| # 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](https://huggingface.co/papers/2605.12759) (Antonelli |
| et al., 2026, under review) 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. |
