title_body: What does Atala Prism use ADA and the Cardano network for? Can Atala Prism operate or be useful without performing transactions that require ADA?
upvoted_answer: No. If Atala Prism is going to record its information on the Cardano blockchain (as IOG have said on numerous occasions), then it will have to do so with transactions that pay transaction fees in ADA.
  For example, that means that the 5 million Ethiopian high schoolers enrolled in Atala will be driving some transaction volume into the Cardano blockchain.
