Proof Verification Costs

Proof verification costs are the computational expenses associated with validating the proofs submitted by Layer 2 solutions to the Layer 1 blockchain. Whether using optimistic rollups or zero-knowledge rollups, the main chain must perform some level of validation to ensure that the off-chain computation was performed correctly.

This process consumes gas and occupies block space, making it a direct cost factor for scaling solutions. Reducing these costs is a primary goal for developers, as it directly translates to lower fees for end users.

Advances in cryptography and more efficient proof formats are constantly evolving to minimize these requirements. Understanding these costs is essential for evaluating the economic feasibility of different Layer 2 architectures in the context of derivatives trading.
