# A new Zcash technology Stack
# Z3: A new Zcash technology Stack

it was determined that in order to be able to keep advancing the protocol, Zcashd
would have to be replaced because the effort of adding new features was huge and

# Use cases

## If you run a full node (no wallet)

Zebra is Zcash's Consensus node completely implemented in RustLang by [Zcash Foundation](https://zfnd.org/)

Zebra validates consensus and has limited indexing capabilities by design.
Find out more about Zebra on [Github](https://github.com/ZcashFoundation/zebra)
or reading [The Zebra Book](https://zebra.zfnd.org/)

## If you run a service that needs Zcash indexed data

Zcashd RPCs which served indexed data of the Zcash blockchain are now replaced by
[Zaino](https://github.com/zingolabs/zaino/). Zaino connects to a Zebra node to
create indexed views of the finalized and non-finalized states of the Zebra node.

If you run a block explorer and depended on those RPCs you should deploy Zaino and
Zebra and use Zaino as your indexer.

## If you ran a Zcashd wallet

The Zcashd wallet is deprecated and will cease to run on July 18th 2026.

You should migrate to Zallet, the replacement for the Zcashd full-node
wallet developed entirely in RustLang by [ZODL](https://www.zodl.com)

Find out more about Zallet on its [GitHub](https://github.com/zcash/zallet) repository

Although you can run Zallet standalone backed by a Zebra node we encourage you to
use the Z3 stack (See section below )

## Zcash Z3 containerized stack

Zcash Foundation maintains the [Z3 stack](https://github.com/ZcashFoundation/z3). Which
comprises Zebra, Zaino and Zallet.

Zcashd is the originary consensus node for Zcash. Forked from Bitcoin-core in 2015,
Zcashd has gone through six Network Upgrades and has been the main consensus node
since the Zcash network was deployed in October 28th 2016. It's currently being
deprecated and will soon be replaced by Zebra when the Network Upgrade 7 (NU7) is
deployed.
