The Simplest Bitcoin Book Ever Written
Bitcoin is the great incentivizer.
"The incentive may help encourage nodes to stay honest. If a
greedy attacker is able to assemble more CPU proof-of-worker
than all the honest nodes, he would have to choose between using
it to defraud people by stealing back his payments, or using it
to generate new coins. He ought to find it more profitable to
play by the rules, such rules that favour him with more new
coins than everyone else combined, than to undermine the system
and the validity of his own wealth."
