Metaverse & Web 3.0 | Science & Technology for UPSC CSE PDF Download

The Metaverse and Web 3.0 are transformative technologies reshaping the digital landscape. The Metaverse is a virtual, interconnected universe combining augmented reality (AR), virtual reality (VR), and digital environments, enabling immersive experiences in gaming, education, and commerce. Web 3.0 is the next evolution of the internet, built on blockchain, decentralization, and user ownership, fostering trustless and transparent systems. India, with over 900 million internet users and a thriving tech ecosystem, is adopting these technologies to drive innovation, financial inclusion, and global leadership. As of 2025, India’s digital economy contributes 10% to GDP, with the 2025-26 Union Budget allocating ₹1.5 lakh crore for digital infrastructure, including Metaverse and Web 3.0 initiatives.
