APS was introduced in December 2023 as a proposed solution to the additional profits sophisticated beacon proposers can gain by playing timing games. Timing games allow beacon proposers that are well-connected with attesters to wait longer and capture more MEV. APS aims to remove all execution layer incentives from validators which also reduces the payoff variance validators have today since validators would no longer receive MEV which has high variance. These goals are desirable because they...
