Webphotonic implementation and performance of optical proof of work, we must rst clarify the energy-e ciency problem in blockchain and cryptocurrency. Cryptocur-rency is a decentralized currency market where transac-tions (e.g. \Alice gives Bob 1 bitcoin") are stored in a chain of blocks (\blockchain"). To earn a share of the Webcurrent size, the authors propose a novel PoW algorithm, Optical Proof of Work (oPoW), to eliminate energy as the primary cost of mining. Optical Proof of Work imposes economic difﬁculty on the miners, however, the cost is concentrated in hardware (capital expense—CAPEX) rather than electricity (operating expenses—OPEX).
