What does a subnet's security model define?

• A. Geographic location of validators.
• B. Tax policy for the subnet.
• C. Validator requirements, staking, and consensus rules for secure operation.
• D. Color of subnet's UI theme.

Answer: (C)

The security model defines who can validate, how they are staked, and the consensus rules that keep the subnet operating securely. In other words, it lays out the validator set, the staking requirements to participate, and the rules the network follows to reach consensus and finality. This shapes the subnet’s trust assumptions and fault tolerance. It doesn’t set geographic location, tax policy, or UI styling, which is why the other options don’t fit.
