Is any of the tenebrix / fairbrix whatever scrypt based block chains still in operation?

Hi!

I am considering developing a framework in which micro payments in bitcoin or similar will be used to mark messages in email and similar as "preferred", i.e. someone payed a small sum for you to read it, similar to sms messages and paper letters, but not that expensive.

The possibility of sending un-stamped messages will still exist, but if you put a stamp on your message, it will end up on the receivers "priority" folder or similar effectively allowing you to ignore spam or second-rate mail from that firm you haven't ordered from the last 10 years.
