Quantum-Secure Data Fusion System and Method for Continuous Sovereign Reserve Peg Compliance, Secure Settlement, and Sovereign Treasury Reporting in Reserve-Backed Digital Currency Infrastructure — Defensive Publication

[TECHNICAL DISCLOSURE — DEFENSIVE PUBLICATION] This disclosure is published to establish prior art under 35 U.S.C. § 102 and to prevent third-party patenting of the described architecture. Publication date: April 24, 2026. Corresponding TDCommons defensive publication: Article ID 11238, April 24, 2026. This disclosure describes a quantum-secure data fusion system and method for continuous sovereign reserve peg compliance verification, secure settlement finality, and machine-readable sovereign treasury reporting in reserve-backed digital currency infrastructure. The architecture comprises four integrated modules sharing a common quantum-secure cryptographic foundation: a Data Fusion Compliance Engine, a Compliance Monitor with automated halt and sovereign alert protocol, a Settlement Bridge, and a Sovereign Treasury Reporting Interface. All cryptographic operations implement lattice-based key encapsulation (NIST FIPS 203, ML-KEM) and lattice-based digital signatures (NIST FIPS 204, ML-DSA) as hardware primitives within tamper-resistant key storage modules. The system is deployable as a discrete, separable compliance module within any conforming reserve-backed digital currency infrastructure.
