Imagine this in the distant future. You buy a new bitcoin signing device which is open source (hardware & software). You stop by @Bitcoin Park and pay 100 sats to use their chip verifier. It checks that your hardware wallet chips match the open source spec.
Sounds like science fiction, but check out this new talk by Bunnie Huang where he presents a technique for "seeing through silicon" - inspecting chips which are on circuitboards from the backside without removal.
"How important is the transparency aspect of this, and how far do we, as a country, want to go with our Bitcoin holdings? If we look at the El Salvador model, they have a page that shows exactly how much Bitcoin they hold at all times."
