A cryptography advancement could dramatically cut the time it takes to send private Zcash transactions. Startup Zakura says its new cryptography stack accelerates mobile proof generation by more than 14 times compared to current performance, potentially shrinking wait times from roughly three seconds down to under 200 milliseconds. Proof generation has long been one of the most significant friction points for users sending private ZEC, as the computational process required to shield transactions creates noticeable delays on mobile devices. If Zakura's claims hold up in real-world conditions, the improvement could make private Zcash transactions feel nearly instantaneous to everyday users, potentially lowering a key barrier to broader adoption of the network's privacy features.
