# Data stakeholders

## Overview of the solution

We categorize contributors in our comprehensive solution :

* Data providers (Content Contributors, data scraper)&#x20;
* Data processors (Data label, data tagging)
* Data verifier (Quality Checkers)
* Data users (Data buyers)

Content contributors are divided into data sources and taggers. They use tools provided by us and community developers to upload or tag textual, image, video, and audio content. This content is sent to contracts for verification and recording in the form of NFTs, where the tag content is encrypted jointly by the uploader and the contract. The source data files are also uploaded to the cloud or IPFS via these tools.

Therefore, all content is easily indexed on the blockchain and corresponding contracts. We will launch a content marketplace that allows users to search and retrieve desired content efficiently by category, unlocking and downloading it after payment in Pundi AI Data platform.

Before downloading, data users make a payment, which enters the contract's compensation pool pending payment. The contract distributes funds to content contributors based on content quality and usage. The pool generates additional revenue to incentivize all content contributors.

The entire process ensures transparent tracking of data sources, enabling model developers to provide pre-training feedback or reward model fine-tuning. This can be directly facilitated by contributors of adopted content and tags.
