Quiz: Blockchain Essentials - Question 1

Which of these items are examples of an asset?

Detailed Solution for Quiz: Blockchain Essentials - Question 1
Assets Examples

  • A car: A car is considered an asset because it has value and can be sold for a profit.

  • A mortgage: A mortgage is not an asset, it is a liability as it represents money owed to a lender.

  • A digital music file: A digital music file is not considered an asset in the traditional sense as it does not have tangible value.

  • All of the above: The correct answer is all of the above, as a car is an asset, a mortgage is a liability, and a digital music file is not typically considered an asset.


Detailed Explanation

Assets are resources or valuable items that have economic value. They can be owned or controlled to produce value and generate income. In the context of the given examples:



  • Car: A car can be considered an asset because it has a resale value and can be used to generate income through services like ride-sharing or rental.

  • Mortgage: A mortgage is a liability because it represents a debt owed to a lender for a property purchase. It does not have inherent value like an asset.

  • Digital music file: While a digital music file may have personal value, it is not typically considered an asset because it does not have a tangible market value like physical assets.


Understanding the distinction between assets and liabilities is important for financial planning and decision-making, as it helps individuals and businesses assess their financial health and make informed choices about investments and expenditures.

  • Privacy Services: Privacy services ensure that sensitive information is kept confidential and only accessible to authorized parties, protecting the integrity of the data on the blockchain.

  • Trust: Trust is a fundamental requirement for a business blockchain as it relies on the belief that the system is secure, reliable, and operates in the best interest of all participants.


These core requirements are essential for a business blockchain to operate efficiently and effectively, providing a secure and transparent platform for conducting business transactions.

Which of the following statements is false?

Detailed Solution for Quiz: Blockchain Essentials - Question 7
Explanation:

  • Blockchain adds a cognitive analytics capability to the asset supply chain: This statement is false. While blockchain can enhance transparency and efficiency in the supply chain by providing immutable records of transactions, it does not inherently add cognitive analytics capabilities.

  • Blockchain provides a smart contract feature that can be used to model assets of any description: This statement is true. Smart contracts are self-executing contracts with the terms of the agreement directly written into lines of code. They can be used to model various assets and automate processes.

  • Blockchain can help provide provenance for an asset: This statement is true. By recording each transaction on the blockchain, the provenance of an asset can be traced back to its origin, ensuring authenticity and reducing the risk of counterfeit goods.


Therefore, the false statement is B: Blockchain adds a cognitive analytics capability to the asset supply chain.
