DESCRIPTION:We formulate and study the stochastic game of miners that parti
 cipate in the bitcoin protocol. We consider the possible beneficial deviat
 ions a miner can have: the simplest strategy is to release every mined blo
 ck immediately\, but be strategic on which blocks to mine. The second\, mo
 re complicated strategy\, is to withhold mined blocks so that the other mi
 ners cannot use them\, and release them in a misleading way. We show that 
 when the computational power of each miner is relatively small\, their bes
 t response matches the expected behaviour of the bitcoin designer\, leadin
 g to an efficient PNE. However\, when the computational power of a miner i
 s large\, he deviates from the expected behaviour and significantly improv
 es his payoffs. Bio Sketch: Philip Lazos graduated at University of Oxford
  in 2019 with a thesis on Online Market Algorithms under the supervision o
 f Elias Koustoiupias.  He is currently a postdoctoral researcher at Sapien
 za University of Rome supported by the ERC Advanced Grant Project Algorith
 mic and Mechanism Design Research in Online MArkets (AMDROMA)
