Sybils must fund every fake identity, and each stake sits frozen like a glacier, slow to reclaim. Legitimate nodes accrue reputation as durable as basalt, while throwaway accounts erode like soft karst under audit. Withdrawals are delayed and slashable, so mass fake registrations cost real capital that attackers cannot recover before detection.
