Initialise your Validator node

#Choose a name for your validator and use it in place of “<moniker-name>” in the following command:
acred init <moniker-name> --chain-id bamboo_9000-1

#Example
acred init Synergy_Nodes --chain-id bamboo_9000-1

Download genesis.json file

cd ~/.acred/config
rm genesis.json
cd

wget https://raw.githubusercontent.com/ArableProtocol/acrechain/testnet_bamboo/networks/bamboo/genesis.json -O $HOME/.acred/config/genesis.json

Update configuration and peers list

cd

PEERS="[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:36656"

sed -i -e "s/^seeds *=.*/seeds = \"$SEEDS\"/; s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" $HOME/.acred/config/config.toml

Start the node and let it Sync

acred start

# Press Ctrl+c to exit

Running the validator as a systemd unit

cd /etc/systemd/system
sudo nano acred.service

Copy the following content into acred.service and save it.

Execute the folloiwng command to get the node id

acred tendermint show-node-id

Create a Wallet for your Validator Node

Make sure to copy the 24 words Mnemonics Phrase, save it in a file and store it on a safe location.

acred keys add <wallet-name>

#Example
acred keys add my_wallet

The following applys after the network goes live on 13th June 2022

Get some ACRE tokens to the above created wallet.

Create and Register Your Validator Node

acred tx staking create-validator -y \
  --chain-id bamboo_9000-1 \
  --moniker <moniker-name> \
  --pubkey "$(acred tendermint show-validator)" \
  --amount 5000000000000000000uacre \
  --identity "<Keybase.io ID>" \
  --website "<website-address>" \
  --details "Some description" \
  --from <wallet-name> \
  --gas=300000 \
  --commission-rate=0.0 \
  --commission-max-rate=0.05 \
  --commission-max-change-rate=0.01 \
  --min-self-delegation 1
  
#Example

acred tx staking create-validator -y \
  --chain-id bamboo_9000-1 \
  --moniker "Synergy Nodes" \
  --pubkey "$(acred tendermint show-validator)" \
  --amount 5000000000000000000uacre \
  --identity "D74433D32938F013" \
  --website "http://www.mywebsite.com" \
  --details "Some description" \
  --from my_wallet \

  --commission-rate=0.0 \
  --commission-max-rate=0.05 \
  --commission-max-change-rate=0.01 \
  --min-self-delegation 1
  

Get Validator Operator Address (Valoper Address)

Make sure to change <wallet-name> to correct values.

acred keys show <wallet-name> --bech val --output json | jq -r .address

#Example
acred keys show my_wallet --bech val --output json | jq -r .address

Delegate ACRE to Your Node

acred tx staking delegate <validator-address> 1000000uacre --from <wallet-name> --chain-id bamboo_9000-1 -y

#Example
acred tx staking delegate acrevaloper1y4pfpkwpy6myskp7pne256k6smh2rjtay37kwc 1000000uacre --from my_wallet --chain-id bamboo_9000-1 -y

Backup Validator node file

Take a backup of the following files after you have created and registered your validator node successfully.

/home/node/.acred/config/node_key.json
/home/node/.acred/config/priv_validator_key.json
/home/node/.acred/data/priv_validator_state.json

Withdraw Rewards

Make sure to change <validator-operator-address>, <wallet-name> to correct values.

acred tx distribution withdraw-rewards <validator-address> --from <wallet-name> --chain-id=bamboo_9000-1 -y

#Example
acred tx distribution withdraw-rewards acrevaloper1y4pfpkwpy6myskp7pne256k6smh2rjtay37kwc --from synergy --chain-id=bamboo_9000-1 -y

Check Balance of an Address

acred query bank balances <wallet-address>

#Example:
acred query bank balances acre1y4pfpkwpy6myskp7pne256k6smh2rjtaaf0xv9
