# Lightning Network Gossip — Channel Closure Dataset
Daily snapshots of the Lightning Network (LN) collected from gossip messages
between **2022-06-09** and **2024-10-14**. Used in the paper *Predicting
Channel Closures in the Lightning Network with Machine Learning* (Antonelli
et al., 2026; [arXiv:2605.12759](https://arxiv.org/abs/2605.12759)) and
consumed by the
[ln-channel-closure-prediction](https://github.com/AmbossTech/ln-channel-closure-prediction)
codebase.
## Schema (one row per gossip event)
| Column | Description |
|---|---|
| `chan_id` | Lightning channel identifier (`block:tx_idx:vout`). |
| `transaction_id`, `transaction_vout` | Funding transaction reference. |
| `last_update` | Last gossip update timestamp (ms). |
| `capacity` | Channel capacity (sat). |
| `src`, `dst` | Endpoint public keys (hex). |
| `src_*`, `dst_*` | Per-direction routing policy: time-lock delta, htlc bounds, fee base/rate, disabled flag, max-htlc, last-update timestamp. |
| `channel_status` | `OPEN` / `CLOSED`. |
| `closing_info` | `OPEN` / `MUTUAL` / `FORCED` / `LOCAL_CLOSED` / `PENALTY_CLOSED`. |
| `src_alias`, `dst_alias`, `src_implementation`, `dst_implementation` | Endpoint metadata. |
| `gossip_ts` | Event observation timestamp (ms). |
| `ts`, `height`, `block_avg_fee_rate` | On-chain funding metadata. |
## Statistics
- **Events:** 693 277.
- **Unique nodes:** 36 170.
- **Class distribution at prediction time** (over open edges):
open ≈83 %, mutual ≈9 %, forced ≈8 %.
## Notes on the initial snapshot
The first day (2022-06-09) carries the entire pre-existing LN state as a
single batch of artificial "openings" — about 38 % of the rows. The
benchmark's `warm_start` mode initialises from these events without using
them for training/eval.
## License
Dataset is released under **CC-BY-4.0**. The underlying gossip messages are
public by design.
