Sure, absolutely. Followed you. Don't want to spam links here, but if you're really interested, I'm starting a series of articles on the topic here in steem (basically working on 2 out of 3 of my goals this way :) ). The goal is to have an entertaining guide into the world of blockchain and cryptography. Feel free to check it out, the next post should be there before the week's end, and will describe hash functions with a short fictional story set in the Library of Bable universe.
