If you aren't sure what blockchain is, you’re not alone.

This technology only emerged over 10 years ago from a paper "Bitcoin: A Peer-to-Peer Electronic Cash System" written by Satoshi Nakamoto (or a person or persons using a pseudonym… the mystery continues). Is it all about Bitcoin? No. It’s more than all the cryptocurrencies.
