Thanks for the link, that's the exact article that was published on Medium too, good to know that guy is on Steemit as well!
Later edit: I just saw the author of the Steemit article just copy pasted the initial author on Medium. He gave credit at the end of the article, but still... And he's on @cheetah's black list, probably... Quite sad to try to make a few cents off of the back of somebody who took hours to write that article and years to learn all the intricacies of blockchain programming to actually understand what's going on.
Thanks for the update. I would assume it was the Author of the article if it was not made quite clear it was a Copy N Paste job. A Very Naughty Boy!
Upvoting your edit. I was a professional freelance writer for over 15 years. Not a fan of plagiarism, and respect the people who do, as you say, take many hours to put together their published works.
