Development and Build

Building Phala Blockchain requires specific dependencies and steps to ensure a successful build. Below is an overview of the process:


Phala Blockchain requires several system dependencies, Rust, Substrate dependencies, and LLVM 14.

System Dependencies

  • Ubuntu:
    apt install -y build-essential pkg-config libssl-dev protobuf-compiler
  • macOS:
    brew install protobuf
  • Protobuf Installation: Detailed installation options are available on the gRPC documentation page.


Install Rust using the following command:

curl -sSf | sh

Substrate Dependencies

Initialize Substrate dependencies:

git submodule update --init


Install LLVM 14:

chmod +x 14

Building the Blockchain

Ensure you have Rust and LLVM 14 installed. Note for macOS users: you will also need llvm and binutils from Homebrew or MacPort, and ensure their binaries are added to your $PATH.

Fetch submodules before building if you haven't used the --recursive option when cloning the repository:

git submodule update --init

Build the project:

cargo build --release
