Web3 is taking the world by storm. Often referred to as the next generation of the internet, Web3 aims to decentralize apps and websites by using blockchain technology. This shift towards decentralization and peer-to-peer connectivity has opened up many new career opportunities.
As per LinkedIn‘s 2022 Emerging Jobs report, demand for blockchain developers and engineers has grown over 600% since 2015. Web3 skills are becoming extremely valuable in fields like software development, product design and even digital content creation.
So if you want to future-proof your career, now is the time to skill up on Web3. This guide covers the best online courses and free resources to help you get started.
What Exactly is Web3?
Before diving into Web3 resources, let‘s quickly go over what it is.
Web3 refers to the third generation of internet services built using decentralized protocols like blockchain and crypto-economics. Some key aspects of Web3 include:
- Decentralization: Instead of data and apps being controlled by individual companies, control is distributed among users.
- Transparency: Records are public and transactions can be viewed by all participants.
- Privacy: Users have greater control over their data.
- Trust: Dependence on third-party intermediaries is reduced.
- Openness: Anyone can participate without permission.
Web3 will enable a range of innovative use cases across finance, gaming, social media, identity management and more. Developers skilled in Web3 will be critical for turning these ideas into reality.
