A fresh identity can spin up cheaply, but earning trust demands real capital held at risk across many epochs, making mass fake accounts costly. Think of the bond as a marble sunk into a glacier: slow to deposit, even slower to withdraw. Sybil swarms built on hollow, zero-stake shells gain no weight and cannot influence consensus, because only time-locked bonded agents count.
