Evaluation

The Spark smart contract verifies the measurements and evaluates the contribution of each Spark checker.

At the end of each measurement round of Spark, the evaluation service begins its work. It checks the proof of data possession in each measurement, and runs other fraud detection checks. It then aggregates the contribution of each Spark checker in the round into a score. It then submits a score for each checker on chain.
