No this idea isn't about proof of work. The idea is delaying the
computation result, preventing a miner from picking a value.
If the computation takes an hour on the fastest available computer and
isn't parallelizable, then a miner can't influence
the unpredictable value (unless they have 51%).
With slightly weaker security requirements iterating only a few
million times would be decent as well, since attempting to
influence the value would result in a performance hit a competitive
miner can't afford.
