Empeiria's Testnet

Testnet

We recommend the following hardware specifications:

Characteristic	Specification
Operating System	Ubuntu 18.04 or later LTS
Number of CPUs	6
RAM	32GB
SSD	240GB

Update :

sudo apt update && sudo apt upgrade -y

sudo apt install -y git gcc make unzip jq

GO :

cd $HOME
VER="1.22.3"
wget "https://golang.org/dl/go$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"
[ ! -f ~/.bash_profile ] && touch ~/.bash_profile
echo "export PATH=$PATH:/usr/local/go/bin:~/go/bin" >> ~/.bash_profile
source $HOME/.bash_profile
[ ! -d ~/go/bin ] && mkdir -p ~/go/bin

Add Go to the path:

echo 'export PATH=$PATH:/usr/local/go/bin' >> ~/.profile
echo 'export PATH=$PATH:/home/$USER/go/bin' >> ~/.profile

source ~/.profile

Install binary from source code :

If you want acsess file mail : [email protected]

git clone --depth 1 --branch  release/v0.1.0  https://github.com/empe-io/empe-chain

cd empe-chain/
make install

Check binary version should be equal :

emped version

Result : output: v0.1.0

Configure a node

Change "Your Moniker"

export CHAINID=empe-testnet-2
export MONIKER=your moniker 

Init chain and delete generated genesis:

emped init $MONIKER --chain-id $CHAINID
rm -rf ~/.empe-chain/config/genesis.json

Clone repository with chains:

git clone https://github.com/empe-io/empe-chains.git   

cd empe-chains/testnet-2/

Copy genesis file from repo :

cp genesis.json ~/.empe-chain/config/

Change the persistent peers inside config.toml file:

sed -e "s|persistent_peers = \".*\"|persistent_peers = \"$(cat .data | grep -oP 'Persistent peers\s+\K\S+')\"|g" ~/.empe-chain/config/config.toml > ~/.empe-chain/config/config.toml.tmp
mv ~/.empe-chain/config/config.toml.tmp  ~/.empe-chain/config/config.toml 

Set minimum gas price in app.toml file :

sed -e "s|minimum-gas-prices = \".*\"|minimum-gas-prices = \"$(cat .data | grep -oP 'Minimum Gas Price\s+\K\S+')\"|g" ~/.empe-chain/config/app.toml > ~/.empe-chain/config/app.toml.tmp
mv ~/.empe-chain/config/app.toml.tmp  ~/.empe-chain/config/app.toml

Change external_address value to contact your node using the public IP of your node:

PUB_IP=`curl –s –4 icanhazip.com`
sed -e "s|external_address = \".*\"|external_address = \"$PUB_IP:26656\"|g" ~/.empe-chain/config/config.toml > ~/.empe-chain/config/config.toml.tmp
mv ~/.empe-chain/config/config.toml.tmp  ~/.empe-chain/config/config.toml

Cosmovisor setup

go install cosmossdk.io/tools/cosmovisor/cmd/[email protected]

Create dir structure for cosmovisor :

export DAEMON_NAME=emped
export DAEMON_HOME=$HOME/.empe-chain/
mkdir -p $DAEMON_HOME/cosmovisor/genesis/bin
mkdir -p $DAEMON_HOME/cosmovisor/upgrades

Copy emped binary to cosmovisor genesis bin :

cp ~/go/bin/emped $DAEMON_HOME/cosmovisor/genesis/bin
$DAEMON_HOME/cosmovisor/genesis/bin/emped version

Setup systemd :

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

Run a node:

sudo systemctl enable cosmovisor  

sudo systemctl start cosmovisor

Check status :

sudo systemctl status cosmovisor

Logs from cosmovisor :

sudo journalctl -f -u cosmovisor

Full state sync from archive snapshot

curl -O https://archive-testnet.empe.io/$ARCHIVE
tar -xvf $ARCHIVE -C ~/.empe-chain/data
rm $ARCHIVE

sudo systemctl daemon-reload

sudo systemctl restart

Run a Validator

Requirements :

emped status | jq .SyncInfo.catching_up

Result : false

Add wallet key ( change wallet ( wallet : walletname) )

emped keys add wallet

Example - Looks like a :

emped keys add validator
Enter keyring passphrase:
Re-enter keyring passphrase:

- name: validator
  type: local
  address: empe1atqq8lmeptgn2jlx2q8r42p572yhh6lzle7vng
  pubkey: '{"@type":"/cosmos.crypto.secp256k1.PubKey","key":"A8D47crCW+YkFGduj6brpuzectp3D61xRIx/qbEGGTif"}'
  mnemonic: ""

Create Your Validator :

emped tendermint show-validator

Change - Keyname - validator name :

emped tx staking create-validator \
  --amount=10000000uempe \
  --pubkey=$(emped tendermint show-validator) \
  --moniker=<YOUR_MONIKER> \
  --chain-id=empe-testnet-2\
  --commission-rate="0.10" \
  --commission-max-rate="0.20" \
  --commission-max-change-rate="0.01" \
  --gas="auto" \
  --min-self-delegation="1000000" \
  --fees=20uempe \
  --from=<KEY_NAME>

Check Your Validator :

emped query tendermint-validator-set | grep "$(emped tendermint show-validator | jq .key  | tr -d \")"

SAVE THIS FILE !!!!!!!!!!!!!!!!!! SAVE !
