NFT作为游戏内资产的一种独一无二的表示，随着时间的推移获得价值，之后可以出售以获取利润。详细I8O-系统2857-开发8624通过支持NFT形式的游戏内收藏品的铸造、购买和交易，数字游戏可以为其消费者提供更逼真的游戏体验。在去中心化交易所，用户可以收集和出售Gaming NFT，获得奖品，甚至兑现他们的代币。
让我们仔细看看游戏NFT的概念。NFT Gaming NFT Marketplace，这是一个游戏NFT的交易市场。将NFT市场整合到数字游戏中可以让游戏玩家通过他们的游戏资产获利，从而为他们提供真正的游戏体验。
NFT在游戏中意味着什么？
The global game industry is divided into three parts:PC,game console and mobile game.The capital flow in each medium is unidirectional,which is only beneficial to game developers and persists.Players of traditional game organizations are more likely to spend a lot of money,but have little or no opportunity to earn value for themselves.They first buy expensive game equipment,such as game consoles.Then,they must spend money to get in game materials and exclusive functions after entering the game environment.
NFT的另一个优点是它们可以在游戏结束后被构建以保持其价值。NFT可用于各种游戏场景，因为它们是独特的、可验证的和不可变的。因此，NFTs有潜力显着扩大游戏经济并导致新游戏的开发和新游戏类别的建立。
NFT在游戏行业的重要性：

function transferAndCall(address to,uint value,bytes data)returns(bool success);
event Transfer(address indexed from,address indexed to,uint value,bytes data);
}
contract ERC677Receiver{

}
/**

* dev Basic version of StandardToken,with no allowances.
*/
contract BasicToken is ERC20Basic{
using SafeMath for uint256;
mapping(address=>uint256)balances;
验证原始游戏内资产的真实性。

* param _to The address to transfer to.
* param _value The amount to be transferred.
*/
function transfer(address _to,uint256 _value)returns(bool){

*/
function balanceOf(address _owner)constant returns(uint256 balance){
return balances[_owner];
}
}
验证游戏内资产的唯一性。

*/
contract StandardToken is ERC20,BasicToken{
mapping(address=>mapping(address=>uint256))allowed;
跟踪资产的所有权并证明它。
/**

function transferFrom(address _from,address _to,uint256 _value)returns(bool){
var _allowance=allowed_from;
//Check is not needed because sub(_allowance,_value)will already throw if this condition is not met
//require(_value<=_allowance);
balances[_from]=balances[_from].sub(_value);
balances[_to]=balances[_to].add(_value);
allowed_from=_allowance.sub(_value);
Transfer(_from,_to,_value);
return true;

对游戏内资产进行代币化，以便进行交易。
如何将NFT纳入游戏？
可以合理地假设，在未来，游戏玩家会避免不以NFT形式提供数字资产的游戏。当他们可以选择购买时，谁愿意租房？
The dilemma is how to integrate NFT into games,because NFT may change the game business.Game NFT market is the answer.
如果NFT是游戏行业的未来，您可以通过创建自己的游戏NFT市场成为其中的一部分。将游戏NFT市场纳入游戏概念，允许用户以NFT的形式铸造、购买和销售游戏内收藏品，为他们提供逼真的游戏体验。他们可以收集和交易游戏内配件、武器、角色和其他收藏品的NFT，以及获得奖励、出售他们的代币以获取利润，并在去中心化交易所兑现。
去中心化：
NFT市场在去中心化网络上运行，在去中心化方面使其比中心化游戏服务器更具优势。去中心化的游戏服务器可以更好地保护用户的隐私和匿名性。

超越起源游戏的价值：
一个NFT市场可以连接到多个支持区块链的游戏平台，让游戏玩家能够将资产从一款游戏转移到另一款游戏，从而享受更全面的游戏体验。
function div(uint256 a,uint256 b)internal constant returns(uint256){//assert(b>0);//Solidity automatically throws when dividing by 0 uint256 c=a/b;//assert(a==b*c+a%b);//There is no case in which this doesn't hold return c;}function sub(uint256 a,uint256 b)internal constant returns(uint256){assert(b<=a);return a-b;}function add(uint256 a,uint256 b)internal constant returns(uint256){uint256 c=a+b;assert(c>=a);return c;}}
数据保护：
IPFS等分布式存储技术促进了NFT市场，确保数据高度安全且不可变。
货币化的范围：
正如文章前面提到的，NFT游戏市场最显着的优势之一是它允许游戏玩家通过保持游戏内商品的稀缺性来赚取真钱。真正的和罕见的游戏内宝藏受到收藏家的珍视。由于NFT底层区块链网络固有的不可更改记录，基于NFT的游戏内资产稀缺。

游戏NFT市场如何运作？
基于NFT的游戏在架构和机制以及奖励结构上有所不同。根据游戏的前提，添加了创新元素。另一方面，集成到游戏中的NFT市场的基本功能将通过提供以下功能使创建和交易游戏NFT变得更加容易：
制作NFT：
NFT can be created or mined for various in-game assets,including game characters,collection cards,virtual assets,GIF,Fanart,etc.The game can provide a list of collectibles that can be cast with NFT.
购￥买、出%售和交%易：
The NFT market is a social network where users can buy and sell NFT with others around the world.NFT can be bought and sold separately or in groups.
库存控制：
The NFT marketplace allows users to track their NFT.This inventory makes NFT sales simple,thereby facilitating instant transactions.
投#标：
The storefront displays NFTS purchased in the market.It also informs you of any current or upcoming auctions.Buyers interested in NFT can participate in the auction and bid.
得到报酬：
NFT market provides more cash withdrawal options by accepting multiple payment methods.Users can cash in the proceeds of selling NFT here.
