Vitro is an IoT platform based on AWS IoT. The Vitro Crystal gateway runs Vitrobian open-source stack for AWS Greengrass with ECC508A. https://devices.amazonaws.com/detail/a3G0L00000AAOCmUAP/Vitrobian-Crystalhttps://github.com/VitroTech/Vitrobian The Crystal gateway communicates with Shard edge devices via CAN bus. Shard is based on STM32 stack. The goal of our project is to build Shard plus ECC608A to hash data with Proof-of-Origin with PKI. These IoT Blocks can be used as authenticated data for blockchain applications.
