Hi guys, like many of you here I'm interested in cryptocurrencies, so i'm constantly trying to better understand the technology that powers this revolution - the famous Blockchain.
I had a rough idea before, but i couldn't really understand how it works under the hood. While searching online for information on this subject, i came across this awesome YouTube video bellow, which i think is by far the best explanation of what a blockchain is and how it all works.
