I'm using an STSAFE chip - the same IC they use in StarLink terminals. Essentially the digital equivalent of a holographic barcode. I have some other protections too. e.g. Random 128-bit per-device IDs / product-keys. iMessage uses this strategy.

Maybe I'll write an article about that.

Sounds like that'll be a great read.

This is (literally) none of my business, but would you consider a cut down or basic open source version (hardware and software, with open software running in the proper hardware). Yes it'll be cloned by factories, and yes it will cut into sales no matter what proponents claim. (And yes it's probably more work than I imagine it is).

But also yes, it'll be genuine open hardware and might out live your interest in the project.

How do you verify the ID? In the software? What if the software is hacked? I'm curious how this can be safe.

Please do! Trying to imagine how this works.

Yes, please do!

Please!

Please do, that'd be very interesting. I imagine it's doable to use random per-device I'd when you're hand-flashing, but probably harder on a huge production run.
