Download and Build Binaries

# Clone project repository
cd $HOME
rm -rf symphony
git clone https://github.com/Orchestra-Labs/symphony
cd symphony
git checkout v0.4.1

# Build binaries
make build

# Prepare binaries for Cosmovisor
mkdir -p $HOME/.symphonyd/cosmovisor/genesis/bin
mv build/symphonyd $HOME/.symphonyd/cosmovisor/genesis/bin/
rm -rf build

# Create application symlinks
sudo ln -s $HOME/.symphonyd/cosmovisor/genesis $HOME/.symphonyd/cosmovisor/current -f
sudo ln -s $HOME/.symphonyd/cosmovisor/current/bin/symphonyd /usr/local/bin/symphonyd -f

Install Cosmovisor and create daemon service

# Download and install Cosmovisor
go install cosmossdk.io/tools/cosmovisor/cmd/[email protected]

Initialize the node

# Set node configuration

Download Latest Snapshot & extract the file

curl -L https://snapshot.ravenode.xyz/symphony/symphony-latest.tar.lz4 | tar -Ilz4 -xf - -C $HOME/.symphonyd
[[ -f $HOME/.symphonyd/data/upgrade-info.json ]] && cp $HOME/.symphonyd/data/upgrade-info.json $HOME/.symphonyd/cosmovisor/genesis/upgrade-info.json

Start Service & Check Node Logs

sudo systemctl restart symphony.service && sudo journalctl -u symphony.service -f --no-hostname -o cat

Verify node's block height sync

while true; do
  local_height=$(symphonyd status 2>&1 | jq -r .sync_info.latest_block_height || echo "0")

  network_height=$(curl -s https://rpc.symphony.ravenode.xyz/status | jq -r .result.sync_info.latest_block_height || echo "0")

  blocks_left=$((network_height - local_height))

  n_peers=$(curl -Ss localhost:26657/net_info | jq -r .result.n_peers || echo "0")

  echo "Curr block: $local_height (blocks left: $blocks_left) | Peers: $n_peers"

  sleep 3
done

  • Example Output

Curr block: 194935 (blocks left: 1) | Peers: 47
Curr block: 194936 (blocks left: 0) | Peers: 47
Curr block: 194937 (blocks left: 0) | Peers: 47

If you receive output like the above and "blocks left" is 0, it means the node is fully synced and has reached the latest block height. The node is now up to date with the blockchain and in sync with the other peers.

Spin Up Validator

1. Create a wallet

You have two options for that.

OPTION 1 - CREATE NEW WALLET

symphonyd keys add wallet

Save the mnemonic output as this is the only way to recover your validator wallet in case you lose it!

OPTION 2 - RECOVER EXISTING WALLET

symphonyd keys add wallet --recover

To list your wallets use command below

symphonyd keys list

2. Fund a wallet

To create a validator, you need to fund the previously created wallet using https://testnet.ping.pub/symphony/faucet

To check wallet balance use command below

symphonyd q bank balances $(symphonyd keys show wallet -a)

3. Create Validator

Use the following command to get the your validator pubkey value:

symphonyd tendermint show-validator

Create a validator.json file inside /root/.symphonyd/

nano /root/.symphonyd/validator.json

Copy the following command and paste it into the validator.json file:

{
    "pubkey": {
        "@type": "/cosmos.crypto.ed25519.PubKey",
        "key": "your_validator_pubkey"
    },
    "amount": "1000000note",
    "moniker": "your-moniker-name",
    "identity": "your-keybase-id",
    "website": "your-website",
    "details": "your-details",
    "commission-rate": "0.05",
    "commission-max-rate": "0.2",
    "commission-max-change-rate": "0.01",
    "min-self-delegation": "1"
}

Please make sure you have adjusted key, moniker, identity, details, website to match your values.

Run the create validator command:

symphonyd tx staking create-validator $HOME/.symphonyd/validator.json \
--from=wallet \
--chain-id=symphony-testnet-4 \
--gas-adjustment 1.5 \
--gas-prices 0.025note \
--gas auto

Save the ~/.symphonyd/config/priv_validator_key.json file as this is the only way to recover your validator signing key in case you lose it!

Fill Validator Form

Once your node is synced and you've successfully created a validator, please fill out this form to receive additional faucet tokens for validator bonding: https://forms.gle/98ajH8wXCowVnGZi6

Join Symphony Discord and receive Validator role, submit your validator link and tag the team.
