Lumen Fingerprints

Surveys how Bitcoin transactions are built — script types, ordering, nSequence, sighash, feerate rounding, amounts, change — and reports how identifying each fingerprint is.

Dashboard

nix run .#dashboard

Opens a local Explorer; click Run a scan or browse the field catalog.

CLI

lumen scan   --datadir <dir> --out epochs.jsonl    # scan a block range via Floresta
lumen report --epochs epochs.jsonl --out-dir out/  # aggregate into report.json

A scan covers up to ~20k blocks — Floresta's assume-utreexo floor (height 939,969) to the chain tip. nix run .#scan does scan → report → serve in one command.
