Consider the following scenario: Due to consistent inaccuracies and outdated real estate listings, a residential real estate company wants to build a blockchain solution that accurately depicts which homes (assets) are available for purchase across all countries/provinces. All available homes should be publicly viewable by the general consumer audience, but certain details of the home, such as history of maintenance, should only be viewable by licensed real estate professionals.

Which architecture would best solve the product need?

APublic data hosted on a public blockchain, Privileged data security hoisted on a private database

BThe entire solution built on a private blockchain with proper permissions for both public and privileged data

CPublic and privileged data on hybrid blockchain will Proof of Stake consensus

DPublic data hosted on a public blockchain; Privileged data hosted on a private blockchain

Isn't a private blockchain just limiting access too much?

I think option A could work, but I worry about the security of the privileged data. We discussed how important it is to keep sensitive information safe in our last class.

I’m a bit confused about whether a hybrid blockchain would really meet the needs here. I thought public access was crucial, but I’m not sure how that fits with the need for restricted data.

This reminds me of a practice question we did about data privacy in blockchain. I think option D might be the right choice since it separates public and privileged data effectively.

I remember studying the differences between public and private blockchains, but I'm not sure which architecture would be best for this scenario.

Option D looks like the best fit to me. Separating the public and privileged data onto different blockchains makes the most sense for this use case.

This looks straightforward. The average number of defects is given as 21.6, so I just need to plug that into the formula and calculate the upper control limit. I'm confident I can get the right answer.

Option D for sure. Letting the public see the available homes while keeping the maintenance history private is a smart move. Blockchain for the win!

Ah, the age-old public vs. private blockchain debate. I'd go with D, just to avoid any 'blockchain inception' with a private blockchain inside a public one.

Hmm, I think option D makes the most sense. Keeping the public data on a public blockchain ensures transparency, while the privileged data on a private blockchain maintains security for the real estate professionals.
