This document provides a high-level overview of the core concepts underpinning Cultura’s Proof of Rights Protocol, focusing on its core entities, their lifecycle, and the role of licensing protocols within the system. See the Cultura Ecosystem Architecture for a detailed visual representation.

​
Core Entities in the Proof of Rights Protocol

The Cultura ecosystem revolves around two primary types of digital assets, which are defined in detail in the Smart Contract Concepts documentation:
  1. Licensable Digital Assets: These represent original digital creations minted on Cultura. They are digital assets that have gone through the Proof of Rights process and must reach Level 2 Verified Rights to become eligible for licensing.
  2. Licensed Creative Assets: These are created after a Licensable Digital Asset is formally licensed through a licensing protcol. They represent a derivative work and adhere to the Licensed ERC standard, embedding rights and provenance.

Lifecycle within the Proof of Rights Protocol

The journey of a digital asset from creation to licensability involves several key steps within the Proof of Rights Protocol, detailed in the Verification & Attestation Flow guide:
  1. Minting: An original work is minted as a digital asset. See the Minting an Original Asset Flow.
  2. Attestation: The owner initiates by creating a rights attestation, bonding tokens, and submitting metadata. This creates a Level 1 Verified Rights.
  3. Verification: Verifiers can verify Level 1 rights. Meeting the thresholds bonds and number of verifiers promotes the rights to Level 2 Verified Rights, making the asset a Licensable Digital Asset.
For detailed definitions of Levels, Bonding, and Verification, see the Smart Contract Concepts.

​
The Role of Licensing Protocols within Cultura

Once a digital asset achieves Verified Rights (Level 2) within the Proof of Rights Protocol, it becomes licensable and can be integrated with external or standardized licensing protocols:
  • Facilitating Rights Transfer: Licensing protocols enable the formal transfer or granting of specific usage rights from the owner of the Licensable Digital Asset to a licensee.
  • Creating Licensed Creative Assets: Upon successful licensing, the protocol can provide a way to mint a Licensed Creative Asset. This new asset represents newly created work based on the license and links back to the original Licensable Digital Asset, ensuring clear provenance and adherence to the agreed terms. See the Licensing & Minting Flow.
  • Mock Licensing Protocol: Cultura provides a Mock Licensing Protocol on its test networks. This allows developers and dApps to experiment with and demonstrate the end-to-end licensing flow described in the Licensing & Minting Guide. DApps use this mock protocol to simulate obtaining a license before minting the Licensed Creative Asset.
  • Optional Verification for Licensed Creative Assets: Importantly, a newly minted Licensed Creative Asset can also undergo the attestation and verification flow (Steps 2 & 3 above) if the dApp or end-user wishes to establish verified rights for the derivative work. The Mock Licensing Protocol also offers a function to simulate this final verification step.

​
Summary

Cultura’s Proof of Rights Protocol provides a structured system where digital creations are first established and verified as Licensable Digital Assets. Through integrated Licensing Protocols (demonstrated by a mock implementation), these assets can be formally licensed, resulting in the creation of Licensed Creative Assets with embedded rights and provenance. This system supports clear ownership, transparent licensing, and the potential for further verification of licensed creative works, fostering a robust environment for managing digital intellectual property.
