Installation

If you want to setup Composable fullnode manually follow the steps below

Update and upgrade

sudo apt update && sudo apt upgrade -y

Install GO

if ! [ -x "$(command -v go)" ]; then
  ver="1.19.3"
  cd $HOME
  wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz"
  sudo rm -rf /usr/local/go
  sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz"
  rm "go$ver.linux-amd64.tar.gz"
  echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> ~/.bash_profile
  source ~/.bash_profile
fi

Install node

cd $HOME
rm -rf composable-centauri
git clone https://github.com/notional-labs/composable-centauri.git
cd composable-centauri
git checkout v7.0.3
make install

Setting up vars

You should replace values in <> <YOUR_MONIKER> Here you should put name of your moniker (validator) that will be visible in explorer <YOUR_WALLET> Here you shoud put the name of your wallet

COMPOSABLE_WALLET="<YOUR_WALLET_NAME>"
COMPOSABLE_NODENAME="<YOUR_MONIKER>"
COMPOSABLE_CHAIN_ID="banksy-testnet-5"
echo "
export COMPOSABLE_WALLET=${COMPOSABLE_WALLET}
export COMPOSABLE_NODENAME=${COMPOSABLE_NODENAME}
export COMPOSABLE_CHAIN_ID=${COMPOSABLE_CHAIN_ID}
" >> $HOME/.bash_profile

source $HOME/.bash_profile

Configure your node

picad config chain-id ${COMPOSABLE_CHAIN_ID}

Initialize your node

picad init ${COMPOSABLE_NODENAME} --chain-id ${COMPOSABLE_CHAIN_ID}

Download genesis & addrbook

curl -Ls "https://snapshots.l0vd.com/composable-testnet/genesis.json" > $HOME/.banksy/config/genesis.json
curl -Ls "https://snapshots.l0vd.com/composable-testnet/addrbook.json" > $HOME/.banksy/config/addrbook.json

(OPTIONAL) Set custom ports

If you want to use non-default ports

COMPOSABLE_PORT=<SET_CUSTOM_PORT> #Example: COMPOSABLE_PORT=56 (numbers from 1 to 64)
sed -i.bak -e "s%^proxy_app = \"tcp://127.0.0.1:26658\"%proxy_app = \"tcp://127.0.0.1:${COMPOSABLE_PORT}658\"%; s%^laddr = \"tcp://127.0.0.1:26657\"%laddr = \"tcp://127.0.0.1:${COMPOSABLE_PORT}657\"%; s%^pprof_laddr = \"localhost:6060\"%pprof_laddr = \"localhost:${COMPOSABLE_PORT}060\"%; s%^laddr = \"tcp://0.0.0.0:26656\"%laddr = \"tcp://0.0.0.0:${COMPOSABLE_PORT}656\"%; s%^prometheus_listen_addr = \":26660\"%prometheus_listen_addr = \":${COMPOSABLE_PORT}660\"%" /$HOME/.banksy/config/config.toml
sed -i.bak -e "s%^address = \"tcp://0.0.0.0:1317\"%address = \"tcp://0.0.0.0:${COMPOSABLE_PORT}317\"%; s%^address = \"tcp://localhost:1317\"%address = \"tcp://0.0.0.0:${COMPOSABLE_PORT}317\"%; s%^address = \":8080\"%address = \":${COMPOSABLE_PORT}080\"%; s%^address = \"0.0.0.0:9090\"%address = \"0.0.0.0:${COMPOSABLE_PORT}090\"%; s%^address = \"localhost:9090\"%address = \"localhost:${COMPOSABLE_PORT}090\"%; s%^address = \"0.0.0.0:9091\"%address = \"0.0.0.0:${COMPOSABLE_PORT}091\"%; s%^address = \"localhost:9091\"%address = \"localhost:${COMPOSABLE_PORT}091\"%; s%^address = \"0.0.0.0:8545\"%address = \"0.0.0.0:${COMPOSABLE_PORT}545\"%; s%^ws-address = \"0.0.0.0:8546\"%ws-address = \"0.0.0.0:${COMPOSABLE_PORT}546\"%" /$HOME/.banksy/config/app.toml

Set seeds and peers

PEERS="@composable-testnet.peers.l0vd.com:"
sed -i -e "s/^seeds *=.*/seeds = \"$SEEDS\"/; s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" $HOME/.banksy/config/config.toml

Config pruning

pruning="custom"
pruning_keep_recent="100"
pruning_keep_every="0"
pruning_interval="50"
sed -i -e "s/^pruning *=.*/pruning = \"$pruning\"/" $HOME/.banksy/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"$pruning_keep_recent\"/" $HOME/.banksy/config/app.toml
sed -i -e "s/^pruning-keep-every *=.*/pruning-keep-every = \"$pruning_keep_every\"/" $HOME/.banksy/config/app.toml
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"$pruning_interval\"/" $HOME/.banksy/config/app.toml

Set minimum gas price and null indexer

sed -i -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0ppica\"/" $HOME/.banksy/config/app.toml
sed -i -e "s/^indexer *=.*/indexer = \"null\"/" $HOME/.banksy/config/config.toml

Create Service

sudo tee /etc/systemd/system/picad.service > /dev/null <<EOF
[Unit]
Description=Composable testnet
After=network-online.target

[Service]
User=$USER
ExecStart=$(which picad) start
Restart=on-failure
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

Reset blockchain info and restart your node

sudo systemctl daemon-reload
sudo systemctl enable picad
picad tendermint unsafe-reset-all --home $HOME/.banksy --keep-addr-book
sudo systemctl restart picad && sudo journalctl -u picad -f -o cat

(OPTIONAL) Use State Sync

Starting a validator

1. Add a new key

picad keys add ${COMPOSABLE_WALLET}

(OR)

1. Recover your key

picad keys add ${COMPOSABLE_WALLET} --recover
COMPOSABLE_WALLET_ADDR=$(picad keys show ${COMPOSABLE_WALLET} -a)
echo "export COMPOSABLE_WALLET_ADDR=${COMPOSABLE_WALLET_ADDR}" >> $HOME/.bash_profile

source $HOME/.bash_profile

2. Create validator

Wait until the node is synchronized.

picad tx staking create-validator \
--amount 1000000ppica \
--commission-max-change-rate "0.01" \
--commission-max-rate "0.20" \
--commission-rate "0.1" \
--min-self-delegation "1" \
--details "" \
--pubkey $(picad tendermint show-validator) \
--moniker ${COMPOSABLE_NODENAME} \
--chain-id ${COMPOSABLE_CHAIN_ID} \
--from ${COMPOSABLE_WALLET_ADDR} \
--gas-prices 0ppica \
--gas-adjustment 1.5 \
--gas auto \
--yes
