Description
TL;DR: A short environmental comparison using Bitcoin mining and Ethereum's shift to proof of stake as its central examples.
About This Document
Surajit Mandal introduces blockchain creation, proof-of-work mining, electricity demand, and carbon concerns, then contrasts those features with proof of stake. The paper draws on period statistics and the Ethereum transition to argue that consensus design can materially change operational energy use.
Why Bitcoin People May Care
Energy comparisons depend on system boundaries, electricity mix, hardware, utilization, security assumptions, and the time of measurement. Proof of stake also changes governance and attack economics rather than simply substituting an identical mechanism. This is a 2023 primary overview, not a complete lifecycle assessment or current Bitcoin energy inventory.
