Example of a Simple Smart Contract

pragma solidity ^0.8.0;

contract SimpleAgreement {
    address public partyA;
    address public partyB;
    uint public amount;
    bool public fulfilled;

    constructor(address _partyB, uint _amount) {
        partyA = msg.sender;
        partyB = _partyB;
        amount = _amount;
    }

    function fulfillAgreement() public payable {
        require(msg.sender == partyB, "Only Party B can fulfill");
        require(msg.value == amount, "Incorrect amount");
        fulfilled = true;
        payable(partyA).transfer(amount);
    }
}

Identity Management

Blockchain provides secure and decentralized identity solutions, useful for:

• Digital identity verification
• Access control systems
• Personal data management
