How Web 2.0 and Web 3.0 Differ: A Comprehensive Analysis

What is Web 1.0

When asked about the technology that has transformed the world most significantly over recent decades, most people would answer "the Internet." The earliest form of the Internet is what we call Web 1.0 or Web 1. This initial iteration of the web laid the foundation for the digital revolution that would follow.

Just as there are differences between Web 2.0 and Web 3.0, naturally there are distinctions between Web 1.0 and Web 2.0. However, surprisingly, there is no clear-cut boundary between these two phases. These terms are not official designations but rather conceptual frameworks used to describe the evolution of the Internet.

Generally speaking, Web 1.0 refers to a much less commercialized form of the Internet. For instance, during the Web 1.0 era, advertisements were extremely rare on the Internet, and even when they existed, many websites prohibited them. The Internet consisted mostly of static pages that ran on web servers hosted by Internet Service Providers (ISPs).

Information was predominantly provided in a one-way manner. Even if there was incorrect information, it was very difficult to correct it, and website design was also quite limited in terms of modifications. Websites in the Web 1.0 era were typically created as read-only platforms, with minimal interactive features.

Disadvantages of Web 1.0

The Web 1.0 era was characterized by minimal participation from regular users. Ordinary users could only consume the content available on web pages, with little to no ability to contribute or interact. This limitation significantly restricted the potential of the Internet as a collaborative platform.

For example, there were no wiki-style web pages like Wikipedia, which has become commonplace today and encourages public participation in content creation. While personal blogs existed, the types of content users could add were generally limited. The lack of interactive features meant that users were passive consumers rather than active contributors.

Naturally, the applications used in Web 1.0 were not open to the public. Users could not see how these programs worked or modify detailed options. Source code was rarely disclosed, creating a barrier between developers and users. This closed approach limited innovation and prevented the collaborative development that would later characterize Web 2.0 and Web 3.0.

What is Web 2.0

Web 2.0, or Web 2, is a term that began to be used in the early 2000s during the "dot-com bubble" era. The naming was chosen to signify a transition to a more sophisticated Internet compared to the past. This evolution marked a significant shift in how people interacted with online content and services.

From Web 2.0 onwards, companies began entering the Internet world. As these companies generated revenue, many users started interacting with platforms in new and meaningful ways. More and more users began entering the Internet world, creating a vibrant ecosystem of content creators and consumers.

Use Cases and Examples

Companies providing Web 2.0 services were proactive in reflecting users' voices. For instance, on sites like a major e-commerce platform, all users can add reviews to products listed on the site. Wikipedia also allowed all users to modify entries in their encyclopedia-like site, democratizing knowledge creation. New social media platforms like Facebook and Twitter enabled people to interact much more in an open environment than previous platforms, fostering global conversations and connections.

From a programming perspective, the biggest change was the emergence of the "open source" spirit. Some Web 2.0 companies disclosed their source code so that users could modify and use their programs. Anyone with appropriate technical expertise could examine, analyze, and modify already-made programs. This transparency accelerated innovation and allowed developers worldwide to collaborate on improving existing technologies.

Disadvantages of Web 2.0

While there were several major advances in the transition from Web 1.0 to Web 2.0, some disadvantages were also discovered. The evolution brought new challenges that would later inspire the development of Web 3.0.

As companies participated as major players on the Internet, people gained access to services that did not exist before. However, companies that dominated platforms gained the power to censor user communities in ways that were not possible previously. Social media service companies like Facebook and Twitter saw their power grow increasingly stronger in this regard.

Online payment services using the Internet also strengthened corporate power. Companies require users to comply with guidelines they have set when transferring money online. If these guidelines are not followed, they can unilaterally refuse payment, creating potential issues for users who may find themselves locked out of financial services.

In summary, Web 2.0 was a more advanced Internet with various better technologies applied compared to Web 1.0. However, to fully utilize it, users had to follow a set of rules established by companies providing Web 2.0 services. This means that users became dependent on Web 2.0 service companies, creating concerns about centralized control and data ownership.

What is Web 3.0

From this perspective, Web 3.0 can be easily understood. Web 3.0 refers to a stronger, more secure, and decentralized form of the Internet. The direction of Web 3.0 is to be technically superior to Web 2.0 while being less dependent on service companies. The person who first used the term Web 3.0 is known to be Gavin Wood, co-founder of Ethereum, in 2014. This origin in the blockchain community has significantly influenced the development direction of Web 3.0.

Usually, Web 3.0 is explained in connection with blockchain technology. However, blockchain is not necessarily required for something to be Web 3.0. If a decentralized environment can be maintained, it is sufficient to be called Web 3.0. The key principle is decentralization, regardless of the specific technology used to achieve it.

Of course, in a broad sense, Web 3.0 is also used in mainstream media to represent future Internet technology. You will hear many stories about various companies preparing for the arrival of this new and improved Internet. However, it is essential to know that blockchain technology will play a tremendous role in the way this is built, as it provides the infrastructure for decentralized applications and services.

Characteristics of Web 3.0

Just as Web 2.0 provided a higher level of sophistication compared to the static pages of Web 1.0, Web 3.0 must also be accompanied by some clear technological advances. However, these changes have not yet become visibly apparent, as there are still stages remaining until commercialization.

From a fragmentary perspective, the main function of Web 3.0 is to own and manage one's own data. In recent years, research has been conducted to create such an environment using blockchain technology. This shift represents a fundamental change in how personal data is stored and controlled.

Web 3.0 is also deeply related to the metaverse. In the long term, advanced 3D graphics such as augmented reality and virtual reality will be used in Web 3.0 applications. These immersive technologies will create new ways for users to interact with digital content and each other.

Finally, an important point is that Web 3.0 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 traditional gatekeepers.

Can Web 3.0 Succeed

However, there are also aspects that could be lost due to the emergence of Web 3.0. If a high level of decentralized Internet is actually implemented, it will have a significant impact on the survival of existing big tech companies. They will have to pay for user data that they used almost for free in Web 2.0, fundamentally changing their business models.

Perhaps for this reason, some big tech company representatives have a pessimistic attitude toward Web 3.0. Tesla founder Elon Musk has officially stated that "Web 3.0 feels like a marketing gimmick." Former Twitter CEO Jack Dorsey also believes that decentralization in the manner represented by Web 3.0 is impossible. Dorsey argues that big tech companies will not allow themselves to lose control over their current power.

For Web 3.0 to be realized on a sufficient scale, much greater commercialization of blockchain technology must be achieved. What is hopeful in this regard is that technological development in the blockchain field has been occurring at a very fast pace since 2021. If this situation continues, we will see some of the changes toward Web 3.0 become reality in the near future.

Web 2.0 vs Web 3.0: Key Differences

Now that we have looked at the rough "big picture," let us examine the key differences between Web 3.0 and Web 2.0 in more detail.

Decentralization

In Web 3.0, decentralized networks ensure that individuals have control over their online data. This will mean the playing field becomes level. Basically, individuals will have control over their online data, and individuals who contribute to the operation of a specific network will be rewarded accordingly. This represents a fundamental shift from the centralized model of Web 2.0.

Privacy (Personal Information Protection)

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 Web 3.0 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, reducing the risk of large-scale breaches.

Trustlessness and Permissionlessness

The use of smart contracts can create a trustless Internet. This means that individuals do not need to make efforts to trust third-party actors. If transactions are made with smart contracts according to established code, fraud and defaults will be greatly reduced. The code itself becomes the arbiter of transactions, eliminating the need for trusted intermediaries.

If blockchain and smart contracts become popularized, the Internet will take on the character of permissionlessness. Permissionlessness means that when I do any on-chain activity, I do not need anyone's permission. Currently, if a bank or government does not permit my remittance, I cannot send money to another person. However, if the Internet becomes a permissionless world, I will be able to buy things and send payments without seeking anyone's permission.

Web 3.0 is a New Era of the Internet: Should We Prepare

Web 3.0 is still in its early stages of development, so it is not certain how it will proceed. Some points are certain, but other more hopeful goals, such as complete decentralization, will certainly not be implemented exactly as we dream. Some compromise in realistic terms will be inevitable.

Nevertheless, it appears that 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 continues to mature and more applications are developed, we can expect to see gradual adoption of Web 3.0 principles across various sectors of the digital economy.
