As the name suggests, Web3 is the third generation of the internet that combines evolving technologies, including blockchain, NFTs, digital avatars and more. According to Chris Dixon of venture capital firm a16z, Web3 combines the best of both worlds; the decentralised ethos of Web1 with the interaction of Web2.
While tech enthusiasts, entrepreneurs, governments and big tech companies are rolling in the Web3 hype, it is not an easy concept to learn. Yet, notwithstanding the complexity, Web3 has quickly become one of the most important skills to hone.
Web3 combines many blockchain-adjacent evolving technologies, including digital avatars, non-fungible tokens (NFTs) and decentralised applications. As with any influx of new technology, there’s a need for new skills and talent.
