A 51% attack can reliably undo any number of confirmations.
- stale2002 9y agoIt is not as easy as that would suggest. Sure, you can build a longer blockchain, but nothing forces other people to accept that blockchain. IE, people can checkpoint the chain. Also, if 51% attacks consistently started to happen, that would cause the price if that chain to plummet to 0. There is no point stealing money that is worth 0.
- AgentME 9y agoA 51% attack could be done by someone who hopes to dump their gains before the market reacts, or it could be done by someone who wants to see the value go to zero. Bitcoin Cash could start checkpointing itself, but at that point it'd be centralized and you're right that its value would probably go to zero.
