Really? Post a signature from the 5BTC reward wallet at least, it shouldn't be hard

Convince us by publishing the first message "z" in plain text, not only the hash of it...
My guess is that this has nothing to do with any quantum-resistant development! Prove me wrong!
Spectacular would be to see a signature from the wallet of the pubkey you published

Genius, trying to make others solve anything for you, but I doubt it will work!
My opinion is that you are interested only about the private key of: 0337cb099a32bdc5e3b790b0ad94a2c0d1184a1bba7a2b688223a183ff7bdbdf33
End of story: that could be in relation with your real target?!
!!! Thanks, but no thanks!!!
