Deploy a patient-controlled record sharing network where clinical data stays in each hospital's own systems and an on-chain consent and credential layer governs cross-facility access. No central database of patient records is ever created, yet an authorized doctor reaches history in seconds.
Enable cross-hospital access without centralizing a single sensitive record.
01.
Clinical records remain in each hospital's own systems. The chain carries only consent, credentials, and pointers, so no honeypot of centralized patient data is ever built.
02.
The DID and VC Ledger records patient and family consent as verifiable credentials, so a facility can prove it was authorized before any record is released.
03.
The Privacy and Compliance Guard enforces data-protection rules on every access, keeping disclosures within the legal boundaries for health information.
04.
The ZK Credentials Kit lets a provider prove eligibility, such as a treating relationship, without exposing unrelated patient details.
05.
In an emergency, a documented break-glass path grants a treating doctor time-boxed access with full logging, so urgent care is never blocked by process.
06.
Every access, consent grant, and emergency override is written to an immutable log, giving patients and regulators a full history of who viewed a record.
Follow an unconscious accident victim from admission through a consented emergency query to a safer treatment decision.

Cerulea decomposes cross-hospital sharing into modular contracts. Each layer enrolls, authorizes, retrieves, and audits access while clinical data never leaves its source system.
Patient-controlled record sharing is a horizontal capability. Here is how different actors in the care network put it to work.
Reach a patient's allergy and medication history in seconds during an emergency, avoiding contraindicated treatments while keeping every record in its home system.
Key Asset Types
Control who can see records and under what conditions, and review a complete history of every access, replacing lost physical files with a portable, consent-governed identity.
Key Asset Types
Audit cross-facility access against the consent that authorized it, confirming that data-protection rules held on every disclosure without inspecting each hospital's internal systems.
Key Asset Types
Whether you are bridging hospital information systems or capturing consent from a patient's own device, Cerulea routes both into one federated access layer.
For hospitals on legacy HIS and EMR platforms. Access requests are authorized on-chain and records are pulled from source through the API gateway without centralizing data.

Building a federated record network with on-chain consent, zero-knowledge eligibility checks, and a break-glass path from scratch requires specialised engineers and long inter-hospital integration cycles. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects multi-hospital interoperability benchmarks. Wiring each facility's HIS, building consent and credential logic, and shipping a compliant break-glass path for an average network takes a baseline of 10 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your consent and access rules into pre-audited WebAssembly binaries and provisions the federated consent ledger instantly.
