writing my thesis on Lightning Network structural centralization.

Trying to close one remaining edge-level data gap in a longitudinal LN dataset spanning 2019 to today. Looking for **gossip_store dumps or rotated logs from a CLN node covering October 2024 to July 2025**.

What I already have:

* 2019 to August 2023 from the Decker archive (via Valko & Marx Gomez 2025)
* August 2023 to October 2024 from Amboss's open ln-gossip dataset on HuggingFace (CC-BY-4.0, published a few days ago)
* August 2025 to today from Vilnius University blnstats

The 9.5 month window from October 2024 to July 2025 is the only piece left. Any CLN node operator who kept archival gossip_store backups from that period would be a huge help.

Format I need is the raw gossip_store binary (not the compressed/anonymized GOSSMAP_COMPRESSv1 variant in CLN tests/data, since that strips short_channel_ids and signatures). What I would do with it is parse channel_announcement and channel_update messages, reconstruct biweekly snapshots, and add the bridge tier to the longitudinal dataset.

if anyone can help out it would mean the world to me.
