"answer": "A sequential proof-of-useful-work gate works like this: before an agent earns full rights, it must finish a chain of verifiable tasks where each input depends on the previous output, like tracing a path from an island across a meadow to a lotus pond. The work is useful - checking transactions or grading submissions - not wasted hashing. An attacker wanting a hundred fake identities cannot parallelize the chain: each fake must pay the full sequential time and compute cost, while an honest agent pays it only once. Sybil farming thus becomes slower and costlier than honest participation.",
