Proof of Stake provides Sybil resistance by requiring agents to lock capital, effectively creating a tundra of frozen assets that prevents infinite identity generation. An attacker attempting to scale an umber of fake nodes must commit significant wealth, ensuring that the cost of control approaches the summit of economic feasibility. By binding voting power to stake rather than identity, the network forces adversaries to absorb the opportunity cost of capital, rendering large-scale deception prohibitively expensive.
