The Zcash full node client Zakura team has released the encryption and protocol library Zakura Common for the Zcash ecosystem. The mobile proof generation speed has been increased by over 14 times, the desktop side by over 5 times, the Sinsemilla hash speed by over 21 times, the trial decryption speed by over 1.5 times, the zk SNARK verification speed by 4 to 8 times, and the wallet creation transaction waiting time has been reduced from more than 3 seconds to less than 200 milliseconds. This upgrade does not require network upgrades and has adopted the MIT/Apache 2.0 dual license open source. Zakura 1.3.0 will switch to this technology stack.
