    Internet of Things is defined as the framework of interconnected computing systems, mechanical and digital appliances, objects, animals, or people that are equipped with specific identifiers as well as the ability to transfer data over networks. Such devices will not require human-to-human or human-to-computer interaction. This technology has emerged with a Blockchain, which has been used in cryptocurrency, to enhance the performance of security and decrease costs. Although emerging Blockchain with IoT has improved the entire system design. It still faces a number of issues relevant to time latency, anonymity, power efficiency, and big data. Blockchain has been used in various applications such as Healthcare, smart homes, and smart cities. In this paper, we will briefly define the idea of Blockchain including the definition of Blockchain, its types, advantages, and disadvantages, and then present some challenges of Blockchain-based applications on the Internet of things where we focus on Healthcare, smart homes, and smart cities. Finally, some future work direction will be introduced.

    ConferenceCITISIA 2020 Conference
    OtherThe “Conference on Innovative Technologies in Intelligent Systems & Industrial Applications” (CITISIA) is a student conference that aims to provide students of higher learning institutions with a platform for presenting their own projects. It is also a measure of recognition of students’ professional and technical achievements – by industries and international organizations such as IEEE. This conference is designed to facilitate exchanges of ideas through communication, networking and learning from others, for students and IEEE Chapters in terms of greater collaboration.
    The conference provides a unique platform for students and researchers to share their experience and views through their latest research and to promote research and development activities among students and researchers. CITISIA 2020 provides an international forum for those actively involved in research to report on latest innovations and developments, to summarize state-of-the-art works, and to share ideas and advances from all aspects of engineering, where advances play an increasing role in providing enriching experiences and improving the quality of lives.
