A community-owned DataDAO for ethical contribution and activation of supplement usage data.
Powered by OpenFHIRChain — a modular framework for bringing FHIR medical standards to the blockchain.
NutriDAO is a decentralized, user-owned data collective focused on the voluntary contribution and ethical activation of supplement usage data.
Participants contribute their data to a Data Liquidity Pool (DLP) — a smart contract that tokenizes their contributions and ensures consent-based access, control, and rewards.
This data can be used to train AI models and power personalized wellness applications — always under user consent.
NutriDAO rewards participation and gives contributors a voice in how their data is accessed, used, and monetized.
OpenFHIRChain is an open-source framework that brings a subset of the HL7 FHIR healthcare data standard to Web3.
It provides modular smart contracts and IPFS integration to store and manage FHIR-compliant resources on-chain.
NutriDAO is the first real-world use case of OpenFHIRChain, applying its infrastructure to the health and wellness data space. OpenFHIRChain is extensible and can support additional FHIR resources in future DataDAOs.
NutriDAO is being developed as part of the Vana Academy, a 9-week accelerator designed to launch user-owned DataDAOs.
We are progressing through the following phases:
-
Bootcamp & Discovery (Weeks 1–3)
Understanding the Vana ecosystem, architecture, token standards, and consent-driven data models. -
Building Phase (Weeks 4–5)
Finalizing our FHIR data subset, designing smart contracts, and refining the token and governance model. -
GTM Sprint (Weeks 6–8)
Launching the MVP, defining tokenomics, and preparing for adoption and integration. -
Demo Day (Week 9)
Presenting NutriDAO to investors, builders, and the broader Vana ecosystem.
- 🧠 Empower individuals to take control of their nutrition data
- 🔗 Enable interoperable and privacy-preserving health data sharing
- 🤖 Support the development of human-aligned, AI-driven wellness tools
- 💡 Democratize access to high-quality health data insights
- Voluntary contribution of anonymized supplement usage data
- Training of personalized AI models for health and wellness
- Empowering researchers and startups with consent-based health data
- Building dashboards and analytics based on verifiable FHIR resources
We are currently evaluating key architectural components, including smart contract logic, data storage models, and governance frameworks.
Our goal is to align technical choices with the principles of ethical data ownership and interoperability through OpenFHIRChain and in alignment with the Vana ecosystem.
We welcome collaborators from the health, Web3, and AI ecosystems.
