General Discussion / Re: BitFury White Paper: "Proof of Stake versus Proof of Work"
« on: October 22, 2015, 04:13:18 pm »
Thanks a lot for the responses. Seems like BitFury already admits that BitShares is not vulnerable to most of the attacks they listed. So the BitFury report is very positive for the BitShares community from my perspective.
They say this about the Long Range Attack.
"In delegated PoS, an attack typically re-quires collusion by 2/3 of delegates"
Is this a risk for BitShares when 2/3 of witnesses collude then?
Can you provide more detail about TAPOS and how it prevents collusion?
Any comments/links relevant to the DOS and Sybil attacks?
