# LBRY # LBRY
LBRY is a fully decentralized, open-source protocol facilitating the discovery, access, and (sometimes) purchase of data. LBRY is a fully decentralized, open-source protocol facilitating the
discovery, access, and (sometimes) purchase of data.
## Installing LBRY This repo is a reference implementation of the LBRY protocol and
provides daemon that can interact with the network via a json-rpc
interface.
We provide binaries for Windows, macOS, and Debian-based Linux. ## Installing the LBRY App
The LBRY App is a decentralized content marketplace built on top of
the LBRY protocol. We provide binaries for Windows, macOS, and
Debian-based Linux.

## Using the LBRY daemon
See our quickstart guide at http://lbry.io/quickstart for details on how to install and use the `lbrynet-daemon`.

## For Developers ## Contributions
The bundled LBRY application uses the lbrynet JSONRPC api found in `lbrynet.lbrynet_daemon.LBRYDaemon`. This api allows for applications and web services like the lbry browser UI to interact with lbrynet. If you've installed lbrynet, you can run `lbrynet-daemon` without running the app. While the app or `lbrynet-daemon` is running, you can use the following to show the help for all the available commands:
```
import sys
try:
from lbrynet import conf
from lbrynet.lbrynet_daemon.auth.client import LBRYAPIClient
except ImportError:
print "You don't have lbrynet installed!"
sys.exit(0)
conf.initialize_settings()
api = LBRYAPIClient.get_client()
try:
status = api.status()
except:
print "lbrynet-daemon isn't running!"
sys.exit(0)
if not status['is_running']:
print "lbrynet-daemon hasn't finished starting up, here's the status message:"
print status
sys.exit(0)
else:
for cmd in api.commands():
print "%s:\n%s" % (cmd, api.help({'command': cmd}))
```
If you've installed lbrynet, it comes with a file sharing application, called `lbrynet-daemon`, which breaks
files into chunks, encrypts them with a symmetric key, computes their sha384 hash sum, generates
a special file called a 'stream descriptor' containing the hash sums and some other file metadata,
and makes the chunks available for download by other peers. A peer wishing to download the file
must first obtain the 'stream descriptor' and then may open it with his `lbrynet-daemon` client,
download all of the chunks by locating peers with the chunks via the DHT, and then combine the
chunks into the original file, according to the metadata included in the 'stream descriptor'.
