The blockchains technology (BT) and IoT are pondered emerging approaches that can change our lives in the next generation computing. The BT is much secured and authentic than other technologies. It can be optimistic to provide us high trust in the secure transactions in the heterogeneous network where everything with connecting and talks to each other [1]. Fog computing can play an important role in IoT and BT network. It can compute, store and control the transaction. The IoT is the ongoing research to connect the physical objects, machines and embedded devices to wireless communication and the internet. According to the Statista report, the IoT connected devices will reach more than 75 billion up to 2025 [2]. This report shows us the importance of the proposed framework.
