<p>The fog computing is the emerging technology to compute, store,
control and connecting smart devices with
each other using cloud computing. The
Internet of Things (IoT) is an architecture of uniquely identified interrelated
physical things, these physical things are able to communicate with each other
and can transmit and receive information. <a>This research
presents a framework of the combination of the Internet
of Things (IoT) and Fog computing. The blockchain is also the emerging technology
that provides a hyper, distributed,
public, authentic ledger to record the transactions. Blockchains technology is
a secured technology that can be a boon for the next generation computing. The
combination of fog, blockchains, and IoT
creates a new opportunity in this area. In this research, the author presents a middleware framework based on
the blockchain, fog, and IoT. The
framework is implemented and tested. The results are found positive. </a></p>
