Web 3.0, also known as the "Value Internet", is a new stage of Internet development in traditional terms. It builds upon the current Internet (or what you might call Web 2.0), but introduces changes that bring the Internet to a whole new level of development.
Computer scientists and Internet experts believe that these changes will make the Internet smarter and our lives easier.
Practitioners in the digital cryptocurrency industry have higher expectations for Web 3.0. They are now looking forward to breaking the monopoly of traditional Internet giants and creating a brand new world of freedom.
However, if you want to truly understand Web3.0 and understand "value-for-money Internet", you must start learning from the history of Internet development.
We start from Web1.0, what is Web1.0?
Web 1.0 refers to the first generation of the Internet, which is the Internet from the late 1990s to the early 2000s, and it is composed of static web pages. The content of these pages is fixed and cannot be updated by users themselves, so Web 1.0 is also called the static Web. For this era, many young people born after 1990 may be very unfamiliar, as it was a non-interactive Internet era.
Websites during the Web 1.0 era were typically static, and the content could not be updated by users themselves. The content of Web 1.0 websites was manually updated by website developers on servers, and users could only access this content through browsers.
Websites during the Web 1.0 era were usually built on HTML and often contained many static web pages. The content of these pages was fixed and could not be updated by users themselves. Web 1.0 websites generally only provided information browsing functions and did not support interactive applications.
In simple terms, web pages in the Web 1.0 era were more like electronic newspapers. You could only browse the information on them, or in today's terms, your permissions were limited to "read-only" and you could not "edit."
The Internet during the Web 1.0 era was mainly used for information browsing and dissemination. With the development of Internet technology, the Web 2.0 era's Internet focused more on user interaction and social networking, supporting various online applications such as forums, blogs, social networks, and more.
What is Web 2.0?
Web 2.0 refers to the Internet after 2000, which is composed of dynamic web pages. Web 2.0 websites are usually built on web services and support various online applications such as forums, blogs, social networks, and more. Web 2.0 websites typically have stronger interactivity and social features, allowing users to update content themselves and interact with other users.
The main difference between Web 1.0 and Web 2.0 lies in their levels of interactivity and social features. Websites in the Web 1.0 era were usually static, with content that could not be updated by users themselves, while websites in the Web 2.0 era typically have interactivity and social features, allowing users to update content themselves and interact with other users.
The development of Web 1.0 and Web 2.0 marks the evolution of the Internet from a platform for information browsing and dissemination to one that emphasizes user interaction and social networking. With the continuous development of Internet technology, the Internet has now entered the Web 3.0 era.
Let's go back and sort out what exactly Web 3.0 is and why it is called the "Value Internet."
Web 3.0 refers to the third-generation Internet, also known as the Intelligent Web. The Internet in the Web 3.0 era is mainly built on artificial intelligence and big data technologies, which can automatically analyze and understand user needs and provide personalized services.
The Internet in the Web 3.0 era is mainly used for information browsing and dissemination. With the development of Internet technology, the Web 3.0 Internet focuses more on user experience and personalized services, supporting various online applications such as virtual reality and augmented reality.
Therefore, Web 3.0 is also called the Intelligent Internet or Immersive Internet.
Have you noticed an interesting phenomenon? The development of the Internet follows the same trajectory as the development of movies, from static to dynamic to 3D (immersive networks). So, can you understand Web 3.0 now?
In simple terms:
On the technical level of Web 3.0: Blockchain technology is the cornerstone, and artificial intelligence, big data technology, and virtual reality technology form the framework. Blockchain brings data authentication and decentralization, while artificial intelligence, big data technology, and virtual reality technology provide intelligent experiences.
On the performance level of Web 3.0: Intelligent networks and the metaverse. The most prominent example of intelligent networks is whole-house intelligence, while the most prominent example of the metaverse is virtual reality.
At the same time, blockchain technology brings data authentication and decentralization, making the origin of data traceable and returning the value of data to the users themselves. Under the Web 3.0 framework, each participant is the owner and beneficiary of the value of their own data. This is data authentication and value return.
Web3 is the production relationship of the next-generation Internet.
Its core is the decentralized construction method, and its philosophy lies in the concept of decentralization. The value of Web3 lies in establishing a new form of ownership after nobles, and capitalists. That is, if we can have a system of "I create—I own—I use," then "I" can directly trade and exchange with my creations, making "my property" truly "belong to me and serve me." Many elements of Web3 may not be entirely new, but the "production relations" and "ownership systems" brought by Web3 are brand new, which is where the value of Web3 lies.
Web 3.0 is a vision for the future of the Internet, emphasizing the use of structured data and machine-readable information so that computers can more easily understand and process the vast amount of information available on the network; emphasizing data authentication, making data processing decentralized and data ownership clear.
Structured data
In contrast to the current state of the web, which mainly focuses on providing unstructured information to humans through web pages, the goal of Web 3.0 is to create a network that is easier for machines to understand and process. This can enable a wide range of new applications and services, such as personalized search and recommendation systems, intelligent assistants, and automated data analysis and visualization.
To realize this vision, Web 3.0 relies on many technologies and standards, including:
· Ontologies: Formal definitions of concepts and relationships in specific knowledge domains, which can be used to describe and classify data on the network.
· RDF (Resource Description Framework): A standard for expressing and sharing structured data on the web.
· SPARQL (SPARQL Protocol and RDF Query Language): A query language for accessing and manipulating data stored in RDF format.
· OWL (Web Ontology Language): A language for expressing ontologies in a machine-readable form.
Decentralization and data authentication
In the context of blockchain technology, Web 3.0 refers to the decentralization and data authentication of the Internet, where decentralized, blockchain-based systems play a central role in enabling new applications and services.
1. Decentralization
Web 3.0 blockchain applications are typically characterized by the use of decentralized protocols, enabling users to interact directly with each other without the need for a central institution or intermediary. This decentralized architecture has the potential to enable new applications and services that are more transparent, secure, and resilient than those based on traditional centralized systems.
Some examples of Web 3.0 blockchain applications include:
· Decentralized Finance (DeFi) platforms: These are blockchain-based platforms that allow users to access financial services, such as loans, lending, and trading, without the need for traditional financial institutions.
· Decentralized marketplaces: These are blockchain-based platforms that allow users to directly buy and sell goods and services without a central market operator.
· Decentralized identity systems: These are blockchain-based systems that allow users to control and manage their own digital identities, rather than relying on centralized institutions to do so.
2. Data Verification
In the context of blockchain technology, data verification refers to the process of verifying the authenticity and integrity of data stored on the blockchain. This is achieved through the use of cryptographic techniques (such as hashing and digital signatures) that enable users to verify whether the data has not been tampered with or altered in any way.
Data verification is an important aspect of blockchain technology because it helps to ensure the integrity and reliability of data stored on the blockchain. This is especially important in applications that use data to make decisions or facilitate transactions, such as in supply chain management or various methods of implementing data verification on the blockchain include:
· Hashing: This involves using a cryptographic hash function to generate a fixed-length, unique fingerprint of a piece of data. Hashing allows users to verify whether a piece of data has not been tampered with, as any changes to the data would result in a different hash value.
· Digital signatures: This involves signing a piece of data using a private key and verifying the signature using a public key. Digital signatures enable users to verify the authenticity of a piece of data, as forging a signature is computationally infeasible without access to the private key.
· Consensus algorithms: These algorithms are used to reach consensus among participants on a blockchain network regarding the validity of specific data. Consensus algorithms can be used to verify the authenticity and integrity of data stored on the blockchain.
Web 3.0 blockchain applications are still in the early stages of development, and it is not yet clear how they will shape the future of the internet. As of now, the future of Web3 will bring about several changes:
Changes in the way we create content
In the past, your creations were either for a platform (such as writing online) or for a company (such as writing PPTs for your boss every day). A small number of people could benefit from their creations, while others received a salary, and you had no idea how much value your boss created from your PPTs. In the future, your creations will belong to you, and those who use them will pay for them. PPT is just an example; you can create a large-scale game or a solution to a real-world problem, form a team using DAO, finance it with DeFi, and make purchases with cryptocurrency.
Changes in the relations of production
Your father worked in a factory with a fixed salary, but he could be laid off; you work in a company with a salary and can change jobs, but you have to sign a labor contract. In the future, most people won't need to enter factories or companies, as smart contracts will replace traditional contracts; DAO will handle human resources and organizational relationships, and other services such as insurance can be directly purchased and implemented through code.
Isn't that cool?
Of course, these are just the basics, and the future of Web3 is open to your imagination and contribution.
