WIFI Mesh Networks

  • A few cities have them
  • IP networks -> Internet
  • Stationary Access points (wifi)
  • Expensive Backhaul Mesh (5.8ghz)
  • Lots of maintenance
  • Lots of routing protocols, hardware, legacy software, fcc, local store owners , angry neighbors, why are you on my roof?, is that a IED? I'm calling the cops!

The Dream

Decentralized behaviors
served by decentralized apps
over decentralized networks.

10 / 22

Behaviors

  • Chatting (irc, gtalk, twitter, WhatsApp)
  • Long Form Messages (email, blogs)
  • Media Sharing (photos, music, video)
  • Local Human Discovery (Bars, Tinder, Foursquare)
11 / 22

Apps

  • Bitcoin, Namecoin, Zeocoin - All use irc =(
  • Bittorrent with DHT (local peer discovery, local peer priority)
  • Gnutella/Kazza (connect to anybody, each node is the same)
  • Darknets (tor, i2p, freenet, WASTE)
  • Bittorrent chat (announced)
12 / 22

Networks

  • Internet (primarily centralized)
  • Cell (centralized)
  • Bluetooth/BLE (centralized and tiny)
  • Lan (centralized, but privately owned)
  • NFC (decentralized but very low range)
  • GoTenna (not announced, BLE+phone?)
  • XBEE (centralized but not for long)

XBEE

  • Supports Ad Hoc Mesh Network
  • Currently centralized but firmware is coming to remove this from lightbulb manufactures (seriously)
  • smart cheap little chips
  • <$50 for device and usb
  • Speaks Serial (node-serialport)

Hacker Chat

  • WhatsApp for Hackers (I've never used WhatsApp)
  • Use XBEE as a proof of concept network
  • Use Node to power it
  • Peer Discovery
  • Peer to Peer Chat
  • Broadcast Chat
19 / 22

Demo

https://github.com/reconbot/hackerchat
npm install -g hackerchat

Wish: Hacker Email

  • Email that is very delay tolerant (sends when you're in range of other people)
  • Namecoin is a distributed cryptographically secure hash table, could be used for username registration, a "first contact" cost, and public and private key communication
  • A truly ad hoc decentralized network hardware
