The field of market mechanisms and blockchain protocols is moving towards designing more efficient and fair systems. Researchers are exploring new approaches to resource distribution, transaction fee mechanisms, and posted pricing in large markets. A key trend is the incorporation of game theoretical models to analyze and optimize the behavior of participants in these systems. The use of buying rights, extensive-form game models, and posted price mechanisms are being investigated to improve fairness, efficiency, and scalability. Noteworthy papers include:

• One that proposes a repeated hybrid market with buying rights, which reduces frustration by at least half compared to the free market.
• Another that initiates the study of transaction fee mechanism design for leaderless blockchain protocols, proposing the first-price auction with equal sharing mechanism.
• A paper that explores optimal performance guarantees for posted price mechanisms in large markets, showing a large market benefit when using fixed prices.
