 Recent events, such as the [https://twitter.com/MustafaYilham/status/1384278267067203590 ~25% hashrate crash due to coal-powered grid failure in china] and Tesla’s rescinding of its acceptance of Bitcoin as a form of payment, show that there are practical real-world downsides to Proof of Works’s massive reliance on energy.

 Whether on not the Bitcoin community accepts this common criticism as entirely valid, it has real-world effects which will only get worse over time. Eliminating the exponentially growing energy use currently built into Bitcoin without eliminating the security of PoW would be ideal and should not be a partisan issue.

 HeavyHash uses a proven digital hash (SHA3) packaged with a large amount of MAC (Multiply-and-Accumulate) computation into a Proof of Work puzzle. Although HeavyHash can be computed on any standard digital hardware, it becomes hardware efficient only when a small digital core is combined with a low-power photonic co-processor for performing MAC operations. oPoW mining machines will have a small digital core flip-chipped onto a large, low-power photonic chip. This core will be bottlenecked by the throughput of the digital to analog and analog to digital converters. A prototype of such analogue optical matrix multiplier can be seen in the figure below.

 Below is a conceptual representation of a 3D-packaged oPoW mining chip. Note that the majority of the real estate and cost comes from the photonic die and the laser, with only a small digital SHA3 die needed (as opposed to a conventional miner of the same cost, which would have many copies of this die running in parallel).
