Hahaha I also used to say sushi as long as it is a raw fish but I didn't know the difference between the two sushi and sashimi now I know hahaha. By the way yes it is hard to explained the blockchain and I don't fully comprehend it either, and it makes me smile reading that u can't really explained it even though u work at blockchain hahaha, I guess the simple explaining is "it's a free money"so that they will find interest then, hahaha. Thanks for sharing, steem on. :)
