Title: Photonic SHA256 ASIC Implementation Post by: lucaselc on September 29, 2025, 11:44:44 PM Hi everyone,
I’m studying photonics in my university course, and I’ve recently developed an interest in integrated photonics. I decided to focus my final graduation project on photonic computation, combined with another field of interest to me: Bitcoin BTC. My goal is to design, at least in simulation, hardware capable of performing SHA-256 hash calculations using photonics — ideally fully optical and, if possible, leveraging WDM-based hardware parallelism. Do you have any concerns about my project? I would like to hear feedback from an outside perspective. Any advice is welcome!

Photonics are only good for high bandwidth interconnections. Physics/manufacturing processes are not there yet to minimize the photonic elements to transistor sizes needed for a truly "photonic" hash engine. |
