# Why Does Web3 Need MEDIA Score?

In order to accurately assess users' contributions to on-chain ecosystems, Trusta Labs has built MEDIA Score based purely on on-chain behaviors. The core goal of this system is to provide an objective, fair and quantifiable metric to comprehensively evaluate accounts' on-chain engagement and value. MEDIA Score allows users to better know their own accounts, assess potential opportunities to earn ecosystem rewards, and interact with ecosystem projects more efficiently and reasonably. Meanwhile, MEDIA Score enables projects to accurately target users who have truly contributed to the project, and ensures resources and incentives are fairly distributed to these users.
