I have never heard of hashgraph. Thanks. I will check it out.

As far as transparency in a secret society ... I agree it is hard to justify sometimes. I like the fact that everything is public on the blockchain but that can also be bad for certain things. I would like if there was a way to keep things secret but I guess that goes against the technology. What ends up happening is people use third party sites to interact in secret to reduce exposure on the the blockchain. I believe this is how things will move forward in the future, at least for the time being.
