November 21, 2023 - Around 4 mins mins to read

Tor, originally known as The Onion Router, is a decentralized network that ensures anonymity by encrypting internet traffic and directing it through a series of servers before reaching its final destination. It was developed to protect user privacy, especially in an era of increasing online surveillance and censorship. Understanding how Tor works and its various applications is essential for navigating the complex world of blockchain and decentralized technologies.

The Tor network functions by routing each user’s traffic through three random nodes, or relays, before transmitting it to its intended endpoint. Each stage of the journey is encrypted independently, and each relay only knows the traffic’s previous origin and its immediate next destination. As a result, no node can possess the complete path of any traffic, as per the network’s design.

For example, let’s say User A wants to access a website anonymously using Tor. User A’s traffic is encrypted and sent to the first relay, which only knows User A’s IP address and the IP address of the next relay. The first relay decrypts the initial layer of encryption and forwards the traffic to the second relay, which decrypts another layer and forwards it to the third and final relay. The final relay decrypts the last layer and sends the traffic to the destination website. This multi-layered encryption and routing process make it extremely difficult for anyone to trace the origin of the traffic back to User A.

The Tor network is primarily known for its role as a gateway to dark web sites and marketplaces accessible via “.onion” addresses. The dark web refers to websites that are not indexed by traditional search engines and require specific software like Tor to access them. One of the most infamous marketplaces was Silk Road, which has since been shut down. Silk Road allowed users to anonymously purchase illegal goods, such as drugs and counterfeit driver’s licenses, using Bitcoin (BTC).

However, Tor is not limited to facilitating illicit activities. It is also used by journalists, activists, dissidents, and whistleblowers who require online anonymity for their safety and security. In countries with oppressive regimes, journalists and activists often rely on Tor to evade government surveillance and censorship, allowing them to communicate and share information without fear of repercussions.

Law enforcement agencies and intelligence services also use Tor in certain cases. For instance, they may create their own hidden services, accessible only through Tor, to gather intelligence on criminal networks or monitor illegal activities. By using Tor, these agencies can operate undercover while still maintaining anonymity.

Another important aspect of Tor is the Tor Browser. Developed by the Tor Project, the Tor Browser is an open-source internet browser that automatically routes traffic through the Tor network. It is designed to make it easy for users to access the Tor network without requiring technical expertise. The Tor Browser prevents websites from tracking user activity and provides a layer of anonymity beyond what traditional browsers offer.

In recent years, the Tor network has faced criticism for potentially enabling illegal activities. However, it is essential to recognize that Tor itself is a neutral technology. It provides a tool for privacy and anonymity, which can be used for both legitimate and illegitimate purposes. Just like any technology, it is the users who determine how it is utilized.

From a blockchain perspective, Tor can be advantageous for individuals seeking to engage with decentralized networks and applications anonymously. It offers an additional layer of privacy and security when interacting with blockchain platforms that prioritize user anonymity. By using Tor in conjunction with blockchain technology, individuals can protect their identities and engage with the blockchain ecosystem without revealing their real-world information.

In conclusion, Tor is a decentralized network that allows users to browse the internet anonymously by encrypting and routing internet traffic through a series of relays. It provides a crucial tool for individuals seeking to maintain privacy and bypass surveillance. While primarily known for its association with the dark web, Tor is also utilized by journalists, activists, law enforcement agencies, and others who require online anonymity. Understanding Tor is important for individuals interested in blockchain technology and decentralized applications, as it offers an additional layer of privacy and security when engaging with these networks.
