source $HOME/.cargo/env
curl https://get.ignite.com/cli | bash
sudo mv ignite /usr/local/bin/

Go installation.

sudo rm -rf /usr/local/go
curl -L https://go.dev/dl/go1.21.6.linux-amd64.tar.gz | sudo tar -xzf - -C /usr/local
echo 'export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin' >> $HOME/.bash_profile
source .bash_profile
go version

Download and build binaries

rm -rf $HOME/aligned_layer_tendermint

Reset and download snapshot

alignedlayerd tendermint unsafe-reset-all --home $HOME/.alignedlayer
if curl -s --head curl https://testnet-files.itrocket.net/alignedlayer/snap_alignedlayer.tar.lz4 | head -n 1 | grep "200" > /dev/null; then
  curl https://testnet-files.itrocket.net/alignedlayer/snap_alignedlayer.tar.lz4 | lz4 -dc - | tar -xf - -C $HOME/.alignedlayer
    else
  echo no have snap
fi

enable and start service

sudo systemctl start alignedlayerd
sudo systemctl start alignedlayerd

Becoming a Validator

Create wallet key new

alignedlayerd keys add $WALLET

(OPTIONAL) RECOVER EXISTING KEY

alignedlayerd keys add $WALLET --recover

check sync status, once your node is fully synced, the output from above will print "false"

alignedlayerd status 2>&1 | jq

We receive tokens from the tap in the discord

faucet not work

before creating a validator, you need to fund your wallet and check balance

alignedlayerd q bank balances $WALLET_ADDRESS

Create validator

alignedlayerd tx staking create-validator \
--amount 1000000stake \
--from $WALLET \
--commission-rate 0.1 \
--commission-max-rate 0.2 \
--commission-max-change-rate 0.01 \
--min-self-delegation 1 \
--pubkey $(alignedlayerd tendermint show-validator) \
--moniker "$MONIKER" \
--identity "FFB0AA51A2DF5955 " \
--details "I love YTWO❤️" \
--chain-id alignedlayer \
--fees 50stake \
-y

Useful commands

Check balance

alignedlayerd q bank balances $WALLET_ADDRESS

CHECK SERVICE LOGS

sudo journalctl -u alignedlayerd -f

RESTART SERVICE

sudo systemctl restart alignedlayerd

GET VALIDATOR INFO

alignedlayerd status 2>&1 | jq

DELEGATE TOKENS TO YOURSELF

alignedlayerd tx staking delegate $(alignedlayerd keys show $WALLET --bech val -a) 1000000stake --from $WALLET --chain-id alignedlayer --fees 50stake -y

REMOVE NODE Please, before proceeding with the next step! All chain data will be lost! Make sure you have backed up your priv_validator_key.json!

sudo systemctl stop alignedlayerd && sudo systemctl disable alignedlayerd && sudo rm /etc/systemd/system/alignedlayerd.service && sudo systemctl daemon-reload && rm -rf $HOME/.alignedlayerd && rm -rf alignedlayerd && sudo rm -rf $(which alignedlayerd)
