Re: Good article
"I'm glad to hear they didn't approve proof-of-work. In this day and age, it shouldn't be on the table."
Maybe I'm missing something, but isn't proof of work as implemented in Bitcoin insanely computationally expensive because the algorithm increases the processing difficulty every time it starts becoming too easy? Is it possible to have a proof of work algorithm where the work proof needed to be done can be done in a reasonable non-planet melting computational time? Or does that then undermine the security?
