Privacy & K-Anonymity

Blind Relay Architecture

Push notifications use a "Blind Relay" — the server that wakes your device cannot determine recipients. It only sees anonymous tags with no link to identities or channels.

K-Anonymity (Adaptive)

Notification tags use a deliberately small hash (1 byte = 256 possible values) to ensure K-anonymity even with few users. With 1,000 users, each tag matches ~4 people. As the user base grows, the tag size scales up. You're always hidden in a crowd.

What the Relay Sees

Cannot see: Who receives the notification (k-anonymity)
Cannot see: Which channel the message is from
Cannot see: Message content (separate stream, never touches relay)
Can see: Sender's Streamr node address (inherent to network)

Anti-Spam Protection

Each wake signal requires Proof-of-Work (~200ms per recipient). Negligible for normal use, but makes spam prohibitive — a spammer would need hours of computation to flood the network.

The relay is fully open-source. Anyone can run their own instance for additional trust guarantees.
