Challenges May 2020
How to participate
If you like to get a better overview of the challenges, join the kickoff livestream. You may also join later on.
Most projects listed their challenges as sprint issues on Github with the lable "hackathon". Simply comment on those that you are interested in and the project mentors should get back to you.
To participate please register on our Mattermost (OpenSource Slack) and check if there is already a chat room regarding the project you are interested. In the channel "Lightning HackSprint" should always be someone around to point you into the right direction if you have any further questions.

getroutevia: a c-lightning plugin for route search with restrictions
Find routes that satisfy additional criteria, for instance, must [not] go through certain nodes. More info and discussion here: https://github.com/s-tikhomirov/getroutevia/issues/1
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

Weenode
This is the new name for the cheapnode project. Help wanted on Github issues with label "hacksprint"
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.

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.
