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.

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.

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.
