Is there a way to tell whether a minted block is from PoW or PoB?
muf18 has already answered, but if you want to go a little deeper to understand the Slimcoin blockchain, convert the block into JSON with your Slimcoin client and look at the "flags" parameter. It should give you one value from "proof-of-burn", "proof-of-stake" or "proof-of-work". That's where the nice flame symbol at ACME comes from ...
At ACME, you can see the JSON block structure if you select "Unprocessed JSON API response" at the bottom.
on this page http://slimco.in/proof-of-burn-eli5/ the word "unfamous" is used to describe a 51% attack when the correct word should be "infamous"
Will change that soon, thanks! I've written that guide, I'm not a native English speaker, so I hope you forgive me 
@muf18: Have you already investigated "Semantic UI" so we can see if its CSS can be combined with Jekyll? I've briefly looked at it and I think it would not be too difficult - maybe the menus are the most difficult thing to change. Or do you want to create a totally new site?
