When asked what technology has changed the world the most in recent decades, most people would answer "the Internet." We call the earliest form of the Internet Web1.0 or Web1.
Just as there are differences between Web2.0 and Web3.0, one might naturally think there would be differences between Web1.0 and Web2.0. However, surprisingly, there is no clear distinction between them. These are not official terms.
Generally speaking, Web1.0 refers to a much less commercialized form of the Internet. For example, advertisements were very rare on the Internet during the Web1.0 era, and even when they existed, they were prohibited on many websites. The Internet consisted mostly of static pages running on web servers hosted by ISPs.
Information was mostly provided unilaterally. Even if there was incorrect information, it was very difficult to correct it, and website design changes were also quite limited. During the Web 1.0 era, websites were typically created as read-only platforms.
The Web1.0 era allowed almost no participation from ordinary users. Regular users could only consume the content on web pages. For instance, there were no wiki-style web pages like Wikipedia, which has become very common today and encourages public participation in content creation. While personal blogs existed, the types of content users could add were generally limited.
Naturally, the applications used in Web1.0 were not open either. Users couldn't look into how these programs worked or change detailed options. Source code was rarely made public. This closed nature of Web1.0 significantly restricted innovation and user empowerment, creating a one-way communication model where content creators held all the power and users remained passive consumers.
Web 2.0 or Web2 is a term that began to be used in the early 2000s during the "dot-com bubble" era. It was coined to signify a transition to a more sophisticated Internet compared to the past.
Starting with Web 2.0, companies began entering the Internet world. As they generated revenue, many users started interacting with platforms. More users began entering the Internet world, creating a dynamic ecosystem of content creation and consumption.
Companies providing Web2.0 services were proactive in reflecting users' voices. For example, on sites like Amazon, all users can add reviews to products listed on the site. Wikipedia also allowed all users to modify entries on their encyclopedia-like site. New social media platforms like Facebook and Twitter enabled people to interact much more in an open environment than previous platforms.
At the program level, the biggest change was the emergence of the "open source" spirit. Some Web2.0 companies made their source code public so users could modify and use their programs. Anyone with appropriate technical expertise could peek into, analyze, and modify already-created programs. This democratization of technology fostered innovation and collaboration, allowing developers worldwide to contribute to and improve existing platforms.
While there were several major advances in the transition from Web1.0 to Web2.0, disadvantages were also discovered.
As companies participated as major players on the Internet, people gained services that didn't exist before, but companies that dominated platforms gained the power to censor user communities. The power of social media service companies like Facebook and Twitter grew stronger in this regard.
Online payment services using the Internet also strengthened corporate power. Companies require users to comply with guidelines they set when transferring money online. If these are not followed, they can unilaterally refuse payment.
In summary, Web2.0 was a more advanced Internet with various better technologies applied compared to Web1.0. However, to fully utilize it, users had to follow a set of rules established by companies providing Web2.0 services. This means users became dependent on Web2.0 service companies, creating centralized control structures that often prioritized corporate interests over user autonomy.
From this perspective, Web3.0 can be easily understood. Web3.0 refers to a stronger, more secure, and decentralized form of the Internet. The direction of being technologically superior to Web2.0 while being less dependent on service companies would be Web3.0. The person known to have first used the term Web3.0 is Gavin Wood, co-founder of Ethereum, in 2014.
Usually, Web 3.0 is explained in connection with blockchain technology. However, blockchain is not essential for something to be Web3.0. If a decentralized environment can be maintained, it's sufficient to be called Web3.0.
Of course, in a broad sense, Web3.0 is also used in mainstream media to represent future Internet technology. You'll hear many stories about various companies preparing for the arrival of this new and improved Internet. However, it's essential to know that blockchain technology will play a tremendous role in how this is built.
Just as Web2.0 provided a higher level of sophistication compared to the static pages of Web1.0, Web3.0 should also be accompanied by some clear technological advances. However, these changes are not yet visibly apparent. This is because there are still stages remaining until commercialization.
Fragmentarily speaking, the main function of Web3.0 is owning and managing one's own data. Research is currently underway to create such an environment using blockchain technology. This fundamental shift in data ownership represents a paradigm change from the current model where large corporations control and monetize user data.
Web3.0 is also deeply connected to the metaverse. In the long term, advanced 3D graphics such as augmented reality and virtual reality will be used in Web3 applications, creating immersive digital experiences that blur the lines between physical and digital worlds.
Finally, an important point is that Web3.0 uses smart contract technology. This is an essential part of creating a trustless Internet. Smart contracts can greatly reduce the need for third-party intermediaries, enabling peer-to-peer transactions and interactions without centralized authority.
However, there are also aspects that could be lost due to the emergence of Web3.0. If a highly decentralized Internet is actually implemented, it will greatly affect the survival of existing big tech companies. They will have to pay for user data that they used almost for free in Web2.0.
Perhaps for this reason, representatives of some big tech companies have pessimistic attitudes toward Web3.0. Tesla founder Elon Musk has officially stated that "Web3.0 feels like a marketing gimmick." Former Twitter CEO Jack Dorsey also believes that the kind of decentralization represented by Web3.0 is impossible. Dorsey argues that big tech companies will not allow them to lose control over their current power.
For Web 3.0 to become a reality on a sufficient scale, much greater commercialization of blockchain technology will need to be achieved. What's hopeful in this regard is that technological development in the blockchain field has been happening at a very fast pace since 2021. If this situation continues, we will see some parts of the transition to Web3.0 become reality in the near future.
Having looked at the rough "big picture," let's now examine the major differences between Web3.0 and Web2.0.
In Web 3.0, decentralized networks ensure that individuals have control over their online data. This would mean the playing field becomes level. Basically, individuals will have control over their online data, and individuals who contributed to the operation of a specific network will be rewarded accordingly. This represents a fundamental shift in power dynamics, moving away from centralized corporate control toward distributed user ownership.
Privacy or personal information protection is an important concern for modern Internet users. Nevertheless, in recent years, there have been incidents where vast amounts of personal information were leaked from big tech companies. There are claims that Web3.0 will improve this situation and provide users with a higher level of privacy. This is because decentralized personal data storage can provide individuals with better control over their data, implementing cryptographic protection and user-controlled access permissions.
The use of smart contracts can create a trustless Internet. This means individuals don't need to make an effort to trust third-party actors. If transactions are conducted through smart contracts according to set code, fraud and defaults will be greatly reduced.
When blockchain and smart contracts become popular, the Internet will take on a permissionless character. Permissionlessness means that when I engage in any on-chain activity, I don't need anyone's permission. Currently, if a bank or government doesn't allow my transfer, I can't send money to others, but when the Internet becomes a permissionless world, I'll be able to buy things and send payments without seeking anyone's permission. This fundamental shift enables true financial sovereignty and eliminates gatekeepers from digital transactions.
Because Web3.0 is still in the early stages of development, it's not certain how it will proceed. Some aspects are certain, but other more hopeful goals, such as complete decentralization, will clearly not be implemented exactly as we dream. Compromise in realistic terms will be somewhat inevitable.
Nevertheless, it appears there will be significant changes in how we interact on the Internet within the next decade. This will be an exciting era overflowing with opportunities. As blockchain technology matures and more applications emerge, early adopters and participants in the Web3.0 ecosystem may find themselves at the forefront of a technological revolution that reshapes digital interaction, ownership, and value exchange.
Web3.0 enables users to own and control their data directly through decentralized systems, while Web2.0 relies on centralized platforms controlling user data. Web3.0 leverages blockchain technology to ensure true data sovereignty and user autonomy.
Web3.0 advantages: decentralization, user ownership of data and assets, transparency, and resistance to censorship. Disadvantages: technical complexity, slower transaction speed, scalability challenges, and regulatory uncertainty.
Decentralization in Web3.0 means no single entity controls the network. It is important because it enhances user privacy and control, eliminates single points of failure, and empowers users with ownership of their data and digital assets.
Blockchain serves as the foundation for Web3.0, enabling decentralized networks, data security, and trustless transactions through smart contracts. It ensures immutable records, user data sovereignty, and transparent operations without intermediaries.
Web2.0 centralizes data ownership in companies controlling servers. Web3.0 decentralizes ownership through blockchain, giving users direct control and sovereignty over their data. Users can independently manage and monetize their information.
Web3.0 applications span multiple domains: Decentralized Finance (DeFi) like Uniswap and MakerDAO enable peer-to-peer lending and trading; NFTs represent unique digital assets; Decentralized Autonomous Organizations (DAOs) enable community governance; platforms like Steemit offer decentralized social media; and Filecoin provides distributed storage solutions.
