4/ You know, that’s why we built Roc Camera

We wanted to build a camera that takes verifiably real photos in an age where the veracity and trust of digital media have eroded

Roc camera captures verifiably real moments using sensor attestations, client side zero-knowledge proofs, and TEEs - to bring back legitimacy

small brain (TEEs) crypto ✨find me on #tee-s

Hey yeah we use TEEs

Prob OP-TEE with RPi4

We’re planning to use TF-M ARM trust zone that comes with Zephyr RTOS that we can implement on specific microcontrollers. We did think about rolling our own FPGA TEE for awhile but thats for another time.

Zephyr RTOS can run TF-M (trusted firmware module) for a bunch of ARM cortex m0 to m3 chips
