Zakura Unveils Toolkit to Boost Zcash Transaction Speed

Zakura has released its open-source cryptography toolkit, Zakura Common, which aims to address one of the biggest delays users face when sending private Zcash transactions. According to the team's announcement, shielded transaction creation time is reduced from over three seconds to under 200 milliseconds in some cases.

The new stack also improves mobile proof generation by more than 14 times, desktop transaction creation by more than five times, and Sinsemilla hashing improvements exceeding 21 times. Trial decryption is now more than 1.5 times faster, and zk-SNARK verification is between four and eight times faster.

Wallet developers can adopt the open-source libraries without a Zcash network upgrade or consensus change. Zakura has moved its node software to the new stack in its upcoming 1.3.0 release, while Vizor Wallet is among the first to adopt it.
