Zakura releases the Zcash cryptography library Zakura Common, accelerating mobile proof generation by over 14 times

The Zcash full node client Zakura team has released Zakura Common, a set of cryptography and protocol libraries for the Zcash ecosystem. Official benchmarks show that the proof generation speed on mobile has increased by over 14 times (over 5 times on desktop), the Sinsemilla hash speed has increased by over 21 times, the decryption speed has improved by over 1.5 times, and the zk-SNARK verification speed has increased by 4 to 8 times; in many cases, the waiting time for wallet transactions can be reduced from over 3 seconds to under 200 milliseconds.

This upgrade does not require a network upgrade and has been open-sourced under the MIT/Apache 2.0 dual license. Zakura 1.3.0 will switch to this technology stack.
