The Cascade Protocol is a developer-first framework for building secure, interoperable health applications where patients own and control their data.
Built for the future of health data: secure, portable, and truly owned by patients.
Health records stored in personal data pods with WebID-based access control. Patients decide who sees their data and for how long.
Built on W3C Linked Data standards (RDF/OWL) and aligned with FHIR, SNOMED CT, and LOINC for seamless healthcare system integration.
ChaCha20-Poly1305 encryption protects all stored data. Keys are secured in the device keychain, never transmitted.
Designed for AI agents to securely access and process health data with explicit user consent and comprehensive audit trails.
Swift SDK abstracts the complexity of compliance, encryption, and semantic data modeling. Focus on your app, not infrastructure.
HIPAA-ready architecture with built-in audit logging, consent management, and data provenance tracking using W3C PROV-O.
The Cascade Protocol creates a secure, portable health record that follows patients across apps and providers.
Apps built on Cascade Protocol capture health data using device sensors, manual entry, or medical device imports.
Data is encrypted and stored locally in a Solid-compatible personal data pod owned entirely by the patient.
Patients grant granular, time-limited access to healthcare providers, researchers, or AI agents as needed.
Linked Data format enables any compliant system to read and process the data without proprietary lock-in.
The Cascade Protocol leverages proven W3C and healthcare standards for maximum interoperability.
Decentralized data pods with WebID authentication
W3C semantic web standards for linked data
W3C provenance ontology for audit trails
HL7 healthcare interoperability standard
Clinical terminology mapping
Laboratory observation identifiers
See the protocol in action with real-world health applications.
The first application built entirely on the Cascade Protocol. POTS Check is an at-home screening tool for Postural Orthostatic Tachycardia Syndrome (POTS) using Apple Watch heart rate monitoring and the NASA Lean Test protocol.
All test results are stored locally in an encrypted personal data pod, giving users complete ownership of their health screening history.
Join us in creating the future of patient-owned health data. The SDK and documentation are coming soon for developers.
