Enable and start service

sudo systemctl daemon-reload
sudo systemctl enable celestia-appd
sudo systemctl start celestia-appd

sudo journalctl -u celestia-appd -f -o cat

After successful synchronisation we recommend to turn off snapshot_interval and state sync, this will save space on your hardware.

snapshot_interval=0

Wallet creation

Create wallet

⚠️ store seed phrase, important during recovering

celestia-appd keys add <YOUR_WALLET_NAME>

Recover wallet

⚠️ store seed phrase, important during recovering

celestia-appd keys add <YOUR_WALLET_NAME> --recover

Validator creation

After successful synchronisation we can proceed with validation creation.

Create validator

celestia-appd tx staking create-validator \
--amount=1000000utia \
--pubkey=$(celestia-appd tendermint show-validator) \
--moniker="<Your moniker>" \
--identity=<Your identity> \

Install 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 v0.22.2-mocha
make build
sudo mv build/celestia $HOME/go/bin
make cel-key
sudo mv cel-key $HOME/go/bin

Add new bridge wallet

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

Recover existent bridge wallet (in case you already have bridge wallet)

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

⚠️ Once you start the Bridge Node, a wallet key will be generated. You need to fund that address with testnet tokens (could be used faucet) to pay for PayForBlob transactions

Initialize Bridge node

celestia bridge init \
--keyring.keyname bridge-wallet \
--core.ip http://localhost \
--core.port 9090 \
--p2p.network mocha \
--rpc.port 26658 \
--gateway.port 26659
