Definition ∞ A game theory mechanism refers to the design of rules and incentives within a system to encourage participants to act in a way that benefits the collective, even when pursuing their individual self-interest. It applies principles from game theory to predict and influence behavior in strategic interactions. In digital systems, these mechanisms often involve rewards for honest participation and penalties for malicious actions, ensuring system stability. This approach is fundamental to secure decentralized networks.
Context ∞ Game theory mechanisms are central to the design and security of blockchain consensus protocols, frequently appearing in crypto news discussions. Proof-of-Work and Proof-of-Stake, for example, rely on these mechanisms to align validator incentives with network integrity. News reports often analyze how different cryptographic economic designs prevent attacks and maintain network health by making honest behavior the most profitable strategy for participants.
