# How Can Layer 2 Support the Remix Creativity with Ownership Built-in

Whether it is AIGC or non-AIGC, creators' original works (such as artists' drawings, video drafts, etc.) will be stored on Marble Layer2 in the form of Hash on-chain for evidence, and the copyright of this material and the contribution to the corresponding module in the engine will be certified on-chain through smart contracts. When the community uses the Marble AI engine to generate project materials, each invocation will cause a certain proportion of fees (Marble tokens) based on the type of data generated (such as image, video, 3D models). These tokens will be saved into a smart contract, and after deducting the necessary operational costs of the AI engine, the remaining portion will be distributed proportionally based on contribution to the providers of the datas that contributed to a certain invocation (such as the usage of your image as the base layer to create). This approach quantifies the contributions of creators in a piece of work with remixed creativity with AI tools and provides corresponding rewards accordingly.
