Photonic chips for analog matrix processing are already being commercialized.
The underlying platform, CMOS Silicon Photonics is commercial already (in every data center) and produced in high volume.
Heavyhash can be constructed such that the Keccak hashes comprise a minimal amount of the work.
Quoting from the BIP:
"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)."
- jl2718 5y agoFirstly I'm not convinced that the photonic version would be more efficient than the all-electric version. The conversion is very expensive. Secondly, they don't need to be on the same chip. The Sha3 chip would be very dense, and the multiplex in time and frequency into the photonic circuit, which would have much larger features, probably printed on silica.
- Mdubrov 5y agoAre you familiar with silicon photonics? (though indeed they probably would not be on the same chip as we point out in the BIP) We have a short primer on Si photonics in our paper actually https://assets.pubpub.org/xi9h9rps/01581688887859.pdf https://assets.pubpub.org/xi9h9rps/01581688887859.pdf
