These things should be manufactured to be IRIS-compatible. IRIS is the "Infra-Red, In Situ" technique which lets you image the silicon of a chip through the packaging to verify that you don't have a counterfeit. https://arxiv.org/pdf/2303.07406 Like, for example, the Boachip-1x MCU. https://www.cnx-software.com/2026/03/04/dabao-board-features...

Ah yes. The Precursor is real now, you can read more at https://precursor.dev. As a baseline it can function as a password/authentication token manager, but as another user mentioned we're adding messaging features now. Another thing I'm working on is IRIS, a non-destructive method for inspecting silicon chips after mounting on a circuit board: https://arxiv.org/abs/2303.07406 It's part of a long yak-shaving arc to make the Precursor more accessible by migrating from an FPGA-based system to an ASIC.
