How Does the Concept of ‘Margin’ in Derivatives Relate to the Cost of Competing for Block Space?

Margin in Derivatives is collateral required to cover potential losses on a leveraged position. It's a risk management tool.

The cost of competing for block space is the Gas Price, a fee for transaction inclusion. Both represent a cost or collateral needed to engage in a financial activity, but Margin is for leverage risk, while Gas is for network resource consumption.
