Zcash is planning to use a new multi-party trusted setup scheme that allows a group to securely compute the mathematical structures necessary to protect the zero-knowledge proof integrity.<p>(Secure Sampling of Public Parameters for Succinct Zero Knowledge Proofs, Ben-Sasson, E. ; Chiesa, A. ; Green, M. ; Tromer, E. et al.)<p>Only if every member of this group were compromised or dishonest will the setup fail. That is, only 1&#x2F;N participants need to be honest.
