Just a reminder, deleting from an app doesn't affect the blockchain.

I remember something about Etherscan, but I don't think you can delete transactions from there either. It’s all about transparency, right?

I thought you could delete transactions by contacting the Ethereum Foundation, but that seems too easy for a public blockchain.

I'm not entirely sure, but I feel like I saw a question about this in practice that mentioned something about the immutability of blockchain.

Option D stands out to me too. Accepting some ambiguity is part of the negotiation process; I remember practicing scenarios where that was crucial.

I feel like job significance could tie into how much responsibility CD wants, but I'm not sure if it directly supports development.
