Run a Node

Guideline to run a full node on DERA chain

Dependencies

• Ubuntu 22.04

• GCC

• Go v1.23.6

• A public static IP

Build the Node binary

1. Clone the AvalancheGo repository

git clone https://github.com/ava-labs/avalanchego.git

1. Compile binary

cd avalanchego
./scripts/build.sh

1. Create AvalancheGo service directory

sudo mkdir /var/lib/avalanchego

1. Copy executable to binary directory

sudo cp avalanchego/build/avalanchego /usr/local/bin/
sudo chmod 755 /usr/local/bin/avalanchego

1. Create AvalancheGo working directory

sudo mkdir /root/.avalanchego
sudo mkdir -p /root/.avalanchego/plugins

1. Download the subnet EVM from official repository

wget https://github.com/ava-labs/subnet-evm/releases/download/v0.7.3/subnet-evm_0.7.3_linux_amd64.tar.gz
tar -xzvf subnet-evm_0.7.3_linux_amd64.tar.gz

1. Copy subnet EVM to AvalancheGo working directory

sudo cp subnet-evm_0.7.3_linux_amd64/subnet-evm /root/.avalanchego/plugins/mDVK6hF1rcPB2e7ftmYbMQgnYMnQSnnk7cUfu8dENAYqH9XJA

mDVK6hF1rcPB2e7ftmYbMQgnYMnQSnnk7cUfu8dENAYqH9XJA is the VMID of DERA chain.

1. Create chainConfigs directory

sudo mkdir -p /root/.avalanchego/chainConfigs/2XCTEc8CfNK9MtQWYMfgNt32QjZsZqq92LH7eTV5xY8YjY44du

2XCTEc8CfNK9MtQWYMfgNt32QjZsZqq92LH7eTV5xY8YjY44du is blockchain ID of DERA chain.

1. Create chain config.json

sudo touch /root/.avalanchego/chainConfigs/2XCTEc8CfNK9MtQWYMfgNt32QjZsZqq92LH7eTV5xY8YjY44du/config.json

with content.

{
  "database-type": "leveldb",
  "log-level": "debug",
  "warp-api-enabled": true,
  "eth-apis": [
    "eth",
    "eth-filter",
    "net",
    "admin",
    "web3",
    "internal-eth",
    "internal-blockchain",
    "internal-transaction",
    "internal-debug",
    "internal-account",
    "internal-personal"
  ]
}

1. Create config.json for AvalancheGo

sudo touch /root/.avalanchego/config.json

with content.

{
    "chain-config-dir": "/root/.avalanchego/chainConfigs",
    "http-allowed-hosts": "*",
    "http-host": "0.0.0.0",
    "network-allow-private-ips": "true",
    "public-ip": "YOUR_PUBLIC_IP",
    "track-subnets": "B7hA9WibSJu2fKdHT2XZs2RYg1rZTtxwg6cMYBKYjvcJjbqsp"
}

1. Create systemd startup scripts

sudo touch /etc/systemd/system/avalanchego.service

with content.

[Unit]
Description=AvalancheGo node
After=network.target

[Service]
User=root
ExecStart=/usr/local/bin/avalanchego --config-file /root/.avalanchego/config.json
WorkingDirectory=/var/lib/avalanchego
Restart=always
RestartSec=3
LimitNOFILE=65535
LimitNPROC=65535
LimitMEMLOCK=infinity

[Install]
WantedBy=multi-user.target

1. Load the systemd service

sudo systemctl daemon-reload

1. Start and enable the AvalancheGo service

sudo systemctl start avalanchego
sudo systemctl enable avalanchego

1. Tracking the bootstrap process, until the node is fully bootstrapped

sudo journalctl -u avalanchego

1. Verify node is fully bootstrapped

• DERA chain

curl -X POST --data '{
    "jsonrpc":"2.0",
    "id"     :1,
    "method" :"info.isBootstrapped",
    "params": {
        "chain":"2XCTEc8CfNK9MtQWYMfgNt32QjZsZqq92LH7eTV5xY8YjY44du"
    }
}' -H 'content-type:application/json;' 127.0.0.1:9650/ext/info

• P-chain

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

Ensure that both requests response are

{"jsonrpc":"2.0","result":{"isBootstrapped":true},"id":1}

Then your node is ready to work to secure DERA chain consensus.
