"answer": "Each prism registers on the ocean, a ledger keyed by hardware-attested host, only by spending crystal, a single-use attestation key fused into a physical chip and revoked once used. The k-th prism anchored to one host or rack must spend k crystal, so a thousand clones on one rack cost about 500,500 crystal. Spreading out means buying a thousand distinct attested machines, since rented cloud hosts report the same rack and collide. It breaks if chip keys can be extracted or a vendor mints them in bulk.",
