¡Nostr VPN ya está disponible en la Umbrel App Store!

Convierte tu Umbrel en una VPN de malla privada, o sea, puedes acceder de forma segura a tu Umbrel y a todos tus dispositivos desde cualquier lugar del mundo.

Piensa en Tailscale, pero sin una empresa intermediaria ni un servidor de control central en medio.

[TFTC @TFTC21]

Martti Malmi, one of Bitcoin's earliest developers, just released a new version of Nostr VPN, an open-source mesh VPN that replaces the entire trust model of traditional VPN services.

Traditional VPNs route all your traffic through a central server operated by a company you have to trust. They see your data. They require your email. They can log your activity. They can be subpoenaed, hacked, or shut down. Even modern mesh VPNs like Tailscale, which improved on this by sending data peer-to-peer, still require you to authenticate through a centralized coordination server using third-party accounts like Google or Microsoft.

Nostr VPN eliminates the central server entirely. Your identity is a Nostr keypair, a self-generated cryptographic key pair with no registration, no email, no third-party account. The underlying transport layer is FIPS (Free Internetworking Peering System), a self-organizing encrypted mesh network where nodes authenticate each other, route traffic for each other, and establish connections without any central authority or global topology knowledge. Each node's Nostr public key (npub) serves as its network address.

The architecture uses two layers of encryption: hop-by-hop encryption between peers and independent end-to-end encryption between mesh endpoints with periodic rekeying for forward secrecy. When direct connections fail due to NAT issues, the system falls back to Nostr-based multihop routing through other FIPS nodes rather than relying on company-operated relay servers. Peer discovery and NAT traversal happen through public Nostr relays using encrypted gift-wrapped messages.

The new release adds native desktop apps for macOS, Linux, and Windows, an Android app, Nostr-based multihop routing for when NAT holepunching fails, and improved network management. It supports UDP, TCP, Ethernet, Tor, and Bluetooth transports simultaneously on a single mesh.

This is what happens when you apply Bitcoin's design philosophy, permissionless, self-sovereign, no trusted third parties, to networking infrastructure. Built by one of the people who helped Satoshi build Bitcoin in 2009.

🚨 @Bitwarden serait en train de subir une refonte discrète et inquiétante, sans aucune communication officielle. 🤔

👉🏼Le fondateur/ancien PDG Michael Crandell a été remplacé en février par un nouveau CEO (Michael Sullivan) dont la spécialité est les fusions-acquisitions et le private equity (il a géré des deals à 1 milliard $). Le CFO a aussi été changé.
👉🏼Le slogan « Always free » a disparu du site en avril. Le plan gratuit existe encore… pour l’instant.
👉🏼Les valeurs de l’entreprise (GRIT) ont été modifiées : Inclusion et Transparency ont été supprimées au profit de Innovation et Trust. L’annonce ? Un simple edit silencieux d’un vieux billet de blog de 2022 qui se contredit maintenant.
👉🏼Tout est fait en douce : pas de communiqué, pas de blog post, juste des changements enterrés.

L’auteur [source en commentaire], qui utilisait Bitwarden cloud, a déjà tout migré sur Vaultwarden, la version self-hosted.
Il voit un schéma classique : on gagne la confiance, on crée la dépendance, puis on change les règles petit à petit en vue d’une vente ou d’une exit (probablement à un gros acteur).

Risque pour les utilisateurs : le modèle open source et le self-hosting pourraient être fragilisés à terme (même si ce n’est pas immédiat).
Il conseille de passer à une instance personnelle tant que c’est encore facile.

En résumé : Bitwarden passe d’un projet communautaire à une boîte gérée comme une startup PE prête à être vendue.
Le gratuit et la transparence ne sont plus des priorités affichées.
