This commit fixes a bug related to swallowing an error that should go to the switch in the case of an insufficient balance error when attempting to add a new HTLC to the channel state machine. In this case, an error would never be returned back to the client/switch, and the internal processing within the channelLink would loop forever, attempting to add an HTLC that can’t be added due to insufficient balance to state machine itself. We fix this issue by only treating the lnwallet.ErrMaxHTLCNumber as the only error that prompts adding an HTLC to the overflow queue rather than sending the error directly back to the switch. |

Lightning Network Daemon
The Lightning Network Daemon (lnd
) - is a complete implementation of a
Lightning Network node and currently deployed on
testnet3
- the Bitcoin Test Network. lnd
has several pluggable back-end
chain services including btcd
(a
full-node) 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
doesn't yet fully conform to the Lightning Network specification
(BOLTs). BOLT stands for:
Basic of Lightning Technologies. 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, lnd
the current status of lnd
's BOLT compliance is:
- BOLT 1: Base Protocol
- BOLT 2: Peer Protocol for Channel Management
lnd
has not yet integrated full channel re-transmission upon reconnection
- 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
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 talks, articles, and example applications can be found at: dev.lightning.community.
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.
