ZeroNet

ZeroNet

Decentralized websites using Bitcoin crypto and the BitTorrent network

Why?

• 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 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 your internet is unavailable.

Features

• Real-time updated sites
• Namecoin .bit domains support
• Easy to setup: unpack & run
• Password-less BIP32 based authorization: Your account is protected by same cryptography as your Bitcoin wallet
• Built-in SQL server with P2P data synchronization: Allows easier site development and faster page load times
• Tor network support
• 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 http://127.0.0.1:43110/{zeronet_address} (eg. http://127.0.0.1:43110/1EU1tbG9oC1A8jz2ouVwGZyQ5asrNsE4Vr).
• 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 becomes also served by you.
• Every site contains a site.json which holds all other files in a sha512 hash and a signature generated using 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. After the peers have verified the content.json integrity (using the signature), they download the modified files and publish the new content to other peers.
