StateSync

Instruction

Create a shell script as `sync.sh`

#!/bin/bash

SNAP_RPC="https://c4e-rpc.kalia.network:443"

LATEST_HEIGHT=$(curl -s $SNAP_RPC/block | jq -r .result.block.header.height); \
BLOCK_HEIGHT=$((LATEST_HEIGHT - 2000)); \
TRUST_HASH=$(curl -s "$SNAP_RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash)

sed -i.bak -E "s|^(enable[[:space:]]+=[[:space:]]+).*$|\1true| ; \
s|^(rpc_servers[[:space:]]+=[[:space:]]+).*$|\1\"$SNAP_RPC,$SNAP_RPC\"| ; \
s|^(trust_height[[:space:]]+=[[:space:]]+).*$|\1$BLOCK_HEIGHT| ; \
s|^(trust_hash[[:space:]]+=[[:space:]]+).*$|\1\"$TRUST_HASH\"|" $HOME/.c4e-chain/config/config.toml

cp $HOME/.c4e-chain/data/priv_validator_state.json $HOME/.c4e-chain/priv_validator_state.json.backup

Stop the service and reset the data

sudo systemctl stop c4ed
c4ed tendermint unsafe-reset-all --home $HOME/.c4e-chain

Run these codes after created `sync.sh`

chmod +x sync.sh
./sync.sh

Restart the service

cp $HOME/.c4e-chain/priv_validator_state.json.backup $HOME/.c4e-chain/data/priv_validator_state.json
sudo systemctl restart c4ed 

Check the logs

sudo journalctl -u c4ed -f -o cat --no-hostname
