# LBRYnet
|
|
|
|
LBRYnet is a fully decentralized network for distributing data. It consists of peers uploading
|
|
and downloading data from other peers, possibly in exchange for payments, and a distributed hash
|
|
table, used by peers to discover other peers.
|
|
|
|
## Installation
|
|
|
|
Download the [latest release](https://github.com/lbryio/lbry/releases/latest) or see [INSTALL.md](INSTALL.md) for manual installation.
|
|
|
|
## Overview
|
|
|
|
On LBRYnet, data is broken into chunks, and each chunk is specified by its sha384 hash sum. This
|
|
guarantees that peers can verify the correctness of each chunk without having to know anything
|
|
about its contents, and can confidently re-transmit the chunk to other peers. Peers wishing to
|
|
transmit chunks to other peers announce to the distributed hash table that they are associated
|
|
with the sha384 hash sum in question. When a peer wants to download that chunk from the network,
|
|
it asks the distributed hash table which peers are associated with that sha384 hash sum. The
|
|
distributed hash table can also be used more generally. It simply stores IP addresses and
|
|
ports which are associated with 384-bit numbers, and can be used by any type of application to
|
|
help peers find each other. For example, an application for which clients don't know all of the
|
|
necessary chunks may use some identifier, chosen by the application, to find clients which do
|
|
know all of the necessary chunks.
|
|
|
|
## For Developers
|
|
|
|
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:
|
|
|
|
```
|
|
from jsonrpc.proxy import JSONRPCProxy
|
|
|
|
try:
|
|
from lbrynet.conf import API_CONNECTION_STRING
|
|
except:
|
|
print "You don't have lbrynet installed!"
|
|
API_CONNECTION_STRING = "http://localhost:5279/lbryapi"
|
|
|
|
api = JSONRPCProxy.from_url(API_CONNECTION_STRING)
|
|
if not api.is_running():
|
|
print api.daemon_status()
|
|
else:
|
|
for func in api.help():
|
|
print "%s:\n%s" % (func, api.help({'function': func}))
|
|
```
|
|
|
|
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'.
