 In telemetry applications, certain objects like in our case e.g. the car, need to have an identity to conduct actions in the system. Ideally, this identity is not controlled by anyone, such that the device can truly act autonomously. For these use cases, in BigchainDB we will use decentralized identifiers (DID) which are identifiers intended for verifiable digital identity that is "self-sovereign". They do not dependent on a centralized registry, identity provider, or certificate authority. You can learn more about it in our [DID specification](https://w3c-ccg.github.io/did-spec/).
 So in our app, each object in the real world as the car, the telemetry box in the car, the GPS device, etc. will be represented by a DID. Each object will have a tag or cryptochip containing a securely hidden private key that serves as unique identity.
 
-You will create a DID class that inherits from Orm BigchainDB driver, so DID objects will have all of the methods available in Orm. The `entity` represents the public key of the object itself.
