Abstract
A smart city refers to an intelligent environment obtained by deploying all available resources and recent technologies in a coordinated and smart manner. Intelligent sensors (Internet of Things (IoT) devices) along with 5G technology working mutually are steadily becoming more pervasive and accomplish users’ desires more effectively. Among a variety of IoT use cases, e-voting is a considerable application of IoT that relegates it to the next phase in the growth of technologies related to smart cities. In conventional applications, all the devices are often assumed to be cooperative and trusted. However, in practice, devices may be disrupted by the intruders to behave maliciously with the aim of degradation of the network services. Therefore, the privacy and security flaws in the e-voting systems in particular lead to a huge problem where intruders may perform a number of frauds for rigging the polls. Thus, the potential challenge is to distinguish the legitimate IoT devices from the malicious ones by computing their trust values through social optimizer in order to establish a legitimate communication environment. Further, in order to prevent from future modifications of data captured by smart devices, a Blockchain is maintained where blocks of all legitimate IoT devices are recorded. This article has introduced a secure and transparent e-voting mechanism through IoT devices using Blockchain technology with the aim of detecting and resolving the various threats caused by an intruder at various levels. Further, in order to validate the proposed mechanism, it is analyzed against various security parameters such as message alteration, Denial of Service (DoS) and Distributed Denial of Service (DDoS) attack and authentication delay.

The accelerated pace of urbanization in the recent decades has endangered the environment and economic sustainability by raising several social, technical and economic concerns
Smart industry, smart grid, smart healthcare, public safety, secure e-voting and water management are the various developments related to smart cities that are being retro fired with IoT and smart sensors
Among a variety of IoT use cases, e-voting is a considerable application of IoT that relegates it to the phase in the growth of technologies related to smart cities and provides intrusion-free democratic procedures for the citizens of these cities [8], [9]
Summary
The accelerated pace of urbanization in the recent decades has endangered the environment and economic sustainability by raising several social, technical and economic concerns. With the usage of 5G technology, the huge volume of data generation, processing, sharing, analyzing and storing leads to a number of privacy and security concerns such as identify theft and/or Denial of Service (DoS), man-in-middle attack etc Future research in this technology is crucial for the advancement of IoT technology in general and smart cities in particular. Blockchain technology can meet the demand for transparency, request for which is increasing at an astounding pace It can ensure security and transparency among the devices even though IoT objects may be hacked by intruders as any alteration with the data can be detected.
