Overview
Prescription Tokens is a blockchain-based demo illustrating secure prescription data capture and transfer using tokens on the BSV blockchain. It models a workflow where doctors create prescription tokens, which are passed to patients and pharmacies to verify and dispense medications securely.
Features
Tokenization of prescriptions for secure transfer and redemption
Immutable record of prescription origination anchored on BSV
Clear roles: Doctor (creator), Patient (holder), Pharmacy (redeemer)
Simple web interface to interact with tokens
Demo-level codebase for extension and integration
System Architecture
Frontend (TypeScript, React)
Provides a web UI for creating, sending, and redeeming prescription tokens
Displays token status and related transaction info
Backend (Node.js, Express)
Manages token lifecycle, prescription metadata, and blockchain interactions
Interfaces with BSV network to anchor transactions
RESTful APIs for frontend communication
Quick Start
Prerequisites
Node.js and npm installed
Basic familiarity with BSV blockchain concepts
To Run
npm i
npm run build
lars startVisit http://localhost:3000 on your browser to interact with the demo.
Usage Guide
Prescription Token Workflow
Doctor: Create a prescription token and assign to a patient
Patient: Receive and hold the token
Pharmacy: Redeem the token to verify and dispense medication
Tokens map prescription data immutably on the BSV blockchain, enabling secure tracking and audit.
API Endpoints
APIs to create, transfer and redeem tokens
Endpoints to query token status and transaction proofs
(Specific endpoints are defined in the repo backend code)
Security Features
Blockchain-anchored token creation provides tamper-proof provenance
Tokens ensure strict control over prescription usage and one-time redemption
Transparent audit trail with cryptographic verification
Testing & Validation
Unit and integration tests for token lifecycle and blockchain anchoring
Manual UI testing for prescription creation and redemption flows
Troubleshooting & Support
Check logs for API and blockchain transaction errors
Verify BSV node or network connectivity
