Majority is not Enough: Bitcoin Mining is Vulnerable - arXi

Selfish mining poses two kinds of danger to the Bitcoin ecosystem: selfish miners reap disproportionate rewards, and the dynamics favor the growth of selfish mining pools towards a majority, in a snowball effect. The system would be immune to selfish mining if there were no pools above the threshold size. Yet, since the current protocol has no guaranteed lower bound on this threshold, it cannot automatically protect against selfish miners This attack can have significant consequences for Bitcoin: Rational miners will prefer to join the selfish miners, and the colluding group will increase in size until it becomes a majority. At this point, the Bitcoin system ceases to be a decentralized currency. Selfish mining is feasible for any group size of colluding miners. We pro-pose a practical modification to the Bitcoin protocol that protects against selfish mining pools that command less than 1/4 of the resources. This threshold is.
