QUESTION 10 OF 26

What are the three main types of blockchains?

As the interview progresses, you will be asked questions that seem similar to ones you've previously answered. This is why active listening is a key skill you need to develop to be successful during an interview. Actively listening to the question you are being asked and not formulating your answer until the interviewer has finished asking their questions will ensure that you understand what you are being asked and the type of information the interviewer is requesting. While this question seems similar to something you were already asked, it is actually quite different.

"While the types of information maintained in a blockchain can vary greatly, there are only three types of blockchains. These are a public blockchain, a private blockchain, and a federated blockchain. A public blockchain is one in which there is no central authority, and anybody can read, write, or audit the Blockchain. This is typical of a cryptocurrency. A private blockchain uses the same technology but is limited to a specific individual or organization. A Federated blockchain is a hybrid of the previous two, allowing multiple people or organizations access to the information but only if they are invited to participate in the Blockchain."
