Bitcoin developer launches privacy-focused Nostr VPN using public keys
ReadOne of the earliest Bitcoin developers launched a new privacy-focused version of Nostr VPN that replaces centralized identity providers with cryptographic keys.Martti Malmi, an early Bitcoin developer who worked with Satoshi Nakamoto, has published a new privacy-focused version of Nostr VPN inspired by Tailscale, replacing email addresses and third-party accounts with Nostr public keys.Malmi said in a Tuesday X post that the new version of Nostr includes a multiplatform interface for managing VPN settings across devices, as well as Nostr-based multihop routing that acts as a fallback system when direct peer-to-peer connections fail.The new version uses Nostr cryptographic keys instead of email logins or third-party accounts, reducing reliance on centralized services. The project aims to offer a more decentralized alternative to traditional VPN providers that route traffic through company-controlled servers.VPNs, or virtual private networks, create encrypted connections between devices and the internet to help hide users’ IP addresses and internet traffic.Source: Martti MalmiBitcoin advocate Swiss Hodler called decentralized VPNs “freedom technology” that makes online censorship more difficult as it helps remove more infrastructure from “centralized control.”Malmi, also known as “Sirius,” is a Finnish computer scientist and developer who was known as one of Nakamoto’s first major collaborators between 2009 and 2011. Malmi helped design Bitcoin’s first graphical user interface, co-managed Bitcoin.org and co-founded the Bitcoin Forum, later rebranded as Bitcointalk.Related: Capital B boosts Bitcoin reserves with $15.2M purchaseInternet users seek privacy-focused VPN solutionsDevelopers have been building more decentralized VPNs to answer the growing user demand for privacy-focused solutions.ZeroTier launched in 2013 as one of the first privacy-focused VPN solutions that were built on a private mesh network. By 2024, ZeroTier said it had garnered over 3 million connected devices across 5,000 paid accounts and 600,000 network administrations.In 2017, a community of open-source developers launched Yggdrasil, a decentralized mesh network that functions similarly to a VPN by connecting devices through end-to-end encryption without relying on centralized servers.Yggdrasil network architecture.
