Pubky: 30-Second Overview

Pubky is a decentralized web protocol that puts you in control of your identity and data.

What It Is

  • Your Identity = Your Key: No usernames, no accounts. Your public key is your permanent identity.
  • Your Data, Your Choice: Store data on any homeserver you choose. Switch anytime without losing anything.
  • Censorship Resistant: Built on the Mainline DHT (15+ years proven, 10M+ nodes). No single authority can block you.
  • No Blockchain: Fast, free operations using standard web technologies (HTTP/HTTPS).

How It Works

flowchart LR
    You[Your Key] --> PKARR[PKARR Record]
    PKARR --> DHT[Mainline DHT]
    PKARR --> HS[Your Homeserver]
    Apps[Apps] --> HS
    Apps --> DHT
  1. Generate a cryptographic key pair (your identity)
  2. Publish a PKARR record to the DHT (points to your homeserver)
  3. Store your data on any homeserver
  4. Apps discover and access your data via your public key

Why It Matters

Replace Big Tech: No algorithm controls your feed. No company owns your data.

Replace Big State: Censorship becomes impractical when data lives on millions of distributed nodes.

Replace Big Banks: Native integration with Bitcoin/Lightning for true financial freedom (coming soon).
