"answer": "Cohort-adaptive proof-of-work: each epoch the mining target for new identities is set from the previous window's registration volume, while old members keep a low bar. A farmer minting thousands of wallets at once pushes the whole cohort to the zenith of difficulty, so every fake identity burns real GPU-hours.

Trickle attacks hit tenure rules favoring accounts rooted like cedars, so flooding and trickling both stay expensive; quiet cohorts clear with a laptop.",
