Great, indeed we had same idea, I don't see how it solve the hashes in
As Alice knows
H(1000000) = <random secret seed>).
If she need the hash to the first commitment she need to hash the random secret
seed 1000000 times. I think it is exactly the same problem as it is the exact
same idea said differently.
