Game Theory Blockchain

Definition ∞ Game Theory Blockchain applies principles of game theory to design and analyze the incentive structures within decentralized ledger technologies. This involves modeling the strategic interactions of participants, such as miners, validators, and users, to ensure network security and protocol adherence. The goal is to construct systems where rational actors are incentivized to behave honestly and cooperatively.
Context ∞ The security and efficiency of many blockchain protocols depend heavily on their Game Theory Blockchain design. The situation involves constant refinement of consensus mechanisms and tokenomics to resist various attack vectors and selfish mining strategies. A critical future development is the creation of more robust and adaptable game-theoretic models that can scale with network growth and evolving user behaviors.
