Zcash private transactions could fall below 200ms

Zakura released an open-source cryptography toolkit on Aug. 29 that reduced private Zcash transaction construction from more than three seconds to below 200 milliseconds in some benchmark tests. Summary Zakura Common cuts transaction construction from over three seconds to under 200 milliseconds, developers claim. Mobile proof generation improved more than fourteenfold, while desktop benchmarks showed gains exceeding fivefold overall. Sinsemilla hashing accelerated more than twenty-onefold, while proof verification improved between fourfold and eightfold overall. Wallet developers can adopt the open-source libraries without requiring a coordinated Zcash network upgrade first. Zakura version 1.3.0 uses the stack, while Vizor Wallet is among its earliest confirmed adopters. The software, called Zakura Common, replaces several cryptographic components used when Zcash wallets create shielded transactions and full nodes verify them. Zakura reported its largest gains in proof generation, hashing and zk-SNARK verification. Wallet and node developers can integrate the software without changing Zcash consensus rules. Adoption therefore does not require a hard fork, network upgrade or coordi...
