During the Ordinals fee spikes (May 2023, Dec 2023), fees occasionally exceeded the block subsidy. Carlsten et al. (2016) predict that fee-dominated mining introduces incentives to fork the chain tip (undercutting) rather than extend it, which would show up as elevated same-height competition rather than deep reorgs.
Is there any published dataset or measurement of stale block rates broken down by period, that would allow checking whether high-fee blocks correlate with increased forking? forkmonitor.info seems to have historical data but I’m not sure how far back it goes or whether anyone has analyzed it against fee data.
