I'm seeing red flags all over the story. "Blockchain" being the first one. The use cases for that are so small, it is a red flag in and of itself. Then asking you to run code before a meeting? No, that doesn't "save time", that is driving you to take actions when you don't yet know who is asking.
Still, I appreciate the write-up. It is a great example of a clever attack, and I'm going to watch out more for such things having read this post.
