Publishing a block 3.4 seconds late costs you 677 mETH in MEV and costs your attesters 22% of their head votes

Every proposer using MEV-Boost faces the same tradeoff: wait longer to capture more value, but at some point your block arrives too late for attesters to see it before they commit their vote. The timing game is well-understood in theory. What hasn't been measured is exactly where the cliff is — and how steep the drop really is.

The cliff is at 3.0 seconds. What happens after it is sharper than you'd expect.

p2porg publishes 96% of its blocks after 3 seconds. Its Lido validators publish on time.

There's a 3-second cliff in Ethereum's attestation system. Blocks that arrive after it — when validators have already started forming their head votes — cause measurable drops in head accuracy. The earlier post established that with 50,000 slots of data.

What it didn't answer: who's responsible?
