peers scanner:

Stale peers can lead to node inefficiency over time. Below are 4 active peers found by our network scanner. These are verified for decent uptime in real time.

State Sync

If you don't want to wait for a long synchronization you can use:

sudo systemctl stop zenrockd
 
cp $HOME/.zrchain/data/priv_validator_state.json $HOME/.zrchain/priv_validator_state.json.backup
zenrockd tendermint unsafe-reset-all --home $HOME/.zrchain
