It describes BoT-related common capabilities of the IoT reference model specified in [ITU-T Y.4000].

The scope of this Recommendation includes:

- introduction of blockchain of things;

- common characteristics and high-level requirements of BoT;

- relevant common capabilities and functionalities, and general procedures.

In addition, in appendixes, this Recommendation provides deployment modes, use cases, technical analysis and comparison, business roles and models to illustrate how BoT can provide alternative approaches for the improvement of IoT applications and services.
