Course Content

Module 1: The Evolution of the Internet
The Internet's origins trace back to the Cold War era when the U.S. Department of Defense sought to create a resilient communication network. This led to the development of ARPANET in the 1960s, a precursor to the modern Internet. In the 1970s, scientists developed TCP/IP, the fundamental communication protocols that underpin the Internet. The 1980s saw the transition from ARPANET to the Internet as we know it, with the introduction of the Domain Name System (DNS) making it easier to navigate. The World Wide Web, invented by Tim Berners-Lee in 1989, revolutionized the Internet by introducing hypertext and URLs, making it accessible to the general public. The 1990s witnessed the explosive growth of the Internet, with the development of web browsers and the rise of e-commerce. The 2000s brought the social media revolution, connecting billions of people worldwide. Today, the Internet continues to evolve, with advancements in mobile technology, cloud computing, and the Internet of Things (IoT) shaping its future.

Module 2: Core Concepts of Web3
Web3 is the decentralized, next generation of the internet. It leverages blockchain for security and transparency, using cryptocurrencies and NFTs for digital ownership. Smart contracts automate agreements, while dApps offer decentralized services. DAOs allow community-led governance. Web3 aims to empower users with greater control over their data and digital identities, fostering a more open and equitable online environment.

Module 3: Applications and Challenges of a Decentralized Web
Decentralized web applications offer exciting possibilities, including censorship-resistant social media, secure digital identity management, and transparent supply chain tracking. However, challenges remain. Scalability is a major hurdle, as blockchains struggle to handle large transaction volumes. Security vulnerabilities in smart contracts can be exploited. User experience can be complex, requiring technical knowledge. Interoperability between different decentralized platforms is also an ongoing issue. Regulation and governance in a decentralized world present further complexities. Despite these challenges, the potential benefits of a decentralized web drive continued innovation and development.

Module 4: Smart Contracts
Smart contracts are self-executing agreements written in code and stored on a blockchain. They automatically enforce the 1 terms of a contract when predefined conditions are met, without the need for intermediaries. Think of them as digital vending machines: once you put in the correct amount (trigger the condition), you automatically receive the product (the agreed-upon outcome). This makes transactions more transparent, secure, and efficient.
