Bitcoin Q&A: Proof-of-work, Attacks, and ASICs
Channel: aantonop
Date: 2020-01-10

How does proof-of-work prevent 51% attacks? Can the attacker change the whole chain in a 51% attack? How often has a 51% attack occurred? Could a government agency reverse a transaction? Did Satoshi foresee ASICs and how competitive mining would be? Does China control Bitcoin mining? Should we change the proof-of-work to solve this?
