What Northstar Protocol approved
A patient-facing care companion with verified Telegram sign-in, simple email accounts, care notes, chat history, and a Walrus Memory save-and-recall workflow.
A patient-facing care companion with verified Telegram sign-in, simple email accounts, care notes, chat history, and a Walrus Memory save-and-recall workflow. The frontend uses React/Vite; the API uses Express with PostgreSQL for hosting or SQLite through Node's built-in node:sqlite for local development. Gemini supplies chat responses. Original generated artwork lives in src/assets/. This is a working hackathon implementation for synthetic patient data. Live Gemini responses and mainnet Walrus writes require your own provider credentials and end-to-end verification. Configuring the code does not itself create a blob or prove hackathon eligibility.

Check it without Atesta
The NFT points at the public credential document (NEP-177 reference) and carries its Base64 SHA-256 (reference_hash). Fetch the document, hash its exact bytes, and compare with both the reference hash and the digest stored on NEAR. No Atesta account or database is involved.

What this does and does not prove
It proves that Northstar Protocol approved this exact claim on 13 November 2026 and that the record has not been altered since. It does not prove that every detail is true, or that you should trust Northstar Protocol; Atesta has reviewed the organisation, which is not the same as vouching for each claim.
