The book begins by defining the dark web and its technological underpinnings, such as Tor and blockchain. It progresses by analyzing different types of dark web communities, including criminal forums, fringe social networks, and platforms for political activism. The analysis is based on direct observation, leaked data, and expert interviews, providing a comprehensive perspective. This approach helps in understanding the human element driving these networks, offering a nuanced portrayal of their complexities, rather than sensationalizing criminal activities.
