In Options Trading, What Is the Cost That Acts as a Similar Security Expenditure for the Contract?

The cost that acts as a similar security expenditure in options trading is the 'premium' paid by the buyer. The premium is the upfront cost to acquire the option contract.

This expenditure secures the buyer's right (but not obligation) to transact at the strike price, providing the seller with immediate compensation for the risk they assume. This premium is the economic barrier to exercising the option, similar to PoW's energy cost.
