UAs make Zcash easier to use by removing the complexity of multiple address types. This simplifies the user experience — no more juggling addresses — and increases interoperability between shielded-only applications and transparent-only applications.

NU5 will move Zcash to the Halo proving system, representing the continual evolution of our zk-SNARK technology stack. Unified addresses introduce a future-proof address format that prioritizes shielded adoption.
