What this is

SILICON-X402 names a payment approval scheme locked to a chip's own physical fingerprint, using a Physically Unclonable Function (PUF). Every chip has microscopic manufacturing variations that make it produce a unique, unclonable response to a given input. The idea is to root two signatures in that silicon randomness, so approval is tied to one specific physical chip rather than a key that could be copied.

This is the concept as the page has always stated it. There is no live endpoint or working demonstration of it here.
