How does blockchain really work? I built an app to show you
A good and interesting explanation. Though, since it doesn't mention transactions at all, it might leave folk thinking, "So great, I've got a chain of hashes. How is that in any way a `coin`"? A Part 2 with that concept would be excellent.<p>Also, tiny nitpick, but `bc` is a common unix command, so maybe a different shortname would be better.
