Bitcoin Researchers: You Can Game the System

Selfish miners gonna kill bitcoin , In USD we trust  Wink


How is it that they have no requirement to understand anything in the university concerning the topic they are researching...?

I was wondering if what they said was even possible. I never heard of hiding found blocks and the like.

While all miners work from the most recently discovered block (think of it as the "original" block), the selfish mining process begins when a pool of miners discovers a new block and doesn't publish it. The selfish pool then begins working on discovering yet another block, mining from this hidden one. Meanwhile, the rest of the "honest" miners are still wasting resources mining from the original block.

Can you mine FROM a "hidden" block? This makes no sense to me.
