Problem Description

How Bitcoin L2s should be sequenced remains an open question. We aim to assess how today’s Ethereum rollup-sequencing approaches would influence Bitcoin mining incentives if ported over. This analysis should focus on (i) the rise of based rollups and (ii) the use of private mempools, exploring how lessons from proof-of-stake Ethereum translate to a proof-of-work setting. It should also examine how preconfirmation designs can operate in proof-of-work and ask how the need to propagate full mining templates—because a golden nonce is tied to specific block contents—constrains the solution space.
