區(qū)塊鏈、人工智能、數(shù)字孿生、人機(jī)交互、物聯(lián)網(wǎng)等面向數(shù)據(jù)的新一代信息技術(shù)的演進(jìn)并非偶然，而是從Web2.0向Web3.0演進(jìn)的技術(shù)準(zhǔn)備。從技術(shù)上來(lái)看，元宇宙是基于Web3.0技術(shù)體系和運(yùn)作機(jī)制支撐下的可信數(shù)字化價(jià)值交互網(wǎng)絡(luò)，是以區(qū)塊鏈為核心的Web3.0數(shù)字新生態(tài)。元宇宙是以區(qū)塊鏈為核心的Web3.0技術(shù)體系支撐下的新場(chǎng)景、新產(chǎn)業(yè)和新生態(tài)，將會(huì)在數(shù)字環(huán)境下催生大量創(chuàng)新商業(yè)模式，形成數(shù)字空間新范式。

　　Web3.0致力于改變中心化平臺(tái)對(duì)數(shù)據(jù)的控制，從這個(gè)角度來(lái)看，Web3.0項(xiàng)目不會(huì)將數(shù)據(jù)存儲(chǔ)在中心化的服務(wù)器中。因此，Web3.0項(xiàng)目會(huì)有海量的數(shù)據(jù)存儲(chǔ)需求，分布式存儲(chǔ)是重要基礎(chǔ)設(shè)施。
