Examples

This section shows how the Permission Protocol is commonly used by websites and marketplaces.

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.
