摘要
The rapid growth of cryptocurrency with computationally intensive mining processes has significantly impacted global energy use. Recently in Frontiers in Energy Research, Zade and colleagues developed a generalized scenario model to evaluate the power demand of proof of work blockchain mining. It was determined that mining algorithmic complexity-not advances in hardware efficiency-is the prime factor determining the energy consumption of Bitcoin and Ethereum. Blockchain applications must transition from proof of work toward energy-efficient consensus algorithms to be sustainable.
