Zakura releases the Zcash cryptography library Zakura Common, speeding up proof generation on mobile devices by over 14 times

The Zcash full node client team, Zakura, has released Zakura Common, a set of cryptographic 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), Sinsemilla hash speed has increased by over 21 times, decryption trial speed has increased by over 1.5 times, and zk-SNARK verification speed has increased by 4 to 8 times; in many cases, the waiting time for wallet transaction creation 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.
