Block witholding attacks are only possible if you have a majority of hashpower. If you only have 20% hashpower, you can't do this attack. Currently, this attack is only a theoretical attack, as the ones with all the hashpower today are not engaging in this behavior. Even if someone who had a lot of hashpower decided to pull off this attack, they wouldn't be able to disrupt much. Once that time comes, then I think this problem should be solved, until then it should be a low priority. There are more important things to work on in the meantime.
This is not true. For a pool with 5% total hash rate, an attacker only needs 0.5% of hash rate to sabotage 10% of their income. It's already enough to kill the pool _______________________________________________ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
