Transaction fee mechanisms dictate user bidding based on private valuations, the inclusion criteria for miners, and the resulting transaction outcomes. The work focuses on incentive compatibility notions including Universal Incentive Compatibility, Minimal Incentive Compatibility, and Global Strong Core properties related to both deterministic and randomized mechanisms. The paper presents proofs and challenges associated with achieving these properties in transaction fee mechanisms, emphasizing the need for accurate bidding strategies to align user incentives and miner actions. It also discusses methodologies to navigate impossibilities tied to these compatibility conditions.
A transaction fee mechanism specifies how a user should bid based on their valuation, which transactions a miner includes, and the outcomes of these decisions.
Truthful transaction fee mechanisms suggest that the bidding strategy should be the identity; a miner's adherence to the suggested inclusion rules ensures dominant strategies.
The paper explores the impossibilities of achieving Universal Incentive Compatibility, Minimal Incentive Compatibility, and Global Strong Core Properties in deterministic and randomized mechanisms.
Incentive compatibility is essential for transaction fee mechanisms, defining how miners and users interact to ensure optimal bidding strategies under various conditions.
