Hey, Steeve... I was wondering (being the geek that you are... lol) if you've done any research into Hash-Graph technology. It seems at first glance anyway, that the "Hashgraph" may well turn out to be superior to the blockchain. I don't know much about it beyond info contained in a documentary and this article I found - so I thought I'd pass them along to see what you thought... Thanks! https://steemit.com/cryptocurrency/@heiditravels/more-than-blockchains-how-hashgraph-and-dags-are-different
