Bru 是一款开源的 Android 应用加网页客户端，让你能在浏览器中读取和发送手机短信，使用 Rust、Kotlin 和 Iroh（浏览器端 WASM）实现点对点连接，无需账号且注重隐私。

Iroh explores how to build permissionless global content discovery for its P2P networking stack, studying BitTorrent's Mainline DHT as a proven model while arguing its own BLAKE3-based iroh-blobs verified streaming protocol is superior to BitTorrent's transfer protocol.

Iroh's managed relays are now authenticated by default, requiring API-key-issued capability tokens so only authorized endpoints can use them, preventing relay abuse and traffic hijacking.

The article demonstrates how to build a smart fan using an ESP32 microcontroller and the iroh networking library, enabling peer-to-peer control without a cloud service.
