ed25519
Signed events
Every event is canonical JSON, hashed with SHA-256 and signed with Ed25519. Identity is a keypair — no accounts, no sessions, no passwords.

Stop trusting corporations. Build your own apps. Encrypt everything. Push once — access it everywhere. Every demo below is signed in your browser and served by a live Rabta node — no accounts, no database server, no cloud.
Capabilities
six core pillars · wire-level specsquery
Live queries
Poll any collection through a typed JSON query. Filter by labels or owner, and page results with an opaque cursor.
Cursor paging
10 labels
HTTP poll
sha-256
Content-addressed blobs
Uploads return their SHA-256, dedupe automatically and expire with the signed events that claim them. Encrypt client-side and the relay only sees ciphertext.

Yours to run
One Rust binary, one SQLite file, one container. No database server, no cloud dependency, no per-user pricing — deploy it anywhere.

Autonomous peer sync
Decentralized multi-node replication. Nodes reconcile diverged event sets in milliseconds using a 256-bucket XOR folding Merkle walk without central coordinators.

ring · sandbox
Machine anti-spam
Engineered to protect the host machine: a 64k-entry in-memory ring buffer drops spam in microseconds, backed by battery token accounting and isolated staging.

Guarantee
Relay verifies Ed25519 signature over canonical SHA-256 digest. Server never holds private keys.
Demos
four demos · one relay
01
Canvas
Realtime 1000×1000 board. Strokes are signed in your browser, then polled by every viewer.
canvas/rabta
02
Share
Up to 8 files and a note, encrypted in the browser. The key lives in the link fragment — the relay never sees it.
share/rabta
03
World
A world map where anyone can pin a signed comment to exact coordinates. Every note appears live.
world/comments
04
Shoutbox
A public board where every message is signed in your browser and polled live by everyone else on the page.
