Understanding Blockchain Sustainability Beyond Bitcoin
summary
A PwC-built framework applies a bottoms-up measurement of hardware, node networking and data transmission to quantify Stellar Core and Horizon energy use, finding a surprisingly small footprint roughly equivalent to 34 U.S. homes of annual electricity (later reduced to ~17 after engineering tweaks). The methodology produces a 60‑page benchmark, identifies which architecture knobs to toggle, and leads to carbon removal commitments plus an ecosystem invitation to reduce and verify real-world emissions.
