Good teachers are rare, so when you find one, cherish him or her.
Anders Brownworth is an exemplar teacher. I found this tutorial by his hand on what constitutes a blockchain, and it is by far the best explanation of the concept(s) I have seen this far.
Anders breaks down the material for total newbies, explaining one concept at a time. You are taken from a hash, to a block, to a blockchain, to distribution, tokens, and a coinbase.
Great work Anders, and too good of a resource not to share!
Now, hold on to your hat, as you can access this blockchain application yourself and play around with the concepts like Anders does in the video.
