Hi again.

What I meant is that the discussion helped me to understand Lyra a little
better: seriously, I could not explicitly see the DAG in our own security
analysis until I analyzed Catena more carefully and understood its design.
Now that I see the DAG, it is much easier to understand its limitations
and possible improvements.

The algorithm won't change a lot, though, and I doubt it will be much
similar to Catena or NoelKDF: no offense, their designs are great and
worth copying, but I still need to cheer for my own design or for me the
competition will not be as fun ;)

Marcos.
