Replication package: Energy use and CO2 emissions of proof-of-work cryptocurrencies from a marginal-miner condition

Code and cleaned data that reproduce every number, table, and figure in the manuscript. One-command rebuild via build_v2/run_all_v2.sh (Stata MP 18.5, Python 3.12, PyMC 5.x, JAX 0.4.x). Raw minerstat feeds are excluded per source terms; the bundled fetch scripts reproduce them. See README.md.
