Web3 is the next evolution of the internet—one that aims to return control to users by leveraging blockchain technology and cryptocurrencies. Unlike Web2, where data and platforms are controlled by tech giants, Web3 envisions a decentralized web where users own their identities, content, and digital assets. In this ecosystem, cryptocurrencies serve as the native payment layer, enabling peer-to-peer interactions, decentralized applications (dApps), and new economic models like token-based governance and play-to-earn systems. Projects such as IPFS, Ethereum, and Polkadot are laying the infrastructure for this shift, challenging the centralized status quo. While Web3 is still in its early stages and faces technical, regulatory, and scalability challenges, its core philosophy—user empowerment, transparency, and decentralization—could redefine how we interact online in the years to come.
