SILICON-X402
Payment approval locked to a chip's own physical fingerprint, using two signatures rooted in silicon randomness.
Protocol · roadmap
SILICON-X402 is on the NanoVerse protocol roadmap
The five primitives and ten verticals elsewhere in NanoVerse are live today. This handshake protocol is not deployed at a public host yet. Treat the route below as a spec, not a live API.

Target shape: submit a signed request and get back a PUF-anchored attestation.
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.
