Setting up the Node​

Initialization node​

Please choose your MONIKER name, it will represent your node

junod init MONIKER_NAME --chain-id juno-1

This will generate severals files in ~/.juno/config/

  • node_key.json
  • genesis.json
  • priv_validator_key.json

Download and replace the genesis file​

rm ~/.juno/config/genesis.json 
wget https://download.dimi.sh/juno-phoenix2-genesis.tar.gz 
tar -xvf juno-phoenix2-genesis.tar.gz 
mv juno-phoenix2-genesis.json ~/.juno/config

Set minimum gas prices​

sed -i.bak -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0.0025ujuno,0.001ibc\/C4CFF46FD6DE35CA4CF4CE031E643C8FDC9BA4B99AE598E9B0ED98FE3A2319F9\"/" ~/.juno/config/app.toml

Node connexion​

In order to connect the node you can either use seeds, Lives peers or address book.

Set Seeds​

export SEEDS="$(curl -sL "https://raw.githubusercontent.com/CosmosContracts/mainnet/main/juno-1/seeds.txt")"
sed -i.bak -e "s/^seeds *=.*/seeds = \"$SEEDS\"/" ~/.juno/config/config.toml

Setup service file​
