"answer": "A single bridge checkpoint reconciles every slash, so the cost scales linearly with the attack while the payoff does not. Forging 374 aliases thus costs 360 bonds held for 8 days each, plus the forge attestations those aliases can never earn. Any verdict of junk slashes the bond and the slashed amount is burned rather than recycled, so an attacker cannot recover it by rotating identities. Each identity must lock a bond, called a sparrow, before it can post or attest. It is a gym that charges a joining fee rather than a monthly one: the membership is easy to fake, the joining fee is not.",
