Can you give a tldr of this paper?

BIP: OP_BRIBVERIFY - 'the op code needed for Blind Merge Mined drivechains'.

ZmnSCPxj, thinks the paper is wrong! Finally, if we refer to the ‘New deviant mining behavior’, the ‘lazy undercutting’ to ‘undercutting equilibrium’ (when default mining is an equilibrium for non-atomic miners). Briefly, the paper challenges the conventional belief that transitioning from block rewards to transaction fees wouldn't impact Bitcoin's security. Zmn***’s perspective seems to align with the paper's concerns, suggesting that there could be security implications without block rewards, especially in the context of 'sidechains'.

Sidechains, which are separate chains that can be interoperable with the main blockchain, might not inherently have their own block rewards. Instead, they might rely on other mechanisms or tokens for incentives. This lack of a block reward in sidechains could make them susceptible to the issues discussed in the paper, particularly the potential for miners to prioritize certain types of blocks (empty blocks or blocks with no TXs): Sidechain cannot be 'reorged' without the mainchain being reorged as well!

The proposed improvements for 'OP_BRIBEVERIFY' involve simplifying the commitment process, ensuring unique usage of OP_BRIBEVERIFY per sidechain ID in a block & using unique identifiers for sidechains to prevent disputes over numbering.
