  • Mocha testnet is an upgrade of Mamaki testnet. Like Mamaki, there is no reward. This page is for those who are running a Mamaki node and want to upgrade to Mocha.
  • Before proceeding, I recommend that you back up your files related to the Mamaki node.

Hardware Requirements

  • Memory: 8 GB RAM
  • CPU: Quad-Core
  • Disk: 250 GB SSD Storage
  • Bandwidth: 1 Gbps for Download/100 Mbps for Upload

Mamaki Node Stop and Clean Files

sudo systemctl stop celestia-appd
celestia-appd tendermint unsafe-reset-all --home $HOME/.celestia-app
rm -rf celestia-app
rm -rf .celestia-app

Mocha Files

cd $HOME
git clone https://github.com/celestiaorg/celestia-app.git
cd celestia-app/
APP_VERSION=v0.11.0
git checkout tags/$APP_VERSION -b $APP_VERSION

Snapshot

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

Wallet

celestia-appd keys add walletname

celestia-appd keys add walletname --recover

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.

Create Validator

MONIKER="Validator Name"
VALIDATOR_WALLET="Wallet Name"
EVM_ADDRESS=You can add any Ethereum-based address
ORCHESTRATOR_ADDRESS=Validators certainly can use their existing Celestia addresses here but it is recommended to create a new one.


celestia-appd tx staking create-validator \
    --amount=1000000utia \
    --pubkey=$(celestia-appd tendermint show-validator) \
    --moniker=$MONIKER \
    --chain-id=mocha \

    --commission-max-rate=0.2 \
    --commission-max-change-rate=0.01 \
    --min-self-delegation=1000000 \
    --from=$VALIDATOR_WALLET \
    --orchestrator-address=$ORCHESTRATOR_ADDRESS \
    --evm-address=$EVM_ADDRESS \
    --fees 500utia \
    --gas=400671

Delegate to a Validator

celestia-appd tx staking delegate VALIDATOR_ADDRESS 1000000utia --chain-id mocha --fees=300utia --from walletname
