(just a note for myself: this thing you've been supposed to work on should be done by the time this pok gets unsealed) (this is also a test to see if poks could make sense as a way to set up deadlines for oneself)
A pok's hash
is a fingerprint of the pok content.
A specific text will always have the same fingerprint.
It is however impossible to guess the pok content from it.
sha1, sha256 and sha512 are different algorithms used to compute the hashes below.
The hashes were published as soon as the pok got created, proving that the author hasn't altered the text content in between.
