I built a simple tool to check if Bitcoin is actually active (no APIs, real hardware)

Hey Indie Hackers 👋

• No public APIs

• No third-party services

• Data comes from a physical ESP32 device connected to the Bitcoin network

• The tool just returns a clear yes / no indicator, nothing more

The goal was:

• no jargon

• no charts overload

• something understandable in 5 seconds

This is part of a larger SaaS, but this page is 100% free and public.

I’d love feedback on:

• usefulness of such a “binary” indicator

• ideas for a V2 (network stability, congestion, etc.)

• whether you’d trust hardware-based data more than APIs

Thanks 🙌
Christophe
