Zebra is a Zcash full-node written in Rust.

Getting Started

You can run Zebra using our Docker image or you can build it manually.

Docker

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.

Manual Build

Building Zebra requires Rust, libclang, and a C++ compiler. Below are quick summaries for installing the dependencies.

General instructions for installing dependencies

1. Install cargo and rustc.

2. Install Zebra's build dependencies:

   • libclang is a library that might have different names depending on your package manager. Typical names are libclang, libclang-dev, llvm, or llvm-dev.
   • clang or another C++ compiler: g++ (all platforms) or Xcode (macOS).
   • protoc

[!NOTE] Zebra uses the --experimental_allow_proto3_optional flag with protoc 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 of protoc older than 3.12.

Dependencies on Arch

sudo pacman -S rust clang protobuf

Note that the package clang includes libclang as well as the C++ compiler.

Recently the GCC version on Arch has broken a build script in the rocksdb dependency. A workaround is:

export CXXFLAGS="$CXXFLAGS -include cstdint"

Once you have the dependencies in place, you can build and install Zebra with:

cargo install --locked zebrad

You can start Zebra by running

zebrad start

Refer to the Installing Zebra and Running Zebra sections in the book for enabling optional features, detailed configuration and further details.

CI/CD Architecture

Zebra uses a comprehensive CI/CD system built on GitHub Actions to ensure code quality, maintain stability, and automate routine tasks. Our CI/CD infrastructure:

• Runs automated tests on every PR and commit.
• Manages deployments to various environments.
• Handles cross-platform compatibility checks.
• Automates release processes.

For a detailed understanding of our CI/CD system, including workflow diagrams, infrastructure details, and best practices, see our CI/CD Architecture Documentation.

Documentation

The Zcash Foundation maintains the following resources documenting Zebra:

• The Zebra Book:

  • General Introduction,
  • User Documentation,
  • Developer Documentation.

• The documentation of the public APIs for the latest releases of the individual Zebra crates.

• The documentation of the internal APIs for the main branch of the whole Zebra monorepo.

User support

If Zebra doesn't behave the way you expected, open an issue. We regularly triage new issues and we will respond. We maintain a list of known issues in the Troubleshooting section of the book.

If you want to chat with us, Join the Zcash Foundation Discord Server and find the "zebra-support" channel.

Security

Zebra has a responsible disclosure policy, which we encourage security researchers to follow.
