This allows him to:
Reverse transactions that he sends while he's in control
---虽然别人愿意 confirm 这个 transaction, 但他会用自己的计算力阻止这个 tx 进入 block chain.
Prevent some or all transactions from gaining any confirmations
---可以用自己的计算力保证其他人无法在 block chain 上添加任何 transaction.
Prevent some or all other generators from getting any generations
---同上
The attacker can't:
Reverse other people's transactions
---虽然可以用逆转 block chain 的方法做到, 但代价是 60%+ 的计算力吧.
Prevent transactions from being sent at all (they'll show as 0/unconfirmed)
---其它的人还是愿意确认的
Change the number of coins generated per block
---这是基础
Create coins out of thin air
---有 difficulty 在
Send coins that never belonged to him
---公钥体系
