Virtual private networks (VPNs) can be useful for all kinds of things, from streaming foreign sports to protecting your identity from heightened online surveillance. For cryptocurrency users, VPNs are particularly precious, providing access to exchanges that are geo-restricted, and enabling crypto activities to be completed on the web without leaving a privacy-betraying footprint.

The Rise of the VPN
Virtual private networks can be traced back to 1996 when a Microsoft staffer conceived a peer-to-peer tunneling protocol (PPTP). In many ways, the protocol functioned as a precursor to the VPNs we see today, providing a private, secure connection between a computer and the world wide web, as it was then known.
The advantages of having a permanently encrypted conduit to the web are manifold. Think about how often you unwittingly connect to insecure public wifi, for example, with everything from credit card numbers and social media log-ins vulnerable to theft. A VPN, which lets you connect to a remote server while masking your true location, provides peace of mind by safeguarding data from third-party interception. Virtual private networks also block persistent IP tracking, which is trickier to prevent than insidious third-party tracking e.g. from Google.
The Quest to Decentralize the VPN
VPNs can mitigate the worst data intrusions of centralized agencies (be it tech giants or governments), but they themselves are vulnerable to flaws inherent to centralization. This month, it emerged that popular provider NordVPN suffered a data breach in 2018 when a Finnish server in a rented data center was compromised. Although the company has asserted that no usernames or passwords were intercepted, the fiasco proves that VPNs are not invulnerable to the very attacks they endeavor to protect
