eclair
A scala implementation of the Lightning Network. Eclair is french for Lightning.
More precisely, this is an implementation of Rusty's deployable lightning. In particular it uses the same wire protocol, and almost the same state machine.
Overview
The general idea is to have an actor per channel, everything being non-blocking.
A "blockchain watcher" is responsible for monitoring the blockchain, and sending events (eg. when the anchor is spent).
Modules
- lightning-types: scala code generation using protobuf's compiler (wire protocol)
- eclair-demo: actual implementation
Usage
Run Demo.scala
to have an example of:
- Opening a channel
- Updating the balance with an HTLC
- Closing the channel
Status
- Network
- Routing
- Channel state machine
- HTLC Scripts
- Unilateral close handling
- Relaying Payment
- Blockchain watcher
- Storing states in a database
