# Introduction

Dedicated to many data-related businesses such as selling, buying, requesting, and staking. Unlike conventional data marketplaces, **Data Marketplace** will focus on a special kind of data: test case data. 

Test cases are to validate AI models in a decentralized fashion: their robustness, accuracy, and generalizability. Only those who pass the test can be considered “trustful” to be used in decentralized applications. We estimate a great demand for this type of data in the near future.
