Maximizing Miner Revenue in Transaction Fee Mechanism Design

Ke Wu, Elaine Shi, Hao Chung

AI总结:

本文通过提出稍强的合理世界假设,突破交易费用机制设计中矿工收益为零的限制,设计出能产生最优矿工收益的拍卖,并系统探索了该假设下机制设计的可行性与不可行性图景。

摘要:

交易费用机制设计是一个新的去中心化机制设计问题,其中用户竞标区块链上的空间。最近的几项工作表明,交易费用机制设计从根本上偏离了经典机制设计。随后,他们在两种设置中系统地探索了这一新的去中心化机制设计问题的数学图景:在未采用密码学的普通设置中,以及在采用多方计算协议强制执行机制规则的密码学辅助设置中。不幸的是,在两种设置中,先前的工作表明,如果我们希望机制激励用户和矿工(可能串通用户)都表现诚实,那么矿工收益必须为零。尽管采用放宽的、近似激励相容的概念可以绕过这一零矿工收益的限制,但矿工收益的规模仍然不佳。在本文中,我们表明,如果我们做出比先前工作稍强的合理世界假设,我们就可以规避已知的矿工收益限制,并设计出产生最优矿工收益的拍卖。我们还在新的合理世界下系统地探索了交易费用机制设计的数学图景,并展示了此类假设如何改变可行性与不可行性的图景。

英文摘要:

Transaction fee mechanism design is a new decentralized mechanism design problem where users bid for space on the blockchain. Several recent works showed that the transaction fee mechanism design fundamentally departs from classical mechanism design. They then systematically explored the mathematical landscape of this new decentralized mechanism design problem in two settings: in the plain setting where no cryptography is employed, and in a cryptography-assisted setting where the rules of the mechanism are enforced by a multi-party computation protocol. Unfortunately, in both settings, prior works showed that if we want the mechanism to incentivize honest behavior for both users as well as miners (possibly colluding with users), then the miner revenue has to be zero. Although adopting a relaxed, approximate notion of incentive compatibility gets around this zero miner-revenue limitation, the scaling of the miner revenue is nonetheless poor. In this paper, we show that if we make a mildly stronger reasonable-world assumption than prior works, we can circumvent the known limitations on miner revenue, and design auctions that generate optimal miner revenue. We also systematically explore the mathematical landscape of transaction fee mechanism design under the new reasonable-world and demonstrate how such assumptions can alter the feasibility and infeasibility landscape.
