The term Web3 has appeared as a revolutionary force that is reshaping the digital world by promising a decentralized, user-owned internet. Based on blockchain technology, Web3 strives to eliminate middlemen, give users ownership of their information, and make digital interactions transparent. Nevertheless, despite the exciting vision, the path towards mainstream adoption is fraught with mammoth challenges. The development and implementation of Web3 technologies are faced with technical, legislative, and social challenges that can restrict their long-term potential. It is vital to overcome these challenges if Web3 is to transition from a trial environment into a functional, scalable, and secure foundation for the next era of the internet.
