to-peer social media protocol, it has no central servers, no global admins, and no way shut down communities-meaning true censorship resistance.
Unlike federated platforms, like lemmy and Mastedon, there are no instances or servers to rely on
this project was created due to wanting to give control of communication and data back to the people.
Plebbit only hosts text. Images from google and other sites can be linked/embedded in posts. This fixes the issue of hosting any nefarious content.
ENS domain are used to name communities.
Plebbit currently offers different UIs. Old reddit UI and new reddit, 4chan, and have a Blog. Plebbit intend to have an app, internet archive, wiki and twitter and Lemmy UI . Choice is important. The backend/communities are shared across clients.
anyone can contribute, build their own client, and shape the ecosystem

no global admins, and no way shut down communities-meaning true censorship resistance.
“True censorship resistance” is not a desirable property. No normal user wants to deal with moderation. You need to have a structure for delegating moderation and such tasks to other people.
@Plebbitor I could not join the matrix, please check the server is OK 😓
Good job
No moderation seems like a recipe for disaster
Well from their site
Moderation
Since there are no global admins, the administrative control of a subplebbit rests solely with its creator. No one else can moderate content or accounts unless the subplebbit creator grants them permission.
So, it’s not that theirs no moderation. It’s just “subplebbit” creator/delegates controlled as there is no over arching site wide company able to moderate it on the whole.
It will mean, as a user, you’ll have to be liberal with removing subplebbits from your own feed though. I’m sure there will be some… not so pleasant subplebbits appearing.
this project was created due to wanting to give control of communication and data back to the people
The “giving control of communication” goal seems to contradict the “viewer automatically shares without a choice” and the dependence on good-intent node owners not moderating their node content.
If a node owner hosts a community, what prevents them from moderating that community?
This again? It’s basically lemmy but less secure, stop advertising it
From the whitepaper:
- The user completes the captcha challenge and publishes his post and captcha challenge answer over pubsub.
- The subplebbit owner’s client gets notified that the user published to his pubsub, the post is not ignored because it contains a correct captcha challenge answer.
- The subplebbit owner’s client publishes a message over pubsub indicating that the captcha answer is correct or incorrect. Peers relaying too many messages with incorrect or no captcha answers get blocked to avoid DDOS of the pubsub.
- The subplebbit owner’s client updates the content of his subplebbit’s public key-based addressing automatically
I may be misunderstanding how this protocol works, but at step 10 what prevents the owner from publishing the captcha answer as incorrect as a method of censorship based on the content of the post?
The owner can obviously moderate and thereby censor, anyway. Thats not the kind of censorship free this thing advertises. Its not more or less censored as lemmy is when instance hosts do moderation.
Do you mean spamming faulty captcha answers to trigger the DDOS protection on the peers?
Technically cool, but it’s scary that it tries to emulate the anonymous, unmoderated shithole that is 4chan. Go to 4chan now and try to imagine something even more racist, nazi and unhinged.

Nowhere in the project whitepaper or FAQ does it talk about banning image hosting. Base64 encoding images in the text post is trivial, so maybe OP is the one projecting this intent or feature?
How long until this gets overrun with 🍕 and nobody wants to use it…
Not sure how moderation would even be possible with this model.
I bring this point up every time I see someone pushing the idea of P2P or federated social networks with no moderation and no one has a solution for it yet. Because there isn’t a solution.
It’s like these people don’t even want to look at existing social media with minimal moderation. It doesn’t take long on 4chan and other less reputable *chan style sites to see that no matter how much you want to shake off the chains of overbearing moderators, there is a bare minimum moderation necessary for any social media to survive.
Even social media sites on TOR have moderation.
When even the darkest, least moderated cesspools online still have some minimal moderation, it should be a massive neon sign that there needs to be some moderation functionality.
Because there isn’t a solution.
This has been discussed and experimented with to death where such networks existed for a long time. Just because you never heard of them or even knew they exist doesn’t mean that they don’t.
See Freenet/Hyphanet and the three approaches (local trust, shared user trust lists, web of trust) if you want to learn something. The second one worked out the best from a performance and scalability point of view compared to the third.
Holy shit you cannot be serious. In the shortest possible terms: trust systems are forms of moderation. Anything implementing them would not fall under what I was talking about.
This project doesn’t appear to implement that. It doesn’t even appear to have a bare minimum way for users to prevent themselves from sharing something they viewed but don’t want to share. Viewing something should not imply trust.
Definitely appreciate the assumption that I’m just a dumbass and you’ve come to shine the light of enlightenment on me though. That my point of view could only be possible to reach through ignorance. That’s always nice.
Apologies if I was presumptions and/or my tone was too aggressive.
Quibbling at No Moderation = Bad usually refers to central moderation where “someone” decides for others what they can and can’t see without them having any say in the matter.
Bad moderation is an experienced problem at a much larger scale. It in fact was one of the reasons why this very place even exists. And it was one of the reasons why “transparent moderation” was one of the celebrated features of Lemmy with its public
Modlog, although “some” quickly started to dislike that and try to work around it, because power corrupts, and the modern power seeker knows how to moral grandstand while power grabbing.All trust systems give the user the power, by either letting him/her be the sole moderator, or by letting him/her choose moderators (other users) and how much each one of them is trusted and how much weight their judgment carries, or by letting him/her configure more elaborate systems like WoT the way he/she likes.
Can you host a node to earn its token?
If there’s no central server then where is all the data stored?. With Lemmy I know the instance creator has to host it all on his own server.
Great question! Unlike Lemmy, which relies on federation with dedicated servers, Plebbit is fully peer-to-peer (P2P) and does not have a central server or even instances. Instead, storage happens via a combination of IPFS and users seeding data. Here’s how it works:
Where Is Plebbit’s Data Stored?
-
Subplebbit Owners Host the Data (Like Torrent Seeders)
- Each subplebbit owner runs a Plebbit node that stores and republishes their own community’s data.
- Their device (or a server, if they choose) must be online 24/7 to ensure the subplebbit remains accessible.
- If a subplebbit owner goes offline, their community disappears unless others seed it—very similar to how torrents work.
-
Users Act as Temporary Seeders
- Any user who visits a subplebbit automatically stores and seeds the content they read.
- This means active users help distribute content, like in BitTorrent.
- If a user closes their app and no one else is seeding the content, it becomes unavailable until the owner comes back online.
-
IPFS for Content Addressing
- Posts and comments are stored in IPFS, which ensures that popular content remains available longer.
- Unlike a blockchain, there is no permanent historical ledger—if no one is seeding, the data is gone.
- Each post has a content address (CID), meaning that as long as someone has the data, it can be re-fetched.
-
PubSub for Live Updates
- Plebbit uses peer-to-peer pubsub (publish-subscribe messaging) to broadcast new content between nodes in real-time.
- This helps users see new posts without needing a central server to pull updates from.
What Happens If Everyone Goes Offline?
- If no one’s online to seed a subplebbit, it’s as if it never existed.
- This is a trade-off for infinite scalability—it removes the need for central databases but relies on community participation.
- Think of it like a dead torrent—no seeders, no content.
Comparison With Lemmy
Feature Lemmy Plebbit Hosting Model Federated servers (instances) Fully P2P (no servers) Who Stores Data? Instance owners (like Reddit mods running a server) Subplebbit owners & users (like torrents) If Owner Goes Offline? Instance still exists; data stays up The community disappears unless users seed it Historical Content Availability Instances keep all posts forever Older data may disappear if not seeded Scalability Limited by instance storage & bandwidth Infinite, as long as people seed
Bottom Line: No Servers, Just Users
- With Lemmy: The instance owner has to host everything themselves like a mini-Reddit admin.
- With Plebbit: The subplebbit owner AND users seed the content—no one has to host a centralized database.
- If something is popular, it stays alive.
- If something isn’t seeded, it disappears, just like torrents.
It’s a radical trade-off for decentralization and censorship resistance, but if no one cares about a community, the content naturally dies off. No server, no mods deleting you from a database—just pure P2P.
Hope that clears it up! 🚀
Is this reply AI generated?
How are users able to decide what they seed and what they don’t? Just because I viewed something doesn’t mean I necessarily want to support its proliferation.
Either way you still do. Think about it.
Please spare me whatever philosophical navel gazing you’re trying to do here. I’m asking what should be an incredibly straightforward question about what should be basic functionality in any P2P seeding based system:
What control, if any, does an individual user have over what they seed back into the system?
Some P2P systems just give each user an encrypted blob of all sorts of stuff, so the individual user can’t choose and on paper isn’t responsible for whatever it is that they are seeding back in. I’m personally not ok with not having a way to ensure that I’m not seeding nazi manifestos that were stealthing as a reasonably named subplebbit.
I liked “navel gazing” I’m keeping that one.
I will still check it out, but it doesn’t mean I will adopt it.
Fair
I’m personally not ok with not having a way to ensure that I’m not seeding nazi manifestos that were stealthing as a reasonably named subplebbit.
I kind of get the feeling this is exactly the content they want to help host when they refer to “censorship resistance”. This was also the key selling point of Gab when it launched.
Edit: even their logo is a meme commonly used in far right circles, so there seem to be a lot of dog whistles for the type of community they want to create.
Not only is IPFS not built on solid foundations, offered nothing new to the table, and is generally bad at data retention, but the “opt-in seeding” model was always a step backwards and not a good match for apps like plebbit.
The anonymous distributes filesystem model (a la Freenet/Hyphanet) where each file segment is anonymously and randomly “inserted” into the distributed filesystem is the way to go. This fixes the “seeder power” problem, as undesirable but popular content can stay highly available automatically, and unpopular but desirable content can be re-inserted/healed periodically by healers (seeders). Only both unpopular and undesirable content may fizzle out of the network, but that can only happen in the context of messaging apps/platforms if 0 people tried pull and 0 people tried to reinsert the content in question over a long period of time.
When everyone will have a 50G PON fiber connection at home, IPFS is going to be the standard serverless configuration.
2030? Everyone uses that date for everything futuristic
Thanks for the detailed reply that helps, this sounds really interesting, with the late stage capitalism we are going through, I’ve lost all interest in private corporate controled social networks, hence the switch to Lemmy, but the instance owner is still a single point of failure with Lemmy but at least you can switch to another instance.
I have a few concerns about Plebbit though.
A - with torrents you know the size of the torrent beforehand and can decide if you can download it all and continue seeding it so long as you have the space for it on your drive, but with a forum like Plebbit, how would a user know how much space on their drive Plebbit will take for the Plebbit content they interact with. Is there a way to dedicate X gigabytes of limited storage space for it and anything above that gets purged to make space for new data?
B - One of the best uses Of Reddit imo is that it’s very easy to Google for something and find a relevant Reddit thread, especially for something niche, since Plebbit only keeps the most popular content and the rest goes away if not seeded, does it mean it won’t be a good for niche archival data, maybe that’s a use case that Plebbit isn’t design to handle and that’s okay.
C - Bots are a big concern for most social media, especially the ones used for spreading propaganda and misinformation, how does a P2P social forum like Plebbit plan to handle bots.?
So there are servers then…
