The decentralized VPN protocol Mysterium raises node trust concerns due to its P2P structure. While its open-source, blockchain-based design ensures no centralized logging, relying on individual node providers introduces risks. Exit nodes can potentially see unencrypted traffic, similar to Tor, and malicious nodes could enable man-in-the-middle attacks. DNS leaks and the absence of features like a kill switch further erode trust. Although Mysterium’s encryption (WireGuard, OpenVPN) is robust, users must implicitly trust node operators, especially in early development. Decentralization enhances privacy but complicates accountability, as node runners are everyday individuals, not vetted entities. For Mysterium to gain trust, it needs enhanced security features, rigorous node vetting, and transparent reputation mechanisms to ensure safe, reliable operation.
