How Web 2.0 and Web 3.0 Differ

What Is Web 1.0

When asked about the technology that has changed the world most significantly over the past few decades, most people would answer "the Internet." The earliest version of the Internet is what we call Web 1.0 or Web 1.

Just as there are differences between Web 2.0 and Web 3.0, naturally there are also differences between Web 1.0 and Web 2.0. However, surprisingly, there is no clear distinction between these two. These terms are not actually official terminology.

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

Information was mostly provided in a one-way manner. 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, meaning users could only consume content without the ability to interact or contribute.

Disadvantages of Web 1.0

The Web 1.0 era was characterized by minimal participation from general users. Ordinary users could only consume the content on web pages without any meaningful interaction or contribution capabilities.

For instance, wiki-style web pages like Wikipedia, which encourage public participation in content creation and are now very common, did not exist during this period. While personal blogs existed, the types of content users could add were generally limited, and there was no mechanism for collaborative editing or community-driven content development.

Naturally, the applications used in Web 1.0 were not open to the public. Users could not see how these programs worked internally, nor could they modify detailed options or settings. Source code was rarely disclosed, making it impossible for users to understand, analyze, or improve the underlying technology.

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. It was coined to signify the transition to a more sophisticated Internet compared to the past, representing a fundamental shift in how people interacted with online platforms.

Starting with Web 2.0, companies began entering the Internet world in significant numbers. As these companies sought to generate revenue, many users began interacting with platforms in new and dynamic ways. This period saw an exponential increase in the number of users entering the Internet ecosystem, transforming it from a static information repository into an interactive, user-driven environment.

Use Cases and Examples

Companies providing Web 2.0 services were proactive in reflecting users' voices and feedback. For example, sites like Amazon allowed all users to add reviews to products listed on the site, creating a community-driven evaluation system. Wikipedia also permitted all users to change entries in their encyclopedia-like site, democratizing knowledge creation. New social media platforms such as Facebook and Twitter enabled people to interact far more extensively in an open environment than previous platforms, fostering unprecedented levels of social connectivity and information sharing.

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 according to their needs. Anyone with appropriate technical expertise could examine, analyze, and modify already-created programs, leading to rapid innovation and collaborative development across the Internet ecosystem.

Disadvantages of Web 2.0

While there were several major developments in the transition from Web 1.0 to Web 2.0, some disadvantages were also discovered that raised concerns about the future of Internet freedom and user autonomy.

As companies became major players on the Internet, people gained access to services that did not exist before. However, this also meant that companies controlling platforms gained the power to censor user communities in ways that were previously impossible. Social media service companies like Facebook and Twitter have seen this power grow increasingly stronger over time, raising questions about free speech and content moderation.

Online payment services using the Internet also strengthened corporate power significantly. Companies require users to comply with guidelines they have set when making Internet transfers. If these guidelines are not followed, they can unilaterally refuse payment, effectively controlling users' financial transactions without meaningful oversight or appeal processes.

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, sacrificing a degree of autonomy in exchange for convenience and functionality.

What Is Web 3.0

From this perspective, Web 3.0 can be easily understood as the next evolutionary step. Web 3.0 refers to a stronger, more secure, and decentralized form of the Internet. It aims to be technologically superior to Web 2.0 while being less dependent on service companies, representing a fundamental shift in power dynamics online. The person who first used the term Web 3.0 is known to be Gavin Wood, co-founder of Ethereum, who coined it in 2014.

Usually, Web 3.0 is explained in connection with blockchain technology, as this technology provides the foundational infrastructure for decentralization. However, blockchain is not absolutely necessary for something to be Web 3.0. As long as a decentralized environment can be maintained through other means, it is sufficient to be called Web 3.0, though blockchain remains the most prominent enabler of this vision.

Of course, in a broader sense, Web 3.0 is also used in mainstream media to represent future Internet technology and the next generation of online experiences. You will hear many stories about various companies preparing for the advent of this new and improved Internet. However, it is important to know that blockchain technology will play a tremendous role in the way this infrastructure is built, serving as the backbone 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 should also be accompanied by some clear technological advancements. However, these changes have not yet become visibly apparent, as there are still stages remaining before commercialization and widespread adoption.

From a fragmented 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, enabling users to maintain control over their digital identities and personal information without relying on centralized intermediaries.

Web 3.0 is also deeply related to the metaverse concept. In the long term, advanced 3D graphics such as augmented reality and virtual reality will be used in Web 3.0 applications, creating immersive digital experiences that blur the lines between physical and virtual worlds.

Finally, an important point is that Web 3.0 uses smart contract technology. This is an essential part of creating a trustless Internet that operates based on code rather than human intermediaries. Smart contracts can greatly reduce the need for third-party intermediaries, automating transactions and agreements in a transparent and verifiable manner.

Can Web 3.0 Succeed

However, there are also aspects that could be lost with the emergence of Web 3.0, particularly for existing power structures. 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 have been using almost for free in Web 2.0, fundamentally changing their business models.

Perhaps for this reason, representatives of some big tech companies 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 the type of decentralization represented by Web 3.0 is impossible. Dorsey argues that big tech companies will not allow themselves to lose control over their current power, suggesting that true decentralization may face significant resistance from established players.

For Web 3.0 to become a reality on a sufficient scale, much greater commercialization of blockchain technology will need to take place. What is hopeful in this regard is that technological development in the blockchain field has been progressing at a very fast pace since 2021. If this situation continues, we will see some aspects of the transition to 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's examine the main 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 means the playing field will be leveled, creating a more equitable digital ecosystem. Basically, individuals will have control over their online data, and those who contribute to the operation of a particular network will be rewarded accordingly, creating new economic models based on participation and contribution.

Privacy

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, eroding user trust. There is an argument 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 massive data breaches and unauthorized access.

Trustlessness and Permissionlessness

The use of smart contracts can create a trustless Internet, fundamentally changing how transactions and agreements are executed online. This means that individuals do not need to make an effort to trust third-party actors, as the code itself enforces agreements automatically. If transactions are made with smart contracts according to set code, fraud and default will be greatly reduced, creating a more secure and reliable digital environment.

When blockchain and smart contracts become popularized, the Internet will take on a permissionless nature. 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 allow my transfer, I cannot send money to others. However, when the Internet becomes a permissionless world, I will be able to buy things and send payments without seeking anyone's permission, creating true financial sovereignty.

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

Web 3.0 is still in the early stages of development, so it is not certain how it will proceed. Some aspects are certain, but other more hopeful goals, such as complete decentralization, will certainly not be implemented exactly as we dream. Compromises in practical aspects will be somewhat inevitable as the technology matures and faces real-world constraints.

Nevertheless, it appears that there will be significant changes in the way we interact on the Internet within the next decade. This will be an exciting era full of opportunities for those who are prepared to embrace these transformative technologies and adapt to new paradigms of digital interaction.
