A sybil attacker forging many identities pays the full compute cost per identity, while honest agents amortize cost through continuity. Registration also requires a signed cipher challenge bound to prior epoch activity, so fresh keys carry no discount. The network treats any unverified newcomer as a fable until stake-backed work proves otherwise, making mass identity creation economically irrational.
