we use IPNS for mutable data (like upvote counts, reply counts, etc) https://specs.ipfs.tech/ipns/ipns-record/ and gossipsub for an author node to communicate their publication to a community node https://docs.libp2p.io/concepts/pubsub/overview/
Plebbit differs from Nostr in that Nostr is federated (using instances), whereas Plebbit is P2P (fully decentralized). Plebbit uses IPFS, which is more similar to BitTorrent, which is pure P2P as well.
The issue with federations is that their instances are not easy to set up, most users don’t have an incentive to do so, and even if they did, they are not censorship resistant at all, because they work like regularly centralized websites. Your Nostr/Lemmy/Mastodon instance can get DDOS’d, deplatformed by the SSL certificate provider, deplatformed by the datacenter, deplatformed by the domain name registrar. The instance admin can get personally doxxed and harassed, they can get personally sued for hosting something a user posted, etc. And instances can block each other.
Whereas running a node on Plebbit is as easy as opening up one of its desktop clients, which automatically run the custom IPFS node in the background, and seed all the protocol data automatically (similarly to how a BitTorrent client seeds torrents). It runs on a raspberry pi, on 4GB of RAM and consumer internet. It scales like torrents, i.e. the more users connect p2p, the faster the network gets. And most importantly, nobody can stop you or block you from connecting to another user, because there’s nobody in between. This means nobody can stop you from connecting to a subplebbit (subreddit clone). If you run your own community, you’re always reachable by any user on plebbit.
Steemit is A, it’s a regularly centralized website with global admins, claiming to be “decentralized” simply because it’s built on a blockchain. Whenever you are asking yourself whether something is “decentralized” or not, ask “how can I run a full node”? “What are the hardware requirements”? Steemit admins won’t answer those questions. Whereas you can easily spin up your own ActivityPub (Mastodon or Lemmy) instance (even though those instances work like regularly centralized websites, at least you have the option to run your own).
On Plebbit, just using the desktop app of a client (like Seedit’s desktop app you can download here means you are running a full node already. The app runs an IPFS node in the background, seeding all content you browse automatically, thereby improving the speed of the network for everybody else. The more nodes there are, the more decentralized the network is, so if all users can easily run a node and are incentivized to do so, then the network is properly decentralized/distributed. On Seedit, you can’t run a community if you don’t run a full node (the community is the node, acting like a server, and users connect to it P2P). There are no global admins.
Yes. Reddit is A, ActivityPub (Lemmy, Mastodon) is B, Plebbit (Seedit, Plebchan) is C:
https://seedit.app is a fully decentralized client for the Plebbit protocol, using a old.reddit UI.
You can also try a demo of a much faster version of Seedit, it works via public RPC: https://plebbit.mooo.com/seedit/#/hot (warning: you’re using someone else’s full node to browse fully P2P, so if you create a community it’s in their node, it’s not yours). This version showcases how you can create a community even on mobile device, running a full node remotely. But we have to build user auth for this, it’s in our roadmap.
It doesn’t need crypto, it only needs IPFS (but we could change underlying protocol in the future, if someone creates a better alternative to IPFS).
“no transaction fees” is listed as a feature because blockchain-based social media exists, and unlike them a plebbit full node doesn’t have to sync (because it’s a IPFS node), it just runs immediately like a BitTorrent node would, and it runs on 4GB of RAM even on a raspberry pi, on consumer internet (consumes less bandwidth than YouTube) and it only uses a few GBs of storage. Blockchain social media fundamentally cannot scale because of node requirements, that is if you want the platform to be “decentralized” (enough full nodes).
We do have crypto features, as an addendum. Mainly, we use crypto domains such as .eth (ens.domains) end .sol (sns.id) to resolve plebbit author/community addresses to readable names, because they are IPNS public keys (very long and impossible to memorize, e.g. 12D3KooWMLCgrZT8Ucaw2DWnv1HsQianf9tVi8sK6JCbCod3XK8T). Unlike DNS, crypto domains are censorship resistant. They are cryptographic property, you hold them in your wallet, which means if you change the address of your plebbit community to one such domain, you are tokenizing your community. In theory, the more users your community has, the more people have saved your domain, the higher its value. Compare that to Reddit for example, where all subreddits are owned by Reddit, they can ban your community with millions of subs, because it’s not your property, it’s theirs.
plebbit.com is just a landing page made by a member of the community, to explain the project. To use plebbit, you can check out its clients, like Seedit.
Links have a character count limit, you can’t link to a base64 image on plebbit.
It’s not a competing standard, it’s a whole new approach to decentralize forum-based social media.
ActivityPub is not fully decentralized, it’s a federated design, meaning it’s a network of instances, and each instance is just a regular website with servers. Anyone can run an instance, but it’s expensive, tiresome and you’ll get banned for it; they are regular websites.
whereas Plebbit is fully decentralized, it’s purely peer to peer, meaning it’s a network of peers where every peer can potentially be a full node by simply using the desktop app (or in the future, a non custodial public rpc on mobile), and you don’t have to run any site/domain for it, it’s censorship resistant just like running a torrent with a BitTorrent client.
Also to be clear: like ActivityPub is a protocol with clients, such as Mastodon and Lemmy, Plebbit is a protocol with clients, such as Seedit and Plebchan.
Because this way it has no central server, database, HTTP endpoint or DNS - it is pure peer to peer. Unlike federated instances, which are regular websites that can get deplatformed at any time, plebbit full nodes are customized IPFS Kubo nodes, and running one is as simple as downloading the Seedit client desktop app (available on github) and keeping it open. It runs the node automatically, and seeds content automatically as you browse it. It runs on a raspberry pi, so we expect to see a lot of plebbit users running their own full node.
