If you only have 20% hashpower, you can't do this attack.\n\u003e Currently, this attack is only a theoretical attack, as the ones with\n\u003e all the hashpower today are not engaging in this behavior. Even if\n\u003e someone who had a lot of hashpower decided to pull off this attack,\n\u003e they wouldn't be able to disrupt much. Once that time comes, then I\n\u003e think this problem should be solved, until then it should be a low\n\u003e priority. There are more important things to work on in the meantime.\n\u003e \n\nThis is not true. For a pool with 5% total hash rate, an attacker only\nneeds 0.5% of hash rate to sabotage 10% of their income. It's already\nenough to kill the pool"}
