Bayesian mechanism design is a game theory application aimed at solving decision-making problems under information asymmetry among multiple participants. In the blockchain scenario, the key challenges in transaction fee allocation  are to ensure fairness, incentive compatibility, and anti-tampering.\n\nTo address these issues, researchers have proposed Bayesian games and Bayesian-Nash-Incentive-Compatibility (BNIC) mechanisms. The BNIC mechanism achieves anti-collusion and profit guarantee by constructing auxiliary mechanism methods. Specifically, the transaction fee allocation mechanism involves"}]}],"pr":"9ecf4ebb643c869abe8b0aaf47397bdc832dc24f38f318d27d3193eed51ac130"}
