How CopyrightChains Works

				
					
// Simplified example of a CopyrightChains licensing smart contract
contract CopyrightLicense {
    address public creator;
    uint public royaltyPercentage;
    mapping(address => bool) public licensees;

    event LicenseGranted(address licensee, uint amount);
    event RoyaltyPaid(address creator, uint amount);

    constructor(uint _royaltyPercentage) {
        creator = msg.sender;
        royaltyPercentage = _royaltyPercentage;
    }

    function purchaseLicense() public payable {
        require(msg.value > 0, "Payment required");

        // Calculate royalty
        uint royaltyAmount = (msg.value * royaltyPercentage) / 100;

        // Transfer royalty to creator
        payable(creator).transfer(royaltyAmount);

        // Grant license
        licensees[msg.sender] = true;

        emit LicenseGranted(msg.sender, msg.value);
        emit RoyaltyPaid(creator, royaltyAmount);
    }

    function verifyLicense(address user) public view returns (bool) {
        return licensees[user];
    }
}
