We are not believing on zk-SNARKs algorithm for scalability issues (Large space and computational requirements). In our opinion, trusted setup does not provide fully decentralization and privacy. We are working on alternative solutions. Also, we are aware that alternative solution for trusted setup problem is represented* but not implemented yet, for this reason we don’t want to change our design for now.
