Hashgraph Developing a Public Ledger?

For those of you unfamiliar, Hashgraph is a distributed ledger like other crypto currencies and tokens, but does not utilize a blockchain. It offers a provable byzantine-fault tolerant method of ensuring synchronicity with very fast (and cheap) transactions. It's also been successfully used within the credit-union sector with great success, which shows considerably more real-world utility than many other projects that are out there. (Granted, this was in a closed environment with known nodes.)

I noticed they seem to be on the verge of making some sort of public announcement and have introduced a 'registration' form on their home-page. (https://hashgraph.com/)

Perhaps this is the introduction of an ICO for Hashgraph's public ledger/crypto currency?

If it is, this is one I intend to invest in. I think this technology has the potential to have enough performance and security to be a disruption in the crypto space, and perhaps gain wide-spread adoption by mainstreet.

I am curious what everyone else's thoughts on hashgraph are. Do you intend to invest if it is an ICO? Do you see this being a game changing technology?
