Privacy-focused AnChat challenges Signal with no-server model

A new encrypted messenger, AnChat Lite, has launched with a promise to remove centralized control from private communication. As detailed in a launch post on Hacker News, the platform distinguishes itself by running entirely on decentralized infrastructure and requiring no phone numbers or emails for signup. Instead, users authenticate via crypto wallets, ensuring zero identity data is collected during onboarding.

Escaping the Cloud

The core of AnChat’s pitch is independence from the traditional tech stack. While many privacy tools still rely on Amazon Web Services (AWS) or Google Cloud Platform (GCP), AnChat runs on the Orama Network. This is a distributed system of independent nodes connected via a WireGuard mesh, utilizing self-operated DNS.

Here is how the platform handles security and architecture:

  • Decentralized Routing: Messages do not pass through a central server. They route through independent nodes using a custom Go backend and Raft-based distributed SQL.
  • Metadata Shielding: Beyond standard end-to-end (E2E) encryption for content, AnChat uses the ANyONe Protocol (onion routing). This hides the metadata of who is talking to whom, a common vulnerability in other secure messengers.
  • Wallet-Based Auth: Identity is tied to a crypto wallet rather than a SIM card or email address, removing the link to real-world identity documents.

The Privacy Spectrum

AnChat is positioning itself against the current market leaders by attacking their infrastructure dependencies. The creators note that Signal, while secure, routes traffic through centralized servers and mandates a phone number. Matrix offers a federated model, but users are still dependent on specific servers.

This launch targets users who view server centralization, even by a benevolent entity, as a single point of failure or control. By removing the central authority, AnChat aims to make censorship or data seizures significantly harder.

Availability and Limitations

The app is currently in closed beta. It is available on iOS via TestFlight and on Android through Google Play or direct APK download.

However, the developers were transparent about current limitations. As a beta product, users should expect bugs and a small initial user base. Perhaps more significantly, the reliance on wallet-based authentication creates friction for mainstream users who aren’t “crypto-native.” The team acknowledges this onboarding hurdle is a priority for future updates.

This is a significant development for privacy advocates who worry about metadata surveillance. While Signal protects message content, hiding the connections between users usually requires complex tools like Tor. AnChat attempts to bake that anonymity directly into the mobile messaging layer.
