How does Web3 differ from Web 2.0?

Web3 differs from Web 2.0 by shifting from centralized platforms and data ownership to decentralized, blockchain-based systems.

What are some challenges and risks associated with Web3 adoption?

Web3 faces challenges such as scalability, energy consumption (in the case of some blockchains), and regulatory concerns.

Can Web3 be applied to industries beyond cryptocurrency and finance?

Yes, Web3 has applications in various industries, including healthcare, supply chain management, and voting systems.

When will I have access to the lectures and assignments?

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

What will I get if I purchase the Certificate?

When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.

Is financial aid available?

Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
