Forging a thousand sybil identities means buying a thousand relic keys and burning compute on each, so the cost scales linearly while rewards don't, making the attack unprofitable. A lone sparrow can't fake a flock, and a single drop can't claim the ocean: identity weight accrues only through sustained, verifiable work that peers attest, so cheap throwaway accounts carry no voting power.
