Blockchain-based Charity Donation Platform

Objective:

To build a transparent, traceable, and secure platform for managing and distributing charity donations using blockchain technology, ensuring donors can track exactly how their funds are used and increasing trust in charitable organizations.

Key Features:

Transparent Donation Tracking: All donations are recorded on the blockchain and viewable by anyone.

Smart Contracts for Fund Allocation: Automate the release of funds to specific causes or milestones.

Donor Verification & Receipts: Donors receive digital proof of donation (like a token or receipt).

Charity Verification System: Only verified NGOs or charities can receive funds.

Real-Time Impact Reports: Donations linked to results/progress reports stored on-chain or IPFS.

Multi-Currency Support: Accepts donations in multiple cryptocurrencies (ETH, BNB, USDT, etc.).

Technologies Used:

Blockchain Platforms:

Ethereum – Popular for deploying smart contracts and handling token-based donations.

Polygon / Binance Smart Chain (BSC) – More scalable and cost-effective alternatives.

Hyperledger Fabric – Suitable for private charity networks or enterprise-grade systems.

Smart Contract Languages:

Solidity – Used to write smart contracts on Ethereum-compatible chains.

Chaincode (Go/Java) – For Hyperledger-based implementations.

Frontend Technologies:

React.js / Vue.js – For building donation dashboards and NGO profiles.

Web3.js / Ethers.js – For connecting the frontend to the blockchain and handling transactions.

Storage Solutions:

IPFS / Filecoin / Arweave – For storing and sharing impact reports, verification documents, or receipts off-chain.

Cloud DB (MongoDB / Firebase) – Optional for additional off-chain data.

Security & Encryption:

SHA-256 / Keccak-256 – For generating secure hashes of donation records or documents.

Public/Private Keys – Used for signing and verifying transactions or digital receipts.

Other Tools:

The Graph – For efficient querying of blockchain donation data.

MetaMask / WalletConnect – Wallet integration for easy and secure donations

How It Works:

NGO Registration: Charities register and get verified on the platform.

Campaign Creation: Verified charities create donation campaigns with goals and milestones.

Donor Contribution: Users connect their wallet and donate crypto to a chosen campaign.

Smart Contract Management: Donations are held in a smart contract and released upon milestone completion or manual approval.

Impact Tracking: NGOs upload receipts or reports, stored on IPFS, linked to donation transactions.

Audit Trail: Donors and the public can view the entire donation history and fund usage on-chain.

Benefits:

Transparency & Trust: Donors can see where their money goes and how it’s used.

Accountability: Smart contracts enforce milestone-based fund release.

Security: All donations are traceable, immutable, and secure from tampering.

Lower Fees: Reduced costs compared to traditional donation platforms.

Global Access: Anyone worldwide can donate instantly using crypto.

Real-Time Impact: Donors receive updates and can track campaign progress live.
