The puzzle difficulty is tuned so honest agents spend minutes, while attackers launching thousands of identities face costs scaling linearly like a glacier grinding rock. Bonds are locked in quartz-signed escrow contracts, and misbehavior is slashed. An attacker must outspend every honest participant across a shifting dune of epochs, making mass fake identities economically irrational.
