无人真人直播系统开发项目案例/功能详情/设计方案/源码说明
区块链、人工智能、数字孪生、人机交互、物联网等面向数据的新一代信息技术的演进并非偶然,而是从Web2.0向Web3.0演进的技术准备。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。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。
Web3.0致力于改变中心化平台对数据的控制,从这个角度来看,Web3.0项目不会将数据存储在中心化的服务器中。因此,Web3.0项目会有海量的数据存储需求,分布式存储是重要基础设施。
