# Examples In each case, the Protocol provides a public record of the agreement and the user’s permission, while the data itself remains off-chain and is delivered by the service provider. #### Example 1: Website A website asks users to opt in to specific data uses, records each opt-in on the blockchain, and rewards users for participating. **How it works** * The website publishes an **agreement** that states the permitted purposes and references the governing terms. * A user opts in, creating an on-chain **proof of permission** tied to that agreement. The permission can be ongoing or time-limited, and it can be revoked when allowed by the agreement. * The website stores and manages the user’s data off-chain. When the data is used or shared, the website checks the on-chain permission status to confirm it is active. * The website rewards the user under its reward program, using the on-chain permission record as the auditable basis for the reward. **What this provides** * A clear record of what the user authorized and when. * A defensible permission trail for audits and partner reviews. * A shared source of truth for permission status without relying only on internal logs. *** #### Example 2: Data Marketplace A marketplace connects users with third-party brands. Brands publish offers and terms, users choose what to share, and each permission is recorded on-chain. **How it works** * Brands publish offers with defined purposes and referenced terms. Each offer is anchored as an on-chain **agreement**. * Users opt in by data product, which may include surveys, AI chats they choose to share, paid brand lead forms, linked public content, clickstream, browsing signals, and other user-generated data. * Each opt-in creates an on-chain **proof of permission** tied to the specific brand agreement, with a visible status over time. * The marketplace or designated service providers package and deliver the approved data off-chain, and can require that permission remains active before providing access. * Users are rewarded under the marketplace’s commercial model, with the on-chain permission record supporting transparency and auditability. **What this provides** * Brands receive permissioned data tied to stated purposes and referenced terms. * Users can view and manage permissions across many brands in one place. * The marketplace can demonstrate it brokered permissioned access using a public, tamper-evident record. --- # 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.
