1. What is Web 3.0?
Web 3.0 refers to the decentralized internet of the future, constructed using blockchain technology. It represents a movement away from the current centralized state of the Internet, known as Web 2.0, which is dominated by major IT corporations such as Google, Apple, Facebook, and Amazon (collectively known as GAFA).
1.1 Changes from Web 1.0 to Web 3.0
Let’s take a quick look at the evolution from Web 1.0 to Web 3.0:
Web 1.0: In the 1990s, the Internet, often referred to as the “era of one-way information transmission,” allowed users to browse websites and exchange emails. However, content creation and publication were primarily limited to companies, with individuals playing a minimal role.
Web 2.0: The Internet of the 2000s and beyond, commonly known as Web 2.0, introduced high-speed internet connections like ADSL and fiber optics, paving the way for platforms such as blogs, social networking sites (e.g., Twitter, Facebook, YouTube), and interactive two-way communication. However, this communication relied on users divulging significant amounts of personal information, raising concerns regarding privacy and security.
Web 3.0: With the advent and rapid advancement of blockchain technology, Web 3.0 aims to eliminate the centralization of Web 2.0. By leveraging the power of blockchain, Web 3.0 seeks to democratize the Internet and address the privacy and security issues associated with Web 2.0.
1.2 What is blockchain?
Before we delve further, let’s briefly explain the core technology behind Web 3.0 – blockchain.
Blockchain is a secure method of recording transactions on the Internet. Unlike traditional servers, where transaction records are stored, blockchain distributes identical records to all participants in the transaction. If one participant attempts to tamper with the record, it will be immediately detected as it deviates from the records held by other participants. Thus, blockchain ensures authenticity by making falsification extremely difficult and necessitates participants to verify each other’s records.
2. Features and Benefits of Web 3.0
Let’s explore the key features and benefits offered by Web 3.0:
2.1 Self-Management of Personal Information
One notable feature and benefit of Web 3.0 is the ability for individuals to self-manage their personal information. In Web 2.0, users are required to provide extensive personal information when using e-commerce platforms and social networking sites. IT companies collect this information to offer their services and generate revenue through targeted advertising. In contrast, Web 3.0 minimizes the need for personal information registration. Users can manage their data, including transaction records, without relying on service providers’ servers. Additionally, users have the option to control the advertisements displayed to them.
2.2 Reduced Risk of Information Leakage
In Web 2.0, personal information stored on IT company servers is susceptible to hacking and subsequent leakage. Incidents like Facebook’s 2019 data breach, which affected over 500 million users, highlight this risk. However, Web 3.0 significantly reduces the need for entering personal information, thus mitigating the risk of data breaches. Furthermore, thanks to blockchain technology, which ensures distributed and secure data management, the probability of information leakage due to cyberattacks is notably low.
2.3 Direct Trading Without Intermediaries
Web 2.0 relies on servers to mediate various transactions, often involving financial institutions that charge commissions. In contrast, Web 3.0 enables direct transactions without the need for intermediaries. Blockchain technology ensures the reliability and security necessary for direct financial transactions, potentially eliminating the fees typically associated with traditional banks.
3. Specific Examples of Web 3.0
Let’s explore specific examples of Web 3.0 applications, including virtual currencies (crypto assets), DAOs (Decentralized Autonomous Organizations), NFTs (Non-Fungible Tokens), and the Metaverse.
3.1 Virtual Currencies (Crypto Assets)
Virtual currencies, often referred to as crypto assets, are electronic currencies controlled by blockchain technology. Unlike traditional currencies guaranteed by central banks, virtual currencies derive their reliability and safety from blockchain. Transaction records, including issuances and transfers, are periodically recorded on the blockchain, making counterfeiting and duplicate payments virtually impossible.
3.2 DAOs (Decentralized Autonomous Organizations)
DAOs, or Decentralized Autonomous Organizations, consist of groups of cryptocurrency investors with a shared purpose. DAO participants collectively manage funds obtained through the independent issuance of virtual currencies, allowing joint investments in projects. Decision-making within DAOs is facilitated through smart contracts written in blockchain-based programming languages. DAOs empower participants to make decisions collectively, eliminating the need for central authority figures.
3.3 NFTs (Non-Fungible Tokens)
NFTs, or Non-Fungible Tokens, represent a technology that records transaction records for specific digital assets, such as digital art, on the blockchain. Historically, ownership of digital data was challenging to establish due to its ease of duplication. However, NFTs link unique digital data to blockchain records, facilitating clear ownership verification. Consequently, digital data can now be assigned intrinsic value as an asset. Multiple NFT marketplaces have emerged, facilitating the active trading of digital art, game items, music, anime, manga, and more.
3.4 Metaverse
The Metaverse represents a three-dimensional virtual space where avatars interact with each other. In the Metaverse, virtual currencies and NFTs play a crucial role. Users can buy, sell, and trade various goods, items, and virtual land within the Metaverse using virtual currencies. These assets hold value through NFTs, thereby creating a vibrant economy within the virtual realm. Notably, the Metaverse has witnessed significant developments, such as “The Sandbox,” where plots of virtual land have been sold within minutes.
4. Examples of Services Utilizing Web 3.0
Web 3.0 has already manifested as functional services. Here are a few examples:
4.1 OpenSea
OpenSea, launched in December 2017, stands as the world’s largest NFT marketplace. It offers a wide range of NFTs, including digital art, music, and photography, featuring works by renowned Japanese artists like Takashi Murakami, Aimi Sekiguchi, and Akihiro Nishino. OpenSea allows anyone to effortlessly convert their creations into NFTs and exhibit them at no cost. The platform supports fixed-price sales and auction formats.
4.2 Brave
Brave, a browser launched in 2019, prioritizes privacy and data protection while delivering performance comparable to or exceeding that of Google Chrome, a dominant browser. A 2020 survey conducted by the Kadokawa ASCII Research Institute revealed that Brave offers the fastest browsing speed among major browsers, officially claiming to be three times faster than Google Chrome.
5. Summary
Web 3.0 represents the next generation of decentralized Internet built on blockchain technology. It aims to break free from the centralized Web 2.0, characterized by tech giants like GAFA (Google, Apple, Facebook, Amazon), and foster a democratized online environment.
Web 3.0 introduces features such as self-management of personal information, reduced information leakage risks, direct peer-to-peer transactions, and encompasses specific applications like virtual currencies, DAOs, NFTs, and the Metaverse. Notably, these concepts have already materialized through various services, such as NFT marketplaces, games, and browsers.
Considering that the internet, which many individuals perceive as indispensable today, has only existed for approximately 20 years, the potential transformations that lie ahead are undoubtedly captivating. The evolution of Web 3.0 will undoubtedly shape the future of our online experiences.
Conclusion:
Web 3.0, the decentralized internet driven by blockchain, offers significant advantages like personal data control, reduced information leakage risks, and direct peer-to-peer transactions. With virtual currencies, NFTs, and the Metaverse as concrete examples, Web 3.0 showcases the potential for a transformative online future. Embrace the next-generation internet revolution and witness how it reshapes our digital landscape.
