There is currently a phishing email going around that's pretending to come from us.
Please do not follow the instructions in the email!
We are currently investigating.
⚠️ ACHTUNG: BITBOX-PHISHING
Aktuell kursiert eine Phishing-Mail, die vorgibt, von BitBox zu stammen und vor einem angeblich fehlerhaften Random Number Generator (RNG) warnt.
Diese E-Mail ist FAKE.

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.

🇪🇺 EU prepares to issue standardized guidance for the surveillance of "self-hosted wallets"
The EU Anti-Money Laundering Authority (AMLA) is preparing to issue guidance for the technical requirements to surveil transactions between "self-hosted wallets" and accounts held with Crypto Asset Service Providers (CASPs).
The guidance will lay out what steps CASPs must take to identify the owner of a self-custodial address as required by the EU's Transfer of Funds regulation, in effect since December 2024.
The guidance will be issued by July 2027.

We can keep using barbaric manual shitcoins that rely on the authority of violence, causing endless conflict & politics.
Or we could upgrade to a peaceful software solution that runs on electricity and cannot be corrupted by politics or violence.
That's why bitcoin is worth it
