⚡ Prefer a one-liner script (recommended)?

wget https://raw.githubusercontent.com/depinspirationhub/beamnode/main/node_install.sh && chmod +x node_install.sh && ./node_install.sh

🛠 Prefer Manual Step-by-Step Setup?

✅ Step 1: Update Your Server & Install Dependencies

sudo apt-get update && sudo apt-get install -y wget tar screen jq curl

⬇️ Step 2: Download and Install AvalancheGo (Avalanche Node Software)

latest=$(curl -s https://api.github.com/repos/ava-labs/avalanchego/releases/latest | jq -r .tag_name) && \
wget -q https://github.com/ava-labs/avalanchego/releases/download/$latest/avalanchego-linux-amd64-$latest.tar.gz && \
tar -xzf avalanchego-linux-amd64-$latest.tar.gz && \
sudo mv avalanchego-$latest/* /usr/local/bin/ && \
sudo chmod +x /usr/local/bin/avalanchego && \
rm -rf avalanchego-$latest avalanchego-linux-amd64-$latest.tar.gz

🧱 Step 3: Install Beam’s Subnet-EVM Binary

mkdir -p ~/subnetevm ~/.avalanchego/plugins ~/.avalanchego/configs && \
cd ~/subnetevm && \
subnetevm_latest=$(curl -s https://api.github.com/repos/ava-labs/subnet-evm/releases/latest | jq -r .tag_name) && \
wget -q https://github.com/ava-labs/subnet-evm/releases/download/${subnetevm_latest}/subnet-evm_${subnetevm_latest#v}_linux_amd64.tar.gz && \
tar -xzf subnet-evm_${subnetevm_latest#v}_linux_amd64.tar.gz && \
mv subnet-evm ~/.avalanchego/plugins/kLPs8zGsTVZ28DhP1VefPCFbCgS7o5bDNez8JUxPVw9E6Ubbz

⚙️ Step 4: Create Configuration Files

echo '{ "track-subnets": "eYwmVU67LmSfZb1RwqCMhBYkFyG8ftxn6jAwqzFmxC9STBWLC", "partial-sync-primary-network": true }' > ~/.avalanchego/configs/node.json && \
mkdir -p ~/.avalanchego/configs/chains/2tmrrBo1Lgt1mzzvPSFt73kkQKFas5d1AP88tv9cicwoFp8BSn && \
cd ~/.avalanchego/configs/chains/2tmrrBo1Lgt1mzzvPSFt73kkQKFas5d1AP88tv9cicwoFp8BSn && \
wget -q https://raw.githubusercontent.com/BuildOnBeam/beam-subnet/main/subnets/beam-mainnet/upgrade.json

🛠️ Step 5: Create Systemd Service to Auto-Start the Node

sudo tee /etc/systemd/system/beamnode.service > /dev/null <<EOF
[Unit]
Description=Beam Node
After=network.target

[Service]
User=root
ExecStart=/usr/local/bin/avalanchego --track-subnets=eYwmVU67LmSfZb1RwqCMhBYkFyG8ftxn6jAwqzFmxC9STBWLC
Restart=always
RestartSec=10

[Install]
WantedBy=multi-user.target
EOF

▶️ Step 6: Start the Beam Node

sudo systemctl daemon-reexec && \
sudo systemctl daemon-reload && \
sudo systemctl enable beamnode && \
sudo systemctl restart beamnode

⏳ Step 7: Wait a Bit for Node to Start

sleep 10

📡 Step 8: Get Your Validator Node Details

NODE_INFO=$(curl -s -X POST --data '{ "jsonrpc":"2.0", "id":1, "method":"info.getNodeID", "params":{} }' \
-H 'Content-Type: application/json' 127.0.0.1:9650/ext/info) && \
NODE_ID=$(echo "$NODE_INFO" | jq -r .result.nodeID) && \
BLS_KEY=$(echo "$NODE_INFO" | jq -r .result.nodePOP.publicKey) && \
BLS_PROOF=$(echo "$NODE_INFO" | jq -r .result.nodePOP.proofOfPossession) && \
echo "\nNode ID: $NODE_ID" && \
echo "BLS Public Key: $BLS_KEY" && \
echo "Proof of Possession: $BLS_PROOF"

💾 Step 9: Save Validator Info to File

echo -e "Node ID: $NODE_ID\nBLS Public Key: $BLS_KEY\nProof of Possession: $BLS_PROOF" > ~/beam-node-info.txt

📈 Step 10: Monitor Node Logs

journalctl -u beamnode -f

🔍 Step 11: Check Node Sync Status

To inspect the L1 sync status of your node, use the following command:

curl -X POST --data '{
"jsonrpc": "2.0",
"method": "platform.getBlockchainStatus",
"params":{
"blockchainID":"2tmrrBo1Lgt1mzzvPSFt73kkQKFas5d1AP88tv9cicwoFp8BSn"
},
"id": 1
}' -H 'content-type:application/json;' 127.0.0.1:9650/ext/bc/P

To check if your node has fully bootstrapped and is ready to be added as a validator, run:

curl -X POST --data '{ 
  "jsonrpc":"2.0", 
  "id":1, 
  "method": "info.isBootstrapped", 
  "params": {
    "chain": "2tmrrBo1Lgt1mzzvPSFt73kkQKFas5d1AP88tv9cicwoFp8BSn"
  }
}' -H 'content-type:application/json;' 127.0.0.1:9650/ext/info

📝 Step 12: Register Your Validator Node

Once your node is fully synced with the Beam network, you can proceed with registration.
Check the video above for a walkthrough, or refer to the official documentation for step-by-step instructions.

🎉 Congrats! You’re now running a Beam node on Avalanche!
