I think the answer of this puzzle is in the bitcoin white paper... i will try to brute force that.

brute forcing is not good way for solving this puzzle. assume the white paper has 100 distinct words, total number of combinations is: 100! / (100-8)! = 7.50306389818e+15 . assume you have a good computer and it can compute 1000 combinations per second, total time of computing will be: 7.50306389818e+12 seconds= 237920 years.

I had in mind another kind of brute force. What i did was:

Code:
a1=(words count in wp.txt)
a=(a1 - 8)
for b in (sequence 1 to $a)
do
take words from $b to $b+8, if the sum is 32 char then save it on a file
done

And what i get was this:
