Install Rust

Linux/macOS

# Install Rust via rustup
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

# Follow the prompts, then reload your shell
source $HOME/.cargo/env

# Verify installation
rustc --version
cargo --version

Windows

Download and run rustup-init.exe.

Additional Components

# Add clippy for linting
rustup component add clippy

# Add rustfmt for formatting
rustup component add rustfmt

---

Install Python

Linux (Ubuntu/Debian)

sudo apt update
sudo apt install python3 python3-pip python3-venv

macOS

# Using Homebrew
brew install python@3.11

# Or use pyenv for version management
brew install pyenv
pyenv install 3.11
pyenv global 3.11

Python Dependencies

# Create virtual environment (recommended)
python3 -m venv .venv
source .venv/bin/activate

# Install ML dependencies
pip install torch transformers numpy scipy

---

Install Protocol Buffers

Linux (Ubuntu/Debian)

sudo apt install protobuf-compiler libprotobuf-dev

macOS

brew install protobuf

Verify Installation

protoc --version
# Should output: libprotoc 3.x.x or higher

---

Install System Dependencies

Linux (Ubuntu/Debian)

# Build essentials
sudo apt install build-essential pkg-config

# OpenSSL development headers
sudo apt install libssl-dev

# Additional dependencies
sudo apt install cmake clang

macOS

# Xcode command line tools
xcode-select --install

# OpenSSL (if needed)
brew install openssl

---

Clone the Repository

# Clone the repository
git clone https://github.com/neurochainai/ncn-network-v2-rs.git
cd ncn-network-v2-rs

---

Build the Project

# Build all components in debug mode
cargo build

# Build all components in release mode
cargo build --release

# Build specific component
cargo build -p gateway_node
cargo build -p compute_node
cargo build -p p2p_registry_node
cargo build -p test_client

Expected Output

   Compiling common_types v0.1.0
   Compiling p2p_registry_node v0.1.0
   Compiling gateway_node v0.1.0
   Compiling compute_node v0.1.0
   Compiling test_client v0.1.0
    Finished dev [unoptimized + debuginfo] target(s) in X.XXs

---

Verify Installation

Run Tests

# Run all tests
cargo test --all

# Run tests with output
cargo test --all -- --nocapture

Check Linting

# Run clippy
cargo clippy --all

# Run format check
cargo fmt --all -- --check

---

Optional: Docker Setup

Install Docker

# Linux
curl -fsSL https://get.docker.com | sh
sudo usermod -aG docker $USER

# macOS
brew install --cask docker

Build Docker Images

# Build all images
docker-compose build

# Or build individual images
docker build -t ncn-gateway -f gateway_node/Dockerfile .
docker build -t ncn-compute -f compute_node/Dockerfile .
docker build -t ncn-registry -f p2p_registry_node/Dockerfile .

---

Optional: Foundry Setup

For smart contract development:

# Install Foundry
curl -L https://foundry.paradigm.xyz | bash
foundryup

# Verify
forge --version
cast --version
anvil --version

---

IDE Setup

VS Code

Recommended extensions:

{
  "recommendations": [
    "rust-lang.rust-analyzer",
    "tamasfe.even-better-toml",
    "serayuzgur.crates",
    "vadimcn.vscode-lldb",
    "ms-python.python"
  ]
}

JetBrains (IntelliJ/CLion)

• Install Rust plugin

• Install Python plugin

• Configure Cargo toolchain

---

Environment Variables

Create a .env file or export variables:

# Logging
export RUST_LOG=info
export RUST_BACKTRACE=1

# Development mode
export REQUIRE_PAYMENT=false
export SANDBOX_MODE=disabled

# Network (local development)
export RPC_URL=http://127.0.0.1:8545

---

Troubleshooting

"linker not found"

# Install build essentials
sudo apt install build-essential

"protoc not found"

# Install protobuf compiler
sudo apt install protobuf-compiler

"OpenSSL not found"

# Linux
sudo apt install libssl-dev pkg-config

# macOS
brew install openssl
export OPENSSL_DIR=$(brew --prefix openssl)

"Python not found" during build

# Ensure Python is in PATH
which python3

# Or set explicitly
export PYTHON_SYS_EXECUTABLE=$(which python3)
