How do decentralized virtual private networks operate? (November

A decentralized virtual private network (VPN) modifies conventional VPN technology by dividing network functions among several nodes instead of directing traffic via centralized servers. The theory behind it is that by having a dispersed structure, users may benefit from improved privacy and security. Furthermore, dVPN could be more censorship-resistant. But things aren’t usually that simple.

First of all, what is a VPN?

With a VPN service, all of your internet traffic is routed over a secure tunnel that is invisible to outside observers. By prohibiting third parties from listening in on your activities, this encryption guarantees the secure transmission of your data. With a VPN, you may look as though you are connecting from a different country while maintaining more privacy by substituting your real IP address with a new one. All of this is readily accomplished with a single app touch or click.

How operates a VPN that is decentralized?

A decentralized VPN, often known as a dVPN, differs from a traditional or centralized VPN in that it routes traffic across a global network of dispersed nodes run by diverse people rather than through servers owned and maintained by one organization. With this method, data handling is radically altered with the goal of providing improved security and privacy. This is an explanation of how it functions:

network of peers. A decentralized VPN functions primarily via a peer-to-peer (P2P) network architecture. Instead of connecting to the service via fixed, specialized servers, users connect over a network of nodes that other users voluntarily offer. By functioning as a tiny, temporary server, each node builds a highly robust, dispersed network.

public IP address. There isn’t much control over the user’s location because of the P2P structure of the network, which means that its public IP address will be the last node it connects to. It does, however, have the advantage of allowing you to utilize the volunteer’s home IP address to get beyond firewalls that restrict recognized VPN IP addresses.

routing and encryption. Similar to a standard VPN, your internet traffic is encrypted when you connect to a decentralized VPN. Nevertheless, your data packets are divided into smaller bits and routed over several network nodes rather than passing via a single server. The multi-hop routing technique greatly increases the difficulty of data tracking and interception by hackers.

no single governing body. Decentralized VPNs eliminate the possibility of a single point of failure or attack because there is no central authority in charge of the network. Because of this structure, user privacy is improved and it becomes more difficult for governments, ISPs, or hackers to monitor or restrict user activities.

token-based financial system. Blockchain technology is used by several decentralized VPNs, which run on a token economy. By letting their device serve as a node, users may earn tokens. They can also buy tokens to access the network. This promotes involvement and aids in network scaling while preserving security and privacy.

Decentralized VPNs may offer a solution for those in high-censorship nations who wish to access the internet, because standard VPNs have been known to be blocked in these countries. This can happen through technical means of breaking connections or by banning websites that allow downloads and purchases. If you want strong privacy, nevertheless, dVPN might not be the greatest option.

Is Tor and decentralized VPN interchangeable?

To put it succinctly, no, but it doesn’t mean they aren’t similar in certain ways, especially since both methods encrypt your connection and pass it across many nodes. They have distinct architectures and operating concepts, nevertheless.

The Onion Router, or Tor for short, is a network of volunteer-run relays or nodes that is intended to anonymize user traffic. When utilizing Tor, internet traffic is encrypted and sent across a number of relays, each of which removes a layer of encryption before the data reaches its destination—thus the term “onion.”

A decentralized virtual private network, or dVPN, uses a decentralized network that is frequently based on blockchain technology to encrypt and route traffic over several nodes. In contrast to Tor’s relay layers, anybody who is willing to share their internet connection can run dVPN nodes, and blockchain technology can be used to encrypt and anonymize network transactions.

Are VPNs with decentralization safer than those with centralization?

This question is far more complicated than it first seems. To put it briefly, the answer is that because you’re effectively entrusting more individuals with your data, decentralized VPNs may actually be riskier than centralized VPNs. But let’s take a closer look.

Foundations that are open-source

The fundamental functions of both dVPNs and conventional VPNs are based on open-source protocols like OpenVPN. Due to its open-source nature, vulnerabilities may be found and fixed by the community via examination. VPN service providers may, however, use different protocols in different ways. While dVPNs highlight the openness of their open-source apps, traditional VPNs gain from the security and dependability of open-source underpinnings.

Centralized vs. decentralized server architecture

Data is dispersed over a network of user-operated nodes via dVPNs, which may increase the number of parties that have access to it. Conventional VPNs, on the other hand, direct traffic via servers under central control. Although this central control may appear to be a single point of failure, it also allows a reliable VPN service to concentrate confidence in one single, responsible body by enforcing stringent security standards and undergoing audits to confirm their no-logs policy.

Risks of server compromise

Because dVPNs are decentralized, it only takes access to one node to compromise user privacy as opposed to several nodes in networks like Tor, which are meant to prevent any one point from viewing the full picture of a user’s behavior. Because centralized VPNs employ servers located in data centers, they are also more difficult to hack. Due to their structure, dVPNs may be more vulnerable to deliberate attacks by affluent enemies.
