The progression that leads from the internet up until web 3.0 

For us to comprehend why Web 3.0 is widely regarded to be built on blockchain, let us first look at the internet’s historical trajectory. The global network started with Web 1.0 in the second half of the 1980s. This can be characterized as “read-only,” as users could see information but could scarcely interact. This period was revolutionary in its time, yet it had its constraints, primarily static resources with minimal user participation. 

Next came Web 2.0, which made the internet interactive. People for the first time could make profiles, upload content, post and share with people actively through Facebook and Twitter platforms.  

The Web 2.0 phase is characterized by the idea of content creation by users along with e-commerce growth. This enables people to purchase, sell, and share over the internet. Nevertheless, these abilities came with new challenges as companies started acquiring great user information.

Web 3.0, also referred to as the ‘decentralized web’, has a completely different narrative because control is said to change as people are provided ownership of their data. Here, the focus shifts to blockchain technology. This ensures data privacy and decentralization in ways that were never experienced before. 

The emergence of Web 3.0 and the role of blockchain platforms 

Web 3.0 has introduced a decentralized internet where users are more than just consumers since users can control their data and their digital identity. This vision promotes utilizing blockchain platforms like Ethereum as it brings understanding towards decentralization. 

Thanks to blockchain technology, information can be kept in numerous places (or nodes), thus making it decentralized and secure. More importantly, there is no need for database servers, which pose as single points of failure regarding system breaches.  

Last, but not least, there is a feature of blockchain for self-sovereign identities, and users can create and manage within their digital space without the need for an administrative body. 

Smart contracts are a good illustration of this phenomenon. In systems such as Ethereum, these contracts are executed automatically and facilitate interactions between unrelated parties without needing to trust. They came about in connection with applications using decentralized finance (DeFi) and non-fungible tokens (NFTs), where users can interact with each other without having a broker. 

Did You Know? 

In 2024, many sectors will likely gain rapid growth traction since they will begin to employ the features of blockchain applications within the scope of Web 3.0. 

Web 3.0 is the third stage of the internet, and this is how you interpret it: 

So, what is Web 3.0? In basic terms, it emphasizes making the internet more self-sustaining. Things like AI, IoT, and blockchain are used to make strides in ensuring privacy and security in online transactions. 

Web 2.0 was designed so that platforms could fill the role of a mediator in P2P transactions, but it also meant that platforms control most of the user information. The blockchain tackles this, providing a neutral structure where no entity is solely controlled. It solves problems of trust and privacy, which Web 2.0 could not address fully.  

As Web 3.0 is based on blockchain, it allows this interaction mode without any centralization, enabling new forms of applications. 

1. Web 3.0 technologies and applications: Web 3.0 introduces several new applications that are built to counteract some restrictions of Web 2.0: 

2. Decentralized social networks: In Web 3.0, no Facebook company owns social networks anymore. Instead, all users own their data, significantly reducing the problems of censorship and data exploitation witnessed on previous platforms. 

3. Decentralized finance (DeFi): By virtue of DeFi, even customers without the application of traditional banks can perform financial activities. Using blockchain technology, DeFi networks facilitate accessibility to financial services that allow lending, borrowing, and exchanging between users. 

4. Digital identity management: Companies apply this type of management to digital identities. This allows customers to manage their online imagery independently, thus reducing dependence on external platforms. Such practices of identity management are termed self-sovereign identity. 

5. Supply chain transparency: Machine learning can reduce cryptocurrency scams, in part, by more efficiently predicting fraud. 

6. Content and intellectual property: Blockchain facilitates transparency throughout the supply chain by providing a ledger of every transaction and contract involved. Companies can assure customers of the legitimacy of their products and the source of materials used in facilitating the production. 

The role of blockchain in Web 3.0 advancements 

Blockchain’s decentralization and security aspects are driving factors in Web 3.0. Blockchain protocols offer interoperability, allowing seamless exchange of data and assets across networks. This interconnected system provides an environment where information flows freely, supporting applications like smart cities and IoT networks. 

Consider a smart contract. It’s essentially a set of coded rules stored on a blockchain that automatically executes transactions when certain conditions are met. This creates a reliable framework for Web 3.0 applications where transactions happen securely without needing a central authority.

Practical applications: blockchain in Web 3.0 

Blockchain applications in Web 3.0 are vast. Here are a few areas where it’s making a significant impact: 

• Universal Identification: With the help of blockchain-based identities, there is no need to have third parties who manage sensitive data, thus increasing privacy. 

• Improved Security: It gets difficult for hackers to penetrate the database owing to the non-centralized system of the block chain. 

• Ownership Control: Through the use of block chains, users are able to directly own their data and any digital assets they may have. 

In addition, blockchain simplifies how organizations manage user identities. With blockchain, consumers can have a single digital ID that’s secure, private, and universally recognized across platforms. This not only reduces dependency on centralized entities but also strengthens privacy. 

Web 3.0: How blockchain made the future possible 

By offering a decentralized framework, blockchain technology made it possible to develop Web 3.0. It started with the blockchain of Bitcoin, which featured a P2P network whereby a single organization could not own all the data. This concept has expanded with protocols allowing for a consensus-driven data storage approach. 

Each participant on a blockchain network contributes to its security, incentivized by native tokens. This structure ensures that data is secure, transparent, and immutable. It is providing a base for the more complex applications of Web 3.0.
