How to become a validator?
Node | CPU | RAM | Storage | Type |
|---|---|---|---|---|
Validator | 8 cores | 16 GB | 500 GB | Minimum |
Validator | 8 cores | 32GB | upto 2 TB | Recommended |
sudo apt-get update
sudo apt-get install -y make gcc
- We are using version 1.19.3 for this tutorial.
Amd-64
Arm-64

- The following commands will install the gaia binaries onto your system.
- For this tutorial we are using the 7.1.0 version of gaia.
https://github.com/cosmos/gaia.git
git reset --hard 5db8fcc9a229730f5115bed82d0f85b6db7184b4
cd gaia && make install
- For this tutorial we are configuring our node to run on the theta-testnet-001.
- The following commands will configure our node files in order to join the testnet.
cd gaia
make install
gaiad init <custom_moniker>
wget https://github.com/hyphacoop/testnets/raw/add-theta-testnet/v7-theta/public-testnet/genesis.json.gz
gzip -d genesis.json.gz
mv genesis.json $HOME/.gaia/config/genesis.json
cd $HOME/.gaia/config
sed -i 's/minimum-gas-prices = ""/minimum-gas-prices = "0.001uatom"/' app.toml
sed -i 's/seeds = ""/seeds = "639d50339d7045436c756a042906b9a69970913f@seed-01.theta-testnet.polypore.xyz:26656,3e506472683ceb7ed75c157[email protected]:26656"
- State sync is a endpoint provider which serves the snapshots at every 1000 blocks.
- Using state sync enables us to quickly sync our node to the latest block height.
cd $HOME/.gaia/config
sed -i 's/enable = false/enable = true/' config.toml
sed -i 's/trust_height = 0/trust_height = <LATEST_BLOCK_HEIGHT - 1000>/' config.toml
sed -i 's/trust_hash = ""/trust_hash = "<LATEST_BLOCK_HASH - 1000>"/' config.toml
sed -i 's/rpc_servers = ""/rpc_servers = "rpc.sentry-01.theta-testnet.polypore.xyz:26657,rpc.sentry-02.theta-testnet.polypore.xyz:26657"/' config.toml
- Once we are done configuring our files. We can start running our node which can sync to the latest blockheight.
- To start the node as a service. Perform the following steps.
cd /home/ubuntu/ && sudo nano cosmos.service
[Unit]
Description=service file to run gaia
After=network.target
[Service]
ExecStart=/home/ubuntu/go/bin/gaiad start --x-crisis-skip-assert-invariants
Restart=on-failure
RestartSec=10
Type=simple
User=ubuntu
LimitNOFILE=4096
[Install]
WantedBy=multi-user.target
sudo systemctl enable cosmos.service
sudo systemctl start cosmos.service
journalctl -fu cosmos.service
curl http://localhost:26657/status | grep "catching_up"
- If the above command returns false. This means your node is synced to the latest block height.
- Now, you can run the command to become a validator.
You cannot perform any transaction on the cosmos blockchain if your node is not synced to the latest block height.
Note: You need to have a full node running and synced before you become a validator.
- In this tutorial we are running our own node, so we will configure tcp://localhost:26657 for our validator.
- Paste the following command
gaiad config node tcp://localhost:26657
gaiad config chain-id theta-testnet-001
- The following command will generate a key file which will be used to sign blocks onto the cosmos blockchain
cd /home/ubuntu/.gaia
gaiad keys add <Name_For_Your_Key>
Note: A mnemonic seed phase will be generated when you create a key. We can then use this seed phase to import our account into keplr wallet.
Prerequisites:
Steps to import your account
- 1.Open the keplr wallet chrome extension.
- 2.Click on add account.
- 3.Select import existing account.
- 4.Enter the seed phase that was generated in the previous step.
- 5.Done, you have now successfully imported you account into the keplr wallet.
We need to keep the following things in mind before sending a transaction for becoming a validator:
- We need to stake at least 1 atom.
- Before sending the transaction the full node we are using should be synced to the latest block height.
- Once create-validator transaction is sent, we cannot withdraw atoms for next 21 days. This is also referred to as lock up period.
