The Internet of Things is currently an extremely fragmented market, where a thermostat may connect to a smartwatch, but is unable to connect to a Smart TV or connected door lock. To reduce fragmentation and improve security, Chronicled, a smart tag authentication startup, has open sourced a program—based on the Ethereum blockchain—that registers IoT devices in an open database.

In an example Chronicled CEO Ryan Orr provided to CoinDesk, a smart window verifies an Amazon drone’s intention and lets it deliver a parcel.
