Why Neutaro

Neutaro is closely working with Timpi to help create the first truly decentralized search engine! On Neutaro, you can claim rewards for contributing to Timpi and vote on different proposals affecting Timpi, such as those regarding the ethical standpoint of the Timpi search engine.

Neutaro Validator Security Guide

For more details on security, please check the Security Guide.

Introduction

Running a node means that you run the chains binary. Follow these steps to create a Validator that runs as a service on linux.
You can be a part of Neutaro by holding tokens and delegating them, running a node, or becoming a validator.

Delegating Tokens

By delegating your tokens to a validator, you increase the amount of staked tokens they have, thereby increasing their voting power. In return, you receive a share of their rewards based on the amount you have delegated.

To delegate your tokens to a Validator, use the command below. 1,000,000 uneutaro is equal to 1 NTMPI. If you want to stake 100 NTMPI tokens, you input 100000000uneutaro into the command.

Example Command:

Neutaro tx staking delegate ValidatorAddress 1000000uneutaro --from YOURWALLET --chain-id Neutaro-1

Before Running a Node

Open Port 26656 for Better Connectivity

To improve network connectivity and allow your node to share seeds with others, you need to open port 26656 on both your Linux firewall and router.

1. Open Port 26656 on Linux Firewall (UFW):

Run the following commands to allow traffic on port 26656:

sudo ufw allow 26656/tcp
sudo ufw reload

2. Open Port 26656 on Your Router:

Ensure port 26656 is open for TCP traffic in your router's Port Forwarding settings.

Opening port 26656 helps with better network performance and faster synchronization.

Running a node

We suggest using Ubuntu 22.04.03, 4 cores, 8gb RAM and 250-500gb of free storage. The storage will increase overtime, but with the suggested pruning and current state of the chain it's fine and it will be fine for a few more months.

Automated Removal of Neutaro Validator

To automatically remove the Neutaro installation, use this command:

bash <(wget -qO- https://raw.githubusercontent.com/Neutaro/Neutaro/main/neutaro_remove.sh)

Validator's Best Friend: The Neutaro Help Command

Before diving into specific commands, remember that the most valuable tool for any validator is the Neutaro help command. This command provides a comprehensive list of all available commands and their descriptions, making it easier for validators to find exactly what they need. Use it regularly to stay updated:

Neutaro help

This will display all the commands, their descriptions, and available flags for customization.

Step 1: Manual Setup - Update System and Install Dependencies

We suggest using Ubuntu 22.04.03, 4 cores, 8gb RAM and 250-500gb of free storage. The storage will increase overtime, but with the suggested pruning and current state of the chain it's fine and it will be fine for a few more months.

Step 1: Install Required Dependencies

Run the following command to install essential dependencies:

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

Step 2: Install Go

GO_VERSION="1.22.2"
wget "https://golang.org/dl/go$GO_VERSION.linux-amd64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$GO_VERSION.linux-amd64.tar.gz"
rm "go$GO_VERSION.linux-amd64.tar.gz"

Ensure Go is accessible for both user and sudo

echo "export PATH=/usr/local/go/bin:$HOME/go/bin:$PATH" | tee -a ~/.bash_profile ~/.bashrc
source ~/.bash_profile

Fix sudo not recognizing Go

sudo ln -sf /usr/local/go/bin/go /usr/bin/go

Verify Go installation:

go version
sudo go version

Step 3: Clone and Build Neutaro

cd $HOME
git clone https://github.com/Neutaro/Neutaro
cd Neutaro
make build

Check the Neutaro version:

./build/Neutaro version --long

Move the new binary to the Cosmovisor upgrade directory:

mkdir -p $HOME/.Neutaro/cosmovisor/upgrades/v2/bin
cp build/Neutaro $HOME/.Neutaro/cosmovisor/upgrades/v2/bin

Verify the upgrade:

$HOME/.Neutaro/cosmovisor/upgrades/v2/bin/Neutaro version --long

Step 4: Install Cosmovisor

go install cosmossdk.io/tools/cosmovisor/cmd/cosmovisor@v1.4.0
mkdir -p $HOME/.Neutaro/cosmovisor/genesis/bin
cp build/Neutaro $HOME/.Neutaro/cosmovisor/genesis/bin
ln -s $HOME/.Neutaro/cosmovisor/genesis $HOME/.Neutaro/cosmovisor/current
sudo ln -s $HOME/.Neutaro/cosmovisor/current/bin/Neutaro /usr/local/bin/Neutaro

Step 5: Initialize the Node

Replace YourMonikerName with your desired moniker:

MONIKER="YourMonikerName"
Neutaro init $MONIKER --chain-id Neutaro-1

Step 6: Configure the Node

Edit configuration files using sed commands:

sed -i "s/^seeds *=.*/seeds = \"84ae242b0c4c14af59a61438ba2eca4573b91c95@109.199.106.233:26656,0e24a596dc34e7063ec2938baf05d09b374709e6@109.199.106.233:26656\"/" $HOME/.Neutaro/config/config.toml
sed -i "s/^pruning *=.*/pruning = \"custom\"/" $HOME/.Neutaro/config/app.toml
sed -i "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"100\"/" $HOME/.Neutaro/config/app.toml
sed -i "s/^pruning-interval *=.*/pruning-interval = \"19\"/" $HOME/.Neutaro/config/app.toml

Download the genesis file:

curl -f http://154.26.153.186/genesis.json > ~/.Neutaro/config/genesis.json

Step 7: Apply Snapshot

Download and extract the snapshot:

cd $HOME/.Neutaro
SNAPSHOT_URL="http://173.212.198.246/snapshot-neutaro/latest.tar.lz4"
wget $SNAPSHOT_URL -O latest.tar.lz4
lz4 -t latest.tar.lz4  # Check if the file is valid
if [ $? -eq 0 ]; then
    lz4 -d latest.tar.lz4 | tar -xvf - -C $HOME/.Neutaro
    rm -f latest.tar.lz4
else
    echo "❌ Snapshot file is corrupted. Download again."
    rm -f latest.tar.lz4
fi

Check the extracted files:

ls -l $HOME/.Neutaro

Step 8: Configure the Systemd Service

Create the Neutaro.service file using nano:

sudo nano /etc/systemd/system/Neutaro.service

To get your <your-username> use this command in terminal: whoami

Replace all occurrences of <your-username> in the following parts of the command:

User=<your-username> [e.g. User=BobSmith ]

/home/<your-username>/go/bin/cosmovisor [e.g. /home/BobSmith/go/bin/cosmovisor ]

Environment="DAEMON_HOME=/home/<your-username>/.Neutaro" [e.g. Environment="DAEMON_HOME=/home/BobSmith/.Neutaro ]

Replace <your-username> in 3 places:

sudo tee /etc/systemd/system/Neutaro.service > /dev/null << EOF
[Unit]
Description=Neutaro Node Service
After=network-online.target

[Service]
User=<your-username>
ExecStart=/home/<your-username>/go/bin/cosmovisor run start
Restart=on-failure
RestartSec=10
LimitNOFILE=65535
Environment="DAEMON_HOME=/home/<your-username>/.Neutaro"
Environment="DAEMON_NAME=Neutaro"
Environment="UNSAFE_SKIP_BACKUP=true"

[Install]
WantedBy=multi-user.target
EOF

Step 9: Enable and Start the Service

Reload the systemd daemon and enable the service:

sudo systemctl daemon-reload
sudo systemctl enable Neutaro
sudo systemctl restart Neutaro

Note

It can take up to 3h before it starts to sync.

Check the logs:

sudo journalctl -fu Neutaro -o cat

Step 10: Verify Sync Status

Run the following command to verify the node's sync status:

Neutaro status 2>&1 | jq .SyncInfo

Step 11: Become a Validator

Create or recover a wallet:

sudo Neutaro keys add WALLET --keyring-backend os --recover

Send the validator transaction. Make sure you are fully synced before you send the command. (update parameters as needed in example below):

Neutaro tx staking create-validator \
--amount=1000000uneutaro \
--pubkey=$(Neutaro tendermint show-validator) \
--moniker="YourName" \
--chain-id=Neutaro-1 \
--from=WALLET \
--keyring-backend=os \
--commission-rate="0.10" \
--commission-max-rate="0.20" \
--commission-max-change-rate="0.01" \
--min-self-delegation="1000000" \
--details="Your validator details"

Congratulations! Your Neutaro validator should now be set up and running.
