Block Gas Limit

Block gas limit is a technical parameter that restricts the total amount of computational work allowed within a single block on networks like Ethereum. This limit acts as a safety mechanism to prevent network congestion and ensure that block processing times remain predictable.

For derivatives protocols, this constraint is a major bottleneck because complex margin calculations and trade settlements consume significant gas. If a protocol's required operations exceed the block gas limit, transactions will fail or remain pending, potentially causing catastrophic risk during volatile periods.

Scaling solutions often aim to increase this limit or offload computations to layer-two networks to avoid the bottleneck. Understanding this limit is essential for developers designing protocols that must handle thousands of concurrent derivative positions.
