To begin with, a dVPN is not based on a central server like VPN. In fact, it is spread across the node, thus more safe and secure. Decentralized VPNs are more efficient than classic VPNs. One can select their own servers and have no limits of choices. Furthermore, dVPN are cost-effective. They neither log nor track users, and can't sell the gathered data. Also, Dvpn is blockchain-driven and thus has scope to improve and be more secure.
