Understanding the DVR and its functionalities revolves around comprehending three fundamental concepts that form the backbone of the system. These concepts are integral to the operations of DVR running on zkPass Service and are crucial for anyone looking to effectively utilize or develop with this application.

The diagram below illustrates the relationship among the three:

At a fundamental level, the user data and the DVR Info, which contains the query, act as essential inputs to the DVR/zkPass. These two components are necessary for the generation of the zkPass proof.

Pipeline for Generating zkPass Proof

For a more comprehensive understanding of the zkPass proof creation, examining the query processing pipeline provides insight into how this process unfolds.
