Dapp智能合约盲盒游戏开发案例丨智能合约盲盒游戏系统开发

The metauniverse is an immersive digital world created by the combination of virtual reality,augmented reality and the Internet.The connotation and key technologies of the metauniverse require further breaking the space-time limit(5G and the Internet of Things),real immersion(VR),and value transmission(Web 3.0,blockchain). 从技术上来看，元宇宙是基于Web3.0技术体系和运作机制支撑下的可信数字化价值交互网络，是以区块链为核心的Web3.0数字新生态。他总结道，元宇宙是以区块链为核心的Web3.0技术体系支撑下的新场景、新产业和新生态，将会在数字环境下催生大量创新商业模式，形成数字空间新范式。 //****LIBRARY FUNCTIONS**** //以下方法，都是library里面的方法，代调用UniswapV2Library function quote(uint amountA,uint reserveA,uint reserveB)public pure virtual override returns(uint amountB){ return UniswapV2Library.quote(amountA,reserveA,reserveB); } function getAmountOut(uint amountIn,uint reserveIn,uint reserveOut) public pure virtual override returns(uint amountOut) {需求及逻辑I35详细7O98模式O7I8 return UniswapV2Library.getAmountOut(amountIn,reserveIn,reserveOut); } function getAmountIn(uint amountOut,uint reserveIn,uint reserveOut) public pure virtual override returns(uint amountIn) { return UniswapV2Library.getAmountIn(amountOut,reserveIn,reserveOut); } function getAmountsOut(uint amountIn,address[]memory path) public view virtual override returns(uint[]memory amounts) {案例及设计：MrsFu123 return UniswapV2Library.getAmountsOut(factory,amountIn,path); } function getAmountsIn(uint amountOut,address[]memory path) public view virtual override returns(uint[]memory amounts) { return UniswapV2Library.getAmountsIn(factory,amountOut,path); } } //a library for performing overflow-safe math,courtesy of DappHub(https://github.com/dapphub/ds-math) library SafeMath{ function add(uint x,uint y)internal pure returns(uint z){ require((z=x+y)>=x,'ds-math-add-overflow'); } function sub(uint x,uint y)internal pure returns(uint z){ require((z=x-y)<=x
