Identity protocols can support adventure park admissions by issuing verifiable credentials (VCs) to visitors, proving eligibility (e.g., age, height, ticket type) via decentralized identifiers (DIDs). Smart contracts track ride access, linking VCs to IoT-enabled wristbands for secure, contactless entry. Zero-knowledge proofs validate credentials without exposing personal data, while dynamic pricing (e.g., group discounts) and real-time capacity updates optimize park operations and visitor flow.
