Wait, why would a family filter need blockchain? Seems overkill.

Totally agree, email data doesn't need decentralization.

I’m leaning towards the email campaign service too, but I’m not completely confident. It could be that the wifi router scenario is also not a good fit for blockchain.

I practiced a similar question where we had to evaluate the need for decentralization. I feel like the family filter wifi router scenario doesn’t really need blockchain either.

I think the email campaign service might not need blockchain since it’s more about sending messages than securing data. That seems like a good candidate.

I remember discussing how blockchain is best for scenarios requiring transparency and immutability, but I’m not sure which one fits that least here.
