Zero-Knowledge Proofs: Sovereignty Cryptographic Primitive

Zero-knowledge proofs evergreen hub. 4 families mapped (Scaling, Privacy, Identity, CBDC). From Goldwasser 1985 to 2026 STARK hardware. Cache256 sovereignty doctrine applied. Tornado Cash + AMLR Article 79 + Worldcoin counter-example. Math is neutral. Deployment is not.

Tools, Not Declarations

Zero-knowledge proofs are the only technical primitive that expresses the third position of Sum in machine: proving without being declared. Cache256 maps the four families (scaling, privacy, identity, central bank), reads Worldcoin against the grain, and asks four questions.
