佛萨奇2.0矩阵系统设计开发（Solidity编程示例）

NFT佛萨奇2.0矩阵是一个基于区块链的虚拟艺术品市场，在这个智能合约中，我们从ERC721继承了一个标准的NFT合约。它通过智能合约来实现对售出艺术品的所有权确认和管理。

我们还可以通过使用链上数据存储和加密算法来确保佛萨奇2.0矩阵的安全性，并使用去中心化身份验证方法来确认用户的身份。

用Solidity编写的简单代码示例：

复制代码pragma solidity ^0.8.0;
import "@openzeppelin/contracts/token/ERC721/ERC721.sol";
        contract ForsageTronX {
            address public owner; uint public total = 16;
                uint public step = 0.1 ether;
            uint public index = 0; mapping (address => uint) public investors;
                mapping (address => uint) public investments;
}
    mapping (address => uint) public times;

mapping (address => uint) public levels;
address[16] public accounts; 

      constructor() public { owner = msg.sender; accounts[0] = 0x8Af01cEA98881B83e29B9B8D57d3cF186C3A3A64; accounts[1] = 0xC429db635D9d5DC8b1B2B06B5D5Ba40F5B8a236E; accounts[2] = 0xD25685857d88D10217f7D3C3d2f7a8aAc79f7387; accounts[3] = 0x50DC04b062c10bA1A46048f8b87BbB3C3D16e9A9;
contract NFTMatrix is ERC721 {
    uint256 public tokenId;
    
    constructor() ERC721("NFTMatrix", "NFTM") {
​ }
 
 function mint(address to) external {
        tokenId++;
        _safeMint(to, tokenId);
    }
}
