Photonic Logic Chip
Interference fringes as logic gates no silicon, 5mW @ 50GHz
What it does
Logic functions defined by light beam angles on liquid-crystal film — no silicon etching, no waveguides required. An interference fringe IS a logic gate. Verified: 400 GIPS (8-core), 5.289mW @ 50GHz, 10ps latency, hardware PUF security (7/8 cores compromised = 0% leakage). 28 technical claims, CERN DOI published, FDTD simulation done. Standard draft PLC-STD-001 submitted. Open for licensing.

Inspired by games like Turing Complete/Virtual Circuit Board/Logic World, I tried to make a mix of aseprite and wiredworld/wired-logic, the idea being the user can build a digital circuit using a "fullstack" pixelart creation workflow. The circuit is just an image. The primitives are (i) connected wires which have undefined, 0 or 1 state during simulation (displayed brighter or darker in function of the state) and (ii) NANDs, which are little pixel triangles. During simulation the user can interact with any wire by clicking on it, toggling its state, which is cool for messing…
- ZCzkGolf – Competitive optimization of formally verified circuitsJul 2026 · zk.golf · ▲69
Zero-Knowledge Proofs (ZKPs) let an untrusted proved show that computation was executed correctly without revealing the inputs to the verifier. However to prove anything, the computation first has to be expressed as a circuit: a system of polynomial equations (constraints) over a finite field. Circuits are the assembly language of zk and every constraint costs prover (and sometimes verifier) time, so production circuits are aggressively hand-optimized. Over the last months, we have been experimenting with writing formal specifications instead and letting LLMs produce the circuits: as long as…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
