Frequently asked questions

What is a Light Node?
A light node is a lightweight, less resource-intensive Ethereum node that instead of downloading every block, downloads only the block headers containing a summary of the information within the blocks. If a light node needs additional information contained in a block, it must request it from a full node. These are the “peers” in your ethOS light node app.

Currently, ethOS’s Geth light node is unavailable due to technical changes with Ethereum’s upgrade to Proof of Stake, and will be back once the Geth team completes their updates.

While this is the case, ethOS is adding the Helios and Nimbus light client implementations, providing verifiably trustless local RPCs to maximize trustless options on ethOS.
How do I use XMTP Chat?
Just open the SMS App and wait for a few seconds, then a popup from the ethOS system-wallet should show the data you need to sign to login into XMTP and setup the messenger.
What mobile devices can I load ethOS onto?
ethOS can be installed onto an OEM Unlocked Google Pixel 3, 3XL, or 5a, via our easy web installer. ethOS cannot be installed on OEM locked devices.

While more devices will be supported in the future, the current lineup allows for faster development against a focused set of hardware, while balancing affordability for individuals seeking to try ethOS (Pixel 3 & 3XL), and the capability that newer hardware brings (Pixel 5a).

Our Discord has some helpful links for individuals looking to purchase a used Pixel.
Can I run ethOS on an emulator?
In addition to physical devices, ethOS can also be run on emulators. Just follow our detailed instructions on how to set it up and reach out if you need any help.
Who is building ethOS?
ethOS is an organic, open source, community-led project in development by individuals across the globe. You can find us in the ethOS discord, or on GitHub.
How do I get involved?
Join the party. Pick up a used and OEM unlocked Pixel 3, 3XL, or 5a, install ethOS, and share your feedback in the discord! You will have a direct and meaningful impact on the development path of the OS. We love testers.

If you’re looking to contribute in other ways (code, design, marketing, copy, legal, etc), introduce yourself in the discord, share where you think you could help, and spend some time with us there. Because this project is distributed, individuals that have helped build ethOS over time tend to excel at providing their own initiative for moving through tasks, and proactively find where they can help with the next ones. If you believe in the mission of ethOS, please come say hello!
