Tamarin with ROFL: Enabling Privacy-First Healthcare Collaboration with Oasis Technology

Healthcare data is among the most sensitive in the world, yet sharing it securely between providers, researchers, and institutions remains incredibly difficult. Privacy concerns, regulatory constraints, and technological silos all stand in the way of better outcomes. Tamarin Health is working to change that through its privacy-preserving protocol, Nectar. And now, with support from the Oasis Foundation, they’re integrating Oasis’s ROFL framework to power secure, policy-controlled data collaboration across institutions. The Challenge: Data Sharing Without Compromising Privacy In healthcare, collaboration is essential—patients often see multiple providers, and researchers rely on access to large datasets. But centralized data exchange systems pose risks: → Privacy leaks from misconfigured or compromised servers. → Compliance burdens with HIPAA and similar regulations. → Limited interoperability between different health networks. What’s needed is a model where data can be used collaboratively without leaving the control of the original institution. The Tech: Oasis ROFL and Trusted Execution Environments Oasis’s ROFL (Runtime Off-Chain Logic) enables secure off-chain computation using Trusted Execution Environments (TEEs). This means: → Sensitive queries can run on encrypted data. → Results are cryptographically verified via remote attestation. → No need to expose or move raw patient data across networks. It’s a powerful model for industries like healthcare, where verifiable processing without data exposure is the gold standard. Tamarin Health's Integration: Nectar Meets ROFL With a grant from the Oasis Foundation, Tamarin Health is now integrating ROFL into Nectar, its protocol for secure healthcare data collaboration. The result: → Providers can analyze and share insights without giving up data custody. → All access and computation occur in privacy-preserving environments. → Regulatory compliance is enforced through smart, auditable access policies. This reshapes how health institutions can work together—turning data silos into secure, collaborative networks. Why It Matters for Developers If you're building in regulated, privacy-first verticals like healthcare, this is a practical demonstration of how to: → Use off-chain secure compute to enable policy-bound collaboration. → Leverage TEEs to enforce trust without exposing raw data. → Build with compliance and verifiability from day one. Whether you're developing healthcare apps, research platforms, or multi-party data systems, ROFL and Tamarin's integration offers a path forward.

Tamarin with ROFL: Enabling Privacy-First Healthcare Collaboration with Oasis Technology

Healthcare data is among the most sensitive in the world, yet sharing it securely between providers, researchers, and institutions remains incredibly difficult. Privacy concerns, regulatory constraints, and technological silos all stand in the way of better outcomes.

Tamarin Health is working to change that through its privacy-preserving protocol, Nectar. And now, with support from the Oasis Foundation, they’re integrating Oasis’s ROFL framework to power secure, policy-controlled data collaboration across institutions.

The Challenge: Data Sharing Without Compromising Privacy

In healthcare, collaboration is essential—patients often see multiple providers, and researchers rely on access to large datasets. But centralized data exchange systems pose risks:

→ Privacy leaks from misconfigured or compromised servers.
→ Compliance burdens with HIPAA and similar regulations.
→ Limited interoperability between different health networks.

What’s needed is a model where data can be used collaboratively without leaving the control of the original institution.

The Tech: Oasis ROFL and Trusted Execution Environments

Oasis’s ROFL (Runtime Off-Chain Logic) enables secure off-chain computation using Trusted Execution Environments (TEEs). This means:

→ Sensitive queries can run on encrypted data.
→ Results are cryptographically verified via remote attestation.
→ No need to expose or move raw patient data across networks.

It’s a powerful model for industries like healthcare, where verifiable processing without data exposure is the gold standard.

Tamarin Health's Integration: Nectar Meets ROFL

With a grant from the Oasis Foundation, Tamarin Health is now integrating ROFL into Nectar, its protocol for secure healthcare data collaboration. The result:

→ Providers can analyze and share insights without giving up data custody.
→ All access and computation occur in privacy-preserving environments.
→ Regulatory compliance is enforced through smart, auditable access policies.

This reshapes how health institutions can work together—turning data silos into secure, collaborative networks.

Why It Matters for Developers

If you're building in regulated, privacy-first verticals like healthcare, this is a practical demonstration of how to:

→ Leverage TEEs to enforce trust without exposing raw data.
→ Build with compliance and verifiability from day one.
