peers scanner:

Stale peers can lead to node inefficiency over time. Below are 18 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 lavad

cp $HOME/.lava/data/priv_validator_state.json $HOME/.lava/priv_validator_state.json.backup
lavad tendermint unsafe-reset-all --home $HOME/.lava
