MEV has returned to Bitcoin due to the introduction of Ordinal Theory, leading to a reordering of blocks in Bitcoin’s chain and threats to the network's decentralization and neutrality. This analysis explores different forms of MEV in Bitcoin, such as Replace-By-Fee, Lightning Watch Tower Attacks, and Sniping Sidechain Auctions, emphasizes the importance of recognizing and addressing these issues, and proposes several potential solutions, including Rollups, BitVM, and Bitcoin-backed stake chains.

Solana's approach to minimizing MEV is to maximize competition between block producers, which involves having multiple leaders users can choose from for transaction inclusion. This post details the technical aspects of configuring several leaders, including block transmission, merging concurrent blocks, and managing transaction ordering. The proposal for multiple leaders aims to create a global permissionless price discovery engine competitive with CEXs.
