Set up validator

Official documentation: https://docs.celestia.org/nodes/validator-node

1. Create a wallet

First of all we will need to create wallet for our validator. You have two options for that.

Option 1 - Create new wallet

celestia-appd keys add wallet

Option 2 - Recover existing wallet

celestia-appd keys add wallet --recover

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

To list your wallets use command below

celestia-appd keys list

2. Top up wallet with tokens

You can buy tokens at app.osmosis.zone

To check wallet balance use command below

celestia-appd q bank balances $(celestia-appd keys show wallet -a)

3. Create validator

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

celestia-appd tx staking create-validator \
--amount 1000000utia \
--pubkey $(celestia-appd tendermint show-validator) \
--moniker "YOUR_MONIKER_NAME" \
--identity "YOUR_KEYBASE_ID" \
--details "YOUR_DETAILS" \
--website "YOUR_WEBSITE_URL" \
--chain-id celestia \
--commission-rate 0.05 \
--commission-max-rate 0.20 \
--commission-max-change-rate 0.05 \
--min-self-delegation 1 \
--from wallet \
--gas-adjustment 1.4 \
--gas auto \
--gas-prices 0.005utia \
-y

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

Install Bridge Node

Official documentation: https://docs.celestia.org/nodes/bridge-node

Download and build binaries

cd $HOME 
rm -rf celestia-node 
git clone https://github.com/celestiaorg/celestia-node.git 
cd celestia-node
git checkout v0.13.4
make build
sudo mv build/celestia /usr/local/bin
make cel-key
sudo mv cel-key /usr/local/bin

Add Bridge wallet

Generate new wallet

cel-key add bridge-wallet --node.type bridge --p2p.network celestia

Recover existing wallet

cel-key add bridge-wallet --node.type bridge --p2p.network celestia --recover

Fund the wallet with testnet tokens

Once you start the Bridge Node, a wallet key will be generated for you. You will need to fund that address with Testnet tokens to pay for PayForBlob transactions

Initialize Bridge node

celestia bridge init \
  --keyring.accname bridge-wallet \
  --core.ip http://localhost \
  --core.rpc.port 12057 \
  --core.grpc.port 12090 \
  --p2p.network celestia \
  --rpc.port 12058 \
  --gateway.port 12059

Create service

Start Bridge node

systemctl restart celestia-bridge.service

Check Bridge node logs

journalctl -fu celestia-bridge.service -o cat

Useful commands

Get Bridge Node ID

AUTH_TOKEN=$(celestia bridge auth admin --p2p.network celestia)
curl -s -X POST -H "Authorization: Bearer $AUTH_TOKEN" -H 'Content-Type: application/json' -d '{"jsonrpc":"2.0","id":0,"method":"p2p.Info","params":[]}' http://localhost:12058 | jq -r .result.ID

Get Bridge node key

cel-key show bridge-wallet --node.type bridge --p2p.network celestia -a | tail -1

Check Bridge node wallet balance

celestia-appd q bank balances $(cel-key show bridge-wallet --node.type bridge --p2p.network celestia -a | tail -1)

Upgrade Bridge Node

Stop Bridge node

sudo systemctl stop celestia-bridge.service

Download and build binaries

cd $HOME 
rm -rf celestia-node 
git clone https://github.com/celestiaorg/celestia-node.git 
cd celestia-node
git checkout v0.13.4
make build
sudo mv build/celestia /usr/local/bin
make cel-key
sudo mv cel-key /usr/local/bin

Check Bridge node version

celestia version

Node upgrade

To upgrade Celestia Bridge node you have two options

Option 1 - Soft upgrade

This option will only update attributes of configuration files without deleting any data.

Update configuration file

celestia bridge config-update --p2p.network celestia

Option 2 - Hard upgrade

This option will clear data store and re-initialize the node. Keys will not be deleted.

Clear data store and remove configuration file

celestia bridge unsafe-reset-store --p2p.network celestia
rm -rf $HOME/.celestia-bridge-celestia/config.toml

Initialize Bridge node

celestia bridge init \
  --keyring.accname bridge-wallet \
  --core.ip localhost \
  --core.rpc.port 12057 \
  --core.grpc.port 12090 \
  --p2p.network celestia \
  --rpc.port 12058 \
  --gateway.port 12059

Start Bridge node

sudo systemctl start celestia-bridge.service

Check Bridge node logs

journalctl -fu celestia-bridge.service -o cat
