On the Preliminary Investigation of Selfish Mining Strategy with Multiple Selfish Miners [article]

Tin Leelavimolsilp, Long Tran-Thanh, Sebastian Stein
2018 arXiv   pre-print
Although a theoretical analysis of selfish mining strategy under this setting is yet to be established, the current findings based on simulations is promising and of great interest.  ...  Moreover, there exist Nash equilibria where all selfish miners in the system do not change to an honest mining strategy and simultaneously earn their unfair amount of mining reward given that they equally  ...  On the contrary, miners in practical individually mine on their locally-stored blockchain and consequently create new blocks independently.  ...
