This is really a follow up to my previous question which I think may have gotten loss in the comments.
Is there a security deposit required to put up for an accusation? What's the financial incentive to prevent people from accusing every block? It seems like there is big incentive to accuse every block - half of the safety deposit of the baker, which would be 512/2 = 256ꜩ is this correct? Am I missing something?
