Overview

Send data to other nodes in the Lightning Network.

This project mainly serves as a demonstration to the DataSig and DataStruct specs that are about to be proposed to the BLIP repo of Lightning.

Usage

The receiving node must have --accept-keysend enabled in order to accept the spontaneous payments carrying data.

Rename config.sample.yaml to config.yaml and fill in the URL, macaroon path and TLS path for your LND.

Configure the tlv_key for data_sig and data_struct, this needs to be a uint64 number that is odd and greater than 65536.

Note that receiver must also run this application and have the same keys configured in order to normally receive data.

Run npm start.

Commands

  • set <address>: Sets the destination address to transmit data to
  • speak <string>: Sends the given text to the destination.
  • send <filepath>: Sends the contents of the file at given path.

    Why not using onion messages?

    Just curious I think Onion Messages can be used to partially achieve this. Wouldn't it make more sense to build on top of them? c.f: https://github.com/lightning/bolts/pull/759

  • Reliable fragment transmission

    Reliable fragment transmission

    • Fix semantics in config.yaml related to fragment sizes. Now only 1 value is configured and that's the static size of all fragments.
    • Changes fragment transmission operation, now fragments are send in sync. Previously the async burst of requests caused LND to stall.

App that receives data from a microcontroller that is set up at your electricity meter, which at certain intervals will send an image to be processed, this then gets sent to a Python instance which will get the data read from the image. That data gets sent back and will be saved to the account this meter belongs to. This gives you the ability to track your currently analog meter in a digtal environment.
