Anom provides a common trust environment that enables trusted data and business interoperability with billions of IoT devices. Anom registers a device's identity and reputation on an immutable blockchain-based ledger. Anom achieves this by collaborating with device manufacturers and other stakeholders, thereby facilitating an ecosystem of participants aimed at maintaining a decentralized consensus of device identity and reputation. Combining on-chain and off-chain resources, and built on the Ethereum blockchain, Anom's architecture can be extended by developers in IoT verticals (e.g., industrial IoT, healthcare, and smart cities) to help secure IoT A vast field of connected devices. Healthcare and home automation systems, smart city infrastructure, industrial sensors and controllers.
