tl;dr: younger coins have fewer miners, so they are more susceptible to 51% attack. In particular BCash has same hash function as BTC, so those BTC miners could easily switch into mining BCash, and so is even more at risk.
- oh_sigh 9y agoIt would incur a huge opportunity cost for them to switch over, especially because they would tank bcash by doing it.
- em3rgent0rdr 9y agoYes it would. This article is surprisingly ignorant of past discussion of the %51 attack.
- moduspol 9y agoIt also fails to account for the possibility that Bitcoin Cash becomes more valuable, and then Bitcoin is the "vulnerable" chain. It also doesn't mention the name of the author, and the HN user who posted this was created two hours ago. HNers should understand there is a huge political divide in the Bitcoin community right now on this very subject. Anonymous write-ups of known attack vectors framed as genuine warnings are nothing more than unsubstantiated fear, uncertainty, and doubt.
