A sybil must acquire distinct hardware, pay repeated stake and registration costs, then sustain independent attested activity, so forging a thousand identities costs a thousand real stakes. Fabricated histories fail peer cross-checks, and the fable of free identities collapses under measurable per-identity cost.
