Third-party notices

Origo was derived from the Blockstream Jade firmware, distributed under the MIT License. The original license and copyright notice are retained in LICENSE.

The following third-party components remain subject to their own notices:

  • libwally-core, copyright Jon Griffiths (Blockstream), is included as a pinned Git submodule and distributed under its BSD-MIT license. See components/libwally-core/upstream/LICENSE and the notices in its source.
  • QRCode, copyright Richard Moore, is distributed under the MIT License. Its license is retained in main/qrcode.c and main/qrcode.h. It is Moore's port of Project Nayuki's QR Code generator, taken from Blockstream Jade's main/qrcode.c and main/qrcode.h at commit 4765740e3aadc096800f42a3cccbe2d5a54b582f (SHA256 e65cb6f8359cbd68d6388ffce6d44fda51cad849cbf6afdb12d2dc36d7fdf50e and 25b3eb0a638635ac0590bc263bd86729586cd7f4ffa9a496e1dfce675eedf22f). Jade's later changes to those files touch only its icon helpers, which Origo does not carry. "The QR encoder" in docs/verify.md lists what Origo changed.
  • DefaultFont font data is inherited from the Blockstream Jade source distribution, byte for byte Jade's main/fonts/DefaultFont.c at the same commit (SHA256 4786af48b658f7e44359236665830c5e488489e2bda35d2eebf914c80a7c5099). Its source comments and the repository MIT license are retained.
  • UbuntuRegular16 and UbuntuMedium16 font data are generated by tools/make_font.py from Ubuntu Regular and Ubuntu Medium, copyright 2010-2011 Canonical Ltd., taken from github.com/google/fonts (Ubuntu-Regular.ttf, SHA256 3128df86a31805618436d0ae5651ba4285d0c9de0a39057d025f64ee33bceb64; Ubuntu-Medium.ttf, SHA256 3cd952b8b52581e48a8fa95b31c8829c2baa41b635042a69587d57f98092961e), and distributed under the Ubuntu Font Licence 1.0, retained in main/fonts/UFL.txt.
