The video explores decentralized applications (dApps), contrasting them with centralized ones like Facebook and Amazon. It highlights the benefits of dApps, such as enhanced privacy and autonomy, due to their open-source nature and blockchain-based operation. The video also discusses the technical aspects of dApps, including the use of cryptographic tokens and the absence of a single point of failure. An example of a decentralized ridesharing app is provided. The video concludes by addressing potential challenges in developing sustainable business models for dApps.

What is a key difference between centralized and decentralized applications?

• Centralized applications allow direct peer-to-peer interactions.

• Decentralized applications store data on a single server.

• Decentralized applications require a third party to route data.

• Centralized applications control data through a single server.

Which of the following is a cornerstone of decentralized applications?

• They must be closed source.

• They run autonomously based on open-source code.

• They operate on a private blockchain.

• They have a single point of failure.

In the example of the decentralized ridesharing app, what is the internal currency called?

• Uber Coin

• Zeus Token

• Ethereum

• Bitcoin

What is a potential challenge for decentralized applications in terms of business models?

• They can provide services free of charge without any issues.

• They can easily monetize user data.

• They might struggle to develop sustainable business models.

• They have unlimited access to user data.

What major benefit do decentralized applications offer compared to centralized ones?

• They require users to share personal data with third parties.

• They ensure data is controlled by a single entity.

• They operate on a private blockchain.

• They cut out third parties from data exchange, enhancing privacy.
