Will the Blockchain Economy be powered by something totally different like IOTA Tangle or Hashgraph?
Excellent article from dailyfintech.com – that goes into some detail about the alternatives:
The case against IOTA is simple – maybe it is fast and cheap, but maybe it is not secure. In the social media age, fast and cheap ruled. The Facebook mantra – move fast and break things – guided thousands of startups. In the value exchange era, when real hard-earned assets change hands, the old enterprise mantra is “test, test and test again” and “it will be ready when it is ready”. Get it wrong in the social media age and a photo lands in the wrong place. Get it wrong in the value exchange era and criminal gangs will find ways to steal millions.

From the Hashgraph Summary…
Hashgraph looks like an enterprise technology solution. They have proprietary, patented technology. This is the opposite of the open source + speculative coin ICO method of financing (which is what IOTA uses). The proprietary, patented technology approach is perfectly suited to enterprise permissioned networks. That is a big market and Hashgraph is really an alternative to solutions such as Ripple or R3 or Hyperledger. One can imagine a big inter-enterprise network such as SWIFT looking at Hashgraph DAG as an alternative to enterprise Blockchain solutions.
