====== Multiverse (Federation system) =====

===== Introduction =====

[[:socialnet/overview|OASIS]] contains its own Multiverse module (formerly //Fediverse//), a bridge that lets you **connect and manage your accounts on other social networks** directly from inside the network.

The main idea behind this implementation is **to send and receive content across other networks without locking you into a single platform** and __without storing any third-party data in your append-only log__. Your timelines and chats are fetched live and rendered on the fly, so OASIS stays light while you stay connected to the outside world.

===== How it works =====

- **Nothing third-party is stored**: Remote posts, chats and messages are requested live for each visit and shown ephemerally. They are **never** written into your `.ssb` feed, so your log is not filled with other people's content.

- **Local credentials only**: Your access token (Mastodon) or your API hash and session (Telegram) are kept in a local, private configuration file readable only by your user. They are **never** published to the network, never committed to any repository, and never shown back in the interface.

- **Clean disconnect**: Disconnecting a network wipes its credentials from disk. For Telegram, OASIS also logs the session out on Telegram's side, so a leaked copy of the file would be useless.

- **Privacy by default**: Every outbound HTTP request uses the **same uniform browser headers** for all OASIS users, so no per-user metadata leaks and the origin is protected. Telegram is reached directly over MTProto from your node, exactly like a regular client.

- **Proxied media**: Remote avatars, images, videos and files are fetched through the OASIS backend with anti-SSRF protection (Mastodon) or downloaded on demand from Telegram and served locally, never linking your browser to third-party hosts. Remote HTML is always sanitized before display.

===== Connecting your accounts =====

- **Mastodon**: read your home timeline, publish (text, images and video), reply, boost and favourite.

- **Telegram**: read your chats, groups and channels, open any conversation and send messages or files.

===== Purpose =====

The Multiverse module of [[:socialnet/overview|OASIS]] is not merely a Mastodon or Telegram client — **it is a statement about how federation should feel from a libre, privacy-first network**.

By letting you reach other networks __without surrendering your data, your metadata or your attention__, it treats them as peers rather than silos. Remote content stays ephemeral, your identity stays yours, and your origin stays hidden — yet you can still participate fully in the global conversation.

Ultimately, its purpose is to connect OASIS to the rest of the world **on the community's own terms** — sending and receiving content freely, while keeping the network light, private and humane as it grows.
