For long, Virtual Private Networks (VPNs) have been a viable solution for preserving one's privacy and anonymity. In today's world, there are many VPN services which rely on a middleman (or a central operator) that could be paid with Fiat or crypto. But what if we'd eliminate the middleman from the system, and bring a self-autonomous VPN service to the world using Blockchain technology? In this model, people would pay for a VPN service that will last for "x" amount of days using a crypto of their choice. Everything will be settled on-chain in a completely decentralized way. Node operators would serve as "gateways" that would constitute the whole VPN.

So far, I'm aware of two Blockchain-based VPN services (Mysterium and Tachyon Protocol) which aim to further decentralize the Internet by eliminating the need to rely on a middleman or third parties for complete privacy/anonymity. But compared with traditional VPN service providers, Blockchain-based VPN services are a "needle in a haystack".

Do you think that VPNs using Blockchain technology are worth it? Is it still too early too tell? Do you happen to know about other alternatives to Mysterium or Tachyon Protocol within the Blockchain industry? What are your thoughts?
