The chain mints a fixed number of PRL per day, set by height alone. So cost per coin is network spend divided by emission — and it scales linearly with hashrate.
Every control re-runs the model server-side against the full difficulty history.
Solid to today, dashed beyond. Log scale — early-chain costs were orders of magnitude lower.
Throughput figures disagree between sources — the range column is the honest spread, not a precision claim.
What miners actually pay versus posted industrial tariffs — a ~5× gap. Averaging the two would wreck the model, so they are kept separate.
