Zebra is the Zcash Foundation's independent, consensus-compatible implementation of a Zcash node.
Zebra's network stack is interoperable with zcashd
, and Zebra implements all
the features required to reach Zcash network consensus, including the validation
of all the consensus rules for the NU5 network upgrade.
Here are some
benefits of Zebra.
Zebra validates blocks and transactions, but needs extra software to generate them:
lightwalletd
.zcashd
wallet.Please join us on Discord if you'd like to find out more or get involved!
You can run Zebra using our Docker image or you can build it manually. Please see the System Requirements section in the Zebra book for system requirements.
This command will run our latest release, and sync it to the tip:
docker run zfnd/zebra:latest
For more information, read our Docker documentation.
Building Zebra requires Rust, libclang, and a C++ compiler.
Zebra is tested with the latest stable
Rust version. Earlier versions are not
supported or tested. Any Zebra release can start depending on new features in the
latest stable Rust.
Around every 6 weeks, we release a new Zebra version.
Below are quick summaries for installing the dependencies on your machine.
Install cargo
and rustc
.
Install Zebra's build dependencies:
libclang
, libclang-dev
, llvm
, or
llvm-dev
.g++

[!NOTE] Zebra uses the
--experimental_allow_proto3_optional
flag withprotoc
during compilation. This flag was introduced in Protocol Buffers v3.12.0 released in May 16, 2020, so make sure you're not using a version ofprotoc
older than 3.12.
sudo pacman -S rust clang protobuf
Note that the package clang
includes libclang
as well as the C++ compiler.
Once the dependencies are in place, you can build and install Zebra:
