ABSTRACT
For the past few years, the topic of “fake news” has been consistently featured prominently in the news headlines. Fake news is a serious problem that jeopardises a society’s political, social, democratic, and economic institutions. The usage of the Internet and social media has exacerbated the situation. Technology plays a significant part in the dissemination of fake news, but it may also play a significant role in combating fake news. The blockchain technology (BCT) is a new form of disruptive technology that has captured the interest of a significant number of researchers due to the exceptional security characteristics it possesses and the transparency it offers. BCT ensures the provenance, authenticity and traceability of data by producing a record of transactions that is open to inspection, cannot be altered, and can be independently verified. The purpose of this chapter is to investigate the use of BCT in the fight against fake news. To do so, we will first examine the characteristics of blockchain technology, and then we will discuss the difficulties that BCT faces. In addition, a number of suggestions are provided as a roadmap for future researchers on topics that will need to be addressed in order to combat the spread of fake news.
