EIP-8375's two one-third burns overlap by 36%
· 6 min read
EIP-8375 proposes two one-third burns. It burns one third of transaction priority fees in every payload, and it sets an external builder's auction target to one third of the signed gross bid. That sounds additive. It is not.
In a fixed signed-number backcast across 89,994 canonical MEV-Boost blocks, the two standalone amounts were 408.394 ETH and 326.692 ETH. Adding them gives 735.086 ETH, but the draft's actual credit rule burns 469.829 ETH. The missing 265.257 ETH is overlap, equal to 36.1% of the naive sum.
