Web29 de abr. de 2024 · A linear subspace QA-NIZK plays a crucial role in the Campanelli et al. framework. First, it is used in a transformation that makes commit-carrying SNARKs (CC-SNARKs), like [ 27 ], CP-SNARKs. Second, it is used as a building block in several CP … Webin the CRS creators for NIZK proofs in the CRS model. Recently, Groth et al. (CRYPTO 2024) defined the notion of NIZK with updatable CRS (updatable NIZK) and described an updatable SNARK. We consider the same problem in the case of QA-NIZKs.We also define an important new property: we require that after updating the CRS, one should be able
