Local Testnet with 2 Validator

  1. Setting up two chains

    # change HOME1 & HOME2 for proper value
KEY1="key1"
KEY2="key2"
CHAINID="canto_7700-1"
MONIKER1="canto1"
MONIKER2="canto2"
KEYRING="test"
KEYALGO="eth_secp256k1"
HOME1="$HOME/workspace/canto1"
HOME2="$HOME/workspace/canto2"

rm -rf $HOME1
rm -rf $HOME2

# initialize two chains
cantod init $MONIKER1 --chain-id $CHAINID --home $HOME1
cantod init $MONIKER2 --chain-id $CHAINID --home $HOME2

# Setting up keys 
cantod keys add $KEY1 --keyring-backend $KEYRING --algo $KEYALGO --home $HOME1
cantod keys add $KEY2 --keyring-backend $KEYRING --algo $KEYALGO --home $HOME2

# Allocate genesis accounts (cosmos formatted addresses)
cantod add-genesis-account $KEY1 1000000000000000000000000000000000acanto --keyring-backend $KEYRING --home $HOME1

# Update total supply with claim values
#validators_supply=$(cat $HOME1/config/genesis.json | jq -r '.app_state["bank"]["supply"][0]["amount"]')
# Bc is required to add this big numbers
# total_supply=$(bc <<< "$amount_to_claim+$validators_supply")
total_supply=1000000000000000000000000000000000
cat $HOME1/config/genesis.json | jq -r --arg total_supply "$total_supply" '.app_state["bank"]["supply"][0]["amount"]=$total_supply' > $HOME1/config/tmp_genesis.json && mv $HOME1/config/tmp_genesis.json $HOME1/config/genesis.json

echo $KEYRING
echo $KEY1
# Sign genesis transaction
mkdir $HOME1/config/gentx
cantod gentx $KEY1 900000000000000000000000acanto --keyring-backend $KEYRING --chain-id $CHAINID --output-document $HOME1/config/gentx/gentx-1.json --home $HOME1

# Collect genesis tx
cantod collect-gentxs --home $HOME1

# Run this to ensure everything worked and that the genesis file is setup correctly
cantod validate-genesis --home $HOME1

  2. Copy genesis file from chain 1 to chain 2

    cp $HOME1/config/genesis.json $HOME2/config/genesis.json

  3. Change configs for chain 2 (changing ports) (path: $HOME2/config/)

    #app.toml
address = "tcp://0.0.0.0:1317"  --> address = "tcp://0.0.0.0:11317"
address = ":8080" --> address = ":9080"
address = "0.0.0.0:9090" --> address = "0.0.0.0:19090"
address = "0.0.0.0:9091" --> address = "0.0.0.0:19091"
address = "0.0.0.0:8545" --> address = "0.0.0.0:18545"
ws-address = "0.0.0.0:8546" --> ws-address = "0.0.0.0:18546"

#client.toml
node = "tcp://localhost:26657" --> node = "tcp://localhost:36657"

# config.toml
proxy_app = "tcp://127.0.0.1:26658" --> proxy_app = "tcp://127.0.0.1:36658"
laddr = "tcp://127.0.0.1:26657" --> laddr = "tcp://127.0.0.1:36657"
pprof_laddr = "localhost:6060" --> pprof_laddr = "localhost:16060"
laddr = "tcp://0.0.0.0:26656" --> laddr = "tcp://0.0.0.0:36656"
prometheus_listen_addr = ":26660" --> prometheus_listen_addr = ":36660"

  4. Setup persistent peer (for chain 2)

    echo $(cantod tendermint show-node-id --home $HOME1)'@0.0.0.0:26656'
25839f2ef44109c5d7de0d0cf6267d9679949e72@0.0.0.0:26656

# copy printed value to persistent-peer value in config.toml
persistent_peers = "25839f2ef44109c5d7de0d0cf6267d9679949e72@0.0.0.0:26656"

  5. Start chains in new terminals

    cantod start --home $HOME/workspace/canto1
cantod start --home $HOME/workspace/canto2

  6. Send tokens to key2 account (2nd validator)

    DST=$(cantod keys show $KEY2 --home $HOME2 --keyring-backend $KEYRING -a)
cantod tx bank send $KEY1 $DST 100000000000000000000000000000000acanto --from $KEY1 --home $HOME1 --keyring-backend $KEYRING --chain-id $CHAINID

  7. Create a new validator

    cantod tx staking create-validator \
  --amount=10000000000000000000000000000000acanto \
  --pubkey=$(cantod tendermint show-validator --home $HOME2) \
  --chain-id=$CHAINID \
  --commission-rate="0.10" \
  --commission-max-rate="0.20" \
  --commission-max-change-rate="0.01" \
  --min-self-delegation="1000000" \
  --gas="100000000" \
  --gas-prices="200000000000acanto" \
  --from=$KEY2 \
  --home=$HOME2 \
  --keyring-backend=$KEYRING --broadcast-mode block

  8. Query validators

    cantod q staking validators --home $HOME1
