Quick-Sync With Snapshot (This episode is not in the video. But there is no difference. You can enter the codes in order)

cd $HOME
rm -rf ~/.celestia-app/data
mkdir -p ~/.celestia-app/data
SNAP_NAME=$(curl -s https://snaps.qubelabs.io/celestia/ | \
    egrep -o ">mamaki.*tar" | tr -d ">")
wget -O - https://snaps.qubelabs.io/celestia/${SNAP_NAME} | tar xf - \
    -C ~/.celestia-app/data/

Node Start

sudo systemctl enable celestia-appd
sudo systemctl start celestia-appd

Check If Daemon Has Been Started Correctly

sudo systemctl status celestia-appd

• You can exit the status screen by pressing ctrl+c

Check Daemon Logs in Real Time

sudo journalctl -u celestia-appd.service -f

To check If Your Node is in Sync Before Going Forward

curl -s localhost:26657/status | jq .result | jq .sync_info

latest_block_height = compare its value with the explorer value. When they are identical to each other, synchronization to the system is complete.

Connect Validator

celestia-appd tx staking create-validator \
    --amount=1000000utia \
    --pubkey=$(celestia-appd tendermint show-validator) \
    --moniker=MonikerAdi \
    --chain-id=mamaki \
    --commission-rate=0.1 \
    --commission-max-rate=0.2 \
    --commission-max-change-rate=0.01 \
    --min-self-delegation=1000000 \
    --from=walletname

confirm transaction before signing and broadcasting [y/N]: y

Delegate to a Validator

celestia-appd tx staking delegate VALIDATOR_ADDRESS 1000000utia --chain-id mamaki --fees=1utia --from walletname

Unjail

celestia-appd tx slashing unjail --from=walletname --chain-id mamaki

See The Number of Peers You Are Connected to

curl -sS http://localhost:26657/net_info | jq -r '.result.n_peers'

Find Out The Node Address
