OKP4 | Testnet - установка ноды



Server requirements:

• 2 CPU
• 8 RAM
• 200 GB storage

Prepare server:

Update system dependencies:

sudo apt update

sudo apt install

Install go (version 19+ is needed)

wget -c https://golang.org/dl/go1.19.2.linux-amd64.tar.gz
sudo tar -C /usr/local -xvzf go1.19.2.linux-amd64.tar.gz
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export GO111MODULE=on
export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin
source ~/.profile
go version
rm -rf go1.19.2.linux-amd64.tar.gz

Install make, zip and jq:

apt install make unzip jq git

Node installation:

mkdir okp4
#make directory okp4

cd okp4
#go to the directory okp4

wget -P /root/okp4 https://github.com/okp4/okp4d/archive/refs/heads/main.zip
#download the repository

unzip main.zip
#unzip main.zip

rm main.zip
#delete zip

cd okp4d-main
#go to the directory okp4d-main

sudo apt install build-essential

make build install

okp4d version

CHAIN_ID=okp4-nemeton-1
#declare a variable

MONIKER="SmartHamster"
#change SmartHamster on your name of node

okp4d init $MONIKER --chain-id $CHAIN_ID
#initialize the node

Change genesis:

cd /root/.okp4d/config

rm genesis.json
 
wget genesis.json https://raw.githubusercontent.com/okp4/networks/main/chains/nemeton-1/genesis.json

Add peers:

PEERS="[email protected]:36656,[email protected]:36656,[email protected]:36656,[email protected]:26656,[email protected]:36656,[email protected]:26656,[email protected]:17656,[email protected]:31656,[email protected]:21656,[email protected]:28656,[email protected]:51656,[email protected]:26656,[email protected]:26646,[email protected]:26656,[email protected]:33656,[email protected]:36656"

sed -i -e "s/^seeds *=.*/seeds = \"$SEEDS\"/; s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" $HOME/.okp4d/config/config.toml

Start the node:

okp4d start

Now the node does not work as a service, we need to create a service file so that it worked in the background when we close the terminal:

sudo tee /etc/systemd/system/okp4d.service > /dev/null <<EOF

Next, copy as one command:

[Unit]
Description=Okp4 Node
After=network.target
[Service]
User=$USER
Type=simple
ExecStart=/root/go/bin/okp4d start
Restart=on-failure
LimitNOFILE=65535
[Install]
WantedBy=multi-user.target
EOF

Copying the executable:

cd okp4/okp4d-main
sudo cp ./target/dist/okp4d /usr/local/bin/ || exit

Run the service file:

sudo systemctl daemon-reload

sudo systemctl enable okp4d

sudo systemctl restart okp4d

sudo systemctl status okp4d

View logs:

journalctl -u okp4d -f -o cat

View the synchronization process (false - the node is synchronized):

curl http://localhost:26657/status | jq .result.sync_info.catching_up

After your node is fully synchronized, you can proceed to create a validator:

okp4d keys add wallet
#create wallet - SAVE MNEMONIC!!!

We go to the tap and ask for coins
Now the transaction to create the validator:

okp4d tx staking create-validator \ --amount=1000000uknow \ --pubkey=$(okp4d tendermint show-validator) \ --moniker="<NODENAME>" \ --chain-id=okp4-nemeton \ --commission-rate="0.01" \ --commission-max-rate="0.10" \ --commission-max-change-rate="0.01" \ --min-self-delegation="1000000" \ --fees=1000uknow \ --from=wallet \ -y
#change <NODENAME> on name of your node

Explorer


Withdraw rewards

okp4d tx distribution withdraw-rewards $(okp4d keys show wallet --bech val -a) --commission --from wallet --chain-id okp4-nemeton-1 --gas-prices 0.1uknow --gas-adjustment 1.5 --gas auto -y

Delegate 259 KNOW

okp4d tx staking delegate $(okp4d keys show wallet --bech val -a) 259000000uknow --from wallet --chain-id okp4-nemeton-1 --gas-prices 0.1uknow --gas-adjustment 1.5 --gas auto -y
