Google is apparently working on a new operating system, called Fuchsia, that won’t be based on Android. The company isn’t giving any specifics about the OS other than the information found on a page that surfaced on GitHub, the code-sharing website.

According to the GitHub page, the operating system unlike every other Google OS won’t even be built on the Linux kernel.

Instead, it will be built on Magenta, a microkernel based project called “LittleKernel” that is used in embedded systems. Android Police, which was the first to uncover the GitHub page, says Magenta is designed to scale much better and can work on embedded devices, smartphones, and desktop computers.

The two developers working on the project — Christopher Anderson and Brian Swetland — are experts in embedded systems. Anderson, a senior systems engineer for embedded devices, previously worked on Android and on robotics for Google. Swetland, a senior staff engineer, worked for Android Inc., before it was acquired by Google in 2005.

Because the Internet of Things (IoT) is based upon embedded devices and embedded hardware, it’s logical to infer that this new OS is intended for IoT. However, the company already has Brillo, an operating system that was announced at the 2015 Google I/O conference. Brillo is based on Android and supports Wi-Fi and Bluetooth Low Energy.

Google also has Weave, a cross platform common language that lets Brillo devices, phones, and the internet all talk to each other.

It’s unclear how Fuchsia will fit in with platforms like Brillo and Weave. But because Google hasn’t made any formal announcement about the OS, speculation is all over the place. Some believe that Fuchsia will be used solely for IoT, similar to Samsung’s Tizen operating system. Others are hinting that the company may be planning to use Fuchsia to replace Chrome OS and Android.

Of course, Google is likely putting so much effort into the IoT space because of the projected growth in this area. Research firm Strategy Analytics predicts that IoT will be a $150 billion market this year and will grow to $550 billion in 2025.
