量化合約系統(tǒng)開發(fā)運(yùn)營(yíng)版丨量化合約開發(fā)源碼版及策略
智能合約dapp開發(fā)技術(shù)主要由以太坊區(qū)塊鏈網(wǎng)絡(luò)提供支持，該網(wǎng)絡(luò)提供了一系列的智能合約技術(shù)，These smart contracts allow developers to quickly and safely build powerful dapps.The development technology of smart contract dapp mainly includes Ethereum smart contract language Solidity,Ethereum smart contract framework Truffle,Web3.js,Ethereum blockchain browser Mist,etc
Web3.0通過將信息交互從屏幕轉(zhuǎn)移到物理空間，改變了終端用戶體驗(yàn)，因而也有稱Web3.0為“空間網(wǎng)絡(luò)（Spatial Web）”。該“空間網(wǎng)絡(luò)”包括空間交互層（利用智能眼鏡或語(yǔ)音等實(shí)現(xiàn)實(shí)時(shí)信息交互）、數(shù)字信息層（借助傳感和數(shù)字映射為每一個(gè)對(duì)象創(chuàng)建數(shù)字孿生）和物理層（通過感觀了解和體驗(yàn)的世界）。VR/AR is the main gateway of the space network,AI/ML promotes interaction with machines or devices,5G/6G and other new generation network communication technologies and edge computing are enabling technologies to optimize interactive experience,and blockchain promotes the realization of a truly open and democratic ecosystem.
Web3.0基礎(chǔ)設(shè)施主要包括節(jié)點(diǎn)基礎(chǔ)設(shè)施、存儲(chǔ)、預(yù)言機(jī)、安全審計(jì)、數(shù)據(jù)分析平臺(tái)、錢包、開發(fā)工具等。開發(fā)威：MrsFu123 如錢包服務(wù)用戶鏈上資產(chǎn)的存儲(chǔ)，是Web3.0的重要入口，如Metamask（加密貨幣錢包）、WalletConnect（錢包通用協(xié)議）等。
