Theoretical attack against proof of stakeLong Range — Photo by William Daigneault on UnsplashFor my dedicated readers, I guess you already know what I’m about to say about long-range attacks … but if you need more convincing, read on.Long-range attacks are a popular reason to discredit proof of stake algorithms together with the concept of “Weak Subjectivity”. The idea is that at some point of time (most likely at the Genesis block), an attacker can use the existing state of the #blockchain, together with a significant stake of the token balance, to create a chain that is indistinguishable from the real chain. The attacker then tricks users into using his malicious chain instead of the real one.As I previously observed in my article about the “Nothing at Stake” attack, this seemingly simple attack (...)
