Fabric Cryptography

Established in 2022 and based in California, US, Fabric of Truth, Inc. trading under the name Fabric Cryptography operates as a developer of programmable chips hardware for cryptography. In August 2024, Fabric of Truth, Inc. raised USD 33 million in series A funding co-led by investors Blockchain Capital and 1kx, with participation from other investors Offchain Labs, Polygon Labs, and Matter Labs.

The firm as of August 2024, is led by its co-founders, Michael Gao (CEO), Tins Ju (CSO), and Sagar Reddy (VP). Fabric Cryptography focuses on advancing cryptographic technology through its hardware solutions. Fabric's flagship product, the Verifiable Processing Unit (VPU), integrates features from GPUs and ASICs to create a chip optimized for cryptographic tasks. This chip offers speed and flexibility, handling complex cryptographic algorithms like plonky2 and TFHE with efficiency.

The VPU’s design includes custom silicon, a RISC-V multi-core processor, and a non-blocking network-on-chip, which collectively enhance performance far beyond traditional CPUs, GPUs, or FPGAs. The firm also offers a compiler and library software that leverages advanced optimization techniques to enhance performance across major algorithms including plonky2, plonky3, GKR, etc. Fabric Cryptography focuses on advancing cryptographic technology through its hardware solutions.
