===Rust Lightning network node===
 
 
Another LN node? Why we need it?
 
 
The problem with the existing Lightning node implementations is their very limited extensibility for such things as:
 
 
* future LN upgrades (channel factories, pay-to-ec-point, taproot),
 
* protocols on top of LN (layer 3), like [https://hackmd.io/@lpQxZaCeTG6OJZI3awxQPQ/LN-DLC DLCs on LN] or proposed [https://github.com/LNP-BP/lnpbps/issues/24 Lightspeed payments], which require modification on the structure of the commitment transaction.
 
 
We will try to build a node that is highly modular and is ready for the future LN extensions. More information here: https://github.com/LNP-BP/lnpd
 
 
During the hackathon we will try to:
 
* compose core architecture with non-blocking multithreading
 
* add lightning network wire protocol
 
* implement BOLT-9 (using rust-lightning it should be simple)
 
* implement BOLT-1: do connection to other LN nodes + send/receive `connect`, `ping` & `ping` messages
 
* (optionally) implement gossip protocol

===Backup plugin for c-lightning===
 
 
Backups are a major issue in the Lightning Protocol, given that any sort of
 
dataloss could potentially result in loss of funds. This means that restoring
 
an old backup of the database could result in the node broadcasting an old
 
state, which is a cheat attempt in the protocol, which is punished.
 
 
The backup c-lightning plugin (https://github.com/lightningd/plugins/pull/97)
 
implements the basic mechanisms to create a synchronous backup of
 
any change to the database, and ensures that the backup stays in sync with the
 
database. It does so in a generic way allowing to write backups to a variety
 
of backends, but initially only implements a file-system based backup backend
 
that is located on the same machine, but on a separate disk. Doing so already
 
provides protection against data corruption on the primary disk. Potential
 
future improvements could include:
 
 
* Backup to Google services. Examples include:
 
** GDrive
 
** Google Docs - Sheets
 
** Google Cloud Storage
 
* Backup to Dropbox
 
* Send backup data to a peer using the custommsg hook
 
* Backups to a dedicated backup server
 
 
In the case of a dedicated backup server the plugin could also manage a
 
subscription that is used to pay for the backup service.

===Low Bandwidth Lightning Channels===
 
 
There is a need to strengthen the Bitcoin ecosystem for people whose only computing device is a low end mobile phone and who live where Internet access is expensive, unreliable, intermittent or censored. [https://github.com/willcl-ark willcl-ark] created a way to proxy Lightning channels over low-bandwidth communication systems using a c-lightning patch "[https://github.com/willcl-ark/lnproxy/blob/master/clightning/noencrypt_final.patch noencrypt]" and python plugin called [https://github.com/willcl-ark/lnproxy lnproxy]. This plugin is written specifically to use a goTenna radio connected to a computer over USB, but this system can also be adapted for other low-bandwidth channels like SMS (for people who cannot afford mobile internet), LoRa mesh radio or similar systems. [https://github.com/jharveyb jharveyb] is working on [https://github.com/jharveyb/fldigi-proxy fldigi-proxy] to help adapt LNProxy for ham radio and willcl-ark has created a [https://github.com/willcl-ark/lnproxy/commits/2020-02-23-ham fork of lnproxy that uses sockets] to work with the fldigi-proxy.
 
 
You can read more about LNProxy [https://inthemesh.com/archive/lntenna-python-3/ here] to get an overview of the project.
 
 
The challenge is to adapt LNProxy to a different low-bandwidth communication method. For example, LoRa radio, Bluetooth or an SMS API.
