Download chain configuration and genesis file

• Mainnet

#config.toml
sudo curl https://raw.githubusercontent.com/bitkub-chain/bkc-node/v2.1.0/mainnet/config.toml --create-dirs -o "/bkc-node/mainnet/config.toml"

#genesis.json
sudo curl https://raw.githubusercontent.com/bitkub-chain/bkc-node/v2.1.0/mainnet/genesis.json --create-dirs -o "/bkc-node/mainnet/genesis.json"

• Testnet

#config.toml
sudo curl https://raw.githubusercontent.com/bitkub-chain/bkc-node/v2.1.0/testnet/config.toml --create-dirs -o "/bkc-node/testnet/config.toml"

#genesis.json
sudo curl https://raw.githubusercontent.com/bitkub-chain/bkc-node/v2.1.0/testnet/genesis.json --create-dirs -o "/bkc-node/testnet/genesis.json"

Initialize a genesis file

#Mainnet
geth --datadir /bkc-node/mainnet/data init /bkc-node/mainnet/genesis.json

#Testnet
geth --datadir /bkc-node/testnet/data init /bkc-node/testnet/genesis.json

Create system service/unit file

sudo nano /etc/systemd/system/geth.service

Furthermore, copy and paste the code below

geth.service

[Unit]
Description=BKC ValidatorNode
After=network.target auditd.service
Wants=network.target

Important Configuration

--datadir <DIRECTORY_LOCATION>

The directory to store the chain data e.g., mainnet: /bkc-node/mainnet/data testnet: /bkc-node/testnet/data

--config <CONFIG_FILE>

The location of the toml config file e.g.,

mainnet: /bkc-node/mainnet/config.toml

testnet: /bkc-node/testnet/config.toml

Enable and start the service

sudo systemctl daemon-reload
sudo systemctl enable geth
sudo systemctl start geth
