Like any Cosmos-SDK chain, the hardware requirements are pretty modest.
- 4x CPUs; the faster clock speed the better
- 8GB RAM
- 100GB of storage (SSD or NVME)
- Permanent Internet connection (traffic will be minimal during testnet; 10Mbps will be plenty - for production at least 100Mbps is expected)
- 8x CPUs; the faster clock speed the better
- 64GB RAM
- 1TB of storage (SSD or NVME)
- Permanent Internet connection (traffic will be minimal during testnet; 10Mbps will be plenty - for production at least 100Mbps is expected)
You can setup your ollo fullnode in few minutes by using automated script below. It will prompt you to input your validator node name!
wget -O ollo.sh https://raw.githubusercontent.com/kj89/testnet_manuals/main/ollo/ollo.sh && chmod +x ollo.sh && ./ollo.sh
You can follow manual guide if you better prefer setting up node manually
When installation is finished please load variables into system
source $HOME/.bash_profile
Next you have to make sure your validator is syncing blocks. You can use command below to check synchronization status
ollod status 2>&1 | jq .SyncInfo
You can state sync your node in minutes by running commands below
sudo systemctl stop ollod
ollod tendermint unsafe-reset-all --home $HOME/.ollo --keep-addr-book
SNAP_RPC="https://node.ollo.zone:443"
LATEST_HEIGHT=$(curl -s $SNAP_RPC/block | jq -r .result.block.header.height); \
BLOCK_HEIGHT=$((LATEST_HEIGHT - 2000)); \
TRUST_HASH=$(curl -s "$SNAP_RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash)
echo $LATEST_HEIGHT $BLOCK_HEIGHT $TRUST_HASH
PEERS="[email protected]:26656,[email protected]:26656,[email protected]:26626,[email protected]:26656,[email protected]:26656,[email protected]:29656,[email protected]:30656,[email protected]:16656,[email protected]:37656,[email protected]:15656"
sed -i -e "s/^seeds *=.*/seeds = \"$SEEDS\"/; s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" $HOME/.ollo/config/config.toml
sed -i -E "s|^(enable[[:space:]]+=[[:space:]]+).*$|\1true| ; \
s|^(rpc_servers[[:space:]]+=[[:space:]]+).*$|\1\"$SNAP_RPC,$SNAP_RPC\"| ; \

s|^(trust_hash[[:space:]]+=[[:space:]]+).*$|\1\"$TRUST_HASH\"|" $HOME/.ollo/config/config.toml
sudo systemctl restart ollod
sudo journalctl -u ollod -f --no-hostname -o cat
To create new wallet you can use command below. Don’t forget to save the mnemonic
ollod keys add $WALLET
(OPTIONAL) To recover your wallet using seed phrase
ollod keys add $WALLET --recover
To get current list of wallets
ollod keys list
Add wallet and valoper address into variables
OLLO_WALLET_ADDRESS=$(ollod keys show $WALLET -a)
OLLO_VALOPER_ADDRESS=$(ollod keys show $WALLET --bech val -a)
echo 'export OLLO_WALLET_ADDRESS='${OLLO_WALLET_ADDRESS} >> $HOME/.bash_profile
echo 'export OLLO_VALOPER_ADDRESS='${OLLO_VALOPER_ADDRESS} >> $HOME/.bash_profile
source $HOME/.bash_profile
In order to create validator first you need to fund your wallet with testnet tokens.
You can request testnet tokens from the OLLO testnet faucet in the OLLO Discord
- Get verified
- Get
Testnet Explorers role
in#roles
channel - Move to
#testnet-faucet
and request tokens
!request YOUR_WALLET_ADDRESS
Before creating validator please make sure that you have at least 1 strd (1 strd is equal to 1000000 utollo) and your node is synchronized
To check your wallet balance:
ollod query bank balances $OLLO_WALLET_ADDRESS
If your wallet does not show any balance than probably your node is still syncing. Please wait until it finish to synchronize and then continue
To create your validator run command below
ollod tx staking create-validator \
--amount 2000000utollo \
--from $WALLET \
--commission-max-change-rate "0.01" \
--commission-max-rate "0.2" \
--commission-rate "0.07" \
--min-self-delegation "1" \
--pubkey $(ollod tendermint show-validator) \
--moniker $NODENAME \
--identity=1C5ACD2EEF363C3A \
--website="http://kjnodes.com" \
--details="Providing professional staking services with high performance and availability" \
--chain-id $OLLO_CHAIN_ID
To protect you keys please make sure you follow basic security rules
Good tutorial on how to set up ssh keys for authentication to your server can be found here
Start by checking the status of ufw.
sudo ufw status
Sets the default to allow outgoing connections, deny all incoming except ssh and 26656. Limit SSH login attempts
sudo ufw default allow outgoing
sudo ufw default deny incoming
sudo ufw allow ssh/tcp
sudo ufw limit ssh/tcp
sudo ufw allow ${OLLO_PORT}656,${OLLO_PORT}660/tcp
sudo ufw enable
To monitor and get alerted about your validator health status you can use my guide on Set up monitoring and alerting for ollo validator
This script will help you to estimate how much time it will take to fully synchronize your node
It measures average blocks per minute that are being synchronized for period of 5 minutes and then gives you results
wget -O synctime.py https://raw.githubusercontent.com/kj89/testnet_manuals/main/ollo/tools/synctime.py && python3 ./synctime.py
