3 datasets
Daily snapshots of the peers connected to KIT's Bitcoin monitoring nodes, one JSON file per day with each peer's services, version, user agent, autonomous system, coarse location, relay statistics and latency. The monitor connects to reachable nodes and records what they relay, following the group's published methodology. Useful for studying the node population and propagation over many years; peer IP addresses are anonymised.
Timestamps at which blocks arrived at various Bitcoin nodes, one CSV file per node with height, hash and millisecond arrival time. Contributors extract the timestamps from their Bitcoin Core debug logs with the included script, and CI checks them against the block header time. Useful for measuring block propagation delay; coverage differs by node and period.
Lightning Network gossip messages as sent and received by instrumented LDK nodes, with microsecond timestamps per message, peer and direction, published as monthly Parquet archives. The collectors connect to peers chosen across network communities and export their captures to Zenodo. Useful for studying gossip propagation, fanout and peer sync behaviour; messages sent by collectors are mostly replies to sync requests, not relays.
