Excellent must see video from Mike Maloney. HASHGRAPH = Interesting technology emerging to challenge BLOCKCHAIN.
Well I'm lost, there are a lot of gaps in his explanation. Maybe it just needs a better person to explain it. My understanding is this it not a proven working model for use as a crypto currency, otherwise it would be in use now. I remember thinking that iota would be the new method, but it turns out when having to keep track of hystory it doesn't work so good. So far the only proven method is the basic blockchain. But I hope and would be supper happy if the day comes when one of these other methods are proven to work better.
