Rational Miner Behaviour, Protocol Stability, and Time Preference: an Austrian and Game-Theoretic Analysis of Bitcoin'S Incentive Environment

This paper integrates Austrian capital theory with repeated game theory to examine strategic miner behaviour under different institutional conditions in blockchain systems. It shows that when protocol rules are mutable, effective time preference rises, undermining rational long-term planning and...
