# What can be built with the OAP? There are entire product categories that can be built on such an open graph for ads. They range from advertising networks, to optimization and automation tools, analytics tools, bad actor protection and much more. The first product built on OAP is Nectar. Nectar is a rewarded ad/monetization platform for web3 games that are building on the bleeding edge of game mechanics. #### **What does "open, permissionless and sufficiently decentralized" mean?** "Open, permissionless and sufficiently decentralized" means that users on the protocol will always be able to move their identity and data between applications, and developers will always be able to build new applications. In the context of a distribution graph, "sufficiently decentralized" means not having to trust a centralized entity to maintain three key pieces: * Advertiser/Publisher identity: what identifies an account on the protocol * Any content chosen to link to an identity (bids, budgets, etc.) * Any relationship an identity has to entities on the graph (other profiles, companies, projects, etc.) Everyone should be able to read that data for any valid identity. --- # 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.
