The idea is to get rid of both hardware and software backdoors, install all necessary tools on a Pi 4 and sell it as a plug-and-play device. Including shipping cost the total estimated price is 200 USD.
If you have your [Raspberry Pi 4](https://www.raspberrypi.com/products/raspberry-pi-4-model-b) or [Pine64 ROCKPro64](https://pine64.com/product/rockpro64-4gb-single-board-computer) already you can just follow the guide.

* [Raspberry Pi 4 model b](https://www.raspberrypi.com/products/raspberry-pi-4-model-b) with 4GB of RAM device will be used in order to avoid Intel ME and AMD PSP.
* If you require AES hardware, which most users will not, then make sure you use a Pine64 board.
* [Devuan GNU+Linux](https://arm-files.devuan.org/RaspberryPi%20Latest%20Builds) will be installed, a fork of Debian without [systemd](https://ebin.city/~werwolf/posts/systemd-sucks), but [sysvinit](https://www.devuan.org/os/init-freedom) or openrc, runit, sinit and 66-devuan.
* For private transaction and communication [Hush](https://hush.land) cryptocurrency and [HushChat](https://git.hush.is/hush/hushchat) were chosen to fulfill this task.
* To start using HushChat right away a privkey for 0.5 HUSH will be provided.
