About a year after Ittay Eyal published two papers claiming vulnerabilities in the bitcoin mining protocol, we have seen that the network is still strong (it has grown in hashpower many times over) and is unaffected by the supposed problems. I show here the biggest reasons the two vulnerability analyses were flawed. The attacks appear to hinder other miners who are competitors. However, both of the attacks harm the attacker's bottom line more than any harm to the competitors can emerge as profits for the attacker.
