How Does the Block Propagation Delay Factor into the Success of a Selfish Mining Strategy?
Block propagation delay is the time it takes for a newly mined block to travel across the network and be received by all nodes. A longer delay increases the window of opportunity for a selfish miner to find a block and extend their private chain before the honest network is aware of the new public block.
This delay makes it easier for the selfish miner to successfully execute the block-withholding and reveal strategy, thus boosting their success rate.
