How to participate

If you like to get a better overview of the challengers, join the kickoff live stream. You may also join later on.

Most projects listed their challenges as sprint issues on Github, simply comment on those that you are interested in and the project mentors should get back to you.

Also register on https:/ and let us know in the channel "Lightning HackSprint" what you like to work on.

Find routes that satisfy additional criteria, for instance, must [not] go through certain nodes. More info and discussion here:

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:

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

Adding your Project

Feel free to add a challenge yourself! The wiki is open to any Bolter (you'll figure out how to edit.) Get in touch on Mattermost for more information and collaboration.
