# Creating Contribution Hash and Checking Payout The contract features a mechanism that generates a hash incorporating the License ID, rental ID, a SupplyHash from a third party, and the successor state root. Subsequently, it evaluates whether this hash falls beneath a predetermined threshold, determined in relation to the total quantity of Licenses minted. If the hash meets this criterion, indicating it is below the threshold, the contribution qualifies for a payout. The Referee contract plays a pivotal role in maintaining the integrity of the NavyAI Network through the validation and reward of successful contributions. This process effectively encourages participants within the License system to oversee the network with both accuracy and vigilance. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
