After having dealt intensively with the beginnings of the internet, the unexpected growth spurt of social media, and the emergence of user-generated content in the context of Web 2.0 in previous chapters, including the related issues surrounding data protection and security, we now turn our attention to the internet of the future. This new age of the internet is generally known as Web 3.0. In particular, we will consider the possible role of blockchain technologies, which could prove to be a central pillar of this emerging web.
The Internet is in constant evolution, driven by increasing networking and digital integration. Web 3.0, often also referred to as the Internet of services and „things“, marks the next evolutionary step in this steady development. It promises to make the web smarter, more context-aware, and more personalized, by employing advanced technologies such as Artificial Intelligence (AI) and Machine Learning (ML). This future web is the next iteration of the World Wide Web, integrating concepts like decentralization, the use of blockchain technologies, and a token-based economy. Compared to earlier versions, it represents a significant evolution.
Web 1.0, which existed from around 1989 to 2004, consisted mainly of static web pages. Users in this phase of the internet were primarily consumers and not producers of content. In contrast, Web 2.0 is based on the idea of the „platform“ and puts a focus on user-generated content, which is uploaded and shared on forums, social media and network services, blogs, and wikis.
Unlike Web 1.0 and Web 2.0, Web 3.0 is characterized by a decentralized approach. Instead of centralizing data and content in a small group of companies, Web 3.0 strives for greater decentralization and democratization of the internet.
In this context, the role of blockchain technology is crucial. Originally made popular by cryptocurrencies like Bitcoin and Ethereum, blockchain provides a decentralized, transparent, and secure method of recording transactions. However, in Web 3.0, blockchain technology is used far beyond financial applications. For example, the Ethereum blockchain is a platform for executing smart contracts, which enable the creation of decentralized applications (dApps). The Web3 Foundation is actively promoting the development and promotion of Web3 technologies. It aims to foster innovative applications for decentralized web software protocols. It believes in an internet where users own their own data, where global digital transactions are secure, and where the exchange of information and value on the internet is decentralized.
While the idea of Web 3.0 fascinates many people, the question remains open as to how this vision can be implemented in practice and what impact it will have on the internet as we know it today. Although some critics argue that the hype around Web 3.0 is exaggerated and the underlying technologies are not yet fully mature, there is no doubt that discussions about the future of the internet and the potential role that blockchain technologies could play in it are far from over.
