Bitcoin

An interesting application for the CYD ESP32

You can flash it with Bitcoin mining firmware, giving it a slim chance of discovering blocks or connecting to nodes.

According to ChatGPT, don’t expect to actually hit the jackpot; this is merely a recreational novelty. The probability of successfully mining a block is roughly one in several hundred trillion—effectively zero.

However, it serves as a decent tool for learning about Bitcoin, and it makes for a nice desktop ornament.

Ideal for:

Learning the Stratum protocol

Learning about SHA256

Understanding how mining pools work

Learning about the ESP32 microcontroller

A DIY desktop gadget project

Project Repository: NMMiner

Other Notes

I noticed that using this project requires registration and the generation of certain credentials.

That feels a bit too complicated for my taste, so I couldn’t be bothered to tinker with it—I’m not particularly interested anyway.

I’m simply documenting these CYD ESP32 projects here so that, should I ever have a need for them in the future, I can quickly locate this information and give them a try.
