# Pillar One: Spine

### **Spine – Encrypted Health Vault**

Imagine a decentralized “health passport” that travels with you globally.

* **Zero-Knowledge Proofs**: Share medical results without exposing identities.
* **Patient-Contained Keys**: You control who accesses your MRI scans or vaccination records.
* **Interchain Portability**: Seamlessly sync data across hospitals, insurers, and wearables.

On the HealthLink platform, patients have full control over their health data, ensuring data integrity and security through blockchain, enabling easy cross-institutional sharing.
