lnrpc: add the devrpc development only subserver + devrpc.ImportGraph
This commits adds the devrpc package which implements a subserver that
adds clean separation for RPC calls useful for development and
debugging. This subserver is only compiled in if the dev tag is set.
Furthermore the commit adds the devrpc.ImportGraph call which can
import a graph dump obtained from another node by calling DescribeGraph.
Since the graph dump does not include the auth proofs, the imported
channels will be considered private.

Lightning Network Daemon

Build Status MIT licensed Irc Godoc

The Lightning Network Daemon (lnd) - is a complete implementation of a Lightning Network node. lnd has several pluggable back-end chain services including btcd (a full-node), bitcoind, and neutrino (a new experimental light client). The project's codebase uses the btcsuite set of Bitcoin libraries, and also exports a large set of isolated re-usable Lightning Network related libraries within it. In the current state lnd is capable of:

  • Creating channels.
  • Closing channels.
  • Completely managing all channel states (including the exceptional ones!).
  • Maintaining a fully authenticated+validated channel graph.
  • Performing path finding within the network, passively forwarding incoming payments.
  • Sending outgoing onion-encrypted payments through the network.
  • Updating advertised fee schedules.
  • Automatic channel management (autopilot).

Lightning Network Specification Compliance

lnd fully conforms to the Lightning Network specification (BOLTs). BOLT stands for: Basis of Lightning Technology. The specifications are currently being drafted by several groups of implementers based around the world including the developers of lnd. The set of specification documents as well as our implementation of the specification are still a work-in-progress. With that said, the current status of lnd's BOLT compliance is:

  • BOLT 1: Base Protocol
  • BOLT 2: Peer Protocol for Channel Management
  • BOLT 3: Bitcoin Transaction and Script Formats
  • BOLT 4: Onion Routing Protocol
  • BOLT 5: Recommendations for On-chain Transaction Handling
  • BOLT 7: P2P Node and Channel Discovery
  • BOLT 8: Encrypted and Authenticated Transport
  • BOLT 9: Assigned Feature Flags
  • BOLT 10: DNS Bootstrap and Assisted Node Location
  • BOLT 11: Invoice Protocol for Lightning Payments

Developer Resources

The daemon has been designed to be as developer friendly as possible in order to facilitate application development on top of lnd. Two primary RPC interfaces are exported: an HTTP REST API, and a gRPC service. The exported API's are not yet stable, so be warned: they may change drastically in the near future.

An automatically generated set of documentation for the RPC APIs can be found at api.lightning.community. A set of developer resources including guides, articles, example applications and community resources can be found at: docs.lightning.engineering.

Finally, we also have an active Slack where protocol developers, application developers, testers and users gather to discuss various aspects of lnd and also Lightning in general.

Installation

In order to build from source, please see the installation instructions.

Docker

To run lnd from Docker, please see the main Docker instructions

  • irc.libera.chat
  • channel #lnd
  • webchat

Safety

When operating a mainnet lnd node, please refer to our operational safety guidelines. It is important to note that lnd is still beta software and that ignoring these operational guidelines can lead to loss of funds.

Security

The developers of lnd take security very seriously. The disclosure of security vulnerabilities helps us secure the health of lnd, privacy of our users, and also the health of the Lightning Network as a whole. If you find any issues regarding security or privacy, please disclose the information responsibly by sending an email to security at lightning dot engineering, preferably encrypted using our designated PGP key (91FE464CD75101DA6B6BAB60555C6465E5BCB3AF) which can be found here.
