Bitcoin Witness — Product Preview

PRODUCT PREVIEW

See it work.

The demo below is the application the user sees after installation, in a full desktop environment. Click through the menus and options. Approximately 90% of the demo is based on real code and real appliance output. For the purposes of this demo and simple practicality only some screens had to be adjusted.

The demo is a walk-through of the real air-gapped interface. All outputs are based on public test vectors.

Do not use them in your real workflows.

We are actively testing the code and are aware of some inconsistencies. If you notice something wrong or just have any suggestions, email us at the address below, and thank you for your interest!
