1.web3.0是什么
GoogleCEO埃里克施密特将其定义为：Web3.0是一系列组合在一起的应用。Web3.0这一术语结合了不同思想来描述互联网的功能及其影响将沿着几个不同的方向进化;这些进化方向包括将网络转变成为一个数据库,各种非浏览器应用程序可以获取网络内容,使网络朝着人工智能技术、语义网、地理空间或3D空间等方向发展。
GoogleCEO Eric Schmidt defines it as a series of applications that web3.0 is a combination of applications. Web3.0 is a term that combines different ideas to describe the functionality of the Internet and its effects and evolves along several different directions; these evolutionary directions include transforming the network into a database where various non-browser applications have access to network content, moving the network towards artificial intelligence technology, semantic networks, geospatials or 3D spaces.
2.web3.0的特点
2.web3.0 Features
(1)去中心化(Decentralization)
(1) Decentralization
去中心化是Web 3.0 的核心原则。信息不再只在固定位置，而是分散储存。没有了中心控制点，等如删除了制造商与消费者之间的中间商(Intermediate Trader)，用户数据将不再受Meta(Facebook)和Google等科技巨企控制，可以可降低公司或政府的审查风险、拒绝服务 (DoS) 攻击的有效性，确保个体用户的私隐资料甚至保留所有权。
Decentralization is the core principle of Web 3.0. Information is no longer just a fixed location, but rather a decentralized storage. Without a central control point, e.g., removing intermediaries between manufacturers and consumers (Intermediate Trader), user data will no longer be controlled by technology giants such as Meta (Facebook) and Google, which can reduce the effectiveness of corporate or government censorship, denial of services (DoS) attacks, and ensure that private information from individual users is even retained.
(2)去信任化及无权限化(Trustless and Permissionless)
"Trustless and Permissionless"
去中心化这个原则，由去信任化及无权限化去实践。Web 3.0中的「去信任化」，即是网络允许参与者直接交流互动而无需通过受信任的中介;「无权限化」意味着任何人不用经过管理机构授权的情况下参与。因此，Web 3.0应用程序将运行在区块链或分散的点对点网络或其组合上 —— 这种分散的应用程序又被称为DApp。
Decentralizing this principle by de-trusting and de-authorization. " Detrusting " in Web 3.0 means that the network allows participants to interact directly without trusting intermediaries; " incompetent " means that no one is allowed to participate without the authority's authorization. Therefore, the Web 3.0 application will run on a block chain or a decentralized point-to-point network or its combination -- a decentralized application called Dapp.
(3)人工智能与机器学习(Artificial Intelligence and Machine Learning)
(3) Artificial Intelligence and Machine Learning
在 Web 3.0 中，通过Semantic Web(语意网)的概念和自然语言处理的技术，计算机将能够像人类一样理解信息。Web 3.0更会使用机器学习，透过数据和演算法来模仿人类的学习方式，并且愈渐准确。这些功能不仅限於现时互联网上的行为定向广告(Behavior Targeting Advertising)，未来更有助应用於药物设计、材料开发、气候建模等不同领域。
In Web 3.0, computers will be able to understand information as much as humans through the concept of Semantic Web and the technology of natural language processing. Web 3.0 is more likely to use machine learning, imitate human learning through data and algorithms, and is becoming more accurate. These functions are not limited to current behavioral advertising on the Internet, but will be more useful in different areas such as drug design, material development, and climate modelling.
(4) 连通性与无边界网络(Connectivity and Ubiquity)
(4) Connectivity and Ubiquity
借助Web 3.0，信息和内容变得更加互联和无处不在。不同应用程序分析更多的信息和数据，并且愈来愈多日常设备和产品连接到网络。
With Web 3.0, information and content become more interconnected and ubiquitous. Different applications analyse more information and data, and more and more routine equipment and products are connected to the network.
资料使用的实际层面上，预期未来因为Web 3.0 出现而有重大改变。纽约大学未来网络教授Mat Dryhurst表示，过去因为每个社群、网络平台政策的不同，形成资料的「walled garden」(高墙花园)，令用户虽然拥有自身数据资料，却无法完全随心所欲转移、掌握和运用。当未来资料可以放在区块链上，用户就可真正拥有，并带同这些个人资料到任何网站。
At the practical level, information is expected to change significantly in the future because of Web 3.0. Professor Mat Dryhurst, a future network professor at New York University, said that in the past, the "waled garden" (high wall garden) of information had been created because of the differences in policies of each community and network platform, making it impossible for users to move, master, and use their own data completely as they wanted. When future information could be placed on a block chain, users could really own it and bring it with them to any website.
3.web3.0的基础设施
(1) 区块链和跨链技术
Web3.0这个名字出现得比区块链更早。但在区块链兴起之前，Web3.0因缺乏解决方案只能停留在概念阶段。随着区块链技术的发展和加密货币投资者的增多，以太坊、Polkadot等区块链生态中涌现出一批与Web3.0相关的项目。因此，区块链技术奠定了Web3.0发展的基础。就整个区块链行业而言，多链并存的格局还会持续很长时间。在这种情况下，不同区块链生态的Web3.0用户有进行交互的需求，跨链技术会在这个过程中发挥重要作用。目前，主要的跨链技术包括公证人机制、侧链或中继、哈希时间锁定、分布式私钥控制等。
The name Web3.0 appears earlier than the block chain. But before the block chain rises, Web3.0 can only remain at the conceptual stage owing to a lack of solutions. With the development of block chain technology and the growth of encrypted money investors, a number of projects related to Web3.0 have emerged in the ecology of the block chain, such as the Taiku, Polkadot, and others. Thus, block chain technology has laid the foundation for Web3.0 development.
(2) 去中心化身份
(2) to centralize
在整个Web3.0的架构中，去中心化身份(Decentralized Identity，DID)是至关重要的一环。DID与Web3.0的核心理念相符，允许用户拥有并控制自己的数字身份。DID中包含用户的身份信息和隐私数据，只有在经过用户授权的情况下才能使用，具有安全性、可验证和互操作性等特点。DID系统以去中心化的方式实现身份的发现、识别和验证，不依赖中心化身份系统的审核和许可。
In the entire Web3.0 architecture, decentralised identity is an essential part. The DD is consistent with the core concept of Web3.0 and allows users to own and control their digital identity. The DD contains user identification information and privacy data that can only be used with user authorization, with features such as security, authentication and interoperability. The DD system enables identification, identification and authentication in a decentralised manner, and does not rely on centralised identification system verification and licensing.
(3) 分布式存储
(3) Distributed Storage
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。相比传统的中心化存储，分布式存储具有安全性高、隐私保护、防止单点失效等优势。但在实际应用过程中，分布式存储面临着可靠性、用户体验和监管政策等方面的风险。当前主要的分布式存储项目包括Filecoin和Arweave等。
Web3.0 is committed to changing the centralization platform's control over data. From this perspective, Web3.0 will not store data in a centralized server. Therefore, Web3.0 will have a large amount of data storage needs, distributed storage being an important infrastructure. Distributive storage has the advantages of high security, privacy protection, and preventing single-point failures, as compared to traditional centralized storage. But in practical applications, distributed storage faces risks in terms of reliability, user experience, and regulatory policy.
(4) 隐私计算
(4) Privacy Calculating
在Web2.0中，中心化平台的商业模式普遍是通过用户的数据资源获取流量和利润。在Web3.0中，也存在对数据的使用和分析需求。但是考虑到数据安全和个人隐私，需要在用户的数据和隐私得到保障的前提下，通过隐私计算的方式完成计算任务。安全多方计算是隐私计算的一种解决方案，可以使互不信任的参与方之间保护隐私的情况下实现协同计算。
In Web 2.0, the business model of the centralized platform is generally to generate flows and profits through user data resources. In Web3.0, there is also a need for data use and analysis. But, given the security of data and privacy of individuals, computational tasks need to be performed through privacy calculations, with user data and privacy guaranteed. Secure multi-partition calculations are a solution to privacy calculations that allow for coordinated calculations among distrusting participants to protect privacy.
4.web3.0的应用举例
4.web3.0 Examples of applications
(1)去中心化自治组织(DAO)
DAO是在线成员共有的社区，由成员的共识而非集中领导来管理。
DAO is a community shared by online members and is managed by consensus rather than by centralized leadership.
(2)去中心化金融(DeFi)
(2) DeFi
去中心化金融或 "DeFi "是指金融领域(储蓄、贷款和外汇兑换)的去中心化应用。
Decentralized finance or & quit; DeFi & quit; decentralized application in the financial field (savings, loans and foreign exchange).
(3)稳定币和中央银行数字货币(CBDCs)
(3) Stable Currency and Central Bank Digital Currency (CBDCs)
稳定币是私人发行的加密货币，相对于美元或欧元，稳定币会在一段时间内保持稳定价值。有法币抵押的稳定币:例如与美元挂钩的稳定币，保有法币的资产储备，以匹配每个代币的发行价值。其他项目通常是通过抵押数字资产或自动执行智能合约的算法保持来稳定。中央银行数字货币(CBDCs)是由政府发行的数字货币，象征着国家主权和义务。
Stable currency is a private, encrypted currency, which will remain stable over time in relation to the United States dollar or the euro. Stable currency with a French currency: for example, a stable currency pegged to the dollar, with a reserve of assets in French to match the issuing value of each currency.
(4)隐私和数字基础设施
目前的许多区块链网络存在的局限性是——设计完全透明。但是，密码学新领域的前沿研究，使得从数学上证明信息的有效性成为可能，而无需提供信息本身。
The limitations of many of the current block chain networks are that the design is fully transparent. However, cutting-edge research in new areas of cryptography makes mathematical proof of the validity of the information possible without the need to provide the information itself.
(5)创造者经济 (Creator Economy)
(5) Creative Economy
创作者经济，是新兴的创作者社区，如艺术家、音乐家、游戏开发者等等，直接与支持者(粉丝)联系，在没有中介的情况下进行合作，创造者们能够获得独立收入来源。
The creative economy is an emerging community of creators, such as artists, musicians, game developers, etc., who are in direct contact with their supporters (crowders), cooperate without intermediaries, and creaters have access to independent sources of income.
(6)链游(Gamefi)
(6) (Gamefi)
基于区块链的游戏，是指构建在区块链技术上的游戏。
A block-chain-based game is a game built in block-chain technology.
