Dear Derek,

I think that before standardising a new cryptographic scheme in IETF it
would be prudent to have it approved by CFRG first, I believe this
might even be a rule.

If I remember correctly, then the Hash-based signature proposals have gone
through some kind of an approval process. Has the CFRG approved WalnutDSA
too?

Regards,
Janos
