# 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.


## 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.

### Linux

#### Debian

#### Other Linux or without root access
* Check your python version using `python --version` if the returned version is not `Python 2.7.X` then try `python2` or `python2.7` command and use it from now
* `wget https://bootstrap.pypa.io/get-pip.py` 
* `python get-pip.py --user pyzmq gevent msgpack-python`
* Start with `python zeronet.py`

## Current limitations

* No torrent-like, file splitting for big file support
* No more anonymous than Bittorrent
* File transactions are not compressed or encrypted yet
* No private sites
* You must have an open port to publish new changes
* Timeout problems on slow connections


## How can I create a ZeroNet site?

Shut down zeronet if you are running it already

```bash
$ zeronet.py siteCreate
...
- Site private key: 23DKQpzxhbVBrAtvLEc2uvk7DZweh4qL3fn3jpM3LgHDczMK2TtYUq
- Site address: 13DNDkMUExRf9Xa9ogwPKqp7zyHFEqbhC2
...
- Site created!
$ zeronet.py
...
```

Congratulations, you're finished! Now anyone can access your site using
`http://localhost:43110/13DNDkMUExRf9Xa9ogwPKqp7zyHFEqbhC2`
