Crimson: Decentralized Blood & Organ Donation Platform

Deployed Link - https://crimson-alpha.vercel.app/

Overview

Crimson is a blockchain-powered platform revolutionizing blood and organ donation. It combines AI for document analysis with smart contracts for secure, transparent, and traceable transactions. Crimson bridges hospitals, NGOs, and donors into a seamless ecosystem — ensuring every donation is recorded, incentives are fairly distributed, and fraudulent activities are proactively flagged.

Problems Solved

• Lack of Transparency: Blockchain records all transactions, making donation cycles verifiable and immutable.

• Document Verification Delays: AI-powered OCR swiftly processes health documents uploaded to IPFS, streamlining eligibility checks.

• Organ Smuggling & Black Market Risks: Smart contracts meticulously track organ transfers, while AI flags suspicious patterns.

• Donor Incentive Gaps: NFT rewards encourage participation, acknowledging life-saving contributions and building a rewarding donor ecosystem.

Key Features

1. Seamless Onboarding and Verification

• Secure health document uploads stored on IPFS (via Pinata).

• AI reads and extracts health data using OCR.

• Smart contracts verify donation eligibility automatically.

2. Blood Camp Registration & Staking Mechanism

• Hospitals/NGOs stake funds to register blood camps, ensuring accountability.

• Staked funds are refunded upon successful event completion.

• Partial or complete fund loss occurs for failed/canceled events.

3. NFT Rewards & Inventory Management

• Users register for donation camps and receive unique QR codes.

• After successful donation, QR codes are scanned to mint NFTs.

• Hospital blood inventories update in real time through blockchain logs.

4. Organ Donation Cycle with Smuggling Detection

• Every organ transfer is recorded on-chain for full traceability.

• AI analyzes blockchain patterns to detect suspicious activities.

• Potential smuggling cases trigger automatic alerts to law enforcement.

5. AI-Powered Document Analysis

• Uploaded health documents are processed via Tesseract OCR.

• AI structures and stores parsed data securely on IPFS.

• Smart contracts determine donation eligibility based on extracted data.

Platform Workflow

1. User Registration: Upload health documents → AI processes via OCR → Smart contract verifies eligibility.

2. Camp Registration: Hospital/NGO stakes funds → Event added to the platform.

3. Donation Process: User registers → Receives QR code → Donates blood or organs.

4. Post-Donation: QR code scanned → NFT minted → Hospital inventory updated.

5. Organ Donation: Organ transfer recorded on-chain → AI monitors transactions → Suspicious activities flagged.

Benefits

For Users

• Faster, AI-powered eligibility checks.

• NFT rewards gamify and acknowledge donations.

• A secure, lifelong on-chain donation history.

For Hospitals & NGOs

• Transparent, traceable donation cycles.

• Reduced admin burdens and faster document verification.

• Real-time blood and organ inventory tracking.

For Law Enforcement

• On-chain organ data aids forensic investigations.

• AI pattern analysis accelerates smuggling detection.

• Faster responses to flagged transactions reduce illegal activities.

Future Prospects

1. IoT Integration: Connect Crimson to smart devices for live health data and automatic eligibility updates.

2. QR-Based Features: Enable QR scanning for donor registration, live donation tracking, and instant medical data access.

3. Decentralized Health Network: Expand Crimson into a global health data network for faster research, organ matching, and patient care.
