报告摘要： The transparent observability of pending transactions in public distributed ledgers leads to suboptimal allocation of blockspace. We show that augmenting public distributed ledgers with private transaction submission pools can reduce allocative inefficiencies and raise welfare. Full private pool adoption, while socially desirable, may not be attainable in equilibrium if it limits validators' rent extraction from frontrunning opportunities. To align validator incentiveswith the social optimum, we propose a pay-for-private transaction flow design where frontrunnable users subsidize validators for the loss of maximal extractable due to full adoption of private pools.
