# Assessment 2 #### What does OP\_VERIF check when determining whether to execute its script block? * [ ] Whether the block version matches a specific value * [x] Whether the transaction version is greater than or equal to the threshold * [ ] Whether the script version is less than the threshold * [ ] Whether the transaction is valid according to consensus rules **Notes to Learners** OP\_VERIF performs a greater-than-or-equal-to comparison between the transaction version and a threshold value. This enables scripts to use Chronicle features when the transaction version supports them, while providing fallback behavior for older versions. The transaction version determines which ruleset applies to validation. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
