I've been reading up on Hashgraph in the last few weeks. The tech promises to be very interesting, solving the current scalability challenges we have with blockchain. That, while still providing the security needed through their Asynchronous Byzantine Fault Tolerant consensus mechanism.

It is however very closed and private (permissioned network) so far. We first need to see this in the real world with real challenges. I believe also the 'swirlds' tech is patented.

So to me it feels very 'corporate'. Even though it sounds interesting, I somehow don't like it because of that :-P

I will keep a close eye on the project and we'll see where it goes.
