Web 2 and Web 3 are two different iterations of the World Wide Web. Web 2 is the version of the internet most of us know today, which is dominated by companies that provide services in exchange for personal data. Web 3, on the other hand, is an idea for a new iteration of the World Wide Web which incorporates concepts such as decentralization, blockchain technologies, and token-based economics. This means that Web 3 would be a much more secure, private, and decentralized version of the internet. It would be powered by blockchain technology, allowing users to participate without monetizing their personal data. Web 3 would also be more secure, as it would be able to protect user data from malicious actors and government surveillance. In addition, Web 3 would also be more transparent, as transactions would be recorded on a public ledger, making it difficult to hide nefarious activities. Ultimately, Web 3 would be a much more efficient, secure, and transparent version of the internet.
