Chain ID: haqq_11235-1 | Current Node Version: v1.8.2
Our app.toml
settings related to state-sync is as follows.
This is for you information only. You do not need to follow the same
setup on your node.
# Prune Type
pruning = "custom"
# Prune Strategy
pruning-keep-every = 2000
# State-Sync Snapshot Strategy
snapshot-interval = 2000
snapshot-keep-recent = 5
Our state-sync RPC server for Haqq is:
https://haqq-rpc.polkachu.com:443
We assume that you use Cosmovisor to manage your node. If you do not use Cosmovisor, you will need to customize the following instruction slightly.
Create a reusable shell script such as state_sync.sh
with
the
following code. The code will fetch important state-sync information
(such as block height and trust hash) from our server and
update your config.toml
file accordingly.
#!/bin/bash
SNAP_RPC="https://haqq-rpc.polkachu.com: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/.haqqd/config/config.toml
Grant user the privilege to execute script and then run the script:
chmod 700 state_sync.sh
./state_sync.sh
Stop the node:
sudo service haqq stop
Reset the node
# Reset node state
haqqd tendermint unsafe-reset-all --home $HOME/.haqqd --keep-addr-book
Restart the node:
sudo service haqq start
If everything goes well, your node should start syncing within 10 minutes.
ALTERNATIVE ROUTE: We also have Haqq Snapshot Service to help you bootstrap a node.
First, visit our state-sync server landing page to ensure it is not down.
Second, add Polkachu's state-sync server as your peer. You can find Polkachu's peer info here.
Make sure that you use the latest version of the chain node when you state-sync.
State-sync can be flaky at times. Join our Discord Server if you have any issues. Happy State-Syncing!
