Zero-Knowledge Proof Systems for Digital Identity Infrastructure

Digital identity usually fails at the same point: verification requires disclosure.

The ZKP idea

Zero-knowledge proofs allow a user to prove a statement is true (e.g., age eligibility, membership, residency) without revealing the underlying data.

Why it matters for infrastructure

Identity becomes safer when:

• systems collect less data
• breaches expose less value
• verification is cryptographic and portable

Deployment reality

To ship ZKP systems, we care about:

• proving time at scale
• verifier cost
• key management and recovery
• interoperability with governments and enterprises

Sizzle Asia Labs explores ZKP-based architectures as a core primitive for future digital identity systems.
