Topic: Rewrite the bitcoin blockchain with 100% hash power - page 2. (Read 1974 times)
...
I have seen a graph from Peter Wuille where he is showing how much time you need to rewrite the whole bitcoin blockchain if you would have 100% of the hashing power. For example currently you would need almost 1 year.
What would be the advantage to rewrite the blockchain? Why would someone be interested to rewrite the blockchain?

I think it would take much longer than 1 year.
I would have assumed at least 3 years of nonstop building.
Can you please provide the info/link your are referring to?
Most simply, someone could in theory do this in order to change past transactions.
In order to do this they would need 100% of new hash plus a lot more extra hash than
the Bitcoin network currently has, to first catch up to our chain, and then to over take our
chain. Obviously this would be malicious and would be extremely expensive for the attacking
chain builder. This would need to be done by a State actor. There are steps that could be taken
so that a majority of Bitcoin nodes will reject this purposeful malicious chain.
Nobody is going to 100% of the hashing power. Its like asking what if my grandmother was born with balls.
Maybe you should be asking yourself, how do you know she wasn't born with balls?

Yes, I know but it is more a theoretically question

Guys,

Thanks to all!
