alt Hacker NewsIf you mine a block without revealing it, not only are you the only one that can mine the next block after that, but everyone is mining on the "wrong head". There's of course the risk that someone finds a different head in the meantime, but otherwise, you waste competitors' resources, while you get an advantage on the next block.

They are not mining on the wrong head. They are mining on the current head. If they find a block it will be accepted as the new head and the withheld block will be rejected, so it's not wasted mining time at all.

What makes it more likely that your first block ends up the next head and you're not wasting your own time on the second one if someone beats you to the first one while you're holding off?
