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

c-lightning

User:Cdecker is available on Mattermost for mentoring of c-lightning projects. Feel free to propose your own ideas, and we'll help you design and implement them :-)

Some ideas for projects / challenges: 

- Hardware wallet integration: c-lightning has supported external funding via the `fundchannel_start` and `fundchannel_complete` RPC methods for quite some time, in addition the `close_to` parameter allows you to specify where funds should be sent once the channel closes. These can be combined to have all on-chain funds sourced from a hardware wallet and, after they were borrowed to operate a channel, they can be returned to the hardware wallet. The idea here is to write a plugin that interacts with the hardware wallet to fund channels, so funds are only temporarily controlled by c-lightning.

- `hsm_secret` generation from a seed-phrase: c-lightning will securely generate a random seed when first starting a new node. Given the lack of functional backup, and the seed not being sufficient to restore all the state, c-lightning has so not included any seed-phrase to restore the seed. However due to recent improvements both in backups and replicated DB backends, it would be great to also safely store the `hsm_secret` using existing tooling, such as paper backups, encrypted BIP39 seed-phrases, or even steel backups. Goal of this challenge is the creation of a launcher or plugin that takes a seed-phrase and generates the associated `hsm_secret` file.

Adding your Project

Feel free to add a challenge yourself! Ask Jeff or Rootzoll on the Mattermost for the password to edit the Wiki-Page. 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.
