  • The 2013 paper analyzes selfish mining, where miners gain more than their fair share.

  • Selfish mining is profitable over one-third of the network hashrate, with block propagation speed as a factor.

  • Findings show selfish mining's profitability threshold lies between 36% and 37% of the network hashrate.
