Application of Digital Currency in Secure Areas

Product Advantage: Building a Transparent and Efficient Digital Payment Ecosystem

In secure zones (e.g., customs checkpoints, data centers, airport airside areas), traditional payment methods are inefficient due to complex security, authentication, and clearance procedures. Our digital currency solution enables a closed-loop, fully auditable payment network with identity binding, access control, and traceability, meeting the dual requirements of high security and controllability.

Key Technical Features

1. Permissioned Wallet Architecture
Powered by zero-knowledge proof, verifiable credentials (VC), and decentralized identity (DID), the wallet system ensures only authorized users can access and transact within designated secure areas.

2. On-Chain Auditing and Tamper Resistance
Every transaction is logged immutably on-chain, ensuring transparency and allowing regulators or auditors to track fund flows in real time.

3. Offline-Resilient Architecture
By leveraging edge computing and ledger replicas, transactions can be processed locally during connectivity disruptions and automatically synchronized afterward.

Typical Workflow

1. Pre-registration and Wallet Issuance
Users are pre-registered via identity verification systems. Wallets are issued with role-based privileges.

2. Access Mapping and Wallet Binding
Each wallet is mapped to a specific user’s identity and area-specific access rights, enforcing transaction limits, types, and rules.

3. Intra-Zone Transactions
All payments are executed within the localized blockchain environment, independent of external financial systems, and settled in real time with automated smart contract enforcement.

4. Audit & Risk Monitoring
The system includes behavioral anomaly detection and scoring, alerting admins to suspicious activities, and generates detailed audit reports.
