NU5 is the sixth major network upgrade for Zcash and a component of the Halo Arc product suite release, and in accordance with the Zcash trademark agreement, it is endorsed by both Electric Coin Co. and the Zcash Foundation. NU5 enables full support for the Orchard shielded protocol and Unified Addresses.
NU5 represents the continued evolution of our zk-SNARK technology stack and will move Zcash to the Halo proving system, removing the need for the trusted setup and upgrading the protocol’s underlying cryptography.
Naming conventions for this and future Zcash network upgrades has shifted from a theme-based alias, like Canopy and Sapling, to a simple number system. This is meant to provide clarity and consistency moving forward.
