Arc Network Node Installation Guide

Arc is an open EVM-compatible Layer 1 blockchain built on Malachite consensus, delivering sub-second finality and USDC as native gas currency.

Hardware Requirements

Minimum Specifications

• CPU: 4 cores
• RAM: 16 GB
• Disk: 200 GB SSD (NVMe recommended)
• Network: 100 Mbps

Recommended Specifications

• CPU: 8+ cores
• RAM: 32 GB
• Disk: 500 GB+ NVMe SSD
• Network: 1 Gbps

Prerequisites

• Ubuntu 24.04 LTS (recommended)
• Rust toolchain (1.91.1+)
• Basic Linux system administration knowledge

Installation

Step 1: Install Rust

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source ~/.cargo/env

Step 2: Install System Dependencies

sudo apt update && sudo apt upgrade -y
sudo apt install -y libclang-dev pkg-config build-essential git curl

Step 3: Clone Arc Node Repository

git clone https://github.com/circlefin/arc-node.git
cd arc-node
git checkout v0.6.0
git submodule update --init --recursive

Step 4: Build Arc Node Binaries

⏱️ Build time: ~10-15 minutes depending on hardware.

cargo install --path crates/node
cargo install --path crates/malachite-app
cargo install --path crates/snapshots

Binaries will be installed to ~/.cargo/bin/:

• arc-node-execution — Execution layer (Reth-based)
• arc-node-consensus — Consensus layer (Malachite-based)
• arc-snapshots — Snapshot utility

Step 5: Create Data Directories

mkdir -p ~/.arc/execution ~/.arc/consensus

Step 6: Download Blockchain Snapshots

⚠️ Important: Snapshots are ~84 GB download, ~150 GB extracted. Requires stable internet and sufficient disk space.

arc-snapshots download --chain=arc-testnet \
  --execution-path ~/.arc/execution \
  --consensus-path ~/.arc/consensus

⏱️ Download time: 30-60 minutes. Extraction is CPU-intensive.

Step 7: Generate JWT Secret

openssl rand -hex 32 | tr -d "\n" > ~/.arc/jwt.hex
chmod 600 ~/.arc/jwt.hex

Step 8: Initialize Consensus Layer

arc-node-consensus init --home ~/.arc/consensus

Step 9: Create Systemd Services

Execution Layer Service

Create /etc/systemd/system/arc-execution.service:

[Unit]
Description=Arc Network Execution Layer
After=network.target

[Service]
Type=simple
User=YOUR_USERNAME
WorkingDirectory=/home/YOUR_USERNAME/arc-node
ExecStart=/home/YOUR_USERNAME/.cargo/bin/arc-node-execution node \
  --chain arc-testnet \
  --datadir /home/YOUR_USERNAME/.arc/execution \
  --http --http.port 8545 --http.addr 0.0.0.0 \
  --authrpc.port 8551 \
  --authrpc.jwtsecret /home/YOUR_USERNAME/.arc/jwt.hex \
  --port 31000
Restart=on-failure
RestartSec=10
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target

Consensus Layer Service

Create /etc/systemd/system/arc-consensus.service:

[Unit]
Description=Arc Network Consensus Layer
After=network.target arc-execution.service
Requires=arc-execution.service

[Service]
Type=simple
User=YOUR_USERNAME
WorkingDirectory=/home/YOUR_USERNAME/arc-node
ExecStart=/home/YOUR_USERNAME/.cargo/bin/arc-node-consensus start \
  --home /home/YOUR_USERNAME/.arc/consensus \
  --eth-rpc-endpoint http://localhost:8545 \
  --execution-endpoint http://localhost:8551 \
  --execution-jwt /home/YOUR_USERNAME/.arc/jwt.hex \
  --rpc.addr 127.0.0.1:31000 \
  --follow \
  --follow.endpoint https://rpc.drpc.testnet.arc.network,wss=rpc.drpc.testnet.arc.network \
  --follow.endpoint https://rpc.quicknode.testnet.arc.network,wss=rpc.quicknode.testnet.arc.network \
  --follow.endpoint https://rpc.blockdaemon.testnet.arc.network,wss=rpc.blockdaemon.testnet.arc.network
Restart=on-failure
RestartSec=10
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target

⚠️ Replace YOUR_USERNAME with your actual username.

Step 10: Start Services

sudo systemctl daemon-reload
sudo systemctl enable arc-execution arc-consensus
sudo systemctl start arc-execution
sleep 10
sudo systemctl start arc-consensus

Step 11: Verify Operation

Check status:

sudo systemctl status arc-execution arc-consensus

Check current block:

curl -s -X POST -H 'Content-Type: application/json' \
  --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' \
  http://localhost:8545 | jq -r '.result' | xargs printf "%d\n"

View logs:

sudo journalctl -u arc-consensus -f
