Crowd Control: Installing and working with a node

25.09.2024, 15:45

Crowd Control is a blockchain-based collectible card game where players can create their own cards and interact with others in the ecosystem. This article provides detailed instructions on how to install and configure a node for the Crowd Control testnet.

Minimum System Requirements:

Node type: Testnet
CPU: 4
RAM: 8gb
Storage: 150gb

Automatic node installation

You can use autoscript to simplify the installation process:

wget -O crowd https://raw.githubusercontent.com/111STAVR111/props/main/Crowd/crowd && chmod +x crowd && ./crowd

Manual node installation

Server preparation

First, you need to update and install all the necessary packages on the server:

sudo apt update && sudo apt upgrade -y
sudo apt install curl tar wget clang pkg-config libssl-dev jq build-essential bsdmainutils git make ncdu gcc chrony liblz4-tool -y

Installing Go 1.21.6

ver="1.21.6"
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" >> $HOME/.bash_profile
source $HOME/.bash_profile
go version

Cardchaind build 11.07.24

cd $HOME && mkdir -p go/bin/
git clone https://github.com/DecentralCardGame/Cardchain
wget -O Cardchaind https://github.com/DecentralCardGame/Cardchain/releases/download/v0.16.0/cardchaind
chmod +x Cardchaind
mv $HOME/Cardchaind /usr/local/bin
Cardchaind version --long | grep -e commit -e version

Check the version:

version: 0.16.0
commit: be4d9f600b2274bf9dce0ec944c3ba175fa7db8e

Initialization

Initialize the node by specifying a name and network ID:

Cardchaind init <your_node_name> --chain-id cardtestnet-12
Cardchaind config chain-id cardtestnet-12

Creating or restoring a wallet

Cardchaind keys add <walletname>
Cardchaind keys add <walletname> --recover

Genesis Download

Download the genesis file to synchronize with the network:

wget -O $HOME/.cardchaind/config/genesis.json "https://cardchain.crowdcontrol.network/files/genesis.json"
sha256sum $HOME/.cardchaind/config/genesis.json

Check the hash:

1aedb68136b19f16edfe9c7e4e73a38f0fbc93cb13c555ca29b3493b40facc58

Setting the minimum gas cost, peers and other parameters

sed -i.bak -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0.0ubpf\"/;" ~/.cardchaind/config/app.toml
external_address=$(wget -qO- eth0.me)
sed -i.bak -e "s/^external_address *=.*/external_address = \"$external_address:26656\"/" $HOME/.cardchaind/config/config.toml
peers="86b643ba743ccc78e6e086120d43c96f85872601@202.61.225.157:20656"
sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$peers\"/" $HOME/.cardchaind/config/config.toml

Pruning setup (optional)

Pruning can be configured to optimize data storage:

pruning="custom"
pruning_keep_recent="1000"
pruning_keep_every="0"
pruning_interval="10"
sed -i -e "s/^pruning *=.*/pruning = \"$pruning\"/" $HOME/.cardchaind/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"$pruning_keep_recent\"/" $HOME/.cardchaind/config/app.toml

Indexer (optional)

indexer="null" &&
sed -i -e "s/^indexer *=.*/indexer = \"$indexer\"/" $HOME/.cardchaind/config/config.toml

Download addrbook

wget -O $HOME/.cardchaind/config/addrbook.json "https://raw.githubusercontent.com/111STAVR111/props/main/Crowd/addrbook.json"

Creating a service file

Create a service file to automatically start the node:

sudo tee <<EOF >/dev/null /etc/systemd/system/Cardchaind.service
[Unit]
Description=Cardchain Daemon
After=network-online.target
[Service]
User=$USER
ExecStart=$(which Cardchaind) start
Restart=always
RestartSec=10
LimitNOFILE=65535
[Install]
WantedBy=multi-user.target
EOF

Testnet's SnapShot is updated every 5 hours

cd $HOME
apt install lz4
sed -i.bak -E "s|^(enable[[:space:]]+=[[:space:]]+).*$|\1false|" ~/.cardchaind/config/config.toml
sudo systemctl stop Cardchaind
cp $HOME/.cardchaind/data/priv_validator_state.json $HOME/.cardchaind/priv_validator_state.json.backup
rm -rf $HOME/.cardchaind/data

wget -O $HOME/.cardchaind/config/addrbook.json "https://raw.githubusercontent.com/111STAVR111/props/main/Crowd/addrbook.json"
sudo systemctl restart Cardchaind && journalctl -u Cardchaind -f -o cat

Starting a node

Now you can run the node and monitor its status:

sudo systemctl daemon-reload
sudo systemctl enable Cardchaind
sudo systemctl restart Cardchaind && sudo journalctl -u Cardchaind -f -o cat

Creating a validator

When the node is synchronized, create a validator:

Cardchaind tx staking create-validator \
--amount 1000000ubpf \
--from <walletName> \
--commission-max-change-rate "0.2" \
--commission-max-rate "1" \
--commission-rate "0.1" \
--min-self-delegation "1" \
--details="" \
--identity="" \
--pubkey $(Cardchaind tendermint show-validator) \
--moniker <validator_name> \
--fees 300ubpf \
--chain-id cardtestnet-12 -y

Delete a node

sudo systemctl stop Cardchaind
sudo rm /etc/systemd/system/Cardchaind.service
sudo rm -rf $HOME/.cardchaind/
sudo rm -rf Testnet
sudo rm -rf $(which Cardchaind)
