    Fabric Cryptography

    Programmable silicon targeting cryptographic primitives generally, not one proof system. The instruction set is being co-designed with Polygon Labs around Plonky2/Plonky3. Prototype cards have shipped; no public third-party throughput benchmark exists, so none is plotted.
