Experiment: Saving a .pdf with proofofexistence.com

My blog is on "Hiatus", and for at least a while to be only used for my idiosyncratic uses...

The below experiment is sending a hash of a .pdf file (two pages) for permanent placement on the blockchain.

Remarks:

1)  Yes, proofofexistence waits for a confirmation...  This takes an average of 10 minutes.  It can take quite a bit longer (and is in this case, this block took 40 minutes to be found).

2)  Yes, proofofexistence confirms my hashed document is now on the blockchain successfully encrypted, placed and hash number confirmed.
