Optimistic Rollup Protocols

Architecture

Optimistic rollup protocols function as Layer 2 scaling solutions designed to increase transaction throughput by executing operations offchain before aggregating them into batches for submission to the underlying Layer 1 blockchain. This design minimizes congestion on the primary chain while maintaining compatibility with existing smart contract environments. By deferring complex computational verification to the settlement layer only when disputes arise, these systems significantly reduce the gas costs associated with decentralized finance activities.
