Resolving the Kardashev's Conundrum Using a Bitcoin-Inspired Metric
Researchers led by Sebastian Gurovich introduce the Kardashev‑Sagan‑Nakamoto (KSN) model, which redefines civilization advancement by measuring energy‑to‑information efficiency using the Bitcoin network’s ASIC hashrate. By anchoring the metric to the Landauer limit, the model quantifies waste and computational thermodynamics, producing a timeline that places humanity’s Type II/III transition billions of years beyond the Sun’s lifespan. The study challenges the original Kardashev exponential forecasts, offering a linear OLS projection of roughly 1.6 × 10¹⁶ years. These findings provide a new quantitative language for SETI and the Drake equation’s longevity term.
