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 DLCs on LN or proposed 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:
- 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. willcl-ark created a way to proxy Lightning channels over low-bandwidth communication systems using a c-lightning patch "noencrypt" and python plugin called 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. jharveyb is working on fldigi-proxy to help adapt LNProxy for ham radio and willcl-ark has created a fork of lnproxy that uses sockets to work with the fldigi-proxy.
You can read more about LNProxy 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.

Adding your Project
Feel free to add a challenge yourself! The wiki is open to any Bolter (you'll figure out how to edit). If you have a GitHub Repo best practice is to put the label "hackathon" (yellow) next to issues you like people to join/help for the weekend. If you added a challenge please also get in touch on Mattermost for more information and collaboration.
