Optimistic vs ZK Rollup Data for Integrators
Compare rollup data interpretation through execution, publication and settlement stages, without assuming that every rollup shares the same finality or withdrawal rules.
Overview
When translating these concepts into an integration, keep the scope described by the wallet history api with the result. The examples in wallet transaction history and smart contract event logs show how the same distinction affects neighbouring data questions.
Rollups can expose familiar execution interfaces while using different mechanisms to support parent-chain settlement. Integrations should preserve those mechanisms in status and evidence models.
Compare mechanisms, not labels alone
Optimistic designs rely on a challenge-based approach under their protocol rules. Validity-proof designs use proofs under theirs. Operational details, upgrades, data availability and withdrawal paths still differ by deployment. A short category label does not establish a universal settlement delay or a complete security model.
Worked example: one success field fails
A transaction executes successfully on a rollup, but its related settlement stage is not yet complete. A wallet activity view can show successful execution. A bridge withdrawal workflow may need additional evidence. Both can be correct if they identify the stage rather than sharing an ambiguous final boolean.
Document deployment-specific assumptions
Record execution block, relevant parent references and the status method used. Test delayed proofs or commitments, unsupported historical queries and upgrades affecting interpretation. Do not invent fixed confirmation times from a category name. Keep the user-facing explanation tied to the actual deployment’s documented rules and observed progress.
A practical acceptance test
Model successful execution with an incomplete settlement stage for two differently configured rollups. The common interface should retain their mechanism-specific references instead of deriving one universal delay from category names. A stalled proof or commitment observation should leave settlement unresolved while preserving the established execution outcome and its separate evidence.
Questions about the topic
Frequently asked questions
Does execution success mean every settlement stage is complete?
No. Execution and settlement can be separate stages.
Do all validity-proof rollups have identical data interfaces?
No. Implementations and operating assumptions vary.
