WebJul 2, 2024 · In this work we formally define three properties that are necessary for wasteless PoW systems: (1) solve "meaningful" problems (2) solve them efficiently and (3) be secure against double-spend attacks. We analyze these properties and deduce constraints that impose on PoW systems. In particular, we conclude that under realistic … WebMining using photonics – known as Optical Proof-of-Work (OPOW) – will shift the mining industry from operational costs to capital expenditures, as electricity usage drops substantially when using light as a medium of data transfer, rather than electrons.
