Help spread awareness for build reproducibility
Please help us spread the word discussing build reproducibility with Open Ledger Micro via their Twitter!
Do your own research!
Try out searching for "lost bitcoins", "stole my money" or "scammers" together with the wallet's name, even if you think the wallet is generally trustworthy. For all the bigger wallets you will find accusations. Make sure you understand why they were made and if you are comfortable with the provider's reaction.
The Analysis ¶
The Raspberry Pi Zero is a $5.00 computer with no WiFi or Bluetooth and can be configured to emulate Ethernet over USB. The application written in Go and Angular, serves a RESTful API to be consumed with the integrated Angular application.
The point of hardware wallets is that they hold encrypted private keys, never expose the private keys, and operate in an offline environment. We are using a Raspberry Pi Zero because it has neither WiFi or Bluetooth which makes it much more difficult to compromise.
Once configured, software like Bonjour on a host machine will allow the Raspberry Pi Zero to be accessed by its hostname. For example, http://raspberrypi.local would show the Angular web application.
Sensitive information such as private keys are encrypted on the Raspberry Pi and are never exposed through HTTP. Transactions are created and signed directly on the device and returned to the Angular application.
This is a do-it-yourself project.
This project is not meant for non-technical end users.
As part of our Methodology, we ask:Is the product meant to be ready for use "out of the box"? If not, we tag it DIY
Many hardware wallet projects aim to be as transparent as possible by using only off-the-shelf hardware with an open design and open code. If the product reviewed is not available in an assembled form - if the user has to source his own hardware to then maybe solder and compile software to install on the device it falls into this category.
