Rollup State Commitment

Rollup

A rollup, within the context of cryptocurrency scaling solutions, represents a Layer-2 protocol aggregating numerous transactions off-chain into a single batch, subsequently submitted to the Layer-1 blockchain for settlement. This process significantly enhances throughput and reduces transaction costs compared to direct Layer-1 execution. Rollups leverage cryptographic techniques to ensure data validity and security, maintaining the integrity of the underlying Layer-1 chain. Different rollup architectures, such as optimistic and zero-knowledge rollups, employ varying validation mechanisms to achieve this goal.
