I did not say it was successful, quite the opposite, they drove people away with their extremism

https://handshake.org is the only good use case I know of, but their success is still widely unknown. It largely depends on how they play with ICANN

I also understand that Hyperledger is having some success, but the cryptokiddies really don't like that (realistic) implementation.

The biggest issue with blockchain projects is that they want to create some new order rather than participating in the existing society, and by doing so, artificially limit themselves.
