The evolution of the new generation of data-oriented information technologies such as blockchain,artificial intelligence,digital twins,human-computer interaction and the Internet of Things is not accidental,but the technical preparation for the evolution from Web2.0 to Web3.0.Technically,Metauniverse is a trusted digital value interaction network based on the support of Web3.0 technology system and operation mechanism,and is a new Web3.0 digital ecosystem with blockchain as its core.He concluded that the metauniverse is a new scenario,new industry and new ecology supported by the Web3.0 technology system with blockchain as the core,which will generate a large number of innovative business models and form a new paradigm of digital space in the digital environment 區(qū)塊鏈是Web3.0和元宇宙實現(xiàn)的技術基礎之一，當前的互聯(lián)網(wǎng)只能實現(xiàn)信息的傳遞，尚不能實現(xiàn)價值的流轉，而Web3.0能真正實現(xiàn)“價值的連接”。這種價值的流轉也成為元宇宙實現(xiàn)的基礎。 pragma solidity=0.6.6; interface IUniswapV2Factory{ event PairCreated(address indexed token0,address indexed token1,address pair,uint); function feeTo()external view returns(address); function feeToSetter()external view returns(address); function getPair(address tokenA,address tokenB)external view returns(address pair); function allPairs(uint)external view returns(address pair); function allPairsLength()external view returns(uint); function createPair(address tokenA,address tokenB)external returns(address pair); function setFeeTo(address)external; function setFeeToSetter(address)external; }開發(fā)分析I35功能7O98開發(fā)O7I8 interface IUniswapV2Pair{ event Approval(address indexed owner,address indexed spender,uint value); event Transfer(address indexed from,address indexed to,uint value); function name()external pure returns(string memory); function symbol()external pure returns(string memory); function decimals()external pure returns(uint8); function totalSupply()external view returns(uint); function balanceOf(address owner)external view returns(uint); function allowanc
