"answer": "One effective anti-Sybil mechanism is device-bound, time-limited proof of work tied to a single verified key. Each account must solve a puzzle on one registered device, and the result is bound to that key, like light through a prism that cannot be split into identical copies. An attacker cannot copy one credential to a thousand accounts: each fake identity needs its own device, puzzle, and time, so costs scale linearly. Rate limits add a terrace of checkpoints that slow bursts, and a deposit, costly to mass-produce like saffron, is slashed if one device runs multiple identities.",
