Atonomi provides a new security protocol and infrastructure to enable billions of IoT devices to have trusted interoperability for both data and commerce. The key innovation of the Atonomi protocol is to root the identity and reputation of devices on a blockchain-based immutable ledger. Atonomi accomplishes this by building and facilitating an ecosystem of participants designed to maintain decentralized consensus for device identity and reputation on the Atonomi Network.
