|
| If you want "nothing up my sleeve" numbers start with a source that
| has long been published and do a simple repeatable manipulation to it.
|
| For around 2^14 bits, I think you could take a long novel (say, the
| Gutenberg Press copy of Fyodor Dostoyevsky's book _The Idiot_).
|
| Separate it into sentences.
| Eliminate any duplicates.
| Take all combinations of two sentences in a deterministic sequence.
| Produce a SHA256 block for each.
|
| Then publish the code that munged the book into the bitblock,
| publish the exact version of the book you used, and everybody can
| verify that the bits you used are in fact derived from that book
| in a straightforward way and that you didn't manipulate the text
| to get any particularly-desired results.
Would you like to borrow my (first edition) copy of RAND's
_One Million Random Digits_, buy your own reprint ($60 USD),
or tell me what it is that I am missing here?
