Fabric Cryptography

Fabric Cryptography (legal entity Fabric of Truth, Inc.) is a Santa Clara, California semiconductor company founded in 2022 that builds the Verifiable Processing Unit (VPU) — a custom silicon chip whose instruction set is designed exclusively for the mathematical building blocks of modern cryptography. The VPU combines the programmability of a GPU with the performance of an ASIC: hundreds of number-theory units for 32-bit to 384-bit modular arithmetic, custom hash instructions, software-controlled scratchpad memory, a non-blocking network-on-chip, and an on-chip multi-core RISC-V processor for native witness generation. Products announced are the FC 1000 chip, the VPU 8060 card (three FC 1000 chips, ~1 TB/s memory bandwidth to 30 GB) and the "Byte Smasher" server (up to eight VPU 8060 cards). Software is an LLVM-based compiler plus a reconfigurable library of primitives targeting plonky2, plonky3, GKR, halo2, Jolt/Lasso, Nova and TFHE, with a stated future cloud offering. The company raised $33M in 2024 from Blockchain Capital, 1kx, Inflection and Protocol Labs, and has announced collaborations with Polygon Labs (AggLayer) and RISC Zero (Boundless). As of this pass Fabric publishes no developer program, API, SDK registry package or machine-readable specification of any kind.

  detail: Fabric Cryptography's entire public site is seven Webflow pages (home, blog index and four posts) with no developer,
    docs, API or SDK section, and every access path it does advertise is dead — the Co-Design, Pre-Order and Contact Typeforms
    all redirect to Typeform's generic "incorrect URL" page and the Lever careers board 404s; its two GitHub organizations
    (f16y, FabricCryptography) exist but hold zero public repositories.
