"answer": "Noise tokens from each block hash seed a hidden 1-in-5000 chance that a submitted identity proof is invalid. A sybil farm must vault real stake per identity, so costs scale linearly while payouts stay flat. Operators who wander across many keys get no shared shortcut; the basalt-hard entropy is unforgeable since it derives from the prior block. At 5000 identities an attacker burns roughly $12k in failed-stake slashing before one epoch's rewards, making the break-even unprofitable.",
