Digital Identity, Zero-Knowledge Proofs and Post-Quantum Cryptography for Trusted Global Financial Ecosystems
Year: 2026
Type: reference-entry
Abstract: This research book develops an integrated architecture for trusted global financial ecosystems in which digital identity, selective disclosure through zero-knowledge proofs, and post-quantum cryptography operate as mutually reinforcing trust layers. The central problem is not merely authentication; it is the need to establish who or what may participate in a financial process, disclose only the attributes necessary for a decision, preserve confidentiality across institutions and jurisdictions, and maintain cryptographic assurance against long-horizon threats. The manuscript combines identity governance, cryptographic protocol design, causal and statistical risk reasoning, trustworthy machine learning, scalable data engineering, reproducibility, audit evidence and policy oversight. It treats zero-knowledge proofs as a privacy-preserving design layer within a broader post-quantum transition strategy, while distinguishing proof validity from identity governance and transaction-risk inference. A five-chapter framework progresses from foundations and research design to statistical modelling, machine-learning trustworthiness, scalable cryptographic data lifecycles and cross-border governance. The book also proposes an invention-oriented architecture for policy-bound, proof-carrying financial credentials with crypto-agile post-quantum migration. Across South Asia, Europe, Africa and the Americas, the framework emphasizes interoperability, proportional disclosure, verifiable assurance, model accountability, operational resilience and institutionally credible governance.
