Zebra implements all the features required to reach Zcash network consensus, and the network stack is interoperable with `zcashd`. [Here](https://docs.rs/zebrad/latest/zebrad/index.html#zebra-advantages) are some benefits of Zebra. Zebra validates blocks and transactions, but needs extra software to generate them: - To generate transactions, [run Zebra with `lightwalletd`](https://zebra.zfnd.org/user/lightwalletd.html). - To generate blocks, use a mining pool or miner with Zebra's mining JSON-RPCs. Currently Zebra can only send mining rewards to a single fixed address. To distribute rewards, use mining software that creates its own distribution transactions, a light wallet or the `zcashd` wallet. Please [join us on Discord](https://discord.gg/na6QZNd) if you'd like to find out more or get involved! ## Getting Started You can run Zebra using our Docker image or you can build it manually. Please see the [System Requirements](https://zebra.zfnd.org/user/requirements.html) section in the Zebra book for system requirements. ### Docker This command will run our latest release, and sync it to the tip: ```sh docker run zfnd/zebra:latest ``` For more information, read our [Docker documentation](https://zebra.zfnd.org/user/docker.html). ### Manual Build Building Zebra requires [Rust](https://www.rust-lang.org/tools/install), [libclang](https://clang.llvm.org/doxygen/group__CINDEX.html), 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](https://github.com/ZcashFoundation/zebra/releases). Below are quick summaries for installing the dependencies on your machine. [//]: # "The empty line in the `summary` tag below is required for correct Markdown rendering."
#### General instructions for installing dependencies 1. Install [`cargo` and `rustc`](https://www.rust-lang.org/tools/install). 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`](https://grpc.io/docs/protoc-installation/)** > [!NOTE] > Zebra uses the `--experimental_allow_proto3_optional` flag with `protoc` > during compilation. This flag was introduced in [Protocol Buffers > v3.12.0](https://github.com/protocolbuffers/protobuf/releases/tag/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 ```sh 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: ```sh cargo install --locked zebrad ``` You can start Zebra by ```sh zebrad start ``` Refer to the [Installing Zebra](https://zebra.zfnd.org/user/install.html) and [Running Zebra](https://zebra.zfnd.org/user/run.html) sections in the book for enabling optional features, detailed configuration and further details. ## Documentation The Zcash Foundation maintains the following resources documenting Zebra: - The Zebra Book: - [General Introduction](https://zebra.zfnd.org/index.html), - [User Documentation](https://zebra.zfnd.org/user.html), - [Developer Documentation](https://zebra.zfnd.org/dev.html). - The [documentation of the public APIs](https://docs.rs/zebrad/latest/zebrad/#zebra-crates) for the latest releases of the individual Zebra crates. - The [documentation of the internal APIs](https://doc-internal.zebra.zfnd.org) for the `main` branch of the whole Zebra monorepo. ## User support For bug reports please [open a bug report ticket in the Zebra repository](https://github.com/ZcashFoundation/zebra/issues/new?assignees=&labels=C-bug%2C+S-needs-triage&projects=&template=bug_report.yml&title=%5BUser+reported+bug%5D%3A+).
