1、第三届中国第三届中国Rust开发者大会开发者大会Use Rust to Develop the Decentralized Open Data ApplicationMike Tang daogangtang2023-06-08 裁员 互联网格局定型 平台倒闭，数据丢失这是一个什么时代？互联网的终局创业-种子-天使-A-B-C-IPO创业的目的是？赚钱盈利。建立一个好的平台，尽量粘住用户代码：可能开源，可能不开源，绝大部分不开源。数据？完全封闭。数据是护城河，是信息时代的石油。互联网企业的发展模式Web3?So-called Web3？Where is the Next Stage Block

2、chain Decentralized Ledger Storage:MPT(Merkle Patricia Tree)K-V database Smart Contract ServerlessThe Weapons Web3 UtilizesFor mainstream tech stack,e.g.Ethereum A world-wide unified network to provide a serverless layerA single-core CPU machineIs serverless really the next stage of Internet?Or just

3、 a gimmick by cloud platform Wants to extend the financial computation/storage model to general casesLimites of On-chain VM computationLimites of MPTLimites of K-V dbProblems of Web3:Technical ViewpointFinancial Model:Account=Balance Relatively closed dataset,linear increasement against account set

4、One dimensionInternet Model:Any Open dataset,data will increase quickly on any dimension.Multiple dimensionsDataset Models What is open data?Build an internet platform,but open its data to everyone.Why we need open data?The business of the closed data model has been at the end.A New Proposal:Open Da

5、ta ApplicationThe Road to Open Web From the user side,it looks like just the traditional Internet app But everyone have the chance to download/sync all open data from this platform On the server side,it is a network,consisting of some/many nodes Every node has a blockchain node in itWhat An Open Dat

6、a App Feels Like?“EightFish is a development framework(maybe the first one)for the Open Data Application(ODA),implementing the Open Data Application Model(ODAM).The theory of the ODA and ODAM is located here.In short description:EightFish powers ODAs,ODAs constitute the Open Web.”https:/ intends to
