# ZeroNet [](https://travis-ci.org/HelloZeroNet/ZeroNet) [](https://zeronet.io/docs/faq/) [](https://zeronet.io/docs/help_zeronet/donate/)  [](https://hub.docker.com/r/nofish/zeronet)
Decentralized websites using Bitcoin crypto and the BitTorrent network - https://zeronet.io
## 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 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.
## Features
* Real-time updated sites
* Namecoin .bit domains support
* Easy to setup: unpack & run
* Clone websites in one click
* Password-less [BIP32](https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki)
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
`http://127.0.0.1:43110/{zeronet_address}` (eg.
`http://127.0.0.1:43110/1HeLLoPVbqF3UEj8aWXErwTxrwkyjwGtZN`).
* 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.

## Current limitations
* ~~No torrent-like file splitting for big file support~~ (big file support added)
* ~~No more anonymous than Bittorrent~~ (built-in full Tor support added)
* File transactions are not compressed ~~or encrypted yet~~ (TLS encryption added)
* No private sites
## How can I create a ZeroNet site?
* Click on **⋮** > **"Create new, empty site"** menu item on the site [ZeroHello](http://127.0.0.1:43110/1HeLLoPVbqF3UEj8aWXErwTxrwkyjwGtZN).
* You will be **redirected** to a completely new site that is only modifiable by you!
* You can find and modify your site's content in **data/[yoursiteaddress]** directory
* After the modifications open your site, drag the topright "0" button to left, then press **sign** and **publish** buttons on the bottom
