State sync

Stop the service and reset the data

sudo systemctl stop source.service
cp $HOME/.source/data/priv_validator_state.json $HOME/.source/priv_validator_state.json.backup
sourced tendermint unsafe-reset-all --keep-addr-book --home $HOME/.source

Get and configure the state sync information

STATE_SYNC_RPC=https://source.rpc.kjnodes.com:443
STATE_SYNC_PEER=[e-mail]:12856
LATEST_HEIGHT=$(curl -s $STATE_SYNC_RPC/block | jq -r .result.block.header.height)
SYNC_BLOCK_HEIGHT=$(($LATEST_HEIGHT - 1000))
SYNC_BLOCK_HASH=$(curl -s "$STATE_SYNC_RPC/block?height=$SYNC_BLOCK_HEIGHT" | jq -r .result.block_id.hash)

sed -i \
  -e "s|^enable *=.*|enable = true|" \
  -e "s|^rpc_servers *=.*|rpc_servers = \"$STATE_SYNC_RPC,$STATE_SYNC_RPC\"|" \
  -e "s|^trust_height *=.*|trust_height = $SYNC_BLOCK_HEIGHT|" \
  -e "s|^trust_hash *=.*|trust_hash = \"$SYNC_BLOCK_HASH\"|" \

mv $HOME/.source/priv_validator_state.json.backup $HOME/.source/data/priv_validator_state.json

(Optional) Download latest wasm

If the chain does not support copy of the wasm folder, you can download it manually.

curl -L https://snapshots.kjnodes.com/source/wasm_latest.tar.lz4 | lz4 -dc - | tar -xf - -C $HOME/.source

Restart the service and check the log

sudo systemctl start source.service && sudo journalctl -u source.service -f --no-hostname -o cat
