It's pretty well established that CAPEX is the source of security in PoW not OPEX. See our paper and papers like httpss://uncommoncore.co/wp-content/uploads/2019/10/A-model-for-Bitcoins-security-and-t

Actually, electricity rates drop with economies of scale and willingness to set up in remote areas. Have you looked into mining Bitcoin with GPUs lately? You would need free GPUs and free electricity to justify the effort to set it up... BT

Hey, MD here... You are right that these tradeoffs are difficult to engineer. However, it's easier to make it work on top of a more radical shift in hardware. At the basic level, we are just using simple random matrix-vector mults. Of

For existing PoW, proximity to cheap energy is required before anything else.

The ratio of HW cost to energy use is different for each computing platform and depends on algorithm etc. For example, it seems Cuckoo Cycle PoW has somewhat higher capex/opex in ASICs because of the heavy memory use. For photonics the

Yes, more HW would be purchased. There's much less embodied energy in $1 of chip (especially cutting edge HW where you are covering R&D) than in $1 of energy. Also once hardware (access to capital much better distributed than acces
