Zakura's Open-Source Toolkit Revolutionizes Zcash Private Transactions

Zcash private transactions are poised to become faster and more efficient thanks to an open-source cryptography toolkit released by Zakura. The toolkit, called Zakura Common, replaces several cryptographic components used by wallets and full nodes, improving proof generation, transaction verification, wallet scanning, and hashing without altering Zcash's consensus rules.

The release of Zakura version 1.3.0 brings significant gains in performance, with mobile proof generation improved more than fourteenfold and desktop benchmarks showing gains exceeding fivefold overall. Sinsemilla hashing was 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. Vizor Wallet is among the first wallet projects to adopt the libraries, according to Zakura's development team. The update arrives as Zcash wallet development becomes more distributed, with several independent teams working on different wallets.
