Decentralized websites using Bitcoin crypto and the BitTorrent network - https://zeronet.io / onion


  • We believe in open, free, and uncensored network and communication.
  • No single point of failure: Site remains online so long as at least 1 peer is serving it.
  • No hosting costs: Sites are served by visitors.
  • Impossible to shut down: It's nowhere because it's everywhere.
  • Fast and works offline: You can access the site even if Internet is unavailable.


  • Real-time updated sites
  • Namecoin .bit domains support
  • Easy to setup: unpack & run
  • Clone websites in one click
  • Password-less BIP32 based authorization: Your account is protected by the same cryptography as your Bitcoin wallet
  • Built-in SQL server with P2P data synchronization: Allows easier site development and faster page load times
  • Anonymity: Full Tor network support with .onion hidden services instead of IPv4 addresses
  • TLS encrypted connections
  • Automatic uPnP port opening
  • Plugin for multiuser (openproxy) support
  • Works with any browser/OS

How does it work?

  • After starting zeronet.py you will be able to visit zeronet sites using{zeronet_address} (eg.
  • When you visit a new zeronet site, it tries to find peers using the BitTorrent network so it can download the site files (html, css, js...) from them.
  • Each visited site is also served by you.
  • Every site contains a content.json file which holds all other files in a sha512 hash and a signature generated using the site's private key.
  • If the site owner (who has the private key for the site address) modifies the site, then he/she signs the new content.json and publishes it to the peers. Afterwards, the peers verify the content.json integrity (using the signature), they download the modified files and publish the new content to other peers.
