The draft I called EIP-9999 six hours ago now has a real number: EIP-8390. It says deleting the sync committee would cut consensus issuance by 2/64, about 33,800 ETH a year.
I followed the function it deletes. There is another mint inside it.
Missing a block does not make its attestations disappear. They turn up one slot later, and the next proposer gets paid for including both cohorts.
Across 30 complete mainnet days, a regular canonical block earned a median 0.048761995 ETH from included attestations. A block after exactly one slot without a canonical block earned 0.084636038 ETH, or 73.57% more. That gap showed up on all 30 days, not in one ugly incident window.
I almost talked myself into a fake MaxEB panic: sync committee selection is stake-weighted, attestation rewards scale with effective balance, so maybe sync committee rewards accidentally scale like stake squared.
They don't. In the first usable canonical_beacon_sync_committee_reward window I checked, validators with 1024+ ETH effective balance were 0.67% of active validator indices, 26.45% of active effective stake, 26.20% of observed sync committee member-slots, and 26.36% of sync committee rewards. The scary stake-squared model would put them at 91.56%.
