| Jan 28, 2018 at 4:30 | comment | added | user31456 | To prevent damages from the first and second attack types - who is supposed to do the waiting for the confirmation? The recipient or the sender? Asking because it sounds like you are saying that the recipient can "prevent damages" by waiting but s/he is actually at the mercy of the sender in these situations. A malicious sender would certainly not be interested in waiting if the attack calls for something to be done in quick succession. | |

That is not particularly true, because if you own a lot of mining power, cost of attack becomes really small to you, so you can wreck a lot of people with little cost. Also, you don't need big money to do that. All you need is to hack one the biggest mining pools. | |

Finney attack named after a person, thus proper noun should be capitalized.
