Quick Start: Run a Node​

Prerequisites​

  • Go 1.24+ (download)
  • Ubuntu 24.04+ or equivalent Linux
  • Hardware: 4 CPU, 8 GB RAM, 200 GB SSD (minimum)

Option 1: Install from Source​

# Clone repository
git clone https://github.com/monolythium/mono-chain.git
cd mono-chain

# Checkout release
git checkout v0.1.0-rc0

# Build and install
make install
sudo mv $(go env GOPATH)/bin/monod /usr/local/bin/

# Verify
monod version

Initialize and Join​

# Initialize node
monod init my-node --chain-id mono_6940-1

# Download genesis
curl -s https://raw.githubusercontent.com/monolythium/networks/prod/testnet/genesis.json \
  -o ~/.mono/config/genesis.json

# Start
monod start

Your node will sync from genesis. This may take time depending on how many blocks have been produced.

Become a Validator​

After your node is fully synced:

# Create validator key
monod keys add validator --keyring-backend file

# You need at least 200,000 LYTH:
# - 100,000 LYTH for registration burn
# - 100,000 LYTH for minimum self-delegation

# Create validator
monod tx staking create-validator \
  --amount 100000000000000000000000alyth \
  --pubkey $(monod comet show-validator) \
  --moniker "my-validator" \
  --chain-id mono_6940-1 \
  --commission-rate 0.10 \
  --commission-max-rate 0.20 \
  --commission-max-change-rate 0.01 \
  --min-self-delegation 100000000000000000000000 \
  --from validator \
  --keyring-backend file \
  --gas auto \
  --gas-adjustment 1.5
