Hmm, if you had a model with 128-bit words that skipped floating point, and left out the sneaky stuff that makes some people distrust Intel and AMD processors, you'd have an almost ideal chip for Ethereum nodes. (Make it 256-bit words and it'd really be ideal.)

Not that that's a huge market at this point, but apparently there's a lot of Fortune 500 interest so maybe that'll change by the time you're in production.

Something I don't see mentioned on your site is the rest of the hardware. Specifically is Mill intended to more of a co-processor with computing work handed over to it, or is it standalone in a system. If standalone what is the situation over bootup (eg UEFI or equivalent) and controllers like PCIe, USB, storage (NVME, SATA etc), NICs etc.

AFAIK, It's intended as a general purpose processor.

And when you show a reference design for a smart phone with provably strong security capabilities its going to get very real indeed. Kudos for continuing the push toward real parts.
