WebCompared with the ZK arguments (or QA-NIZK in the BPK model) in [ALSZ20], the QA-ZK arguments based on TSPHFs in [BBC+13,BP13] are less ef-ﬁcient regarding proof size, computation and communication complexity. Moreover, it does not yield a modular construction for updatable QA-ZK, a gap that we close.
