- Attendees tap their NFC tags or wristbands on an RC522 reader connected to an ESP8266 WiFi module.
- The 5G-integrated backend, deployed on an Edge network, instantly notifies mentors with:
- User’s name and seating location.
- Social handle for direct communication.
- Mentors provide help, and attendees tap the mentor’s ARX Halo NFC badge to:
- Generate a Proof of Help, signed with the mentor’s Ethereum address.
- The signature and request details are attested using the Sign Protocol on the blockchain, creating a tamper-proof record.
- Attendees rate mentors post-assistance.
- Ratings are aggregated on Edge-deployed MongoDB servers, calculating a Reputation Score based on non-zero ratings, rewarding mentors for their efforts.
- RC522 RFID Reader: Reads NFC tags and badges.
- ESP8266 WiFi Module: Transmits data to the backend over a 5G-ready network for low-latency communication.
- ARX Halo NFC Chips: Securely embed Ethereum addresses for signature generation.
- 5G Integration: Ensures seamless data transmission even in high-density or remote areas.
- Edge Computing: Reduces latency by processing help requests and ratings closer to the event location, enabling real-time responsiveness.
- Backend: Node.js with MongoDB for decentralized data management.
- Blockchain: Sign Protocol for on-chain attestation of "Proof of Help."
- Frontend: JavaScript and HTML for user interaction.
- Low-Latency Communication: Edge computing and 5G ensure real-time help request handling, even in large-scale events.
- Scalable and Affordable: NFC tags and wristbands are cost-effective and widely adopted at events.
- Decentralized Validation: Blockchain attestation provides verifiable records of interactions.
- Reputation System: Mentor performance is transparently tracked and incentivized through ratings.
- Resilient Connectivity: 5G ensures uninterrupted operation in urban or remote areas.
NFCare harnesses the power of 5G and Edge Computing to deliver a scalable, verifiable, and real-time "Proof of Help" system, redefining how collaboration is tracked and rewarded.
