4. Workflow

4.1 Vendor Onboarding

  1. Vendor registers and submits halal certification.
  2. Certification is verified and stored on the blockchain.
  3. Admin approves vendor, allowing product listing.

4.2 Product Listing

  1. Vendor lists product with:
    • Name, description, price.
    • Halal certificate ID (stored on blockchain).
    • Image (stored on IPFS).
  2. Smart contract verifies the halal certification.

4.3 Customer Workflow

  1. Customer browses products using filters (e.g., halal-certified).
  2. Adds products to cart and proceeds to checkout.
  3. Payment is processed via a smart contract.
  4. Order status is updated on blockchain.

4.4 Transaction Workflow

  1. Customer pays using a smart contract (escrow system).
  2. Funds are held until delivery is confirmed.
  3. Payment is released to the vendor.

            isValid: true
        });
    }

    function verifyCertification(string memory _certificateId) public view returns (bool) {
        return certifications[_certificateId].isValid && certifications[_certificateId].expiryDate > block.timestamp;
    }
}

        uint256 price;
        address payable vendor;
        bool isSold;
    }

    uint256 public productCount = 0;
    mapping(uint256 => Product) public products;

    function listProduct(string memory _name, uint256 _price) public {
        productCount++;
        products[productCount] = Product({
            id: productCount,
            name: _name,
            price: _price,
            vendor: payable(msg.sender),
            isSold: false
        });
    }

    function buyProduct(uint256 _id) public payable {
        Product storage product = products[_id];
        require(product.id > 0, "Product does not exist");
        require(!product.isSold, "Product already sold");
        require(msg.value == product.price, "Incorrect payment");

        product.vendor.transfer(msg.value);
        product.isSold = true;
    }
}

7. Deployment

Smart Contracts

  • Deploy using Hardhat or Remix to Goerli, Polygon Mumbai, or Binance Smart Chain Testnet.
