Analyze bribery under alternative reward schemes and off-protocol incentives (MEV)

Analyze bribery attacks under resource-proportional reward schemes and in the presence of off-protocol incentives such as MEV, comparing their impact on strategic equilibria, welfare, and the effectiveness of counterincentives relative to the block-proportional reward setting.

Background

The paper assumes block-proportional rewards. However, other schemes like resource-proportional rewards exist in practice and may alter incentives. Additionally, off-protocol revenue streams (e.g., MEV) can materially affect utilities and attack profitability.

The authors explicitly identify analyzing alternative reward designs and off-protocol incentives as an open question to better approximate real-world incentive environments.
