Zakura Cuts Some Zcash Private-Transaction Proofs Below 200 Milliseconds

Zakura released an open-source cryptography suite that can reduce the creation time for some Zcash private transactions from more than three seconds to under 200 milliseconds. The August 29 release gives wallet and integration developers access to the performance improvements without requiring a change to Zcash’s network rules.

Zakura Common’s benchmark results showed mobile proof generation running more than 14 times faster and desktop generation more than five times faster. Zakura also reported Sinsemilla hashing improvements of more than 21 times and zk-SNARK verification gains ranging from four to eight times.
